Abstract

The invention discloses a pipeline leaking blocking and isolation repairing method. The method is carried out on the basis of a novel blocking device, wherein the blocking device mainly comprises two spiral driving units and two blocking repairing units, wherein one spiral driving unit and one blocking repairing unit form a blocking repairing system set; each blocking repairing unit comprises a supporting frame, a blocking air bag, a repairing air bag and a metal coating layer; and the spiral driving units comprise front driving systems, outer rotor motors and rear supporting systems. In case of leaking accident of a pipeline, three conditions, including a single-point leaking condition, a short-spacing multi-point area leaking condition and a multi-point long-spacing dispersing section leaking condition based on the pipeline leaking condition. According to the method, the blocking repairing units are dragged into a leaking area through the spiral driving units; and the pipeline leakage is subjected to emergency treatment by blocking and isolation mending repairing and blocking and isolation replacing repairing based on the leaking condition.

Description

technical field [0001] The invention belongs to the technical field of pipeline plugging, and in particular relates to a novel pipeline sealing device and a method for sealing, isolating and repairing pipeline leakage based on the novel pipeline sealing device. Background technique [0002] With the rapid development of the global energy landscape, pipeline transportation has increasingly become an important transportation route. Due to the increase in the service life, natural damage, human interference or fluid corrosion and other factors, it is easy to cause leakage phenomena such as cracks or damage in the pipeline. If the leaking pipeline cannot be treated in time, once an accident occurs, it will cause serious damage. economic losses and environmental pollution, and even threaten the lives of the people. Currently, there is no plugging device for pipeline leakage on the market, and there is no such plugging and repairing method. This technology proposes an emergency s...
