(1) The main foreign standards for plastic inspection wells include. American Materials Testing Standard - "Standard Specification for the Design of High-Density Polyethylene Inspection Wells for Subsurface Applications."
British Standard - "Standard for Plastic Inspection Wells for Drainage and Sewerage Pipes".
Japanese Standard─Japanese Standard "Recycled Plastic Inspection Manholes and Manhole Covers for Rainwater", Japanese Sewerage Association Standards "Hard Polyethylene Inspection Manholes and Manhole Covers for Sewers" and "Hard Polyethylene Small Inspection Manholes for Sewers
》.
European Standard - "Specifications for Manholes and Inspection Wells in Traffic Areas and Deeply Buried Installations".
Both national standards and Japanese standards are applicable to small wells, and European standards are applicable to small wells and large municipal wells. This standard refers to these foreign standards, but the degree of consistency for plastic inspection wells is non-equivalent and has its own characteristics. , the standard structure conforms to the characteristics of our country's standards.
2) Domestic standards for plastic inspection wells.

The Light Industry Standard of the People's Republic of China "Buried Rigid Polyvinyl Chloride Pipe System".
China National Standard/"Rigid polyvinyl chloride spiral pipe fittings for building drainage".
, China National Standard/"Reinforced Reinforced Pipes for Buried Use".
The inspection well is a circular brick underground structure, mainly composed of cushion, foundation, well shaft, well circle manhole cover and maintenance ladder.
Water inspection well.
The flow channel at the bottom can be made into several forms as shown in the figure according to the role of the inspection well in the system. When constructing the flow channel, a sufficient bending radius should be ensured, the flow channel should be smooth, and the intersection angle at the confluence should not be Less than.
During construction, the inner wall of the well is required to be jointed. When the groundwater level is high, the inner wall of the well should be plastered to a position above the groundwater level.
Manhole covers placed on main roads should use heavy-duty anti-theft cast iron manhole covers. The elevation of the manhole covers should match the vertical layout of the community. Inspection wells in non-passage areas should be higher than the designed ground.
