Problems solved by technology

[0006] Both patents indicate that the reinforced inner rib not only serves as a welding joint surface, but also provides reinforcement. However, under the condition of uneven force, the force is concentrated on the top of the hollow rib, so that the force will flow to both sides of the hollow rib. Side extrusion, resulting in hollow ribs on both sides of the depression, broken, can not guarantee the stability and ring stiffness of the pipe
In addition, the area of ​​the joint surface is small during welding. In actual use, the hollow reinforcement may be degummed and separated due to poor adhesion.

Abstract

The invention provides an HDPE-reinforced corrugated plastic wall tube which comprises a cylindrical tube body and hollow reinforced tubes. The hollow reinforced tubes spirally wind on the outer wallof the tube body. The hollow reinforced tubes are internally provided with reinforced ribs. Each reinforced rib consists of two intersecting rid bars, and each inner part of the hollow reinforced tubeis divided into four hollow cavities. The reinforced ribs can bear higher pressure, distributed-type force is more uniform, ring-rigidity and stability of the tubes are strengthened, depressions of the two sides of the hollow reinforced tubes caused by overconcentrated force do not occur, non-deformation of the hollow reinforced tubes is guaranteed, so that strength and stability of the HDPE-reinforced corrugated plastic wall tube are better than the strength and stability of other winding corrugated tubes and double-wall corrugated tubes; the area of the welding junction surface is large when welding, adhesiveness is better in practical use, and unglued separation does not occur.

Description

technical field [0001] The invention belongs to the field of polyethylene winding structure wall pipes, in particular to HDPE reinforced corrugated plastic winding structure wall pipes. Background technique [0002] In sewage treatment, sewage pipes are indispensable, and various forms of plastic pipes are used more and more, gradually replacing traditional cement pipes, and have a large market. [0003] The corrugated corrugated pipe in the prior art, in the process of use, the corrugation of the corrugated corrugated pipe is often concentrated and uneven due to the force on the top of the corrugation, resulting in the top of the corrugation not being sunken, and the two sides are sunken, and the corrugation is broken. [0004] Chinese patent, patent No. 2011201485196, proposes "inner rib reinforced outer corrugated plastic winding structure wall pipe", which includes a pipe body formed by spirally winding and welding the pipe body. The pipe body includes a cylindrical pipe...
