>Safe and environmentally friendly, well sealed to prevent leakage. Plastic The material of the inspection well is high-density polyethylene plastic, which is non-toxic and odorless and can be recycled after use. The good sealing can prevent the leakage of rainwater and sewage to prevent groundwater pollution. It is a chemically environmentally friendly building material and is in line with the national environmental protection policies.< br/> ><

>) Uniform settlement and pressure resistance. The pipe and the well seat are flexibly connected, and the clay in the pipe and the well seat moves together, which solves the problem of traditional inspection wells and plastic The uneven settlement problem caused by pipe connections can effectively prevent ground collapse.

>There are differences. The two have certain differences in the design of the well seats. Only by understanding the differences between the two can we use them better.

: > >Rainwater and sewage diversion is a drainage system. The sewage inspection well separates rainwater and sewage, and each is transported in a pipeline for discharge or subsequent disposal. Rainwater can pass through the rainwater pipe The network is directly discharged to the river. After the sewage demand is collected through the sewage pipe network, it is sent to the sewage treatment plant for disposal. After the water quality is qualified, it is discharged into the river. This can prevent the river from being polluted.
