Technical Field

[0001] The invention relates to the technical field of municipal engineering, and in particular to a rapid repair device and method for damaged underground drainage pipes. Background Art

[0002] In the development process of modern cities, drainage pipe networks, as an indispensable and important part of urban drainage systems, undertake the key task of rainwater and sewage discharge. With the expansion of urban scale and the increase in drainage demand, the scale and complexity of drainage pipe networks are also increasing. However, various factors in the long-term operation process, such as soil erosion, foundation settlement, pipeline aging, etc., will cause structural or functional defects in the drainage network, such as damage and collapse. These defects will not only reduce the water flow capacity of the pipeline, but may also cause a series of serious problems, such as urban waterlogging, black and smelly water pollution, surface collapse, etc., posing a major threat to the city's environment, traffic safety, and the safety of life and property of residents.

[0003] Traditional drainage network defect treatment methods have many shortcomings, such as long treatment cycle, low efficiency, high cost, etc., and it is difficult to quickly respond to pipeline damage problems in emergency situations. Therefore, how to quickly and efficiently solve the problem of underground drainage pipe damage has become a major challenge in the current operation and maintenance management of urban drainage systems.

[0006] Furthermore, the metal bracket is initially in a folded state, and its diameter is smaller than that of the pipe.

[0007] Furthermore, the elastic rubber sleeve is arranged on the outside of the metal bracket and fits with the metal bracket.

[0008] Furthermore, the metal bracket has a self-locking mechanism, and when the metal bracket is fully expanded, the self-locking mechanism locks the metal bracket.

[0010] Furthermore, in the step 2, the pipeline robot is first connected to the repair equipment, and then the pipeline robot and the repair equipment are lowered into the pipeline together from the inspection well.

[0011] Furthermore, in step 4, after the stent is expanded into place, the balloon is continuously pressurized so that the elastic rubber sleeve is fully fitted to the inner wall of the pipe.

[0012] The invention discloses a rapid repair device and method for a damaged underground drainage pipe, and its beneficial effects include: Fast and efficient: Through the coordinated use of pipeline robots and drainage network defect databases, rapid identification and positioning of pipeline damage defects are achieved. Combined with the rapid installation of pipeline supports, the speed of handling pipeline defects is significantly improved, and the normal operation of the pipeline can be restored in a short time.

[0013] Strong anti-scouring performance: The adopted pipe support has good anti-scouring performance, can maintain stable support under harsh water flow conditions, and effectively prevent the pipe from being damaged or collapsed again.

[0014] Green and environmentally friendly: The entire disposal process does not require large-scale excavation and backfilling, which reduces damage and pollution to the surrounding environment and is in line with the concept of green development in modern cities.

[0015] Wide scope of application: This method is not only suitable for conventional drainage pipe damage treatment, but can also be widely used in water pollution control, water ecological environment protection, drainage emergency rescue and other projects, with high practical value and promotion prospects.
