 In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
 see Figures 4 to 7 Shown, the water-stop curtain plugging method of the present invention may further comprise the steps:
 1) Ascertain the location of the leakage area 4 between the water-stop curtain 1 and the support pile 3. The leakage region 4 can be detected and located by special instruments in the prior art, such as groundwater detectors or leak listeners. In the embodiment of the present invention, several exploration holes 5 (the diameter of the exploration holes 5 can be about 10 cm) are drilled near the gap positions between adjacent support piles inside the foundation pit, and the rock core structure in the exploration holes 5 is obtained and compared with them. The degree of porosity, the explorator...
