Non-excavation pipe restoration profile and special-shaped pipe formed by winding of profile

Abstract

The invention relates to a non-excavation pipe restoration profile. The profile is characterized in that the profile is formed by a profile body, spherical clamping heads, spherical clamping grooves,reinforcing grooves, reinforcing ribs, sealing pads and anti-slip tongue plates. The invention further relates to a special-shaped pipe formed by winding of the non-excavation pipe restoration profile. The special-shaped pipe comprises a special-shaped pipe body, and the special-shaped pipe body is formed in the mode that the restoration profile winds helically. The special-shaped pipe is characterized in that one spherical clamping head of the restoration profile is clamped to the spherical clamping groove of next circle, after winding circle by circle, the special-shaped pipe body is fixedlyformed, and one anti-slip tongue plate abuts against the outer wall of the reinforcing groove of next circle. The non-excavation pipe restoration profile is scientific and reasonable in structure anddesign and has the advantages that the profile is good in restoration quality, does not easily rebound and is good in leakproofness, convenient to form and easy to achieve, and the non-excavation pipe restoration profile and the special-shaped pipe formed by winding of the profile have high innovativeness.

Description

technical field [0001] The invention relates to a repairing profile and a repairing pipeline, in particular to a repairing profile and a pipeline suitable for non-excavating pipelines, in particular to a non-excavating pipeline repairing profile and a special-shaped pipeline wound by using the profile. Background technique [0002] Urban drainage pipes are called the "underground lifeline" of the city, which shoulders the important task of urban sewage and waterlogging. As the scale of urban construction in my country continues to expand, more and more attention has been paid to the maintenance and repair of drainage pipes. The traditional method of pipeline repair is to use excavation to replace new pipelines, which results in a huge amount of engineering, consumes more manpower and material resources, and cannot complete the construction in a short period of time, which will lead to traffic jams, environmental pollution and other problems. These are modern cities. The con...

Problems solved by technology

However, the existing repair pipelines are relatively single in structure because they are used for forming the profiles of the pipelines. The specific performances are as follows: 1. Since the profiles of the pvc material have certain elasticity, after the special-shaped pipelines are formed, the bends are prone to occur. Springback affects the repair quality of the pipeline; 2. After the profile is spirally wound, the sealing effect at the interface is not ideal; 3. The slots and clips of the existing profiles are mostly triangular structures, that is, the triangular clips are vertically pressed into the triangle However, when the two are pressed in, the assembly can only be completed in the vertical direction. Therefore, when winding, the conveying angle of the profile must be ensured, and the operation is more cumbersome.
