Research, development and manufacturing of trenchless ultraviolet type pipeline in-situ curing and repairing hose

Abstract

The invention relates to a manufacturing method of a trenchless ultraviolet type pipeline in-situ curing and repairing hose. The trenchless ultraviolet type pipeline in-situ curing and repairing hose comprises a PE (polyethylene) shading film, glass fibers, a PET (polyethylene terephthalate) inner film, a resin pouring pipe, a spring, a first rubber cover plate, a second rubber cover plate, an air hole, an annular pipe and a pipe orifice, wherein the glass fibers are paved in the PE shading film; the resin pouring pipe and the spring are inserted into the glass fibers in a penetrating mode; the first rubber cover plate and the second rubber cover plate are installed at the two ends of the PE shading film; the air hole is formed in the first rubber cover plate; and the pipe orifice is formed in one side of the annular pipe. According to research, development and manufacturing of the trenchless ultraviolet type pipeline in-situ curing and repairing hose, the resin pouring pipe and the spring are arranged in the glass fibers, so that the glass fibers are supported, the cured resin and the cured glass fibers are prevented from being broken, and the durability is improved; and the glass fibers can be quickly soaked through the resin pouring pipe, so that the working efficiency is improved, and the occupied area of a conventional soaking mode is reduced.

Description

technical field [0001] The invention relates to the technical field of underground pipeline repair, in particular to a method for manufacturing a non-excavation ultraviolet type pipeline in-situ curing repair hose. Background technique [0002] Almost all drainage pipes in cities are individual, with different diameters and shapes, and special requirements for aggressive water flow and mechanical load-bearing capacity. In addition, local conditions are also quite different. Therefore, the fiberglass hose lining device with very good material properties can adopt flexible and diverse solutions, and adopt a relatively fast installation and construction method to meet the non-excavation lining repair of drainage pipes. Higher requirements to achieve the purpose of saving costs and prolonging the service life of the pipeline. CIPP trenchless repair with UV curing method can produce hoses with a length of up to 500M. Even if the size of a section of the pipe changes, or the pipe...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for manufacturing a non-excavation ultraviolet pipeline in-situ curing repair hose to solve the need to soak the glass fiber on site and then coat it in order to solve the above-mentioned background technology. The efficiency of construction is reduced, and it takes up a large area of ​​the site. Simply using light-curable resin and glass fiber to cure, the strength is relatively low, and the durability is insufficient.
