Title:
METHOD FOR TREATING UNDERGROUND WATER DISASTER OF WEAK-PERMEABILITY SOIL LAYER SLOPE
Document Type and Number:
WIPO Patent Application WO/2023/173569
Kind Code:
A1
Abstract:
Disclosed in the present invention is a method for treating an underground water disaster of a weak-permeability soil layer slope. A three-dimensional seepage drainage system, a vacuum drainage aiding system, a self-flowing direct drainage system and a siphon drainage system are provided. The three-dimensional seepage drainage system comprises a horizontal seepage drainage shock tube (8), a vertical seepage drainage shock tube (17) and a water collection well (5). The vacuum drainage aiding system is composed of a vacuum pump (11) and a vacuum suction pipe (10). The direct drainage system comprises a water guide hole and a direct drainage pipe (21). The siphon drainage system comprises a deep well pump (12), a siphon pipe (15) and a siphon water supplementing pipe (13), wherein the deep well pump (12) is mounted at the bottom of the water collection well (5), a water input end of the siphon pipe (15) extends to a lower portion of the water collection well (5) along an inner wall of the water collection well (5), and the siphon pipe or the direct drainage pipe can automatically drain the water in the water collection well. By means of the present invention, smooth and centralized drainage of underground water of the weak-permeability soil layer slope can be effectively achieved, thereby preventing the saturation and erosion damage of the slope surface soil layer, and improving the lasting stability of the slope.
