Description

Technical Field

[0001] The present invention relates to the technical field of pipeline repair, in particular to a light-curing repair device for a municipal pipeline with large local deformation. Background Art

[0002] Municipal rainwater and sewage pipes may develop various problems during use, such as aging, damage, and leakage. If these problems are not repaired in a timely manner, they may lead to serious consequences such as pipeline failure and environmental pollution. Large local deformation is one of the more common problems. Common repair methods include partial replacement, local reinforcement, and internal pipe repair. Among them, local reinforcement and internal pipe repair of trenchless repair methods are widely used due to their advantages such as convenient construction, low environmental disturbance, and short repair cycle. Existing repair methods generally use a combination of airbag support and in-situ curing to form a new reinforced pipe within the original pipe.

[0003] The existing application number is: 202111073476.4 A light-curing lined pipe repair method discloses a method of adding a protective film to improve the curing strength.

[0004] However, in the actual repair process, the existing repair methods are difficult to restore the depressions in large deformed areas due to the limited pressure of the airbags. It is also difficult to achieve precise solidification of the protective film at the deformed position using the support of the airbags, resulting in frequent problems such as reduced water-passing cross-section of the pipeline after repair and local protrusions and siltation.

[0037] The guide wheel system 2 squeezes the spring A213 through the slider 214 to adjust the rotation opening and closing angles of the three groups of support rods 215, so that the three groups of support rods 215 and the roller 217 fit the inner wall of the pipe 5, supporting the entire roller system 1 at the center of the pipe 5 and providing sliding support in the extension direction of the pipe 5; the two traction ropes 23 are respectively connected to the top of the guide wheel system 2, which are used to pull the entire device to move in the pipe 5, so as to achieve the purpose of horizontally adjusting the position of the repair system 3.

[0045] The counter-support device 37 is used to provide a counter-support force for the jacking and curing device 36.

[0046] The actual repair process is as follows:

[0047] S1: The outer controller 42 transmits a signal to the inner controller 41 to start the motor B 323, and the carbon-glass mixed woven cloth 31 is pulled out from the feeding wheel 32, sequentially passes through the two guide wheels 33, the spraying device 34, the coating device 35, the jacking and curing device 36, and the cutting device 38 as shown, and then the motor B 323 is turned off. Figure 5

[0048] S2: The contraction guide wheel A 21 and the guide wheel B 22 are retracted, and after the whole device is sent into the pipeline 5 from the maintenance opening, the guide wheel A 21 and the guide wheel B 22 are naturally opened, and the whole roller system 1 is supported at the center of the pipeline 5. The outer controller 42 transmits a signal to the inner controller 41 to start the front camera 39, and the whole device is pulled in the pipeline 5 by using the traction rope 23, and the situation in the pipeline 5 is observed in real time by using the outer controller 42.

[0049] S3: After the front camera 39 observes the large deformation part 51, the traction is stopped, and the outer controller 42 starts the motor A 13, which can drive the rotating barrel 12 to rotate until the repair system 3 is aligned with the large deformation part 51 through the gear 15.

[0050] S4: The outer controller 42 transmits a signal to the inner controller 41 to start the motor B 323 and the feeding pump 343. The feeding wheel 32 transmits the carbon-glass mixed woven cloth 31 backward, and the nozzle 345 sprays the light-curing resin on the upper surface of the carbon-glass mixed woven cloth 31. After the carbon-glass mixed woven cloth 31 on the jacking and curing device 36 is completely sprayed with the light-curing resin, the motor B 323 and the feeding pump 343 are turned off. The whole device is pulled in the pipeline 5 by using the traction rope 23, so that the jacking and curing device 36 reaches the large deformation part 51.

[0051] ​S5: The external controller 42 transmits a signal to the internal controller 41 to activate jacks A364 and B373, causing the jacking platform 361 and the counter-support platform 371 to rise simultaneously. Because the protrusion 365 on the jacking platform 361 engages with the protrusion A355 on the coating platform 351, the coating platform 351 rises together under the elastic force of spring B353. Similarly, the cutting platform 381 rises together under the elastic force of spring C384. The jacks A364 and B373 lift the jacking platform 361, so that the carbon-glass hybrid woven fabric 31 is pressed against the large deformation part 51 under the action of the lifting block A362. Driven by the pressure, the large deformation part 51 is depressed and restored. The jacks A364 and B373 are closed.

[0052] S6: The external controller 42 transmits a signal to the internal controller 41 to activate the UV curing lamp 363. Under the UV light, the light-curing resin on the carbon-glass hybrid woven fabric 31 is cured, forming a local reinforcement body on the inner wall of the large deformation area 51 of the pipe 5. After the strength of the reinforcement body reaches the required level, the UV curing lamp 363 is turned off.

[0053] S7: The external controller 42 transmits a signal to the internal controller 41 to activate jacks A 364 and B 373, causing the lifting platform 361 and the counter-support platform 371 to descend simultaneously, along with the coating platform 351 and the cutting platform 381. The entire device is then pulled within the pipeline 5 using the traction rope 23, allowing the cutting platform 381 to pass over the local reinforcement. The external controller 42 transmits a signal to the internal controller 41 to activate the electric slide 382, ​​causing the cutting blade 383 to slide along the electric slide 382 in an arc direction, cutting the carbon-glass blended woven fabric 31.

[0054] S8: The external controller 42 transmits a signal to the internal controller 41 to activate the rear camera 310, and the entire device is pulled by the traction rope 23 to move within the pipe 5. The external controller 42 is used to observe the repaired state of the major deformed portion 51 of the pipe 5 in real time.

[0055] S9: Repeat the above steps until the entire pipeline 5 is repaired.

[0056] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
