Description

Technical Field

[0001] The invention relates to the technical field of underwater gate leakage plugging, and in particular to an underwater gate leakage plugging method. Background Art

[0002] In the application of gates, as the gates are used for a longer time, local cracks and leakages are prone to occur. In order to ensure the normal operation of the gates, manual plugging is required. Grouting plugging is currently a common plugging method. However, grouting plugging still has the following problems: it is difficult to judge the internal grouting situation when grouting directly through the grouting hole, and the problem of insufficient grouting may occur. When grouting a single grouting hole, impurities and foreign matter may exist at the leakage point, which may easily cause channel blockage and affect the grouting effect.

[0003] After searching, the Chinese patent application number CN202111221193.X discloses an asphalt grouting anti-seepage plugging method. The anti-seepage process of the asphalt grouting anti-seepage plugging method is to heat the asphalt in an asphalt melting furnace. When the temperature reaches the temperature range of 204℃-260℃, the asphalt begins to melt. The asphalt solution is obtained by melting for 30min-50min. Sand particles with a diameter of 2mm-5mm and a content of 50%-70% are added to the asphalt solution for mixing and stirring. The mixture is stirred for 5m. in-10min, obtain asphalt mixture 1, add 10%-20% polyurethane to asphalt mixture 1, stir and mix for 3min-5min, obtain asphalt mixture 2, add 5%-10% acrylic acid emulsion to asphalt mixture 2, stir and mix for 2min-5min, obtain asphalt anti-seepage material, pour the asphalt anti-seepage material into a high-pressure grouting machine, use the high-pressure grouting machine to pour the asphalt anti-seepage material on the base surface that needs to be anti-seepage, use a mud plate to smooth the asphalt anti-seepage material, and let it dry naturally for 2-3 days. The plugging method in the above patent has the following shortcomings: during grouting, it is difficult to judge the internal grouting situation, and the problem of insufficient grouting is likely to occur. When grouting a single slurry hole, due to the possible presence of impurities, foreign matter, etc. at the leaking site, it is easy to cause channel blockage, affecting the grouting effect.
