Plastic pipe with reinforcement embeded in the profile of spiral wall layer and goosewing and he that strength improves

摘要

The present invention relates to a two-wing spiral member synthetic resin tube with improved strength, the two-wing spiral member is formed in a spiral close contact with the spiral profile inside the square profile with grooves formed on both outer edges and the hollow portion, both wings are formed continuously The spiral member profile is spirally wound through a conventional winding forming apparatus, and the profile between the profile Bonding to the profile junction portion 30 of the shape, the profile junction portion 30 is formed of a synthetic resin tube of the present invention by bonding with a synthetic resin horizontally with both profiles (20).;It is to improve the load strength of the vertical earth pressure in the synthetic resin pipe which is a flexible pipe by strengthening the protection of the profile outer wall and the load strength of the profile and the profile joint through the double wing spiral member and the profile joint which constitute the synthetic resin pipe.;Detailed description of the synthetic resin pipes; One of the primary polyethylene or polypropylene and carbon black master batch for weather resistance, or by forming a square profile with a hollow portion made of a synthetic resin containing calcium carbonate, and a separate extruder and the square profile The double wing spiral member is molded from the same synthetic resin to form a double wing spiral member profile. And the wing 110 and the wall 120 of the two-blade spiral member is formed in a spiral with a predetermined thickness is to be formed in close contact with the profile.;In addition, the synthetic resin used in the two-blade spiral member in order to improve the load strength is excellent in one of the above-mentioned synthetic resins and polypropylene polymer resin (PP-LFT) containing a long fiber excellent in tensile strength or polyethylene polymer PE-LFT can be added to form a double wing spiral member synthetic resin composite tube with improved strength to further strengthen the load strength, and the polypropylene polymer resin (PP-LFT) as waste Polyethylene recycled resin selected from among those containing 15% to 50% long fibers in polyethylene polymer synthetic resin (PE-LFT), polyolefin recycled resin treated with waste, mixed with polyethylene recycled resin, polyethylene or, It is possible to improve load capacity by using recycled resin derived from primary processing of polypropylene. The strength, characterized in enhanced amount of the wings can be formed by a spiral member recycled plastic tube.;The present invention is formed according to the designation of the synthetic resin tube of the two-blade spiral member 100 and the strength of the two-blade spiral member is formed spirally while maintaining a constant distance in the longitudinal direction inside the rectangular profile with a hollow portion Alternatively, the spiral member 300 composed of three walls and three wings further strengthening the load strength according to the use The spiral member 300 composed of four walls and four wings outside the synthetic resin tube or the circular synthetic resin tube It has a feature that can be formed of a synthetic resin tube.; Double wing, spiral member, profile, plastic pipe, long fiber polymer resin (LFT)
