Description

Technical Field

[0001] This utility model relates to the field of cement pipe technology, specifically a high-pressure resistant cement pipe. Background Technology

[0002] Cement pipes, also known as cement pressure pipes or reinforced concrete pipes, can be used as drainage pipes in urban construction, for sewage discharge, flood control and drainage, as well as water supply pipes in some special factories and mines and farmland wells.

[0003] As disclosed in the patent announcement CN217951514U, a novel pressure-resistant cement pipe includes a cement pipe body, a reinforcing metal mesh, reinforcing steel bars, reinforcing springs, and locking bolts. The reinforcing metal mesh and reinforcing steel bars are fixed inside the cement pipe body. The reinforcing springs and locking bolts are fixed inside the central cavity of the cement pipe body. The reinforcing metal mesh and reinforcing steel bars form the first reinforcing structure of the cement pipe body, and the reinforcing springs and locking bolts form the second reinforcing structure of the cement pipe body. The beneficial effects of this utility model after adopting the above technical solution are: the structural strength and pressure-resistant buffering capacity are greatly improved through the structural reinforcement of the first and second reinforcing structures, as well as structural buffering, resulting in a long service life.

[0004] Although the aforementioned patents improve structural strength and compressive buffering capacity, the pressure resistance at the joints of multiple cement pipes after assembly and splicing is poor, making them prone to displacement or breakage due to external high pressure.
