Embodiment 1
[0027] The working principle of the present invention will be further described below in conjunction with the accompanying drawings:
[0028] Such as figure 1 , figure 2 As shown, a device for detecting runoff position on karst slopes, which includes PVC pipe (DN25) 1, first three-way (DN25) 2A, second three-way (DN25) 2B (horizontal end is main pipe, vertical end is Branch pipe), first water storage pipe 3A, second water storage pipe 3B, first pipe cap (with hole) 4A, second pipe cap (with hole) 4B, first water guide pipe 5A, second water guide pipe 5B, first pipe Plug 6A, second tube plug 6B, fine gauze 7. The working principle of the present invention is: when the surface produces water, the water flow will enter the pipe through the hole drilled on the wall of the PVC pipe (DN25), and then divert to both sides, and flow into the first three-way (DN25) 2A, the second three-way ( DN25) 2B main pipe, and then stored in the first water storage pipe 3A and the second water ...
Embodiment 2
[0031] A method for detecting runoff position on a karst slope, the steps of which are:
[0032] 1. Select points on the slope. Before burying the device, first select two typical transects that are basically symmetrical on the slope (the transect goes to the vertical contour line), divide them into slope positions such as the top, shoulder, back slope, foot of the slope, and depression, and then carry out Spot on the spot. The point selection follows the following two principles: First, according to the slope length of each slope position, the nodes at equal intervals along the slope are determined as the installation points. Due to the strong heterogeneity of the karst area, it is recommended to set the interval along the slope as 10 to 15m; on this basis, by increasing the number of installation points to ensure that the selected installation points basically include typical heterogeneous niche types such as soil surface, bare rock, stone trough, and stone crevice, and fin...
