Leakage plugging device for water supply and drainage pipeline and its application method

Abstract

The invention discloses a water supply and drainage pipeline plugging device and a using method thereof, and belongs to the technical field of pipeline repair. The water supply and drainage pipeline plugging device comprises an inner clamping plate and an outer clamping plate which are separately clamped on the inner side and outer side of a pipeline correspondingly, and the inner clamping plate and the outer clamping plate are both bar plates of which the width edges are arcuate; a driving rod is hinged to the side, facing the outer clamping plate, of the inner clamping plate; a circular locating hole is formed in the alignment position between the outer clamping plate and the hinging position, and internally provided with a locating block, and the outside surface of the locating block and the inside surface of the locating hole are separately provided with external threads I and internal threads I matched with the external threads I correspondingly; a through hole for the driving rodto penetrate is formed in the locating block hollowly, and the inside surface of the through hole is provided with internal threads II of which the length and direction are the same as the length anddirection of the external threads I; and the outside surface of the driving rod is provided with external threads II matched with the internal threads II. According to the water supply and drainage pipeline plugging device, the complete and tight plugging effect can be achieved, and the application scope is wide; and the subsequent application value can be further improved, and the plugging device is ingenious in structure design, and easy to operate.

Description

technical field [0001] The invention relates to the technical field of pipeline repair, in particular to a water supply and drainage pipeline leakage plugging device and a use method thereof. Background technique [0002] In the process of urban development, water supply and drainage pipeline engineering plays an important role. Water supply and drainage pipeline engineering belongs to the basic construction of the city and is closely related to people's work and life. Residential buildings need to arrange water supply and drainage pipes. In some old residential buildings, the water supply and drainage pipes installed in residential buildings are arranged outside. Due to the age, the outside will be damaged by nature or man-made, and water leakage is prone to occur. This just needs to repair the pipeline of leakage, and generally, adopts leak-stopping device usually to block the leak to reach the purpose of stopping water leakage. [0003] At present, the existing leak plu...

Problems solved by technology

It has the following disadvantages: in reality, the leaking part of the pipeline is rarely a standard circular hole, and its shape is usually irregular, and more of it should be a crack structure, so it is difficult to directly and completely seal it with the plugging parts Due to the irregular structure of holes or cracks, after being used for a period of time after plugging, irregular holes or cracks are likely to deform and expand, and the plugging device will lose its plugging effect
