预制混凝土检查井各构件之间采用企口连接，以提高整体稳定性和严密性。预制钢筋混凝土装配式雨、污水检查井为同一井型，雨、污水检查井井筒高度，可通过多节预制构件组合调节。预制混凝土检查井井壁踏步、井壁开孔或预留管口的尺寸、位置和数量以及吊环或吊装孔位置可由设计确定。
In order to improve the overall stability and tightness, the prefabricated concrete inspection well is connected by notches. Prefabricated reinforced concrete rainwater and sewage inspection wells are of the same well type, and the height of rainwater and sewage inspection wells can be adjusted through the combination of multiple prefabricated components. The size, position and quantity of prefabricated concrete inspection well wall steps, well wall openings or reserved pipe orifices as well as the location of lifting rings or lifting holes can be determined by the design
