What should be noted during trenchless construction of power pipes?

2025-12-20
MPP pipes, or MPP power cable protection pipes, are divided into trenched and trenchless (also called jacking/pulling/traction pipes) types, made from modified polypropylene. Featuring high-temperature resistance, external pressure resistance, and excellent electrical insulation, they outperform HDPE in tensile and compressive strength, with a service temperature range of -5℃ to 70℃. Available in DN110-DN250 mm, they include standard (for open-cut or <4m burial trenchless projects) and reinforced (for >4m burial trenchless projects) variants.
Widely used in municipal, telecommunications, power, gas, water supply, and heating projects, they suit urban/rural trenchless HDD cable ducting, sewage/drainage, and industrial wastewater discharge, as well as open-cut installations. Lightweight with smooth inner walls, they enable low-friction hot-melt butt welding (recommended temperature: 220℃).

Design and Precautions for Horizontal Directional Drilling Pilot Hole

Design and Precautions for Horizontal Directional Drilling Pilot Hole

The pilot hole is the first step of construction, and subsequent reaming and pipe pulling operations are carried out on this basis. The quality of the pilot hole, such as the turning radius of the deflecting section, the smoothness of the trajectory curve, and the position of avoiding underground obstacles, directly determines the success or failure of subsequent pipe pulling operations, so the construction of the pilot hole must be done carefully.
