Quick processing device for large-flow water leakage hole in concrete body

Abstract

A quick processing device for a large-flow water leakage hole in a concrete body comprises a water drainage pipe installed at an opening of the water leakage hole, a ball valve installed at an outlet of the water drainage pipe, a long grouting pipe and a short grouting pipe, wherein the long grouting pipe and the short grouting pipe are welded to the inside of the water drainage pipe, the unwelded end, of a certain length, of the long grouting pipe extends into the water leakage hole, and the unwelded end of the short grouting pipe extends into the water drainage pipe. According to the quick processing device for the large-flow water leakage hole in the concrete body, the ball valve on the water drainage pipe is quickly closed, grouting is carried out through the short grouting pipe, the long grouting pipe is used for draining water, when slurry comes out from the long grouting pipe, the long grouting pipe and the short grouting pipe are simultaneously used for grouting, the two pipes are in parallel connection for grouting, and the anti-leakage aim is achieved. In the early stage of grouting, the long grouting pipe can be used for draining water all the time so that pressure of water in the water leakage hole cannot be excessively high and grouting cannot be influenced; according to the quick processing device, the processing principle that plugging is carried out during drainage and drainage is carried out during plugging is adopted, and the aim of quickly plugging the water leakage hole is achieved; the quick processing device is easy to manufacture and install and convenient to operate; the device is simple, practical and good in effect when the large-flow water leakage hole is processed.

Description

technical field [0001] The invention relates to a water leakage treatment device, in particular to a device for quickly treating large-flow leakage holes in a concrete body. Background technique [0002] In the construction of hydropower concrete dams, in order to meet the diversion during the construction period of the dam, temporary diversion holes or diversion holes are often set up at the bottom of the dam for diversion. The water is temporarily blocked by diversion holes (holes). After the lower sluice is impounded, the water pressure of the upstream reservoir rises, and under the action of high water pressure, water leakage occurs in the parts with weak construction quality in the diversion hole (hole), and some parts even have a large flow of water leakage. In order to meet the diversion bottom hole (hole) ) plugging and dam body safety, the leaking parts must be plugged as soon as possible. Because of the high water pressure, fast flow rate, and large water volume ...
