A cipp flip-lined pipeline repair

Abstract

The invention discloses a CIPP overturning liner pipeline repairing device, comprising the following steps: pipeline dredging: reducing a water level of a pipeline to be repaired to a lowest point, and after pulling chamber dredging is adopted to remove most deposits, performing high pressure cleaning work and comprehensive water plugging; adopting a special water plugging device and a large power sewage pump to perform water plugging and water transferring on an upstream and a downstream of the pipeline, and cleaning the pipeline; and enabling a high pressure water cleaning vehicle to enter from an upstream well mouth to move to a downstream well mouth for repeated cleaning till the pipeline meets the repairing requirement, and meanwhile, enabling a CCTV detecting device to enter from the upstream well mouth to monitor among the pipelines to be repaired and to match with the high pressure cleaning work. The CIPP overturning liner pipeline repairing device adopts a non-excavation technology and is short in construction time, site operation is finished in 24 hours generally, construction devices have a small floor area, a liner pipe and an old pipe are tightly combined, the strength is high, the service life can reach 50 years at most, and the CIPP overturning liner pipeline repairing device has small influence on traffic and is less affected by the environment, and thus the construction cost is reduced.

Description

Technical field [0001] The invention relates to the technical field of pipeline repair, in particular to a CIPP inverted lining pipeline repair. Background technique [0002] After many years of use, water supply pipelines will be damaged to varying degrees due to aging, which can easily cause muddy water or leakage, which affects the water supply quality of the entire water supply system. With the development of cities, underground pipelines become more and more complex. In many cases, After the water supply pipeline is damaged, the site does not have the location to re-lay a new pipeline, and the impact on the traffic and urban environment is also great, the cost is high, and the economy is poor. The traditional inverted lined pipeline repair method cannot solve this problem. Summary of the invention [0003] The purpose of the present invention is to provide a CIPP turnover lining pipeline repair to solve the above-mentioned problems in the background art. [0004] In order to a...

[0002] After many years of use, the water supply pipeline will be damaged to varying degrees due to aging, which will easily cause muddy water or leakage, and affect the water supply quality of the entire water supply system. With the development of the city, the underground pipeline is becoming more and more complicated. In many cases, After the water supply pipeline is damaged, there is no place to lay a new pipeline on site, and it also has a great impact on traffic and urban environment, high cost, and poor economy. However, the traditional repair method of flipping the lining pipeline cannot solve this problem
