re. Metal corrugated pipe is a flexible structure. The corrugated pipe has the excellent characteristics of lateral compensation displacement in the structure, which can give full play to the strong tensile performance and superior deformation performance of steel, and has greater anti-deformation and anti-settlement capabilities. It is especially suitable for areas with low foundation bearing capacity and earthquake prone areas such as soft soil, expansive land, and collapsible LOESS. After the completion of the pipe connection, the site coating asphalt can completely avoid the erosion of perennial blisters and acid-base soils, ensure the service life and safety of personnel and equipment.
