Problems solved by technology

Although the surface of the fins where the flame goes is melted, the high temperature can also easily cause the decomposition and chain breakage of the plastic macromolecules, making it even more difficult to guarantee the quality of the welded joints.
Therefore, in ac

Embodiment Construction

[0029] Figure 1 ~ Figure 3 It is the pipe wall structure form of several typical plastic pipes with different rib structures as mentioned above, and will not be described again.

[0030] Figure 4 ~ Figure 6 It is the structure of several spiral corrugated plastic pipes in the structure form of the present invention. Its common basic structure is: the pipe wall of the pipe 1 is formed by a strip-shaped sheet 2 that is spirally wound with its center line as the axis, and the edges of the adjacent sheets in the spiral circumference are sequentially overlapped and fused. The continuous solid-wall tubular structure; the outer convex tendon-like reinforcement structure 4 in the same spiral winding form is joined to the pipe wall in a manner that spans the overlapping fusion seam 3 at the edge of each adjacent sheet material on the pipe wall. On the outer peripheral surface of the pipe wall structure, it is formed as a spiral corrugated plastic pipe with a helically wound externa...

Abstract

The present invention relates to spiral type corrugated plastic pipe material and its preparation method. The perparation method includes following steps: using a first extrusion mechanism to extrudethe fused bar shaped plastic sheet material used as pipe wall material which is wound around the pipe axis in the form of spiral-joint pipe with adjucent edges mutually lap-fused jointed successively, then using a press roller mechanism tightly press the spirally lap-fused joint to form the spiral-joint plastic pipe; similarly, using another extrusion mechanism extrudes corresponding rib type strengthening trapesoidal plastic tube and using the same spiral winding mode to press the said plastic tube on the spiral-joint of the above-mentioned plastic pipe to obtain the said corrugated plastic pipe.

Description

technical field [0001] The invention relates to a corrugated plastic pipe with a spiral reinforcing rib structure and a preparation method thereof. Background technique [0002] In urban sewer pipes and various sewage pipes, various forms of plastic pipes are used more and more. Because there is usually no pressure in the pipe, in order to improve its performance against external pressure or impact, there have been many reports and uses of plastic pipes with different forms of rib structures on the outer periphery of the pipe wall. At present, there are several kinds of plastic pipes with this structural form and corresponding preparation methods: one is the plastic pipes that are directly extruded. The most representative ones are double-wall corrugated pipes and circumferentially reinforced pipes formed by direct extrusion. The inner wall layer is a continuous and smooth surface, and the outer wall layer is a hollow corrugated structure or a solid annular rib structure. ...
