Description

Resistance to compression formula PE water pipe structure Technical Field The utility model relates to the technical field of pipes, in particular to a compression-resistant PE water pipe structure. Background The PE water pipe is a plastic pipe made of polyethylene as a main raw material, has excellent comprehensive performance and is widely applied to the fields of water supply and drainage, fuel gas transportation, agricultural irrigation and the like. The traditional PE water pipe is relatively simple in structure, is usually only subjected to external pressure by means of a single-layer PE material, but the PE water pipe with a single structure can possibly maintain a normal working state when facing to slight pressure, is easy to deform or even crack when encountering the slight pressure, so that water resources are wasted, the surrounding environment is damaged, normal operation of engineering is affected, maintenance cost and time cost are increased, and secondly, the traditional PE water pipe is lack of an effective pressure dispersing structure, when the local pressure is too high, local deformation and cracking are extremely easy to occur, leakage of the whole water pipe system is caused, normal use and service life of the water pipe are seriously affected, in addition, the traditional PE water pipe is reduced in toughness at low temperature and is more easy to crack due to the pressure, the PE material is easy to soften at high temperature, compressive strength of the PE water pipe is reduced, and when the PE water pipe is subjected to the external pressure, the PE water pipe is extremely easy to deform and service life is reduced.
