Cipp field curing repair device and method

Abstract

The invention discloses a cipp field curing repair device. The device comprises a transport car, a winch, a water plugging gasbag and a baking device; a liquefied natural gas tank, a steam boiler andan air blower are mounted on the transport car; one end of the transport car is fixedly connected with a high temperature-resistant hose; one end of the high temperature-resistant hose is fixedly connected with the baking device; the baking device is glidingly mounted in a to-be-repaired pipeline; one side of the air blower communicates with an air duct; one end of the air duct is mounted on the to-be-repaired pipeline; and one end of the baking device is connected with the winch through a hauling cable. According to the cipp field curing repair device, the inner walls of to-be-repaired pipelines can be baked through the baking device, and through high-temperature combustion, certain smudges which are difficult to clean are burnt or dried in a baking mode to be separated from the inner walls, so that the inner parts of the to-be-repaired pipelines are smooth and dry and then the hauling and curing of mounting hoses are facilitated; and meanwhile, the inner walls of the to-be-repaired pipelines are combined with the hose in a curing mode more tightly.

Description

technical field [0001] The invention belongs to the technical field of pipeline repair, and more specifically relates to a cipp field curing repair device. Simultaneously, the invention also relates to a cipp on-site curing and repairing method. Background technique [0002] Drainage pipes that have been in operation for decades are easily corroded, resulting in reduced pipe body strength, fracture, dislocation, and sewage leakage. When the ground is gradually emptied, municipal accidents such as ground subsidence that we often encounter will occur, causing huge loss of life and property. In order to prevent this dangerous situation from happening, similar non-excavation lining technology is being used to repair old pipelines in a planned way all over the world, and the development and application of this kind of repair technology is also flourishing in my country. [0003] CIPP in-situ curing method is a kind of underground pipeline repair technology in the non-excavation...

AI Technical Summary

Problems solved by technology

[0004] When the existing cipp technology is repaired, the inner wall of the pipeline to be repaired needs to be cleaned first. However, the ordinary cleaning method cannot clean the inside of the pipeline, and it contains dirt and water, which is not conducive to the installation and curing of the liner. ; Therefore, we need to propose a kind of cipp on-the-spot curing repair device and repair method that are convenient to remove dirt and moisture on the inner wall of the pipeline to be repaired
