Abstract

The invention discloses an inflatable and extensible water retaining device for underground first-aid repair. The inflatable and extensible water retaining device comprises a water retaining plate A,a water retaining plate B, a housing water retaining plate, a pneumatic extensible cavity, a water retaining bag and a well opening support, wherein plate A movable sliding rails are arranged at the upper portion and the lower portion of the water retaining plate A, rubber pads are arranged on the outer sides of the plate A movable sliding rails, symmetrical-side lock catches are arranged in the rubber pads, the upper and lower plate A movable sliding rails of the water retaining plate A respectively act in slideways in the plate B, plate B movable sliding rails are arranged at the upper portion and the lower portion of the water retaining plate B, and the plate B movable sliding rails arranged at the upper portion and the lower portion of the water retaining plate B respectively act in slideways in the housing. The problem can be effectively solved that water flow in a pipeline cannot be effectively discharged out and is blocked during damaged pipeline maintaining operation, the device can be repeatedly utilized, the device is put into a well when water flow in the well needs to be blocked, inflation is performed through an air delivery pipe to make the device stretch, passing water can be quickly blocked, then water draining is performed by using a water pump, and the risk existing in a limited operation space if workers go down to the well can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of underground emergency repair equipment, in particular to an inflatable telescopic water retaining device for underground emergency repair. Background technique [0002] With the development of the city, there are more and more underground water pipelines, and the pipeline repair tasks are also increasing. In the common pipeline repair technology in the society, sandbags are often used to fill the bottom of the inspection well upstream of the damaged pipeline to block the water flow. Personnel are required to go down the well to stack sandbags to form a limited space operation. The limited space operation requires a series of complex detection and exhaust work in the early stage, which has a great impact on the efficiency of pipeline repairs. cost, resulting in a waste of resources and manpower and material resources. [0003] Therefore, the present invention aims to propose an inflatable telescopic water...
