The drainage pipe, sewage pipe, and sewage pipe in the city are rolled by the ground, resulting in changes in the stratum, which will affect the quality of underground pipes. Some pipelines are damaged internally, and some are broken with obvious cracks. Water flows out of the cracks, and even serious pipelines are subject to external pressure, resulting in a large number of holes.

In this case, the inner wall of the trenchless pipeline can be used for repair. There are no good methods and materials to repair in the market. There is a material 304 stainless steel quick lock.
