Description

Technical Field

[0001] The invention relates to the field of pipeline trenchless repair, in particular to a pipeline trenchless repair lining hose construction device and a construction method. Background Art

[0002] Pipeline trenchless repair technology mainly includes overall repair technology and local repair technology. Trenchless repair technology has attracted more and more attention and adoption due to its advantages such as low impact on the environment and fast construction speed.

[0003] Taking the UV light-curing pipe lining repair of trenchless pipe repair as an example, it uses glass fiber material permeated with resin to form a new lining layer inside the pipe, and then uses ultraviolet light to cure the resin, so that the lining hardens into shape. This method can be completed quickly, usually only 3 to 4 hours to achieve the purpose of pipe repair. It is suitable for repairing various defects with unlimited length and a pipe diameter range of 150mm to 2000mm.

[0004] Construction steps: Preliminary preparation (construction traffic maintenance, technical safety briefing, on-site investigation and measurement) → lining design (plan formulation, overall and local repair judgment) → dredging and cleaning (pipeline plugging and dredging, pipeline inspection) → pulling in lining hose (laying base membrane, pulling in hose) → UV curing (inflatable hose, UV curing) → port processing (cutting off the lining end, opening the branch pipe).

[0005] In the actual construction process, the lining hose usually needs to be customized according to the inner diameter and length of the repaired pipe, and folded and placed in a wooden box to protect the finished product and facilitate access during on-site construction; the pipe diameter range suitable for UV light-curing pipe lining repair is generally 0.15~2m, but it is limited by the wellhead size of the working well, which is generally 0.6~1m. Generally, before lowering the lining hose, it is necessary to fold the lining hose according to the wellhead size limit to ensure that it can pass through the wellhead smoothly and avoid friction with the wellhead and well wall as much as possible; when the pipe diameter to be repaired is large or the length is long, the lining hose is generally heavy and requires mechanical equipment for auxiliary construction; It is particularly necessary to improve the construction efficiency of pipeline trenchless repair lining hose through professional equipment and corresponding construction methods. Summary of the invention

[0006] The present invention aims to overcome the defects of the prior art and provide a pipeline trenchless repair liner hose construction device and a construction method to solve the problem of low construction efficiency of the trenchless repair liner hose.

[0008] The described pipeline trenchless repair lining hose construction equipment is characterized in that: the described folding machine includes a shell, longitudinal rollers and transverse rollers arranged in the shell, and adjustable supports installed at both ends of the rollers. The longitudinal and transverse rollers can be adjusted up and down and left and right through the extension and retraction of the adjustable supports to adapt to the folding of lining hoses of different sizes.

[0009] The described pipeline trenchless repair lining hose construction equipment is characterized in that it also includes a mechanical telescopic system, which is arranged on the upper part of the lining hose storage box and connected to the folding machine for adjusting the height of the folding machine.

[0010] The described pipeline trenchless repair lining hose construction equipment is characterized in that it also includes a self-tightening roller, which includes a jacking support and a roller. The self-tightening roller is arranged in the working well and is tightened on the concrete working well through an adjustable jacking support. The roller reduces friction to facilitate the lining hose traction construction.

[0011] The pipeline trenchless repair lining hose construction equipment is characterized in that the lining hose is towed by using a winch and a traction rope.

[0012] The construction method of the pipeline trenchless repair lining hose construction equipment is characterized by: preparing the pipeline trenchless repair lining hose construction equipment → completing the working well plugging and pipeline dredging and cleaning → installing the self-tightening roller in the working well → completing the installation of the terminal working well winch → the automatic trolley pulls the winch traction rope to the starting working well → traction bottom membrane laying → the automatic trolley pulls the winch traction rope to the starting working well → the traction rope passes through the folding machine → the lining hose passes through the adjusting roller → the traction rope is connected to the lining hose end restraint hoop → starting the winch to slowly pull the lining hose → the lining hose passes through the wellhead to the pipeline → adjusting the traction speed of the lining hose → the lining hose is pulled to a certain length in the terminal working well → the lining hose traction is completed.

Compared with the prior art, the shortcomings of slow manual folding efficiency of the lining hose, the need for a car crane to cooperate with the hoisting, and the need for a large site are optimized, especially the advantages of the lining hose with a large diameter are more obvious.

[0014] The vehicle operation platform also makes it more convenient to transport materials without the need for crane assistance. It can be parked in place for integrated operations at one time, occupying less space and reducing environmental impact. By setting up a folding machine, the lining hose can be automatically folded so that it can pass through the wellhead smoothly and avoid friction with the wellhead and well wall as much as possible, thus protecting the lining hose from damage; By setting a self-tightening roller in the working pit, the lining hose is ensured to avoid friction with the working pit and the pipeline wall as much as possible during the traction construction process, thus protecting the lining hose from damage; The application of this invention not only achieves the expected design goals, but also improves the construction efficiency and ensures the construction quality through the automation of the lining hose construction. It has also been highly recognized by all parties involved in the construction. The promotion and application of the technical ideas of the invention and the comprehensive benefits generated are the value embodiment of the company's ability to improve its core competitiveness in the market.
