How to design drainage inspection wells, The drainage well is mainly made of polymer resin as processing material, which replaces the traditional red brick cement material, effectively curbing the use of red brick cement material, thus saving the surface soil resources; The common specifications of drainage wells for building communities are 315 mm and 450 mm in diameter, which changes the application practice that the traditional inspection wells are limited by the manufacturing method and the diameter is more than 700 mm, thus greatly saving the land space occupied by the buried inspection wells. How to design drainage inspection well?

1. Design angle of overall scheme of drainage inspection well

The application area of drainage inspection wells shall be divided, and the green belts, buildings, public facilities, pedestrian passages, vehicle passages, etc. in the surrounding environment of the design area shall be marked. The plastic inspection wells and drainage pipes shall be clearly planned on the whole design drawing, and the legend shall be made; In addition, it is necessary to specify the diameter parameters and slope parameter control standards corresponding to the drainage pipeline in the overall design sketch map.

2. Applicable scope of drainage pipeline

Some communities have high requirements on the environmental impact and functional performance of drainage inspection wells. For example, under the ground of some frozen layers, drainage inspection wells are required to be resistant to low temperature; Some high-temperature workshops need drainage pipes to withstand high temperature; There are also more requirements for chemical areas, such as corrosion resistance and leakage prevention.

3. Design specification for use of drainage inspection well

At present, plastic drainage inspection wells mainly include starting wells, one through wells, straight through wells, 90 degree elbow wells, three through wells, four through wells and other types. In the design process, it is necessary to distinguish what kind of inspection wells should be used in that place.

4. Drainage inspection well pipeline layout

The diameter and elevation of the drainage pipe corresponding to the plastic inspection well and the pipe invert shall be clearly marked in the corresponding floor plan design sketch map; Secondly, for domestic sewage and waste water, the basic principle of keeping vertical correspondence between pipes and external walls should be followed in the process of designing and arranging corresponding discharge pipes. If there are multiple discharge pipes connected to the same plastic manhole in actual work, the layout design scheme of each discharge pipe should be kept relatively parallel.

5. Pipe selection

Try to ensure the quality, safety and reliability of drainage pipes in later use. It is recommended to use more buried pipe materials, The selection of connection socket type of well seat shall be designed in combination with the corresponding outer diameter parameters of buried pipeline.
