Embodiment 1

[0024] The utility model relates to a non-excavation pipeline repair device, which is used for repairing the damaged position on the pipe wall of the sewer pipe, comprising: a repair auxiliary pipe, a sealing end cover and a reinforcement ring.

[0025] A sealing end cover is installed at the pipe port of the repair auxiliary pipe, and a reinforcing ring is installed outside the pipe port of the repair auxiliary pipe.

[0026] The inner diameter of the repairing auxiliary pipe is matched with the outer diameter of the pipe end cap, and the pipe end cap is installed on the inner wall of the repairing auxiliary pipe.

[0027] After the repair auxiliary pipe is connected with the sealing end cap, the repair auxiliary pipe and the sealing end cap are fastened together through a reinforcement ring to form an integrated repair capsule, which can withstand a certain pressure.

[0028] There is also a guide tube 4 in the inner center of the repair capsule, and the two ends of the guid...

Embodiment 2

[0030] A non-excavation pipeline repair device is used for repairing the damaged position on the pipe wall of the sewer pipe, comprising: a rubber pipe 1, a metal end cover 2 and a metal ring 3.

[0031] A metal end cap 2 is installed at the pipeline port of the rubber tube 1 for sealing, and a metal ring 3 is installed outside the pipeline port of the rubber tube 1 .

[0032] The rubber tube 1 is connected with the metal end cap 2, and then the rubber tube 1 and the metal end cap 2 are fastened together through the metal ring 3, so that it forms an integrated repair capsule and can withstand a certain pressure.

[0033] The repair auxiliary pipe adopts the rubber pipe 1, which can be used for inflation, and the repair capsule is expanded and stretched by compressed air.

[0034] The sealing end cover adopts the metal end cover 2, and the metal end cover 2 and the rubber tube 1 are fixed together by pressing, which has good sealing performance on the one hand and strong corros...

Embodiment 3

[0040] A trenchless pipeline repair method, comprising the steps of:

[0041] a. In the natural state, the repair capsule is wrapped with stretch film and then wrapped with resin-impregnated fiberglass cloth, and transported to the damaged sewer pipe wall through the sewer well;

[0042] b. Fill the repair capsule with compressed air. After the repair capsule is inflated, a certain pressure is formed and maintained. The pressure range is 1.0 Bar. After the repair capsule is inflated, it expands and stretches, so that the resin-impregnated fiberglass cloth wrapped around the repair capsule Close to the wall of the damaged sewer pipe;

[0043] c. The fiberglass cloth impregnated with resin is tightly attached to the wall of the sewer pipe under the pressure of 1.0Bar. After 10 minutes, the fiberglass cloth is gradually solidified, and then the gas of the repair capsule is discharged to return to the natural state, and it is transported out of the sewer, and the sewer is damaged....

Abstract

The invention discloses a trenchless pipeline rehabilitation device and method which are used for rehabilitation of damaged positions in the wall of a sewer pipe. The trenchless pipeline rehabilitation device comprises an auxiliary rehabilitation pipeline, a sealing end cover and a reinforcing ring; the sealing end cover is installed at a port of the auxiliary rehabilitation pipeline, the reinforcing ring is installed on the outer side of the port of the auxiliary rehabilitation pipeline, and the auxiliary rehabilitation pipeline and the sealing end cover are connected and then are fastened together through the reinforcing ring to form an integral rehabilitation capsule. In this way, the trenchless pipeline rehabilitation device and method do not damage infrastructures and meanwhile do not affect the surrounding environment and passage of roads, the time is saved, and construction cost is reduced; and the trenchless pipeline rehabilitation device and method can be used for rehabilitating and sealing gaps, holes, cracks and other damaged positions of a pipeline, so that the service life of the pipeline is prolonged, the diameter range of pipelines suitable of being rehabilitated is wide, and recycling can be achieved.

Description

technical field [0001] The invention relates to the technical field of trenchless pipeline repair, in particular to a trenchless pipeline repair device and a repair method thereof. Background technique [0002] At present, in most cities in my country, the repair method of pipeline damage is to adopt the method of excavating and reburying the pipeline for repair. [0003] However, with the progress of urbanization, urban underground pipelines are intricate, and the load on urban roads is becoming more and more serious, which causes a lot of problems in the process of repairing various pipelines. For example, the excavation of main roads seriously affects traffic and the environment. Other pressure pipelines bring great hidden dangers to excavation. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a non-excavation pipeline repairing device and a repairing method thereof. It does not cause damage to the infrastru...
