Deformation recovery device for deep underground plastic pipe, and use method thereof

Abstract

The invention provides a deformation recovery device for a deep underground plastic pipe. The deformation recovery device for the deep underground plastic pipe comprises a precession cone and hangingrings, wherein the precession cone comprises a front-end precession cone, a middle-section cylinder and a rear-end precession cone; round steel is arranged at the middle part of the precession cone; and the hanging rings are arranged at the two ends of the round steel separately. According to the device and the use method thereof, the recovery device is effectively prevented from being re-deformedand blocked; the problems of deformation and blockage of a plastic pipeline are thoroughly solved; the purpose of normal water supply and drainage is achieved; the engineering quality is effectivelyimproved; the serious noise pollution of a temporary power generator in a construction field, and the adverse factors of high cost, long construction period, influence on a surrounding environment anda building, and the like in a large excavation method in a traditional process are avoided; and the device and the use method thereof have wide applicability in the field of repair for deep plastic pipes.

Description

technical field [0001] The invention relates to the field of repairing engineering water supply and drainage plastic pipes, in particular, the invention specifically relates to the technical field of repairing deeply buried underground plastic pipes. Background technique [0002] Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, plastic pipes have the advantages of energy saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall without scaling, easy construction and maintenance, and long service life. Widely used in building water supply and drainage, urban and rural water supply and drainage, city gas, electric power and optical cable sheathing, industrial fluid transportation, agricultural irrigation and other construction, municipal, industrial and agricultural fields. [0003] By 2015, in new construction, reconstruction and expansion projects across the country, 85% of buildi...

AI Technical Summary

Problems solved by technology

[0008] In view of the construction methods such as the large excavation method "traumatic surgery", the deformation compensation prevention method, and the deformation and blockage plastic tube repair method "endoscopic repair" in the existing technology, not only mechanical equipment and raw materials are required, but also the project quality is unstable and the effect is not good. , the deformation part is very easy to leak water, forming a leaking channel, causing serious damage to the engineering entity structure, and seriously threatening the technical problem of th
