Leakage point distinguishing method and leakage stopping method for stirring pile waterproof curtain of foundation pit
The invention aims to provide a leakage point judgment method and leakage stoppage method for a stirring pile waterproof curtain of a foundation pit, and the method mainly comprises the following steps: at least one row of observation wells are arranged on the slope top of a side slope along the layout direction of the stirring pile waterproof curtain, and each observation well is located on one side, deviating from the side slope, of the stirring pile waterproof curtain; obtaining the water yield in each side slope downcast tube well arranged on the side slope, and determining a first target observation well according to the water yield; measuring and acquiring water level drop amplitude data in each observation well, and determining a second target observation well according to the water level drop amplitude data; and according to the first target observation well, the second target observation well and a preset rule, the leakage point of the stirring pile waterproof curtain is comprehensively judged. Compared with the prior art, the leakage point of the stirring pile waterproof curtain can be determined in a short time, and the judgment time of the leakage point of the stirring pile waterproof curtain is greatly shortened.
本申请的目的是提供一种用于基坑的搅拌桩止水帷幕的漏点判别方法及堵漏方法，其主要包括以下步骤:在边坡的坡顶上沿搅拌桩止水帷幕的布局方向至少设置一排观测井，并使得各观测井均位于搅拌桩止水帷幕背离边坡的一侧；获取设置于边坡上的各边坡降水管井内的出水量，并根据出水量确定第一目标观测井；测量并获取各观测井内部的水位下降幅度数据，并根据水位下降幅度数据确定第二目标观测井；根据第一目标观测井、第二目标观测井以及预设的规则综合判定搅拌桩止水帷幕的漏点。与现有技术相比，本申请可在较短时间内确定搅拌桩止水帷幕的渗漏点，极大地缩短了搅拌桩止水帷幕的渗漏点的判定时间。
