Friends engaged in the construction industry know little about the construction technology and deployment of rainwater and sewage pipelines, and even have never heard of it. However, these problems are inevitable in building construction or construction. Therefore, Bian Xiao compiled a detailed introduction to the construction deployment and construction technology of rain and sewage pipes for everyone today, hoping that some of the contents mentioned in it can play a certain role in reminding everyone when decorating.

According to the actual situation of this project after the original building is demolished, and is rainwater and sewage outfalls the main import and export of the project? ,? Therefore, from shallow to deep, the construction steps of branch pipe first and then main pipe are adopted for construction.

1. Dig first to clean up the construction waste around the house, and mark the elevation of the rain mouth and the supporting mouth one by one, so as to facilitate the measurement and control during excavation.

2. After the supervisor inspects the site, start excavation, determine the elevation by piling one by one, and control the slope strictly according to the drawing requirements.

3. When laying precast concrete drainage pipes, pave 12cm sand and gravel for tamping according to the drawing requirements, and construct according to the atlas 04S5 16. During manhole inspection, check the rainwater outlet according to the atlas 02S5 15. According to the corresponding requirements of the inspection well, the foundation is made of fine stone concrete 10cm, the masonry is made of Mu 10 clay brick, and the inside and outside of the well are painted with waterproof mortar.

4. In the process of construction, if you encounter underground obstacles and other facilities that need to be moved or changed, you should ask the supervisor and Party A for instructions, and contact the design unit to make correct construction changes before construction.

5. In the process of trench excavation, in case of underground water or soft place at the bottom of foundation trench, this section of pipeline will adopt flexible interface.

6. When a section of pipeline is completed, in order to ensure the construction needs, please ask the supervisor to check and accept the buried pipeline first, backfill it after it is qualified, and use sand and gravel to protect the slope at 180 ". For protection, the pipelines under some roads shall be constructed in strict accordance with the design and Party A's requirements.

7. In case of pipeline crossing on the west side during construction, when the vertical distance requirement is met, the construction shall be carried out as required; If the requirements cannot be met, cross wells shall be adopted or the construction shall be carried out according to the scheme of Party A and the design unit.

8. After the pipeline is buried, conduct irrigation test on the pipeline.

9. The septic tank adopts the horizontal tank biological septic tank made of glass fiber reinforced plastic, and the tank foundation is excavated according to the tank size. The bottom is natural soil, and the bottom is leveled with 10cm yellow sand cushion. If the bottom is groundwater, it needs to be leveled with 10cm fine stone concrete and 20cm rubble foundation, and then paved with 10cm yellow sand cushion, and then the tank body is installed and backfilled in layers to half. Fill the tank with water to stabilize the tank and prevent the tank top from loosening, and then build a connecting well.

10. During the whole construction process, the construction shall be carried out in strict accordance with the design requirements of drawings and relevant specifications, as well as the on-site guidance of Party A and the supervisor, so as to prevent arbitrary excavation and backfilling, so as to avoid potential safety and quality hazards.

I. Material preparation

Before excavation, all materials will enter the construction site and be temporarily stacked in batches at 10 meter. When laying, it will be transported by bumper cars or two excavators.

Second,? Selection of operating machinery

1, choose earth-moving machinery:? Modern 60 excavator.

2, equipped with bulldozers, trolleys, dump trucks, theodolite, level, shovel (sharp and flat)? Building white? Ok,? Tape measure? Double-headed ordinary steel nails and 4-inch steel nails. Should be located in the original building, in the process of excavation encountered obstacles such as the foundation of the original building, it is necessary to adjust other large pickaxes to remove obstacles at any time.

Third,? Construction measures

1. Because this project is located on the original building, and part of it is based on gravel, 500 ××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××

2. After the roads and some obstacles are cleared, cement blocks should be transported to other places in time to meet the needs of site construction.

Fourth, the project acceptance

During trench construction, supervision and project? The head of the department shall inspect and accept the construction quality of each working procedure one by one. Only after passing the inspection can the next working procedure be constructed.

Verb (short for verb)? Trench backfill engineering

After the acceptance by the supervisor and the person in charge of the project department, the trench earthwork shall be backfilled. Before backfilling, the garbage and sundries at the bottom of the ditch or on the ground should be cleaned up and passed the inspection. In order to prevent the center line of the pipeline from shifting or damaging the pipeline, firstly, both sides of the pipeline shall be filled manually from top to bottom until the top of the pipeline is more than 0.5m, without damaging the pipeline. Only use frog rammer to tamp.

Six, safety management measures

This project is an off-site project, and the foundation pit is excavated. Strictly control the site safety protection according to the employee health and safety management manual and documents of our company, set up a safety management leading group on site, and set up a safety officer on site, and the deputy manager in charge of production will be fully responsible? Responsible for safety production and various safety education activities. The Engineering Department shall organize relevant departments to inspect the site regularly and find hidden dangers. Organize personnel in time? Rectification to ensure that no major accidents occur.

Construction sounds simple to outsiders, but it is full of articles for professionals. I believe that after reading this article, you have a general understanding of the construction technology and deployment of rain and sewage pipelines, as long as you apply what you have learned today to the problems encountered in real life. I hope these contents are helpful to everyone!
