Enhancement structure wall pipe material and manufacturing device and method thereof

Abstract

The invention provides an enhancement structure wall pipe material. The pipe wall is in a spiral circumference shape formed by spirally winding special-shaped strip-shaped plastic sectional materials by taking the central line as the axis, the edges of the adjacent special-shaped strip-shaped plastic sectional materials are integrated in a lap-joint mode to form a continuous solid wall tubular structure, an enhancement bonding sectional material in the same spiral winding type is pressed above the portions of lap-joint integrating lines of the edges of the adjacent special-shaped strip-shaped plastic sectional materials on the pipe wall in a crossed mode, and a polypropylene and polyethylene composite enhanced pipe in the same spiral winding type is pressed above the enhancement bonding sectional material in a crossed mode and is bonded with the pipe wall through a pressing wheel mechanism. The structure mode of the material is provided with the outer ripples, the outer surface area of the pipe material is improved, in the use process, the formed pipeclay joint effect is superior to that of a pipe A of the pipe material of the polyethylene winding structure, and in addition, due to the fact that the structural wall height is large, the pipeclay joint effect is better than that of a common double-wall corrugated pipe.

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.
