Embodiment 1
[0017] Embodiment one: if figure 1 As shown, the underground diaphragm wall 1 is set in the foundation pit (the foundation pit is not shown). This embodiment is used to detect whether there is leakage on the wall of the underground diaphragm wall and the location and range of the leakage point.
[0018] The leakage detection method of underground diaphragm wall 1 in the present embodiment comprises the following steps:
[0019] 1) Layout hole position: such as figure 1 As shown, test holes A1-A4 and test holes B1-B4 are set up on the inner and outer sides of the foundation pit and within a certain range from both sides of the underground diaphragm wall 1 . The test holes A1-A4 and B1-B4 on the inner and outer sides of the foundation pit should be 1-2m away from the underground diaphragm wall respectively. effective detection. The connection line of the test hole A1-A4 and the connection line of the test hole B1-B4 are kept parallel to the underground diaphragm wall 1, and t...
Embodiment 2
[0024] Embodiment 2: Compared with Embodiment 1, this embodiment differs in that: figure 2 As shown, ion solution injection holes Y1 and Y2 are opened outside the foundation pit, and the ion solution injection holes Y1-Y2 are located outside the test holes A1-A3 outside the underground diaphragm wall 1 . Such as image 3 As shown, after the first detection work is completed, low-resistance ion solutions of appropriate concentrations are injected into the ion solution injection holes Y1 and Y2 respectively. Due to the difference in water pressure, the groundwater outside the foundation pit will flow into the foundation pit. If there is leakage in the underground diaphragm wall 1, the low-resistance ion solution injected into the ion solution injection holes Y1 and Y2 outside the foundation pit will pass through the seepage of the underground diaphragm wall 1. Leaks flow to the inside of the foundation pit. Then in "data processing and judgment", the resistivity profile detec...
