A positioning device 3 corresponding to the multiple drainage pipes 2 is provided at the slope of the seepage interception dam 1. The positioning device 3 fixes the end of the multiple drainage pipes 2 that they converge to avoid displacement of the drainage pipes 2 caused by changes in ground stress or settlement inside the seepage interception dam 1. The positioning device 3 is a strip structure extending along the same horizontal line of the seepage interception dam 1, with multiple positioning notches 5 in its length direction. Generally, the positioning device 3 is strip-shaped or square, or if multiple layers of drainage pipes 2 are set, two or more positioning devices 3 can be spliced ​​together.
