Method for repairing seepage damage of impervious wall of concrete faced rockfill dam
The invention provides a method for repairing seepage diseases of an anti-seepage wall of a concrete faced rockfill dam, and belongs to the technical field of repairing of anti-seepage walls of concrete faced rockfill dams The method comprises the steps that the range of the seepage diseases of the anti-seepage wall is delimited; grouting hole positions are arranged; setting the bottom elevation of the grouting hole; grouting holes are drilled in the grouting hole sites, preparation work of repairing grouting is completed, and then a water pressing test of the grouting holes is carried out; a grouting material is adopted for repairing and grouting; judging whether diaphragm wall joint leakage exists at the grouting hole or not; surrounding grouting holes are formed; the surrounding grouting holes are grouted, and leakage channels around the grouting holes are blocked and protected; after grouting of the surrounding grouting hole is completed, the grouting hole continues to be grouted; and repairing and grouting are conducted on the remaining impervious wall joints. According to the method, the leakage disease position is determined by observing the grouting pressure, and the repair grouting efficiency is improved; and a channel surrounding the grouting hole to block slurry loss is arranged at the joint part of the diaphragm wall with leakage diseases, so that the repair efficiency is improved.
本发明提供了一种面板坝防渗墙渗漏病害修复方法，属于面板坝防渗墙修复技术领域，本方法包括划定防渗墙渗漏病害的范围；设置灌浆孔位；设置灌浆孔的底高程；在灌浆孔位开钻灌浆孔，完成修复灌浆的准备工作，然后开展灌浆孔的压水试验；采用灌浆材料进行修复灌浆；判断该灌浆孔处是否存在防渗墙接缝渗漏；开设包围灌浆孔；对包围灌浆孔进行灌浆，对灌浆孔周边的渗漏通道进行封堵保护；完成对包围灌浆孔的灌浆后，对灌浆孔继续灌浆;对剩余防渗墙接缝进行修复灌浆。本方法通过观测灌浆压力确定渗漏病害位置，提高了修复灌浆效率；在存在渗漏病害的防渗墙接缝部位，设置包围灌浆孔以隔断浆液流失的通道，提高修复效率。
