Grouting processing method for stopping water leakage of underwater concrete

Abstract

The invention relates to underwater concrete pouring construction, in particular to a grouting processing method for stopping water leakage of underwater concrete. The grouting processing method includes steps of firstly, processing various water outlet points and leading out the water outlet points by steel tubes with valves; secondly, sequentially performing water pressure tests for the various water outlet points by the aid of colored water, testing distribution of water leakage channels and communication conditions of the water leakage channels and dividing the water leakage channels into a category of communicated water leakage channels and a category of independent water leakage channels; thirdly, judging an optimal grouting path via test results; fourthly, arranging for practical grouting according to the optimal path; and fifthly, performing grouting to block the water leakage channels. The grouting processing method for stopping water leakage of the underwater concrete has the advantages that the tests are performed before grouting, each water leakage channel can be compactly blocked basically, the processing quality is guaranteed, a construction principle is simple, operation is simple and convenient, the grouting steps are reasonable, the construction period can be effectively saved, the water leakage channels can be effectively blocked, and a processing effect can be guaranteed for main concrete.

Description

technical field [0001] The invention relates to underwater concrete pouring construction, in particular to a grouting treatment method for underwater concrete seepage plugging. Background technique [0002] At present, in the process of pouring underwater concrete, there are occasional water seepage accidents, and the treatment methods for each accident are different. If the water seepage is small, it is usually directly blocked by high-strength materials such as grouting materials, or the water is concentrated with steel pipes. Draw out the pouring range so that it does not affect the pouring of the upper concrete, and then after the pouring of the upper concrete is completed, press grout into the steel pipe to seal. However, when the amount of seepage is large, it is difficult to deal with it. Usually, special and complicated construction techniques are required to deal with it. The operation is cumbersome and the construction period is increased. Contents of the inventi...
