Problems solved by technology
[0004] The existing polyethylene double-wall corrugated pipe anti-stress detection device only deforms the polyethylene double-wall corrugated pipe by simple knocking, etc., and the deformation amount of this deformation is small, which is not convenient to realize the simulation of polyethylene double-wall corrugated pipe. The anti-pressure detection work of the bellows in use may easily lead to a lack of accuracy in the detection results of polyethylene double-wall bellows

Description
technical field [0001] The invention relates to the technical field of anti-stress detection devices, in particular to a device capable of detecting anti-stress of polyethylene buried double-wall corrugated pipes. Background technique [0002] Polyethylene double-wall corrugated pipe is a new type of pipe with smooth inner wall and ring-shaped corrugated outer wall produced by three processes of pipe forming, cutting and flaring, with high-density polyethylene as the main raw material. Polyethylene double-wall corrugated pipe The material has strong chemical stability, strong aging resistance and environmental stress cracking resistance, and the hollow and ring-shaped corrugated structure greatly enhances the ring stiffness. Compared with concrete pipes and cast iron pipes, this kind of pipe is not only cheaper to purchase, but also The construction and installation are simple, which greatly reduces the construction cost and labor expenditure. The smooth inner wall of the po...
