Underground pipeline repairing system and method

Abstract

The invention relates to an underground pipeline repairing system and method. The underground pipeline repairing system is composed of a pipeline repairing supporting framework body, a repairer driving device, a repair device, an operation control device, a pipeline positioning camera, a main supporting frame, a positioning instrument, a controller and a battery pack. The main supporting frame is a cylindrical framework overall, the pipeline positioning camera is arranged at the front end of the main supporting frame, the positioning instrument, the battery pack and the controller are arranged in the middle of the main supporting frame, and the controller is connected with a driver, the pipeline positioning camera and the positioning instrument through circuits. The repair device is installed on the main supporting frame. A pipeline repair air bag is arranged in a positioning barrel and expands when inflated for a pipeline to be repaired, the positioning barrel and a gel adsorption layer fixing belt expands as well until the positioning barrel and the gel adsorption layer are attached to the pipeline to be repaired. The underground pipeline repairing system and method are scientific in design, reasonable in structure, convenient to construct and low in manufacturing cost. A repairer does not need to enter the pipeline and carries out remote control operation on the ground. The repairing portion of the pipeline to be repaired is accurately observed and positioned. The underground pipeline repairing system and method can be applied and popularized in the urban water conveying pipeline repairing engineering, and has broad market prospects.

Description

technical field [0001] The invention relates to an underground pipeline repairing device, in particular to an underground pipeline repairing system and an underground pipeline repairing method. Background technique [0002] Many pipelines buried underground are intersected and intricate. Some pipelines have been used for many years, and leakage and rupture accidents frequently occur. Most of these pipelines are laid in densely populated and commercially prosperous urban areas. Excavation construction will cause traffic Blockage, destruction of green spaces and gardens, and the process of excavating and repairing pipelines often cause damage to other pipelines. Some pipelines have small diameters and no working surfaces, so personnel cannot enter the pipelines to carry out repairs. There is another fatal problem with the pipelines in the city. Most of the underground pipelines are airtight, and there is a lot of deadly poisonous gas, and people cannot enter the pipeline netwo...
