Municipal Project of North Passage of Shenzhen Large Industrial Zone

Soil and Water Conservation Project Supervision Work Report

1. Overview of the Main Project

Large Industry The District North Passage is located in the north of the large industrial zone and the south of Kengzi Street. It is designed to start from Danzi Avenue and end at Shenzhen-Shantou Expressway. The total length of the road is about 2.7km, and it runs roughly in a north-south direction. The road grade is urban expressway. The main body is a two-way six-lane road, and the ramp is a one-way two-lane road. The project construction area covers an area of ??47.96hm2, and the scope of responsibility covers an area of ??57.96hm2.

2. Overall layout of soil and water conservation measures

According to the water and soil conservation plan of the Shenzhen Water Conservancy Planning and Design Institute for the North Channel Municipal Project, the project's water and soil erosion prevention and control adopts a combination of engineering measures and biology comprehensive measures. Engineering measures are combined with the main engineering structure, mainly using tracing rods to reinforce the slope soil, using explosion-proof nets to reinforce to prevent rockfall and water and soil erosion, and using building materials to build retaining walls, flood drains, intercepting ditches, and drainage ditches (construction During the process, temporary drainage ditches are set up around each site to prevent water loss from directly acting on the exposed land and causing soil erosion. Because the site is large, temporary drainage ditches are especially set up during the construction process, which minimizes the risk of water loss during the construction process. Water and soil erosion; biological measures mainly use forest and grass planting to protect the exposed soil surface. After the project area is completed, it will form better ecological effects and landscape effects. The details include the following:

1. Slope engineering: Use tracing rods and reinforced concrete skeleton beams to form a fixed slope soil structure, and use explosion-proof nets and green hanging nets to spray shrubs and trees on the slope surface. Grass seeds are used for greening, and measures such as setting up intercepting ditches on the top of the slope and drainage ditches at each level of the slope are provided to prevent water from scouring the slope. Considering that a single grass species can easily cause excessive loss of certain nutrients, resulting in poor vegetation survival, this project uses a mixed planting of a variety of shrubs and grass seeds to ensure a balanced soil nutrition and contribute to a long-term ecological balance.

2. Earthwork: Since this project mainly involves earthwork balancing within the site area, and the project area is large, soil and water conservation during the construction process is the key supervision object of this project. During the process of earthwork excavation and filling, temporary drainage settings in the park are ensured. After each plot of land is leveled, temporary drainage ditches are built around the surrounding bricks for orderly drainage. Finally, they are collected in the sedimentation tank and discharged into the municipal drainage after sedimentation. Box culvert.

3. Landscaping project: This project has high greening coverage and a wide greening area. Temporary drainage ditches will be set up during the greening earthwork leveling construction. After the greening construction is basically completed, the temporary drainage ditches will be filled with soil and greening. .

1. Sign a written construction supervision contract with the project legal person;

2. Prepare a project construction supervision plan;

3. Formulate project supervision details according to the project construction progress;

4. Undertake supervision of the project construction phase, and the supervision agency will be stationed at the construction site;

5. Carry out construction supervision in accordance with the construction supervision rules Construction supervision;

6. Participate in the pre-acceptance of project completion and sign construction supervision opinions.

(5) Supervision work methods and measures

1. When the project enters the construction stage, our company will set up a project supervision agency according to the specific conditions of the project and select supervisors with rich experience. Supervision work.

2. Supervisors should keep in close contact with the owner and the construction unit to pay attention to whether the construction status of the project is normal. At the same time, each construction unit is required to designate a contact person.

3. Supervisors should do a good job in on-site supervision and keep supervision diaries and side station records.

4. Convene regular project meetings and regular meetings to coordinate and solve problems that arise during the construction process, promptly inspect the implementation of quality, progress, and investment during the project implementation process, and coordinate the relationship between relevant parties. , to ensure the smooth progress of the project.

5. In case of project changes and visa issues, actively communicate with the owner and designer, adopt flexible contingency measures, and keep original visa records.

6. Manage, archive, send and receive project supervision documents to prepare for handover after completion.

5. Supervision experience and understanding

1. Assist the owner to deal with the relationship with the construction unit. Assist owners to choose construction units with good quality and strength as much as possible, and collaborate to formulate some specific measures for on-site management, such as the "five-person" attendance system, written notification system, penalty regulations, etc., to comprehensively strengthen the management of the construction site.

2. Deeply understand the design intention. It is not only necessary to familiarize yourself with the construction drawings and construct according to the drawings, but also to understand and master the parts that are difficult to deepen in certain design areas according to the project conditions. According to the design intention, the construction unit must be urged to formulate detailed construction plans for specific parts and take practical measures. Effective solutions and strive to achieve the best results.

During the construction supervision of the soil and water conservation project of the North Passage of Shenzhen Industrial Zone, all supervisors acted with an attitude of being responsible to the owners and followed "strict supervision, enthusiastic service, impartiality and meticulousness" in their work. In accordance with the supervision principles, we closely coordinated with supervision, owners, design, construction and other units, worked together, worked conscientiously, and fulfilled the supervision contract with all our best and responsibly.
