Water-swelling waterproof type maintenance water stop system

Abstract

The invention discloses a water-swelling waterproof type maintenance water stop system. The system structurally comprises a valve, a pipeline and a bifurcated water stop structure, the valve is installed at one end of the pipeline, the bifurcated water stop structure is installed at the other end of the pipeline, the bifurcated water stop structure is movably attached to the inner wall of the pipeline, and the bifurcated water stop structure is provided with a dual water stop structure and an opening and closing device; and the dual water stop structure is installed in the pipeline, the opening and closing device is located on the outer wall of the pipeline, and the opening and closing device is mechanically connected with the dual water stop structure. According to the system, by means ofthe design of the opening and closing device, the bifurcated water stop structure is installed in the pipeline, a movable rod is movably operated, a movable piece is unfolded outwards and attached tothe inner wall of the pipeline, fixing of equipment on the pipeline is achieved, and fixing is achieved; and the left lobe and the right lobe of a forked clamp are impacted to be separated left and right, so that the edges of the left lobe and the right lobe are tightly attached to the inner wall of the pipeline, the purpose of semi-closing the pipeline is achieved, and the impact effect of waterflow on an expansion closing structure is also reduced.

Description

technical field [0001] The invention relates to the field of water conservancy engineering, in particular to a water-swelling and water-repelling maintenance and water-stopping system. Background technique [0002] In the existing technology, if it is necessary to replace and maintain the soft packing water stop in water conservancy projects, the original water stop (such as packing) is usually removed first, and then a new water stop material is installed, and the original water stop is removed in time. After installing the new water-stop material, there will be a lot of water leakage and water spraying, and the water inlet pipe needs to be water-stopped. The existing technology uses water-expandable glue for water-proof expansion. This glue is more viscous than the inner wall of the pipe. Weak, vulnerable to water impact and cause collapse, poor water-stop effect. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention is re...
