Description

Technical Field

[0001] The invention relates to the technical field of ultraviolet light curing pipeline repair, and in particular to a head binding device for airbag supported pipeline CIPP repair and a use method thereof. Background Art

[0002] Underground pipelines play an important role in urban infrastructure. They ensure the normal operation of the city and the convenience, safety and comfort of residents' lives. They constitute the "blood" and "nerves" of the city, providing reliable infrastructure support for the city's development. Therefore, the design, construction and maintenance of underground pipelines are of vital importance and need to be highly valued and scientifically managed. However, there are some problems and challenges in the current status of underground pipelines. As the use time of pipelines increases, the load on the ground and the corrosion inside the pipes will cause varying degrees of damage to the pipelines. For example, corrosion, fracture, leakage, etc. These problems have caused more serious problems such as road collapse, black and smelly water bodies, and urban waterlogging. This plan is formulated to accelerate the renovation of aging urban gas pipelines.

[0003] Trenchless technology has become an efficient and environmentally friendly solution for repairing pipelines without excavation. The solidification in place method (CIPP) is currently the most commonly used trenchless pipeline repair technology. In actual engineering, the tying of the tie head is crucial. Improper tying of the tie head may cause the inflation pressure to fail to meet the construction requirements, and the CIPP pipeline cannot fit tightly with the original pipeline, seriously affecting the quality of pipeline repair. However, the tying of the CIPP repair tie head for pipelines currently relies entirely on manual labor. The CIPP hose needs to be propped up manually, and then the tie head is inserted into the hose and tied with a professional tying rope. In this process, since the inner diameter of the CIPP hose is consistent with the outer diameter of the tie head, and the CIPP hose is heavy, it often requires 2-3 people to create, which is time-consuming and laborious, and often takes up more than 50% of the CIPP construction preparation time. Therefore, it is urgent to develop an efficient and convenient pipeline CIPP repair tie head tying device.

[0004] At present, there are also many patents in China to solve the difficulties of head binding. Patent No. CN113503421B discloses a head for UV curing repair of large-diameter pipes. The head can be assembled in parts and uses a soft cover plate, which reduces the weight of the original large-diameter pipe and is easy to carry. However, the head needs to be assembled underground, which is time-consuming and labor-intensive, and the small space in the inspection well makes operation inconvenient; Patent No. CN116834341A involves the field of construction management technology, providing a retractable head to avoid air leakage of UV-curing hoses during the curing process due to improper binding, but the retractable head involves the disassembly of the head during use, which adds another procedure to the original steps of head binding, which is time-consuming and labor-intensive; Patent No. CN216242953U provides a quick-installation UV-curing pipeline repair head to solve the problem of insufficient sealing during hose installation. The head is equipped with an installation adjustment module, which can assist in adjusting the hose so that the hose and the head fit tightly. However, the above patents only solve certain problems in the head tying process, such as the head being too heavy and the lack of airtightness, and the head tying steps are still cumbersome and inefficient.

[0005] In summary, the prior art obviously has inconveniences and defects in actual use. Therefore, it is necessary to provide an airbag-supported pipe CIPP repair head tying device and a method of use to solve the above technical problems. Summary of the invention
