Double-wall corrugated pipe is a new type of lightweight pipe made of high-density polyethylene. It has the characteristics of light weight, high pressure resistance, good toughness, fast construction and long life, etc. Its excellent wall structure design greatly reduces the cost compared with pipes of other structures. And because the connection is convenient and reliable, it has been widely used at home and abroad. Lots of replacement concrete pipe and cast iron pipe.

2.The axillary corner within the range of supporting Angle of the designed earth arc foundation of the pipeline must be backfilled with medium coarse sand or gravel soil. The backfilling range shall not be less than the supporting Angle 2α plus 30, and the backfilling compactness shall comply with the provisions of the technical regulations.
4. For the section where the longitudinal uneven settlement of the pipeline may occur due to factors such as pipeline load and ground soil change, the foundation should be reinforced before the pipeline is laid.
Sand pile, stone pile and other composite foundation treatment methods should be adopted for the foundation treatment of polyethylene drainage pipe. Rigid foundation treatment measures such as driven pile, concrete pad and concrete strip foundation shall not be adopted.
