Scope of application

1. Plastic inspection wells for drainage in building communities are suitable for the design, construction and maintenance of plastic drainage inspection well projects within building communities (residential areas, public building areas, factory areas, etc.) with a buried depth of no more than 6m and no down-well operations.

2. Construction of plastic drainage inspection wells under general soil conditions, soft soil, permanently frozen soil, seasonally frozen soil, expansive soil and collapsible loess soil conditions.

3. Areas with seismic fortification intensity of 9 degrees and below.

4. The ground load of the general driveway in the residential area is designed based on the total weight of the vehicle of 15t (5t under the rear wheel pressure); the ground load of the fire truck is designed based on the total weight of the vehicle of 30t (6t under the rear wheel pressure).

constitute

It consists of a well base, a well shaft, a well cover or a load-bearing cover ring and accessories.

HDPE spiral pipe is generally used in inspection well shafts.

Inspection well covers are generally made of resin.
