Abstract

The invention provides a large-diameter anti-cracking PE pipe. The large-diameter anti-cracking PE pipe comprises a pipe body, wherein the pipe body is made of polyethylene materials, a barrel-shaped reinforcing layer is arranged in the middle of the pipe wall of the pipe body, the reinforcing layer is formed in a way that a metal net is rolled, six to eight inner reinforcing strips which are made of steel wires of which the diameter is 3 to 5 mm are arranged on the inner side of the reinforcing layer and are uniformly distributed along the length direction of a pipeline, outer reinforcing strips which are made and formed by bamboo strips or steel bands are arranged on the outer side of the reinforcing layer, concave-convex surface reinforcing ribs are arranged on the surface of the pipe body, and steel wires of which the diameter is 2 mm are arranged in the surface reinforcing ribs. By adopting the scheme, the large-diameter anti-cracking PE pipe has the advantages of reasonable structure and good anti-cracking and anti-deformation effects and is especially suitable for large-diameter pipelines above 0.8 meter.

Description

technical field [0001] The invention relates to building materials, in particular to a large-diameter anti-crack PE pipe for building drainage. Background technique [0002] The quality of the building drainage pipe is directly related to the maintenance cost of the building. Most of the existing building drainage pipes buried in the ground are PE pipes. Most of these PE pipes have a layer of mesh belt inside the pipe. This structure is used in large When the caliber pipe is used, it is easy to deform, has poor tensile resistance and low strength. Contents of the invention [0003] The object of the present invention is to provide a large-diameter anti-crack PE pipe with reasonable structure, high strength and good anti-crack effect. [0004] In order to achieve the above object, the technical solution provided by the present invention is: large-diameter anti-crack PE pipe, which includes a pipe body made of polyethylene material, and a cylindrical reinforcement layer is ...
