Non-excavation type pipeline repairing integrated device and repairing method

Abstract

The invention provides a non-excavation type pipeline repairing integrated device and a repairing method, and relates to the technical field of pipeline repairing. The non-excavation type pipeline repairing integrated device comprises a traction part, a supporting part and a connecting part; the supporting part comprises an outer sleeve, an inner rotating shaft and a spiral elastic cage fixed between the outer sleeve and the inner rotating shaft, the outer sleeve sleeves the spiral elastic cage, an inclined wheel is arranged at the outer side of the spiral elastic cage, and the included angle between a rotating shaft of the inclined wheel and the axis direction of the spiral elastic cage is 30-60 degrees; the inner rotating shaft is arranged in the outer sleeve and is rotatably connected with the outer sleeve, and a clamping mechanism for locking the inner rotating shaft is arranged between the inner wall of the outer sleeve and the outer wall of the inner rotating shaft; the inner rotating shaft is rotatably connected with the connecting part; the outer sleeve is rotatably connected with the traction part; and a curing lamp and a nozzle are arranged on the outer sleeve. In order to overcome the defects in the prior art, the device can adapt to various pipeline inner diameter specifications, it is guaranteed that a repairing pipe is completely attached to the inner wall of a to-be-repaired pipeline, and repairing steps are reduced.

Description

technical field [0001] The present application relates to the technical field of pipeline repair, in particular, to a trenchless integrated pipeline repair device and repair method. Background technique [0002] The urban underground pipeline is the urban drainage system, which is an engineering facility system used to treat and discharge urban sewage and rainwater. With the passage of time, the drainage pipes will be aged to varying degrees or the pipe wall will be broken. When the pipe is damaged, it will cause urban drainage and need to be repaired in time. [0003] When the pipeline is damaged in a large area, it is generally necessary to dig out all the pipelines for replacement. However, the construction cost of this excavation-type operation method is high, and the road surface needs to be excavated, which seriously affects traffic; Under the action of UV curing (ultraviolet curing), the pipe is lined with the pipeline to be repaired, the construction amount is small...

Problems solved by technology

[0004] However, the existing trenchless pipeline repair needs to lay the hose, inflate it with air, tie the head and tie it, put in the curing light chain and tie the head, inflate it again and start curing; this method is very easy to cure the hose due to air leakage After that, it cannot completely fit the pipeline to be repaired; in this case, the blowing expansion step is changed to an arc-shaped plate support that can change the support radius, but the arc-shaped plate can only correspond to a pipe of one specification. The support radius of the arc-shaped plate and the outer surface of the arc-shaped plate cannot completely fit the inner wall of the pipeline to be repaired, so that the hose cannot be completely fitted to the pipeline to be repaired after curing. Therefore, there is an urgent need for a hose that can match various specifications. An integrated repair device that repairs the inner diameter of the pipe and ensures that the outer wall of the hose can completely fit the inner wall of the pipe to be repaired
