Problems solved by technology

[0004] 1. Excavation and repair of pipelines requires heavy workload and high economic costs;
[0005] 2. The natural repair in the non-excavation repair of the pipeline has a long repair time and low efficiency;
[0006] 3. The overall repair of ultraviolet light curing repair in pipeline trenchless repair is suitable for large-area pipeline damage, high cost and narrow scope of application;
[0007] 4. In the non-excavation repair of the pipeline, the point repair of ultraviolet light curing repair has a single repair control method and poor reliability

Embodiment 1

[0030] Embodiment one, as figure 1 As shown, a spot repair system for underground pipelines, including a host and repair airbags;

[0031] The main engine includes a power supply 1, an upper computer 2 and an air compressor 3, and the repair airbag includes an airbag body 4 and an airbag state detection equipment group 5 arranged on the airbag body 4 and an airbag state detection equipment group 5 arranged inside the airbag body 4. UV light frame 6, the outer wall of the airbag body 4 is coated with cured glue;

[0032] The power supply 1 is electrically connected to the upper computer 2, the air compressor 3, the airbag state detection equipment group 5 and the ultraviolet lamp frame 6 respectively, and the upper computer 2 is connected to the airbag state detection equipment respectively. The group 5 , the ultraviolet light frame 6 is connected in communication with the air compressor 3 , and the air compressor 3 is in communication with the air path inside the airbag body ...

Embodiment 2

[0055] Embodiment two, such as image 3 As shown, this embodiment also discloses a method for point repair of underground pipelines, using the point repair system for underground pipelines in Embodiment 1 to perform point repair, including the following steps:

[0056] S1: Place the repaired airbag at the position to be repaired in the underground pipeline, wait for the preset time after power on, and judge whether the upper computer 2 has received the airbag status data returned by the airbag status detection equipment group 5; if so, execute S2 to S5 in sequence ; If not, continue to wait;

[0057] S2: Use the upper computer 2 to input the repair pipe diameter selection command and lock it, and then input the inflation mode command;

[0058] S3: According to the inflation mode command, use the air compressor 3 to inflate the airbag body 4 until it is judged according to the airbag state data that the outer wall of the airbag body 4 is attached to the pipe wall of the underg...

Abstract

The present invention relates to an underground pipeline point repair method and its system. The system includes a host and a repair airbag; the host includes a power supply, a host computer and an air compressor, and the repair airbag includes an airbag body and an airbag state detection device arranged on the airbag body The equipment group and the ultraviolet lamp frame arranged inside the airbag body, the outer wall of the airbag body is provided with curing glue; It communicates with the airbag state detection equipment group, the ultraviolet light frame and the air compressor, and the air compressor communicates with the air circuit inside the airbag body. The present invention uses ultraviolet photocuring repair to carry out spot repair, and the repair time is short, the cost is low, the workload is small, and the efficiency is high. It is easy to realize pipeline repair and has high economic benefits.

Description

technical field [0001] The invention relates to the technical field of repairing underground pipelines, in particular to a spot repairing method for underground pipelines and a system thereof. Background technique [0002] With the rapid development of urban construction, underground pipelines continue to increase. However, it is known from pipeline construction and market adjustment that the underground pipelines in most cities often suffer from structural and functional damages, seriously affecting the lives of urban residents. Therefore, the research on the repair of underground pipelines is of great significance. [0003] At present, the repair methods for underground pipelines mainly include pipeline excavation repair and pipeline non-excavation repair, and pipeline non-excavation repair includes natural repair, overall repair of ultraviolet light curing repair and point of ultraviolet light curing repair. There are three repair methods. There are following deficienc...
