Continuous twining reinforced structure wall pipe, manufacturing equipment and manufacturing method

Abstract

The invention provides a continuous twining reinforced structure wall pipe. The pipe wall of the continuous twining reinforced structure wall pipe is a spiral circumference; a center line is considered as an axis for specific strip-shaped plastic materials to twine in a spiral manner; the edges of the each adjacent specific strip-shaped plastic materials are overlapped to be integrated with each other to form a continuous solid wall pipe-shaped structure; reinforced adhesive materials which has the same spiral twining form is straddled and pressed on the positions on which overlapping joints of the adjacent specific strip-shaped materials are positioned; a specific single wall corrugated pipe which has the same spiral twining form is straddled and pressed on the reinforced adhesive materials; a strip-shaped material which has the same spiral twining form straddles the specific single wall corrugated pipe in a pressing manner, and adhesive to the pipe wall through a pressing wheel mechanism.

Description

technical field [0001] The present invention relates to reinforced structural wall pipes, and also relates to the manufacturing equipment and manufacturing method of the pipes. Background technique [0002] In urban sewer pipes and various sewage pipes, various forms of plastic pipes are used more and more. Since there is usually no pressure in the pipe, in order to improve its resistance to external pressure or impact, different forms of rib structures are provided on the outer periphery of the pipe wall. At present, there are several types of plastic pipes with this structure and corresponding preparation methods: [0003] One is a plastic pipe that is directly extruded. The most representative ones are double-wall corrugated pipes and circumferentially reinforced pipes that are directly extruded. The inner walls of these two pipes are continuous and smooth. The axial partial section structure of the pipe is shown in (a) and (b) of Figure 1, respectively. The outer wall ...

Problems solved by technology

Although the surface of the fins where the flame goes is melted, the high temperature can easily cause the decomposition and fracture of the plastic macromolecules, and the quality of the welded joints is even more difficult to guarantee.

Therefore, in actual use, it can be seen that when these pipes are knocked or partially squeezed during loading, unloading, transportation or construction, it is often easy to cause cracks at the welded joints of the pipes, or spread out and be damaged in the form of a helical spring.
