Circular pipeline feeding type overall rehabilitation equipment and rehabilitation method thereof

Abstract

The invention relates to the technical field of pipeline maintenance equipment, in particular to circular pipeline feeding type overall rehabilitation equipment and a rehabilitation method thereof. The equipment comprises a concentric positioning device, feeding devices, a sealer, an advancing device and a pressurizing oil rod; the concentric positioning device comprises a main ring body and a secondary ring body which are coaxial and are connected with each other; a group of fastening members are arranged on the front side face of the main ring body and on the front side face of the secondaryring body respectively; two feeding devices are provided and the two feeding devices are symmetrically arranged on the rim of the secondary ring body; each of the feeding devices is flexibly matchedwith the secondary ring body via a container; the sealer comprises a hollow disc and a rubber airbag; an inwardly concave installation groove is formed in the outer surface of the hollow disc; the rubber airbag wraps the outer part of the hollow disc via the installation groove; the backside of the hollow disc is horizontally and flexibly arranged at the front end of the advancing device via the pressurizing oil rod; and a suspended guider is arranged on the front side of the hollow disc. The equipment and the method can improve the quality of grouting and thereby improves the service life ofa pipeline after rehabilitation.

Description

technical field [0001] The present invention relates to the technical field of pipeline maintenance equipment, in particular to a circular pipeline feeding type integral repair equipment and a repair method thereof. Background technique [0002] Pipelines such as main pipelines of sewers buried underground have conventionally used ceramic pipes, concrete pipes made of concrete, and polyvinyl chloride pipes made of synthetic resins. However, due to the aging of these pipes or the subsidence of the underground foundation Due to changes in ground pressure and ground pressure, failures such as cracks, damage, and separation of joints may occur. At present, in the renewal and repair of underground pipelines, many construction techniques such as trenchless expansion (expansion) pipes, rammed pipes, interspersed pipes, and lined pipes are used. [0003] Among them, the so-called non-excavation intubation repair process is powered by traction or jacking equipment, passing a new pip...

AI Technical Summary

Problems solved by technology

In order to allow the repaired pipeline to be used for a long time, both ends of the grouting area need to be sealed. Otherwise, in future use, the fluid may damage the internal structure of the grouting area, resulting in the disintegration of the repaired overall structure. One of the two ends of the slurry area is outside the damaged pipeline, which is easy to deal with, but the other end is inside the damaged pipeline, which is troublesome to realize, and the existing equipment for realizing this process does not have this function
