Double-plastics finned wound corrugated pipe and method for manufacturing same

Abstract

The invention discloses a double-plastics finned wound corrugated pipe and a method for manufacturing the same. A pipe wall of the double-plastics finned wound corrugated pipe is in the shape of a corrugated pipe which is squeezed and inflated and is integrated by means of spirally winding and hot melting, a bell socket and a spigot socket are respectively formed in two ends of the double-plastics finned wound corrugated pipe, cavities are arranged in corrugations of the pipe wall, strip-shaped plastic reinforcing ribs are arranged in the cavities and are perpendicular to the pipe wall, the outer edge of each plastic reinforcing rib is connected with a crest ring surface of the corresponding cavity by means of hot melting, and the inner edge of each plastic reinforcing rib is annularly connected with the other surface of the corresponding cavity by means of hot melting. The double-plastics finned wound corrugated pipe and the method have the advantages that the double-plastics finned wound corrugated pipe is good in ring stiffness and corrosion resistance and long in service life, and future maintenance investment is nearly zero; the bell socket and the spigot socket are connected with each other by means of electric hot melting, so that a system is good in airtight property, and forming machines implemented in a manufacturing procedure are simple and are low in investment and cost; the double-plastics finned wound corrugated pipe and the method can be widely applied to wall pipes with large and super-large apertures for drain and blowdown structures.

Description

technical field [0001] The invention relates to a structural wall pipe and a preparation method thereof. Background technique [0002] At present, there are many types of large-diameter and super-large-diameter drainage and sewage structure wall pipes, and the types of materials used are also different, such as polyvinyl chloride PVC, polyethylene PE or polypropylene PP, among which double-wall corrugated pipes are typical examples. There are many forming processes for structural wall pipes, such as twin-machine co-extrusion composite molding, extrusion and winding molding. In addition, structural wall pipes will also use metal materials such as steel strips, steel wires, flat steel, aluminum strips, etc. as reinforcements. In terms of structural form, there are corrugated corrugations, which can be divided into annular corrugations and winding corrugations; there are reinforced reinforced shapes, and reinforced reinforced shapes can also be divided into annular reinforced ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a double-plastic reinforced winding corrugated pipe and its preparation method, to solve the technical problem that the rigidity of the structural wall pipe ring decreases with time and to be easily corroded; and to solve the problem of ensuring that the structural wall pipe is firmly connected and does not leak question
