During this process, the position and angle of the drainage pipe connection cannot be accurately connected. In addition, the diameter of the drainage pipe is smaller than the diameter of the inspection well connection point, so the sealing between the drainage pipe and the electrical inspection well cannot be guaranteed after installation.

[0003] For this purpose, we propose an electrical inspection well drain pipe. Utility Model Content
