Embodiment Construction

[0021] Figure 4 It is a partially dissected oblique view of the polyethylene pipe adopting the technology of the present invention, Figure 5 is along Figure 4 The polyethylene pipe C-C line used, the extracted cross-sectional view, Image 6 From Figure 5 From the polyethylene pipe used, the cross-sectional view of part D is extracted, Figure 7 yes Figure 5 Among the polyethylene pipes used, the cross-sectional view of part D of another example is extracted, and the description of the reinforced polyethylene pipe in the present invention is as follows.

[0022] A common polyethylene pipe (30) needs to form a fluid flow space (31) with a circular cross-section in which fluid can move. Outside the above-mentioned fluid flow space (31), there is a quadrangular hollow part (40) formed by a double wall (35) composed of an outer wall (32) and an inner wall (33) and a bridge-ridge (36). The characteristic of the present invention is that, in order to increase the strength ...

Abstract

The reinforced polyethylene pipe has double layer wall and into the hollow part between the two layers, stuffing material of waste plastic is filled to raise strength and specific weight. The reinforced pipe is used to replace cast iron pipe and favorable to solving environmental pollution. The reinforced pipe features the space for fluid to flow and with circular cross section; the outer wall, the inner wall and the ridges as connecting bridge in between forming quadrangular hollow parts; and the reinforcing stuffing filled into the hollow parts and of reused resin, which contains inorganic matter and is extruded and filled in the shape with flat cross section.

Description

technical field [0001] This invention relates to polyethylene pipes. More specifically, it relates to improving polyethylene double-walled pipes generally used in sewers and the like to maintain sufficient strength. Background technique [0002] Generally, polyethylene pipes used for sewer pipes etc. are extruded with polyethylene resin to form a square-shaped hollow inside, which is fused into a spiral shape and molded into a pipe body. [0003] The polyethylene pipe (1) formed by the above process, such as figure 1 , image 3 As shown; form a circular fluid flow space (2) that allows fluid to move, and the exterior consists of a double wall (5) composed of an outer wall (3) and an inner wall (4) and a connecting bridge-ridge (6) to form a quadrangular shape The hollow part (7). [0004] Compared with the single-walled polyethylene pipe, the above-mentioned general-purpose polyethylene pipe has the characteristics of superior strength and strong corrosion resistance due...
