According to different functions, there are water drop wells, water sealing wells, ventilation wells, sedimentation wells, etc.

The shape of the inspection well is generally circular, and there are square, rectangular, fan-shaped and other shapes at the connection or intersection of large-diameter pipes.

Inspection well body materials include bricks, stones, concrete or reinforced concrete, glass fiber reinforced plastics, plastics, etc. Reinforced concrete prefabrication and polymer concrete prefabrication are often used abroad.
