Description

Slope unloading stable structure Technical Field The utility model belongs to the technical field of slope reinforcement, and particularly relates to a slope unloading stabilizing structure. Background In slope engineering, unloading is one of the important factors that cause instability of the slope. The unloading effect is usually caused by side slope excavation, underground water level change or natural factors, and the like, and can cause the stress state of the side slope rock-soil body to change, so that deformation and damage are generated. The unloading effect can cause the internal stress of the rock mass near the unloading surface to be redistributed, can cause local stress concentration, can cause the surface rock mass to rebound during unloading, and can form a constrained residual stress system in the rock mass due to differential rebound. Deformation and fracture of the rock mass during unloading is caused by the change of the stress state of the rock mass. For a side slope, the unloading effect generally causes instability of the side slope, and the problems of slope sliding and the like are generated. And a construction structure for improving the overall stability of the slope after unloading is required to be developed and designed, so that the slope stability is improved. Disclosure of utility model The utility model aims to provide a slope unloading stable structure which improves the overall stability of a slope after unloading. The side slope unloading stabilizing structure comprises a reticular frame type stabilizing platform constructed on a side slope surface, wherein the reticular frame type stabilizing platform is formed by splicing cross type stabilizing platforms, the cross type stabilizing platform is formed by casting concrete in situ in a cross type cast-in-place groove formed on the side slope surface, connecting ribs are arranged between adjacent end parts of adjacent cross type stabilizing platforms, one end of each connecting rib is cast and formed at the end part of one cross type stabilizing platform, the other end of each connecting rib is cast and formed at the end part of the other cross type stabilizing platform, grouting type prestressed anchor cables are arranged in the side slope surface positioned at the inner side of each cross type stabilizing platform in a beating mode, a center buttress is cast and formed at the center position of each cross type stabilizing platform, and anchor pads of the grouting type prestressed anchor cables are cast and formed in the center buttress in an integral mode. Preferably, a top water interception ditch is formed at the top of the slope surface in a cast-in-situ mode, the top water interception ditch comprises a horizontal section, a water retaining wall is arranged in the middle of the horizontal section, a first inclined section extending downwards along the slope surface is arranged at one end of the horizontal section, and a second inclined section extending obliquely upwards is arranged at the other end of the horizontal section. Preferably, a cast-in-situ formed top combination body is arranged between the end part of the uppermost cross-shaped stable platform and the first inclined section of the top intercepting ditch on the slope surface of the side slope, and a cast-in-situ formed bottom extension body is arranged between the end part of the lowermost cross-shaped stable platform and the slope bottom on the slope surface of the side slope.
