Description

technical field

[0001] The invention relates to the application of a finished plastic inspection well in an outdoor drainage system. Background technique

[0002] The construction speed of existing inspection wells is slow, which has a great impact on the environment and urban traffic, and does not meet the requirements of civilized and rapid construction. The quality stability is poor, and the brick masonry has low strength, especially at the joint between the plastic pipe and the inspection well, which is easy to leak. A research report in Shanghai shows that the cause of the pipeline collapse in the quicksand area is firstly the leakage of the interface, and the second is the damage of the inspection well. Contents of the invention

[0003] The object of the present invention is to provide an application of a finished plastic inspection well with convenient construction and good construction quality in an outdoor drainage system.
