Description

Technical Field

[0001] The utility model relates to the technical field of sewage pipes, in particular to a buried sewage pipe. Background Art

[0002] Rigid polyvinyl chloride, UPVC, also known as hard PVC, is an amorphous thermoplastic resin made by the polymerization reaction of vinyl chloride monomer plus certain additives (such as stabilizers, lubricants, fillers, etc.). Polyvinyl chloride material has many advantages such as light material, flame retardancy, good acid and alkali resistance, and simple processing.

[0003] A municipal sewage pipe disclosed in the existing publication number CN108150751B is a pipe in which a plurality of HDPE double-wall corrugated pipes are connected together by plugging a plug and a slot into each other, and then water is injected into the gap between the plug and the slot. After a period of time, the water-soluble film is dissolved by the water. At this time, the water directly contacts the quicklime powder, generating a large amount of heat so that the outer wall of the plug and the inner wall of the slot are partially melted and connected together to form a sealing surface.

[0004] The existing technology realizes the connection of pipelines by directly contacting water with quicklime powder, which is too troublesome in actual operation and affects the construction efficiency. Therefore, we propose a buried sewage pipe. Utility Model Content
