[0002] The urban underground pipeline system is an important part of modern urban infrastructure. However, due to factors such as service life, construction quality and environmental impact, pipeline damage and leakage are common.

[0003] At present, the traditional pipeline repair method usually requires excavation of the ground, which not only affects traffic but also has a long construction period. With the development of science and technology, lined hoses are usually used to repair pipelines. In the process of connecting the front end of the lined hose to the blower or other pipelines, the front end of the lined hose is connected to the blower or other pipelines by a cable tie. When liquid or gas is transported for a long time through the lined hose, the connection between the front end of the lined hose and the blower or other pipelines becomes loose. At the same time, the lined hose is only secured by a cable tie, which has poor sealing performance.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0009] Preferably, the outer side wall of the outer sleeve is provided with a thread groove, and by providing the thread groove, the connectivity between the outer ring of the lining hose and the inner ring of the repair pipe is increased by adhesive.

[0010] Preferably, a filler layer is provided inside the outer sleeve, and the filler layer is specifically an aluminum oxide layer. By providing the filler layer, the density and thermal properties of the glass fiber can be adjusted.

[0011] Preferably, a middle layer is arranged outside the inner layer, and the middle layer is specifically a glass fiber layer. By arranging the middle layer, the lining hose has the characteristics of high pressure resistance, high wear resistance, hydrolysis resistance and the like.

[0012] Preferably, a buffer column is provided between the inner layer and the filler layer, and the impact resistance of the lining hose is further increased by providing the buffer column.

[0013] To sum up, the technical effects and advantages of the utility model are as follows: the new liner hose structure for pipeline repair, through the coordinated use of the transmission pipe and the one-way valve, is convenient for transmitting gas to the interior of the annular air bag ring, and through the action of the groove, the annular air bag ring is convenient for installation at the front end of the liner hose, and then through the action of the annular air bag ring, it is convenient for repair personnel to connect the front end of the liner hose and the blower through a cable tie.

Its function is to protect the fiber reinforcement layer, prevent the internal resin from flowing out, and also avoid the problem of uneven material curing. In addition, the inner layer 11 also has a certain toughness, which can prevent it from being blown during the operation process, thereby ensuring the smooth progress of the resin curing operation. The gas is transmitted to the interior of the annular airbag ring 3 through the transmission pipe 4, so that the annular airbag ring 3 slowly expands. The repair personnel connects the front end of the lining hose to the pipeline or blower through a cable tie to increase the connectivity and sealing of the front end of the lining hose.

[0022] Reference Figure 3 The transmission pipe 4 is fixedly connected with a vent pipe 6, and the top of the vent pipe 6 is threadedly connected with a closing cover 7. The inner wall of the closing cover 7 is matched with the outer wall of the top of the vent pipe 6. The inside of the closing cover 7 is fixedly connected with a sealing plug 8. The sealing plug 8 is mainly composed of rubber material and has a certain elasticity. The sealing plug 8 is tightly attached to the vent pipe 6, and the closing cover 7 and the sealing plug 8 can seal the vent pipe 6.

[0023] Reference Figure 2 The outer wall of the outer sleeve 1 is provided with a thread groove 9, which is arranged in a threaded shape on the outside of the outer sleeve 1, so that the adhesive remains on the outer surface of the outer sleeve 1, thereby increasing the connectivity between the outer ring of the lining hose and the inner ring of the repair pipe.

[0024] Reference Figure 1 and Figure 4 A filler layer 12 is disposed inside the outer sleeve 1, and the filler layer 12 is specifically an aluminum oxide layer. The filler layer 12 can also be a silicate, which is used to adjust the density, thermal performance and cost of the glass fiber.

[0025] Reference Figure 1 and Figure 4A middle layer 13 is arranged outside the inner layer 11, and the middle layer 13 is located between the inner layer 11 and the filler layer 12. The middle layer 13 is specifically a glass fiber layer 10. The middle layer 13 is woven into a hose by multiple layers of glass fibers, and then impregnated with photocurable resin and initiator, etc. This layer provides the hose with high pressure resistance, high wear resistance, hydrolysis resistance and other characteristics, ensuring the stability and service life of the hose in complex environments.

[0026] Reference Figure 4 A buffer column 14 is arranged between the inner layer 11 and the packing layer 12. The buffer column 14 is mainly composed of rubber material and has a certain elasticity. The buffer column 14 further increases the impact resistance of the lining hose.

[0027] Working principle: First, the inner lining hose is made through the outer sleeve 1, the inner layer 11, the filler layer 12, and the middle layer 13. The middle layer 13 is made of glass fiber. Multiple layers of glass fiber are woven into the middle layer 13, and then impregnated with light-curing resin and initiator to form the middle layer 13. The filler layer 12 is made of silicate or aluminum oxide to adjust the density, thermal performance and cost of the glass fiber. A buffer column 14 is added between the inner layer 11 and the filler layer 12 to further increase the impact resistance of the inner lining hose. The inner layer 11 is a layer of transparent polymer film material, which protects the fiber reinforcement layer and prevents the internal resin from flowing out. At the same time, it also avoids the problem of uneven curing of the material. The outer sleeve 1 is made of a high-barrier polymer film material, which protects the internal fiber reinforcement layer and the inner protective layer to avoid erosion by the external environment.

[0028] During the repair process using the liner hose, the front end of the outer sleeve 1 is connected to the blower, and the front end of the outer sleeve 1 is turned out a certain distance and connected to the blower, and then gas is transmitted to the interior of the annular airbag ring 3 through the transmission tube 4, causing the annular airbag ring 3 to expand. At this time, the outer circumference of the annular airbag ring 3 is larger than the outer circumference of the outer sleeve 1, and the expanded annular airbag ring 3 is squeezed by a cable tie to increase the sealing of the connection between the front end of the outer sleeve 1 and the blower. Secondly, when the front end of the outer sleeve 1 is mounted on other pipes, the expanded annular airbag ring 3 can be compressed with a cable tie, so that the inner wall of the outer sleeve 1 fits tightly with the tail end of the transmission pipe 4, and the stability of the connection between the two pipes is further increased.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
