Outdoor water supply and drainage

Outdoor water supply and drainage refers to the drainage system outside the building, including rainwater drainage and wastewater drainage. It is an important part of the building, which directly affects the service life and environmental sanitation of the building. Therefore, the design, construction and maintenance of outdoor water supply and drainage are very important.

A, outdoor water supply and drainage design

The design of outdoor water supply and drainage is very critical, and many factors need to be considered, including the structure of the building, the surrounding environment, water displacement, drainage methods and so on. The following are the steps of outdoor water supply and drainage design:

1. Understand the structure and surrounding environment of the building, including topography, landforms, climate, etc.

2. Determine the type and quantity of drainage equipment according to the use and displacement of the building.

3. Determine the drainage mode of the drainage system, including gravity drainage and pressure drainage.

4. Design the pipeline layout and construction scheme of the drainage system.

5. Carry out construction and installation according to the design scheme of drainage system.

Second, the outdoor water supply and drainage construction

Outdoor water supply and drainage construction is the key to the normal operation of outdoor water supply and drainage system. The following are the steps of outdoor water supply and drainage construction:

1. Prepare for construction according to the design scheme, including the procurement of materials and the deployment of construction personnel.

2. Carry out ground excavation and pipeline laying.

3. Conduct pipe connection and sealing treatment.

4. Install and debug drainage equipment.

5. Testing and acceptance of drainage system.

Third, outdoor water supply and drainage maintenance

Maintenance of outdoor water supply and drainage can prolong its service life and ensure its normal operation. The following are the steps of outdoor water supply and drainage maintenance:

1. Clean the drainage pipeline regularly to prevent pipeline blockage.

2. Regularly check the operation of drainage equipment, timely maintenance and replacement.

3. Regularly clean the drainage ditch and rainwater outlet to keep the drainage unblocked.

4. Regularly check the sealing condition of the drainage system, and timely repair the leaking point.

5. Check and maintain the drainage system regularly.
