Description

Technical Field

[0001] The utility model relates to the technical field of trenchless short pipe repair, in particular to a trenchless repair device for a pipeline using a lining method. Background Art

[0002] As we all know, urban drainage pipe network is the lifeline of urban industry and residents' domestic water supply, and the operation quality of water supply pipe is directly related to the safety and reliability of water supply. At present, many cities are using trenchless lining repair technology for water supply and drainage pipe repair projects, especially the repair construction of water supply and drainage pipes under busy urban roads. It is a safe, feasible and convenient repair construction method that can save construction funds and reduce construction costs, as well as speed up construction efficiency and ensure construction safety.

[0003] The process principle is to use pipeline detection, mechanical traction installation and other technologies to recreate a new layer of lining pipe in the old pipe with flexible materials and corresponding filling materials to repair the original pipe. The material is prefabricated as a lining pipe with a speed mat, which is pulled into the pipe by mechanical equipment, and the lining pipe is supported by water or air. The lining pipe is hardened by ultraviolet light, and then the gap between the lining pipe and the original pipe is filled with high-micro slurry. After the high-micro slurry is cured, the lining pipe is anchored to the inner wall of the original pipe to form a lining structure, which plays a role in anti-seepage reinforcement and maintenance.

[0004] Since the repair procedures such as injecting water or air to prop up the pipe, hardening the pipe with ultraviolet light, and filling the gaps by injecting high-micro slurry after hardening the pipe with external light all take a lot of time to complete, the entire repair process is inefficient and the repair time is long.

[0005] Therefore, how to design a pipeline lining method trenchless repair device that can support and harden the pipeline to facilitate high-micro-slurry filling of gaps at the same time is a technical problem that needs to be solved. Utility Model Content

[0006] In order to solve the above problems, the purpose of the utility model is to provide a non-excavation repair device for pipe lining, which solves the problem of having to wait for the ultraviolet lamp to harden the pipe when filling the gap between the lining pipe and the original pipe, resulting in low repair efficiency and long repair time.

[0007] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes a lamp post and a plurality of movable support devices equidistantly arranged along the length direction of the lamp post; the plurality of movable support devices each include a movable assembly equidistantly arranged along the circumference of the lamp post and a support assembly arranged between adjacent movable assemblies; the movable assembly includes a telescopic rod fixedly connected to the outer peripheral wall of the lamp post and a universal wheel fixedly connected to the telescopic end of the telescopic rod; the support assembly includes a telescopic support rod fixedly connected to the outer peripheral wall of the lamp post and an arc-shaped support frame fixed to the telescopic end of the telescopic support rod; the arc-shaped support frame includes a metal support frame, a transparent support plate embedded in the upper and lower end surfaces of the metal support frame, and an arc-shaped side plate slidably arranged on both sides of the metal support frame; the telescopic end of the telescopic support rod is fixedly connected to the transparent support plate; linear modules are arranged on both sides of the inner wall of the metal support frame, and the arc-shaped side plates are slidably installed on the linear modules on both sides; a plurality of ultraviolet lamps are equidistantly arranged on the outer surface of the lamp post along the circumference, and a plurality of ultraviolet lamps are also fixedly arranged on the inner side surface of the transparent support plate close to the telescopic support rod.

[0008] Furthermore, the transparent support plate and the arc-shaped side plates are both made of plastic materials with good permeability such as transparent polycarbonate.

[0009] Furthermore, the lamp post is provided with a power source for providing energy to the ultraviolet lamp and the mobile supporting device.

[0010] The utility model has the following beneficial effects:

The utility model realizes moving on the inner wall of the pipeline and supporting the pipeline through the movable support components arranged at intervals; when in use, the telescopic rod and the support component are extended synchronously, the outer side surface of the arc-shaped support frame contacts the inner wall of the pipeline while the universal wheel contacts the inner wall of the pipeline to support the pipeline, and the gap between the pipeline and the original pipeline is filled with high-micro slurry while hardening the pipeline by ultraviolet light, thereby improving the work efficiency of pipeline repair.
