Inspection wells are set up for the maintenance and easy installation of urban underground infrastructure such as power supply, water supply, drainage, sewage, communication, cable TV, gas pipes, and streetlight lines. Generally located at pipeline intersections, bends, changes in pipe diameter or slope, and at regular intervals on straight pipe sections, it is convenient for regular inspection of ancillary structures.

Inspection well is a well shaped structure made of plastic injection molded or brick used for regular inspection, cleaning, dredging, or inspection of underground drainage pipes in residential areas (residential areas, public building areas, factory areas, etc.) with an outer diameter of no more than 800mm and a burial depth of no more than 6m. It is generally located at the intersection, turning points, pipe diameter or slope changes, and water drops of drainage pipes.
Plastic integrated injection molding inspection well refers to the main part of the well seat that constitutes the inspection well, which is injection molded in one go. The wellbore socket adopts a 360 degree circular bearing platform, and the bottom of the well body and seat adopts mesh reinforcement ribs. Each socket adopts a circular reinforcement rib design. According to the number and angle of takeover, there are starting well seats, straight through well seats, 45 degree elbow well seats, three-way well seats, four-way well seats, etc. In order to adapt to various drainage conditions, plastic inspection wells are equipped with plastic integrated injection molded accessories such as variable diameter joints, confluence joints, and multi joint shafts. To ensure the smoothness and sealing of the entire drainage system.
