Install socket must be clean, aprons, etc. Traditional pipe installation of pipe trench excavation requirements can only put the pipe in the trench and for sealing can, in the absence of loose soil, the original can not pressure ramming cushion layer.

PVC pipe fitting, as a new type of non-metallic pipe, use the existing metal pipeline detection equipment, can't detect its location, but if the pipeline buried on the pipe during the construction of embedding a wire can be easily solve the problem.
