Description

Technical Field

[0001] The utility model relates to the field of corrugated pipes, in particular to a large and small double-wave reinforced Y-shaped reinforced pipe. Background Art

[0002] Polyethylene corrugated pipe is a special pipe material, which is mainly made of high-density polyethylene resin. This pipe has a series of advantages, including light weight, good toughness, good anti-sedimentation performance, fast construction, long service life, etc. At the same time, it also has high ring stiffness, good flexibility, excellent mechanical structure, good corrosion resistance and aging resistance, etc. It is mainly used in the field of sewage and drainage pipe technology.

[0003] Most existing corrugated pipes adopt the form of a single peak, and the cross-section of the corrugation is a "U"-shaped groove, which improves the rigidity of the corrugated pipe to a certain extent, but the rigidity improvement is limited. In addition, the corrugated pipe will be subjected to external tension and impact during transportation or hoisting. If the external impact exceeds the bearing range of the corrugated pipe, it will cause foreign rocks to break through the inner wall and cause water seepage when the original soil is backfilled.
