Summary of Tunnel Engineering in 2023 1

I have worked in the company for almost a year. During my tenure, I am very grateful to the company leaders, especially General Manager Li, General Manager Han and colleagues for their support and help. I also quickly integrated into our collective and became a member of this big family. I am very glad that with the care of leaders and the help of colleagues, I came to the warm department of Hang Seng in Shandong Federation and felt this collective atmosphere. I learned a lot and grew a lot when I came to the company. I am even more grateful to the leaders for their esteem and care. In the future, I will be strict with myself and do my job well.

All these have enhanced my awareness of coordinating my work. In the past year, I tried my best to satisfy the company and leaders. However, some mistakes occurred in the work, which also caused losses to the company. I apologize to the company and the leaders. I know I have many shortcomings and deficiencies, and I am improving myself bit by bit.

I. Monthly work arrangement and sales statistics of sales managers in various provinces and regions:

This kind of report can be said to be easy for me. But while filling in the data and content, I have always been cautious. We all know that this report is a powerful basis for provincial sales managers to prove their business level to leaders. Once the data and content are wrong, it will bring negative influence to the provincial sales manager and bring unnecessary trouble to the company. Therefore, it must be timely and accurate, so that the company leaders can formulate corresponding countermeasures according to this table for different regions, thus controlling risks.

Second, the office daily work summary:

As the sales office of the Ministry of State, I know the importance of the post. The sales office is an important link between the preceding and the following, which requires communication, coordination and contact in all directions. , to ensure that the sales staff. In more than a year, I have been exposed to various jobs in the sales office. These tasks also require a high degree of patience and care. Prepare delivery materials (color pages, samples, etc.). ), provide documents needed by customers, organize sales forms and so on. In the face of all kinds of daily affairs, we should finish what we started, and make arrangements to follow up (such as following up the express delivery in time, checking the website when we have time, and asking customers whether the goods have been received).

I can also enhance my personal communication skills while working. The sales office is a connecting link between the preceding and the following, communicating inside and outside, coordinating the left and right, grasping the latest changes in the market, and doing all the rear protection for the business manager. We should also strengthen our awareness of self-coordination when dealing with the tedious daily affairs such as the first camp materials, agency agreements, publicity color pages and samples. After a year of hard work, we have basically achieved everything, and everything has an echo. And learned to make a work plan. Orderly, powerful and effective

Third, the direction of future efforts:

Over the past year, in the spirit of love and dedication, although progress has been made, there are still some problems and shortcomings. If the goods are not tracked in time during the delivery process, the goods will arrive at the customers later. The tracking work is not perfect; In the future, I will learn a lesson and work hard in the following three directions:

First, strengthen self-study, expand knowledge, study medical professional knowledge hard, and be aware of the development and overall planning of the same industry;

Second, all parties should seek truth from facts, draw inferences from others, and be good assistants to leaders.

Third, be attentive, careful, patient and open-minded.

In the future work, I will foster strengths and avoid weaknesses, become a well-known sales office, and grow together with the enterprise.

Summary of Tunnel Engineering in 2023 II

We should be innovative, integrate knowledge, ability and wisdom in practice, improve our comprehensive quality and ability, and lay a good foundation for the success of our cause. Thank the internship unit for providing me with this internship opportunity! Thanks to the company's deputy director, supervision engineer, measurement engineer and laboratory director for their teaching and training! Thank you for your help!

1, site practice harvest. I learned a lot during my production practice. I have personally visited all aspects of tunnel construction and learned the construction technology and technology of the tunnel.

2. Learn to build important projects. The whole concrete structure engineering includes earthwork, reinforcement engineering, formwork engineering and concrete engineering. The following will summarize the knowledge I learned during my internship and the projects I participated in:

2. 1 earthwork excavation. Because the quality of surrounding rock directly determines the supporting parameters, and it is also the first key project of earthwork, it is very important to do a good job of excavation. When earthwork is excavated, under-excavation will affect the thickness of support, while over-excavation will easily produce cavities, which will also affect the stability of surrounding rock.

2, 2 understand the reinforcement engineering. Steel bar is the skeleton of reinforced concrete structure, and it is integrated with concrete through the binding force. Reinforcement engineering is one of the three major projects of concrete structure engineering.

Reinforcement in reinforced concrete structures, such as compression reinforcement, tension reinforcement, vertical reinforcement, distribution reinforcement and stirrup, can be divided into the following types according to their functions in the structure:

1, stress bar-steel bar bearing tensile stress and compressive stress.

2. Stirrup-it bears a part of diagonal tensile stress and fixes the position of the stressed steel bars, and is mostly used to connect two rows of steel bars in the lining.

3. Vertical bar installation-used to fix the position of steel hoop in the beam and form the steel skeleton in the beam.

4. Distribution bar-used to be arranged vertically with the stressed steel bars of the plate, to transfer the bearing weight to the stressed steel bars evenly, to fix the position of the stressed steel bars, and to resist the temperature deformation caused by thermal expansion and contraction.

5. Others-structural members configured due to structural requirements of members or construction and installation needs. Such as waist tendons, embedded anchor bars and rings. At present, the commonly used steel bars are hot rolled round steel (commonly known as round steel), hot rolled ribbed steel bar (commonly known as rebar), cold rolled twisted steel bar and cold drawn low carbon steel wire. Among them, the first two are the most widely used, and the latter two are generally used in high-strength concrete. Round steel is identified as hpb235, and the commonly used diameters are 6, 5, 8, 10 and 12. Thick steel bars are not often used, but 6, 5 and 8 are most commonly used, and are generally used as stirrups. 8. 10 and 12 are generally used as distribution bars. The common logo of reinforcement is hrb335, and the commonly used diameters are 12, 14, 18, 20, 22, 25 and 2. Coarse steel bars generally appear in mass concrete projects, which are not commonly used, but generally less than 25. Because it is difficult to check the quality of steel bars after concrete pouring, the steel bar project is a concealed project, which needs to be strictly checked in the construction process and the necessary inspection and acceptance system should be established. In order to ensure the normal work of concrete structure in the use stage, the specifications and positions of steel bars must be consistent with the structural construction drawings during the construction of steel bars. In engineering, due to insufficient length or the requirements of construction technology, steel bars are often connected. Therefore, the connection of reinforcement is an important link in reinforcement engineering.

2, 3 understand the template engineering. Formwork engineering of concrete structure is a very important part of concrete forming construction. The formwork we are talking about actually includes two parts, one is the formwork that forms the shape and design size of concrete members, and the other is the supporting system that ensures the shape, size and spatial position of the formwork. The formwork shall have certain strength and rigidity to ensure that the concrete will not be damaged or deformed under the action of self-weight, construction load and concrete lateral pressure. The supporting system should not only ensure the accuracy of the spatial position of the formwork, but also bear the self-weight and construction load of the formwork and concrete, so it should also have sufficient strength, stiffness and stability to ensure that it will not sink, deform or destroy under the upper load.

The materials and types of templates are also very different. Generally, it can be divided into wood mold, steel mold and plywood. Most of this project adopts steel formwork, which is not easy to deform. The role of formwork is that in the process of structural construction, the concrete that has just been stirred from the mixer is in liquid state, and it needs to be poured into the same model with the shape and size of the component, and the required structural component can be formed after the concrete is solidified and hardened. Formwork is a model used to form reinforced concrete structures or members.

Formwork support system is a temporary structure to ensure the shape and position of formwork panel and bear the dead weight of formwork, steel bar and fresh concrete and construction load. The vertical support of formwork mainly includes pipe supports assembled in dispersion, steel columns with height adjustable devices and portal frames that can be used independently. Before installing the template, the template needs to be designed and calculated. Generally, it is not necessary to design or check the commonly used structural types within its scope of application. Generally speaking, experienced contractors and workers know how to install them. However, some special structures, new system templates or general templates beyond the scope of application need to be designed or checked. For example, the brim of the tunnel mouth. Otherwise, it is easy to swell.

20xx is about to say goodbye. Recalling the busyness and harvest of this year makes me happy and sad. I have been doing quality inspection in the injection molding workshop for more than 3 years, and the post does have some work pressure, but for me, no pressure means no motivation. As a quality inspector, in order to make myself grow faster and improve my work, I made the following work summary:

First, check the quality of work.

As a quality inspector, we should not only master professional testing knowledge, but also carefully find problems, find problems and solve them. So this year's on-site quality work has benefited me a lot. Before inspection, you should learn to read the product drawings and try the products. According to the requirements of quality process, do a good job of supervision, find and correct the problems existing in the inspection process. Cooperate with operators to conduct a comprehensive inspection of product quality, and put forward and correct the problems existing in the product in time. Track and check the process of special products to ensure that each process is qualified. Strictly control the quality of purchased products, and summarize and analyze the results afterwards, so as to facilitate the continuous improvement of the work. Before coming off work every day, do a good job of handing over the quality problems in the inspection process. Record the merits and demerits of the problems that are easy to appear in the future inspection process, and constantly improve the level of personal professional inspection; Seriously reflect the quality problems existing in the site and the problems that need to be solved by the company.

Second, the shortcomings and problems in the work

1, there is still a certain gap in product quality requirements, which leads to the phenomenon of small batch return. On the one hand, due to the lack of detailed personal inspection and sufficient professional knowledge, on the other hand, under the condition of heavy workload and long time, the work efficiency is not high.

2, in the discovery of quality problems, not sure whether decisive, in dealing with some things need the help of leaders.

3. Due to the shortage of quality inspectors, long working hours and increased workload, one person asks for leave and no substitute is available.

Three. Work plan and improvement for next year

1, I will further develop my advantages, improve my shortcomings and do my best to do my job well. We should maintain a good mental state and carry forward the spirit of hard work, advancing despite difficulties, striving for perfection, being rigorous and meticulous, learning and enterprising, and daring to struggle. Clear up work ideas and improve work efficiency.

2. Before the inspection, I must first know the products that need to be inspected. Before the inspection, I must make preparations in advance and carefully supervise the inspection.

Finally, for humanized management, our company pays attention to the cultivation of employees' skills, team spirit and positive work enthusiasm. I believe I will grow up in the development of your big family, and we will grow up!

Summary of Tunnel Engineering in 2023 5

Spring goes to winter, and cold and heat change. In a blink of an eye, 20 years have quietly ended, and we will enter a new year. Looking back on 2020, under the correct leadership of the company's leaders, all the staff of our quality department worked hard to overcome various difficulties and ensure the certification and subsequent development of the food safety management system. Over the past year, the quality department has made progress in a difficult situation.

I. Review of Main Work of Quality Department in 2020

2020 is a very extraordinary year for the company, an unforgettable year and the most arduous and arduous year for the quality department. Under the correct leadership of the company, all the staff of the Quality Department focused on the food safety management system certification and product quality, vigorously built the food safety management system, actively and conscientiously performed the duties of the food safety management system, and strived to improve the supervision and technical service capabilities, which played an irreplaceable role in the food safety management system certification and production quality management system construction.

Second, the current problems in the quality department

The quality management department is the core department of the company, and the food safety management system gives it an independent quality veto power, which is in a very important position in the operation of the quality management system. Due to many objective factors, it has affected the full play of its functions. The overall performance is as follows:

(a) Institutional reform and capacity-building are at the initial stage of development and improvement.

The company has just passed the certification of food safety management system, but it is still a long-term and arduous task in the future to truly update the old concepts of traditional management, accept and understand and firmly establish the new concepts of food safety management system, because the standardization and procedures of work need employees to complete voluntarily on the one hand, and the constraints of external management system on the other hand to regulate their behavior. At present, there is still a big gap in quality supervision ability, technical service level and R&D innovation ability compared with the same industry, and institutional mechanism reform and capacity building are in the initial stage of continuous exploration and improvement.

(b) The whole quota management is weak and lacks vitality.

Quality management is an important part of the company's management activities, and the supervision responsibility is great. It is the key department for the company to give full play to its functions and technical support. However, the responsibility assumed is not equal to the power given, and the management mode of emphasizing obligations over rights has obviously affected the work efficiency.

(3) The overall quality of personnel needs to be further improved.

The company puts forward higher requirements for inspectors' operating skills and comprehensive quality, and our inspectors need to further improve their operating skills and their own quality. Employees lack actual combat experience, poor ability to judge, analyze and solve problems independently in the process of production quality management, and lack of work innovation ability.

(D) Independent performance of the quality veto is not in place.

The company does not give enough support to the supervision of the quality management department, and occasionally only considers the immediate economic interests of the company and abandons the quality principle, which makes the daily supervision of the quality management department flawed and a mere formality.

Three. 202 1 key work

(A) improve the quality of quality management personnel

First, establish a regular learning and training mechanism to improve the quality of inspectors; Second, continue to stabilize the quality inspector team, so that it can strictly control the quality of products and materials, prevent unqualified materials from being put into production and unqualified intermediate products from flowing into the next working procedure, and prevent unqualified products from being sold out of the factory.

(2) Strengthen supervision and management.

In strict accordance with the provisions of the Food Safety Management Law and the good manufacturing practice, strengthen daily supervision and inspection in the production process, urge and supervise the organization of production in strict accordance with the requirements of the food safety management system, strengthen quality control in all aspects of procurement, production, inspection and sales, and implement quality management to ensure product quality.

(3) Adhere to gmp training to play a role in improving the management level of the company and improving the quality of employees.

The mission of quality management is related to honor and responsibility. With the correct leadership of the company and the joint efforts of all employees, let's further cheer up, unite as one, ensure product quality with a better mental state, a more solid and meticulous work style and faster work efficiency, and play a greater role in ensuring product quality and safety and promoting the company's entrepreneurship and make new contributions.

Summary of Tunnel Engineering in 2023 6

June this year is the thirteenth national "Safe Production Month". According to the implementation plan of the management office, all the staff of our hospital adhere to the policy of "safety first, prevention first and comprehensive treatment", and actively participate in the work of safety production with practical actions around the theme of "scientific development and safe development", and strive to eliminate hidden dangers of accidents. In order to ensure the safety and smoothness of the tunnel, remarkable results have been achieved. The activities of 20xx Safety Production Month are summarized as follows:

First, strengthen organization and leadership to ensure the implementation of various activities in the month of safe production.

According to the spirit of the activity document of "Safe Production Month" at higher level, our hospital established the leading group of "Safe Production Month" with Xu Jixian as the leader and Zheng, Lang, Gong Xiaojun, Xu Rong as members. On the morning of June 1, our hospital held a mobilization meeting for "Safety Production Month", which conveyed the spirit of the document "Notice on Printing and Distributing the Implementation Plan of" Safety Production Month "in xxxxx Office", formulated the implementation plan of "Safety Production Month" in our hospital, defined the responsibilities and tasks of each post and team, and made specific arrangements and arrangements for the next "Safety Production Month" work in our hospital. Ensure the smooth development of safety production month activities.

Second, strengthen safety publicity and enhance the safety awareness of all staff.

In this year's "Safety Production Month" activities, I carried out various safety culture publicity activities, organized activities in a form that employees loved, and achieved effective and wide-ranging results. In June, safety signs 1 were hung in the carport, safety culture banners 1 were hung in the lobby, 5 safety posters were posted in the courtyard, more than 30 safety signs were posted in the tunnel, and the first-phase safety bulletin board was made, which created a good safety production atmosphere.

Our hospital also carried out the rationalization proposal activity of "I speak for safety", and mobilized all the staff of our hospital to put forward rationalization suggestions from the aspects of safety management innovation, safety education, safety facilities and safety technical measures. Activity * * * Received 10 rationalization suggestions and adopted 3 suggestions.

Two, to carry out various forms of safety education and training activities

1, the institute organized all teams and groups to study the Operation Manual for Expressway Operation Safety of Group Company and the Operation Rules for Safety Management of Road-related Maintenance Operation of Directly Administered Plate (Trial) from June 7th to June 7th every afternoon 16: 00 to 16: 30.

2. Organize employees to learn safety production laws and regulations such as Safety Production Law, Road Traffic Safety Law and Fire Protection Law. , and studied the "Regulations on Electric Safety Work" and "Company Rules and Regulations". On June 15, all employees took the safety knowledge examination, and the qualified rate was 100%.

3. Organize various safety trainings. Our hospital has carried out the study activities of case analysis of typical safety accidents. Through the study of typical cases, we analyzed the reasons and learned lessons, which improved the safety awareness and self-protection ability of employees. We also organized staff to train the electric shock personnel in cardiopulmonary resuscitation (CPR), so that all plumbers can master this method and ensure effective rescue in case of electric shock.

Third, carry out emergency drills.

On June 19, the plumber, monitor and part-time safety officer were organized to conduct a desktop exercise of the "Three Preventions" part of the emergency plan of the hydropower class, mainly to simulate the general collapse of the tunnel slope during heavy rainfall, which affected the traffic of the main lane, so that the plumber, monitor and office staff could simulate the disposal measures and process. Through this exercise, the ability to deal with three-prevention accidents has been effectively improved.

On June 2 1 day, the plumber, supervisor and office staff were organized to drill the tunnel fire emergency plan in the first emergency parking area of xx tunnel in Huang Xiang. The drill mainly simulates the disposal process of general cargo burning caused by vehicle tire fire in the tunnel. During the drill, the fire of trucks and vehicles is simulated first, the supervisor completes the report and changes the information, and the plumber gives an early warning. Then use dry powder fire extinguishers to put out vehicle fires, and use fire hydrants, fire hoses and foam extinguisher in tunnels to put out general cargo fires. Through this drill, employees are more proficient in the handling process of tunnel fire accidents, and also master the use of main fire-fighting equipment and facilities in the tunnel. Let plumbers and supervisors cooperate more tacitly when dealing with special events in tunnels.

Four, take the opportunity of safe production month, vigorously carry out safety inspection and hidden dangers rectification work.

On June 25th, a safety inspection was organized with the participation of the person in charge, the management personnel and the monitor. During this inspection, some potential safety hazards were found, such as: someone in the tunnel was seriously damaged, and the emergency lighting in the People's Tunnel was burnt out. The first potential hazard has been reported to the Equipment Department for coordination and solution. The equipment department replied that it would arrange personnel to come and replace the damaged door in the near future. Now, as soon as the new person is made, he is ready to replace it. The second hidden danger was immediately replaced by personnel. At the same time, we also checked the standardization construction activities carried out by hydropower class and monitoring class in the safety team. Each team can carry out related activities according to the standardized construction plan of the safety team and institute, and establish relevant accounting records.

Five, to carry out other safety production activities.

On June 10, the staff of the institute was organized to go to the main toll station to distribute the publicity manual on tunnel safety driving, reminding drivers and passengers in the past to pay attention to traffic safety in the tunnel and guiding them to correctly use various fire-fighting equipment in the tunnel. On June 14, we went to the main toll station to carry out a summer activity in hot summer, and distributed mineral water, ten drops of water, cool oil and other heatstroke prevention and cooling items to the drivers and passengers. Through the activity of "enjoying the cool", drivers passing by were prevented from driving, which further ensured the safety and smoothness of the road section.

Through the development of this activity, we have received good results, improved employees' awareness of the importance of safety production, and enhanced the safety awareness and safety responsibility of all employees. Safety production is a matter of life, and safety is no small matter. The awareness that safety responsibility is more important than Mount Tai has gradually become people's common sense, which has obviously enhanced our awareness of considering safety issues in our work, further implemented various safety measures, and laid a solid foundation for better safety management in the future.
