Annual work summary of water supply and drainage designers

Annual work summary, a water supply and drainage designer will write a summary every year, affirming our own work and making a contribution to the company's development. Now our enterprise is developing rapidly. The long-term stable development of our company must first do a good job in differentiated service and management, and do a solid job in daily basic work. Let our brand manufacturers and manufacturers join hands with us to create a better tomorrow, and let our God customers enter the splendor and feel the warmth and comfort of home. Let our gorgeous existence have far-reaching significance.

Our property department is responsible for the safety, electricity consumption, cleaning, water heating and air conditioning of shopping malls, and each position is very important and indispensable. When customers enter our shopping mall, they will first feel the warmth and comfort of property services. A warm greeting and a warm smile will make customers feel the warmth of home and the culture brought by a household product. The maintenance of water heating, cleaning, central air conditioning and other property facilities and equipment is relatively trivial, which requires each of us to truly implement the sense of responsibility is very important. In the next 20xx years, everyone will have new gains, and in the face of the rapid development of enterprises, everyone has something to correct. If an enterprise wants to develop, all employees must unite as one, pay attention to details, improve services in an all-round way, enhance gorgeous reputation, and make our road wider and wider.

1.( 1) The maintenance and management of water heating facilities and equipment is more solid and transparent. At the beginning of the year, the goal and plan of water heating work were formulated, the creativity and intelligence of personnel were fully mobilized, and the communication with factory engineers on the operation, maintenance and maintenance of central air conditioning was carried out, and all staff studied the direct-fired engine system and applied it to practice. For the maintenance of central air-conditioning auxiliaries, we have done the original work. We participated in some aging equipment, and put forward suggestions to focus on solving problems in the operation of some units. For the problems encountered in previous years, we should consider in advance and give priority to prevention. For the work of energy saving and consumption reduction, carefully design and consider the operation method, and minimize the data of previous years and maximize the effect on the basis of achieving the effect. After a return visit to the property management, the satisfaction rate of the booth is over 98%. In the heat preservation work of shopping malls, taking advantage of the opportunity of merchants' decoration and purchasing materials, some cold spots were treated with heat preservation, and good results were achieved. Keep in mind the energy-saving goals set by the mall and change from passive work to active work.

(2) The change of service consciousness and service attitude of all staff is a highlight of our work. In view of the overall goal of smiling service and happy work put forward by the company, each of us understands it attentively and runs through the specific work with emotion. To achieve good results, a word is extremely appropriate, and a heartfelt smile is the happiest and most beautiful smile. The good image of the company comes from everyone's sincere experience and achievements. Merchants, customers and brand manufacturers are a whole, and problems in each link will affect the overall development of shopping malls. Therefore, we are more perfect and active in serving customers and businesses. Take their affairs as your own business and their comfort as your own empathy.

(3) The cultivation and growth of personnel is the magic weapon for the long-term development of enterprises. Without improving the comprehensive quality of personnel, it is difficult for enterprises to become bigger and stronger. Only everyone knows the importance of learning, which is the absolute key to success. Through technical exchanges, everyone has been comprehensively promoted. By studying the advanced management experience in books, we can see more clearly that only by arming our minds with knowledge and adding our own skills can we become the compound talents needed by enterprises. After nearly a year's study, each of us has made great progress. We get along more harmoniously between superiors and subordinates, between peers, and between departments, never understanding to understanding, and from passivity to initiative. Network promotion, which is the highlight of property managers in 20xx years, is very gratifying. Some of our comrades can do long-term online promotion for the long-term growth of the company, asking for the development of the company without asking for anything in return. These are all the growth that learning brings us.

2. Enterprise development, break through the shackles of bottlenecks and move towards success. Working in Huamei, our greatest experience is that this is a learning team and an excellent team. Our leaders have lofty and outstanding goals and efficient management concepts, which are not available in other enterprises. This is also where we feel most comfortable. Everyone can closely link their own destiny with the fate of the enterprise, and regard the rise and fall of the enterprise as their own. We are not afraid of the biggest risks and difficulties and the strongest competitors. Only by perfecting your work and paying attention to details can you enjoy the joy of success.

3. Good vision and good expectations will be the driving force for our growth. The development of enterprises depends on the steering direction of leaders, and the navigation depends on everyone's help. Therefore, we hope that our enterprise can give more opportunities for learning and growth, so that our thinking and pace can keep up with the pulse of enterprise development and growth. The enterprise is a big family, and everyone is like brothers. Only in this way can we unite and forge ahead in the fierce market competition in the future.

Annual work summary II. Water supply and drainage designer joined XXXXXXXXX Company in XXX and worked in XXX. I got the title of assistant engineer in XXX, and have been engaged in XXX for X years. In these X years, I have been down-to-earth, working hard and studying hard, and my level in all aspects has been greatly improved through continuous practice.

I. Job responsibilities

During these X years of construction projects, I gradually realized that I have to shoulder a great sense of responsibility in construction work, because my achievements are not only responsible for myself, the unit, the owner, but also the society. Once completed, it will affect for decades and have a great impact on this society. Therefore, while doing my job conscientiously, I try my best to learn all kinds of new norms and technologies, and constantly improve my personal technical level and professional quality. Take the initiative to consult relevant norms and materials when encountering problems, and ask old comrades for advice. In the actual engineering service, we actively communicated with the owner, coordinated with the relevant government departments, actively provided technical support to the construction unit, and tried our best to provide post-project service, which won favorable comments from all walks of life.

Second, the professional and technical ability

In my technical work, I am rigorous, practical and enterprising. Through self-study, training and communication with professionals, I constantly improve my professional technical ability, actively accept new technologies, new materials, new ideas and new methods in my work, master all kinds of office software skillfully, embody what I have learned in practical projects, and correctly handle the relationship between the owner's economic requirements and building principles. During this period, I also participated in many trainings, such as "XXXXXX" organized by XX Construction Bureau in XX Hotel and "XXXXXX" held in the conference room on the third floor of the unit. In this XXX year, I deeply realized that for our younger generation, the technical pursuit of the construction industry is endless. Although I walked a lot of detours and experienced a lot of confusion during the period, with my own efforts and the help of my colleagues, I walked step by step, and my scheme design ability gradually improved and my technology gradually matured. Being able to communicate and coordinate with the owner alone, communicate with the competent government departments and deal with on-site construction problems truly reflects the level of an engineer. While making continuous progress, we should not forget to take the initiative to help young comrades, so that they can master various technologies more quickly and grow rapidly.

Third, specific work.

My work is mainly responsible for the pre-preparation, mid-term construction and post-inspection of water supply and drainage construction technologies and measures.

(A) the construction preparation stage of water supply and drainage construction technology and measures

1, scientific design review of water supply and drainage engineering construction drawing.

In building engineering, drawing design is the first step of the project, and the drawing design requirements of building water supply and drainage pipelines are relatively high, which requires the construction unit to proceed from reality and specifically consider the construction conditions of the construction area, especially the geographical conditions. It mainly includes the investigation of strata, groundwater level and other related situations. At the same time, according to the scale of the city, the structure and size of water supply and drainage pipelines are reasonably designed on the premise of fully considering water supply and drainage. Construction drawing design can meet the needs of urban water supply and drainage, which is the premise of reasonable water supply and drainage pipeline.

After the design of water supply and drainage pipeline construction drawings is completed, the construction personnel must have a deep understanding of the drawings. Urban pipeline is a system, not isolated, so all links in the construction process are interrelated. Construction personnel must have a certain understanding of the whole project, master the geographical situation of the construction area in detail, and ensure the accuracy of construction.

2, strict requirements for pipeline materials.

In order to ensure that the construction results have a certain quality effect and meet people's construction requirements, it is necessary to arrange special personnel to strictly control the entry of each batch of drainage pipeline materials. Professionals include material engineers, quality inspectors, security officers, technicians, etc. Building unit. They mainly check the types, specifications and appearance of materials in detail, which can fully ensure that there are no obvious scratches and wear on the surface of materials, and the appearance and color of materials should be uniform. The manufacturers of materials should have corresponding certificates and provide qualified reports. It is necessary to ensure that the materials are well inspected to the greatest extent. Mainly because even the materials produced by the same manufacturer, the raw materials used will have quality problems to varying degrees. Only after obtaining the certificate of conformity with the construction requirements can the corresponding materials be approved to enter the construction site.

3, pay-off measurement work, keep the accuracy of the measurement.

In the process of water supply and drainage pipeline construction, the setting-out measurement is easy to produce errors. What I have to do is to control the error within the allowable range, and if the error exceeds, it will be unqualified. Therefore, in the setting-out survey, construction technicians must strictly follow the steps and specifications of construction survey to ensure the accuracy of the survey.

(2) Water supply and drainage construction technology and measures in the construction stage

1, and timely reserve holes and casings.

In the construction stage of civil foundation and main structure, when the drainage pipe and water inlet pipe pass through the building, the construction technicians should follow up and check whether the water supply and drainage installation is required to reserve holes and set sleeves. The reserved and embedded personnel shall be familiar with the drawings, positions and specifications of all reserved holes and embedded sleeves to ensure the accuracy of reserved and embedded. The technicians must ask the construction personnel to bury the water supply and drainage pipes on the first floor and do a good job of anticorrosion, and then backfill them indoors. The construction unit will also temporarily block the reserved pipeline. Pay attention to the position of sanitary ware and the arrangement of kitchen and bathroom pipelines to avoid damaging the pipelines during installation. To install waterproof casing accurately, the casing shall not be skewed or deviated, and the inner edge of the casing mouth shall be chamfered to remove welding slag and burr edges. Steel casing is used for the casing crossing the shear wall. Casing shall be made according to design and specification requirements. When embedded, positioning and rechecking should be done. If there is any deviation, it should be adjusted in time.

2, the main pipe and riser production and installation stage

The construction work at this stage includes: fabrication and installation of supports and hangers, fabrication and installation of risers, and fabrication and installation of supervisors. The key points of quality control at this stage are as follows: (1) The quality of pipeline production, especially the sheathing of galvanized steel pipes, should be strictly controlled, and the pipeline connection interface should be tight; (2) Before the riser is installed, a vertical line should be hung to ensure the verticality of the pipeline; (3) The pipeline is installed firmly, and the installation of steam-water supports meets the specification requirements; (4) Expansion joints should be installed on plastic pipes, and inspection ports should be set on drainage risers according to specifications; (5) The concealed pipe in the pipeline well shall be concealed and accepted before concealment. When there is a water supply riser in the pipeline well, pressure test should be carried out, and it can be concealed only after it is qualified; (6) When the riser installation construction is interrupted, the upper nozzle must be covered to prevent sundries from entering.

3, branch pipe and accessories production and installation stage

(1) branch pipe installation method

There are two ways to install water supply branch pipes: concealed installation and exposed installation. Buried pipelines need to be dug in brick walls or on the ground, and then covered with mortar after installation and acceptance. Although this installation method can better meet the aesthetic requirements, it is rarely used in the construction of rough houses, because it will have a certain impact on the construction quality and pipeline maintenance is also difficult. The exposed water supply branch pipe is laid along the wall, and the pipe clamp needs to be installed on the wall. Drainage branch pipes also have two ways: concealed installation and exposed installation. When hidden, there is a certain height difference between the floor elevation of the bathroom and the floor elevation of the bedroom and living room. After the drainage branch pipe is laid and installed, it shall be filled with stones and painted on the ground. The surface-mounted drainage branch pipe is installed in the ceiling of the lower bathroom and needs a hanger. The concealed installation method is not only beautiful, but also avoids the hidden danger of disputes between upper and lower households in the future. In addition, unlike the water supply pipeline, because the drainage pipeline is not a pressure pipeline, the probability of pipeline damage is very small. This installation method is worth popularizing.

(2) Key points of quality control

The key points of quality control at this stage are: a) the pipeline is firmly installed, and the installation of supports and hangers should meet the specification requirements; B) The insertion depth of the interface must meet the specification requirements to ensure the tightness of the interface; C) The position and elevation of the branch pipe to the water (drainage) point shall strictly meet the design requirements; D) The slope of the drainage branch pipe along the water flow direction should meet the design requirements; E) When installing the valve, the valve should be closed to prevent impurities from entering and affecting the sealing performance of the valve. When installing one-way valve, attention should be paid to the consistency between the inlet and outlet direction of the valve and the direction of water flow.

4, pipeline purging and test stage

After the pipeline installation, various tests should be conducted to check the tightness of the pipeline system, and the pipeline of the water supply system should also be purged to meet the hygiene requirements. The testing contents include: water supply pipeline pressure test, drainage pipeline irrigation test and drainage pipeline ball passing test. If there is any problem in the inspection, it is necessary to find out the reason, make rectification and re-inspection, and only after passing the inspection can it be accepted.

5, equipment and sanitary ware installation stage

The installation of equipment and sanitary ware must be placed at the end of the construction process after pipeline purging and pressure test to protect the finished products and prevent other types of work from damaging the equipment and sanitary ware during operation. At the same time, because the installation equipment and sanitary ware are valuables, they are easy to disassemble and need anti-theft. The installation position of equipment and sanitary ware must be correct, and the installation elevation of washbasin and vegetable basin should meet the design and use requirements, and the installation should be firm.

6, metal pipeline painting and anticorrosion stage

This stage is the final stage of the construction process. Fire water supply pipes must be painted with red lead antirust paint, metal supports and hangers must be galvanized or painted with antirust paint, and when buried water supply pipes are metal pipes, they must be treated with anticorrosion.

(3) Water supply and drainage construction technology and measures in the later stage of construction

After the site construction is basically completed, we should do a good job in the later quality control. Before the completion of the project, all valves, water meters, fire hydrants, sanitary appliances and other facilities should be thoroughly cleaned to ensure that there is no dirt in the box and appliances and the surface is clean. Check the water pressure test of water supply pipeline, the purging of water supply system, the pressure test of valves, the irrigation test of drainage pipeline and the compilation of test reports, and sort out and summarize all kinds of concealed works, all kinds of water supply and drainage technical data, certificates of conformity, quality guarantees, and test reports of all kinds of electrical appliances and materials. , and bind them into a book. According to the actual construction situation of the project, a complete project completion drawing is compiled, sorted and bound into a book, which will be used as the basis for project acceptance and the original data for future maintenance by the construction unit.

Although some small achievements have been made in recent years, there is still a gap compared with the trust and expectation of the company and superior leaders. In the future work, I will work harder, constantly improve my professional and technical level, and better complete the design task. Broaden our thinking, complete our work more creatively, and strive for our ideals.

Annual work summary, a water supply and drainage designer, three minutes passed. It has been almost nine months since he joined the company in March. From being unfamiliar with the company's system, management process and post when I first joined the company, I have made obvious progress in dealing with and using all aspects of the company's water supply and drainage (from the aspects of company system, basic knowledge of water supply and drainage, water supply and drainage process, water supply and drainage equipment, etc.). ), and I have certain judgment and analysis ability. The following is a summary of my work during this period.

First, the basic knowledge learning stage?

Learning of text theory, process route drawings and equipment principles: from domestic water, fire water, circulating water, deaerator, water purification treatment to rainwater collection.

1, the word theory mainly studies the basic terms related to water supply and drainage, grasps the most basic theory, the meaning expressed by units such as liquid level, pressure and flow, and defines relevant figures to reflect problems and how to adjust them. For example, the definition of concentration multiple: the ratio of the substance content of evaporation concentration to the same substance content in the make-up water, and the ratio of the dissolved solid of evaporation concentration to the dissolved solid in the make-up water in circulating cooling water. In actual measurement, we measure this value by the concentration ratio of CL ions in the circulating water system of Silbon. According to different concentration multiples, adjust the opening of the make-up valve and the drain valve. Through the study of these basic knowledge, I can understand the following process more easily, and each index represents a different meaning.

2. The learning of process roadmap is mainly based on drawings, and the route is the most important. Where the pipeline goes every day, what materials are in it, and what changes have taken place in the materials after passing through a piece of equipment are all very important. I can't make any mistakes in my future work, and I won't be given a chance to make mistakes. Therefore, during these months of study, the technological process is the most important. For example, purified water is composed of produced water, clarified and turbidity removed by high-efficiency sedimentation tank, coagulant, flocculant and so on. Is needed; BIOS-treat further removes impurities and other small particles; The intermediate water tank is used as backwashing water to store water; Reverse osmosis and ultrafiltration focus on removing the corrosion of various ions, such as hardness, alkalinity and CL ions. Influence of water pipeline and scaling on heat recovery effect, and then enter larger produced water for other devices.

Through the study of process flow, I have mastered what the main work of our water supply and drainage department is. Understand our future raw materials, media and products. How do we turn unqualified water into qualified water for process use? It also made me understand that my work is very responsible.

3, equipment principle learning, mainly learning the equipment used in the process, the structure, principle and function of these equipment. Through the study of these equipments, we can better understand the function of this kind of equipment in the process route of this day and understand the process more deeply. For example, the structure and working principle of the mechanical clarifier: the clarifier is mainly composed of water collecting basin, supporting bridge, water inlet and outlet pipes, dosing pipe, sampling pipe, sludge discharge pipe, first reaction chamber, first reaction chamber, second reaction chamber, guide plate, sludge stirring slurry, stirring impeller, stirring shaft, sludge scraping shaft, sludge scraping arm and top supporting steel structure. Mechanical stirring clarifier is a combination of mixing chamber and reaction chamber, that is, raw water directly enters the first reaction chamber. Due to the stirring and lifting of stirring blades and turbines, influent, chemicals (PAC coagulant, PAM flocculant) and a large amount of returned sludge quickly contact and mix here. The mechanical reaction is completed in the first reaction chamber, and it collides with raw sludge in the returned sludge again to form larger flocs, which are then lifted to the second reaction chamber by turbines. Then it flows into the clarification area for separation, and the clear water rises and is led out from the water collection tank. Sludge flows back to the first reaction chamber at the lower part of the clarification area, and is scraped to the sludge hopper by a sludge scraper, and the sludge discharge is controlled by the sludge discharge valve at the bottom of the tank, so as to achieve the effect of clarification and separation of raw water.

Second, the internship stage.

/kloc-I started my internship in Honggang Petrochemical Company in October and February. Although the time is only one month, and I have to work shifts, I think I have learned and really understood the petrochemical enterprises and factories.

1, on-site physics learning.

2. During my internship, I saw the circulating water tower that I had drawn many times on the drawings, the circulating water pump that was twice as high as me, and the pipeline that freely entered and exited one meter and two meters. All these make me deeply aware that my work is extremely important and dangerous. At the same time, I also saw the internal structure of the equipment, which is more obviously different from the drawings, and recognized the actual working state of the equipment. Many unclear places on the drawings have been solved, but at the same time, other problems have arisen, such as what is the best state of the equipment, the winding direction of the pipeline, how to remember the materials in these pipelines, the collective parameters of the materials, and what to do when the equipment needs backwashing or maintenance.

2. Studying in the central control room

I think this is extremely important. The biggest feeling is that as long as you are here, you can clearly understand that those big guys outside are completely connected as a whole, a system, a set of technologies and a factory. The changes of various materials in the pipeline are very obvious. Your control needs to be very precise. Every instrument and valve reflects the running state of the whole system, so this is the most important position of the whole system. Seeing that the master in Honggang is always busy, I also hope that I can operate every valve as carefully as the master, record every data and complete every job.

Third, the experience in the process of work

1, accumulate experience and apply what you have learned. In the course of nine months' study, I not only learned a lot of professional skills, but also applied what I have learned to my work flexibly. Only by using professional knowledge and thinking actively can we find accurate results when solving analytical problems.

2. Ask for advice with an open mind and strive for self-improvement. In the process of learning, learn from other colleagues with an open mind, learn from good working methods, unite and cooperate, and enhance the sense of responsibility, so that what you have learned can only be used in future work, without wasting the company's resources, and improve the quality and standard of completed work. Continue to cultivate their sense of responsibility and dedication, work hard and make more contributions to Sri Lanka.

In short, in the past work, as an operator who is not on duty, I have been studying hard, trying to be a man and doing all the work assigned to me by the leader. In the future work, with the gradual and comprehensive construction of various projects, I will, as always, study harder and complete all the work harder. I believe that through my future work, I will make greater efforts for the development and growth of Sibang Company. And wish Sri Lanka a more brilliant tomorrow.
