Description

Technical Field

[0001] The utility model belongs to the technical field of HDPE double-wall corrugated pipes, in particular to a large-caliber HDPE double-wall corrugated pipe. Background Art

[0002] HDPE double-wall corrugated pipe, referred to as PE 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 service life. Its excellent pipe wall structure design greatly reduces the cost compared with pipes with other structures. And because of its convenient and reliable connection, it has been widely used at home and abroad, replacing a large number of concrete pipes and cast iron pipes.

[0003] Since the outer wall of the large-diameter HDPE double-wall corrugated pipe has an annular corrugated structure, the ring stiffness of the large-diameter HDPE double-wall corrugated pipe is greatly enhanced, thereby enhancing the resistance of the large-diameter HDPE double-wall corrugated pipe to soil load. However, in the existing technology, most large-diameter HDPE double-wall corrugated pipes are difficult to adapt to certain environments with harsh geographical conditions, resulting in a decrease in the toughness and rigidity of the large-diameter HDPE double-wall corrugated pipe itself, thereby affecting the effect of the large-diameter HDPE double-wall corrugated pipe on soil resistance.
