Problems solved by technology

[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

Embodiment 1

[0027] Firstly, reduce the water level of the pipeline to be repaired to the lowest point, use the breech dredging to remove most of the silt, and then perform high-pressure cleaning, and then use professional water blocking equipment and high-power sewage pumps to block and adjust the upstream and downstream of the pipeline water, and then use a high-pressure water cleaning vehicle to move from the upstream wellhead to the downstream wellhead and clean repeatedly until the pipeline meets the repair requirements. The pre-repair inspection is carried out between the pipelines to be repaired to confirm that the lining repair conditions are met. It is required that there is no pipeline collapse inside, the axial bending of the pipeline is less than 30 degrees, the pipeline error is less than 20mm, and there are no steel bars and sharp protrusions in the pipeline. Small areas of pipeline collapse, damage and sharp steel lamps need to be treated by local point repair in advance, and...

Embodiment 2

[0029] In embodiment one, add following operation:

[0030] In the step (2) of water blocking, the imported water blocking air bag and high-power sewage pump are used for water blocking. The auxiliary tools are SKW gasoline generator, air pump, gas meter, gasoline pump and hose, and the upstream wellhead of the pipeline to be repaired is blocked with an air bag. Water, the water pump cooperates with the temporary water transfer work after the water is blocked. The specific location is determined according to the actual location of the pipeline to be repaired. In step (3) the cleaning standard for the pipeline cleaning is no stones, sand, and no piles of silt.

[0031] Firstly, reduce the water level of the pipeline to be repaired to the lowest point, use the breech dredging to remove most of the silt, and then perform high-pressure cleaning, and then use professional water blocking equipment and high-power sewage pumps to block and adjust the upstream and downstream of the pipe...

Embodiment 3

[0033] In embodiment two, add following operation:

[0034] Before the inspection in step (7), cut off the tie head of the pipe mouth with a pneumatic cutting tool, and wipe the mouth with double-quick cement, and then carry out inspection and acceptance. After the inspection and acceptance, remove the upstream and downstream blockages, and restore the pipeline to water.

[0035]Firstly, reduce the water level of the pipeline to be repaired to the lowest point, use the breech dredging to remove most of the silt, and then perform high-pressure cleaning, and then use professional water blocking equipment and high-power sewage pumps to block and adjust the upstream and downstream of the pipeline Water, when blocking water, use imported water blocking air bags and high-power sewage pumps to block water. The auxiliary tools are SKW gasoline generators, air pumps, gas meters, gasoline pumps and hoses. Use air bags to block water at the upstream wellhead of the pipeline to be repaired...

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 reverse lining pipeline repair. Background technique [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. Contents of the invention [0003] The purpose of the present invention is to provide a CIPP reverse lined pipeline repair, to solve the problems raised in the above background technology. [000...
