The box culvert foundation of this project adopts natural foundation, and some parts adopt dynamic compaction earthwork, dynamic compaction block stone pier and replacement block stone as the bearing layer of box culvert foundation. After treatment, the standard values of bearing capacity are all greater than 200KPa, which meets the design requirements. In this project, two methods, plate load test and Rayleigh wave test, are used to detect the foundation treatment. See Test Report of Foundation Soil Load Test and Rayleigh Wave Test Report for the test results.

The topographic unit of this project is complex, including soft foundation treatment and high excavation area, which has great influence on the construction period and quality control. Therefore, our company has formulated a rigorous and reasonable construction schedule, construction technology, construction process and quality assurance technical measures, and put them in place. The tight construction period is the biggest obstacle to the development of this project, only 90 days. We should not only consider the intermittent time of soft foundation treatment, but also consider the coordination and balance with the site leveling project to avoid unnecessary repetitive processes or cause construction interruption and mechanical shutdown. Through the coordination and guidance of the leaders of the owner, supervisor, design institute and other units and engineers, the foundation treatment and earthwork construction of this project can basically proceed smoothly, ensuring the continuity of construction and creating favorable conditions for the main structure construction of box culvert in the future.

Second, the construction management and organization

Due to the tight construction period of this project and the large amount of earthwork excavation and filling, it takes some time to complete the soft foundation treatment, and the task is heavy. In order to ensure the efficient, high-quality and safe completion of this project, our company has invested a lot of manpower and material resources in the construction of this project, and established a project management department with the corporate legal representative as the leader and the project manager as the core. The project department and the following departments are United to overcome difficulties and stick to it? Survival by quality, development by reputation, and efficiency by speed? With the full support of the owner, supervisor, design institute and other units, we will devote ourselves to the construction of this project.

Summary of project management: Time flies, and the sun and the moon fly like flies. One year is really short, and before you know it, 20 15 will pass. The new year has come again. At the turn of the old and the new, sum up the past, think about the future, learn from the past, make up for the future and be honest with yourself.

Summary of work, in order to better complete their work in the new year.

I joined the engineering department of the company from March 2065438 to March 2005, and was mainly responsible for the technology, construction and cost management of HVAC and water supply and drainage. In the course of my work, I will abide by the company's rules and regulations, be strict with myself at ordinary times, and be honest and self-disciplined. I am conscientious and responsible in my work, able to integrate theory with practice, cooperate with colleagues in the engineering department and related departments, and better complete all the work assigned by the company leaders.

First of all, in terms of technical management:

1, can patiently and meticulously do a good job of drawing review, cooperate with the competent leaders and relevant design units to implement the location and direction of water supply and drainage, heating, gas and other pipe networks in the community, find unreasonable schemes and designs as much as possible, put forward their own schemes and ideas, actively communicate with designers, and improve the design of schemes and construction drawings.

For example, Zhongrong International Project has many underground structures, and the underground garage and underground civil air defense are connected with various buildings, which will lead to drainage pipes in the future. Therefore, it is proposed to the competent leaders that a passage should be set aside between buildings 2#, 3#, 4# and 5# and underground garage and underground civil air defense, otherwise the drainage pipe network in the community will not be laid. For another example, the design institute designed the heating and water supply and drainage pipes of the connector on the street of Hankou, but there was no place to lay so many pipes on the street of Hankou. After consulting the competent leader, raise an objection to the design unit in time, and change the design after being audited by the design unit.

2. External coordination: For an engineering project, external coordination is very helpful for the smooth development of the project. My main job is to cooperate with various professional companies (tap water, heating, gas) to complete the supporting design of the pipe network of the project under the guidance of the competent leader. With the correct leadership and help of the leaders, we have maintained a good cooperative relationship with various professional companies, and the supporting design of various professional pipe networks is proceeding as scheduled. At present, the design of water supply and drainage pipe network has been completed, and the design of gas and heating pipe network is under way. In the process of work, I can actively cooperate with various professional designers to complete various tasks from the company's interests and perspectives.

Secondly, in terms of site management: since I entered the site in April, I began to study the site water use scheme with my leaders, and assisted them to complete the relevant procedures and design work after the scheme was implemented. In cooperation with the water supply company, the construction of temporary water and on-site construction water for Zhongbaiyi Reservoir was completed, ensuring that the project started as scheduled. Before foundation excavation, with the help of leaders and colleagues, the laying of drainage pipes in the construction site was completed according to the actual situation, which solved the drainage problem of foundation excavation in various construction units.

In the process of making the scheme, the plastic drainage pipe is adopted in combination with the actual project. After drainage, the pipeline can also be used for the hole of the range hood, saving some funds for the company. After the project entered the main construction stage, in view of the hidden parts that are prone to problems, the supervisor and the plumbing squad leaders of various construction units were organized to hold a meeting in time, which put forward clear requirements for waterproof casing's materials and production, and made technical disclosure on the problems that are prone to occur in the project. All construction units are required to do a good job in the sample room before the construction of each working procedure, and can continue the construction only after passing the inspection by Party A and the supervisor to ensure the engineering quality.

In the process of engineering construction, because the professionals of the supervision company sometimes can't be in place in time, it is necessary to regularly check whether the positions and specifications of various pipelines meet the design and specification requirements, and find and deal with the problems existing in the project as soon as possible, so as not to affect the construction of subsequent projects. For example, improve the elevation of the drainage pipe outside the house and solve the problem that the drainage pipe on one side of Hankou Street is too low. In the process of construction management, we can adhere to the design documents as the basis, in strict accordance with the requirements of construction specifications for inspection.

Thirdly, in the aspect of project cost management, we can strictly review the site construction visa, follow the principle of construction visa, effectively control various factors affecting the project cost, carefully review the list of materials proposed by the construction unit, and correct problems and mistakes in time.

Most importantly, I have done some work in the past year. In the past year, I have made some achievements, but there are also some shortcomings. I sum up my past experience and try to correct the shortcomings in my past work. In my future work, I will be more strict with myself. While doing our job well, we should constantly learn and accumulate, constantly ask questions, constantly solve problems, and constantly improve ourselves to ensure high efficiency and high quality. Dedicated to the development of the company.

I recommend it carefully.
