Embedded pipes are generally used to facilitate urban drainage and the laying of various lines. Generally, drainage pipelines include rainwater and sewage; line pipelines include electricity, communications, gas, street lights, military, etc.

In order to solve this problem conveniently, many cities adopt the method of laying buried pipes. The so-called laying of embedded pipes means laying embedded pipes from the main pipe until they are laid outside the road red line and within the scope of land acquisition. The purpose is to use these embedded branch pipes to facilitate the laying of drainage and lines and avoid the need for future drainage systems and line connections. Unnecessary road breaking and other problems, because road breaking construction will cause a lot of troubles, such as affecting traffic, disturbing the existing pipelines on the road, etc.
