Description

A conveniently assembled reinforced reinforced pipe and its supporting mechanism

technical field

The utility model relates to the technical field of reinforced pipes, in particular to a conveniently assembled reinforced reinforced pipe and its supporting mechanism.

Background technique

Reinforced pipe refers to a pipe with a special structure that has a smooth inner wall and radial ribs on the outer wall. Since the radial ribs adopt an I-shaped steel structure, it has the advantages of light weight and high strength compared with traditional straight-walled pipes, reaching the same strength. The required reinforced pipe can save 40-60% of the material compared with the straight wall pipe. Its superior performance and good cost performance make the reinforced pipe widely used in urban construction drainage and sewage projects.

PVC-U (rigid polyvinyl chloride) reinforced pipe is another new type of PVC-U pipe produced by heating and extruding PVC resin and using special molds and forming processes. It is the product of high-tech development in the 1990s. Under the same external pressure load capacity, this kind of pipe saves 30% of the material compared with ordinary PVC-U solid wall pipe. The design purpose of PVC-U reinforced pipe is basically the same as that of PVC-U reinforced pipe, and it is actually a kind of structural wall pipe. As a large-diameter PVC-U pipe for buried drainage and sewage, its main purpose is to discharge sewage or rainwater to sewage treatment plants or rivers, lakes and seas under the action of gravity, and is widely used in municipal engineering construction. In addition, it can also be used in fields such as farmland irrigation, power communication, cable protection and industrial sewage discharge.

Generally speaking, PVC-U reinforced pipes are often buried underground for use, such as buried drainage pipes, which are non-pressure pipes and mainly bear external pressure loads (usually internal pressure loads are ignored), while existing PVC-U reinforced pipes Pipes made of pipes are flexible pipes with poor resistance to external pressure. The form of damage is that the external pressure load causes excessive deformation or buckling of the pipe, which makes it easy to rupture and cause serious consequences. This performance affects its wide application. , especially the application in larger cities is subject to certain restrictions.

At the same time, in some existing fields such as farmland irrigation, electric power communication, cable protection and industrial sewage discharge, it is necessary to install the reinforced pipe outside or when splicing according to the needs. inconvenient.
