Detailed Description
The preferred embodiments of the present utility model will be further described with reference to the accompanying drawings.
As shown in fig. 1 and 2, an embedded reinforced polyethylene wound composite pipe comprises a pipe body 1, a winding insert 2 and an outer wrapping 3 wrapping the winding insert 2; the outer surface of the pipe body 1 is provided with double spiral ribs along the extending direction, a spiral groove (not labeled in the figure) is formed between the two spiral ribs 4, and the winding embedded part 2 and the outer cladding 3 spirally extend and wind along the surface of the pipe body 1 and are correspondingly embedded into the spiral groove; the lower surface of the outer wrapping layer 3 is welded with the surface of the pipe body 1 in the spiral groove, the outer wrapping layer 3 extends outwards and covers the spiral ribs 4 on two sides, and the outer wrapping layer 3 is welded with the surface of the pipe body 1 outside the spiral ribs 4, so that the winding insert 2 and the outer wrapping layer 3 are partially protruded outside the spiral groove; the winding insert 2 is a hollow tube, and the cross section of the winding insert 2 is circular; the pipe body 1, the spiral bead 4 and the winding insert 2 are all made of polyethylene.
When the embedded reinforced polyethylene winding composite pipe is extruded and molded, the double spiral bead 4 is usually further extruded and smaller polyethylene solid strips are wound on the pipe body 1 on the basis of the wound pipe body 1, and the double spiral bead 4 and the pipe body 1 are welded together at a higher temperature when the spiral bead 4 is just extruded; the winding insert 2 is made of a molded section bar or pipe with certain rigidity and toughness, the winding insert 2 and the outer cladding 3 are extruded simultaneously, and after extrusion, the winding insert 2 and the outer cladding 3 are wound along a spiral groove, so that the winding insert 2 and the outer cladding 3 are spirally extended and wound along the surface of the pipe body 1 and are correspondingly embedded into the spiral groove; accordingly, the outer cladding 3 may be selected from different materials depending on the different buried environments. The outer cladding 3 is welded with the pipe body 1 and the spiral rib 4 under the action of the higher temperature during the extrusion.
