Description
Technical Field
The invention belongs to the technical field of slope construction devices, and particularly relates to a slope supporting device and a slope supporting method.
Background
Due to the reasons of rock-soil body filling and digging, natural environment erosion and the like, a plurality of slope terrains can appear, and rock-soil bodies of the slope terrains can be damaged by deformation, movement and the like along with subsequent operations of environment, filling and digging and the like, and even have serious consequences of slope collapse, landslide, debris flow, vegetation damage and the like. To prevent these damages from occurring, the slopes need to be protected.
Common slope protection methods include vegetation protection, engineering protection, masonry protection and the like. The vegetation protection method is to plant grass or trees on a side slope to slow down the water flow speed on the side slope, and fix the surface soil of the side slope by using plant roots to reduce the washing of water to the surface soil. Engineering protection means that a special slope supporting device is fixed on a slope, and the method is suitable for soil which is not suitable for plant growth. The protection of the masonry stones refers to the fact that the masonry stones are fixed on the surface of the water-immersed side slope, and the stone materials can effectively resist long-time erosion and scouring of water due to strong water resistance and certain rigidity, and finally the side slope can be prevented from being damaged.
The slope supporting device in the method mainly comprises a gravity retaining wall, a buttress retaining wall, a cantilever type support, a plate rib type or lattice type anchor rod retaining wall support, a row pile type anchor rod retaining wall support and the like. The supporting body with the net-shaped structure is constructed on the side slope in the most common mode, the supporting body with the net-shaped structure is formed by splicing a plurality of supporting units, grid lines are used for fixing soil, rock and soil landslide loss is realized, vegetation can be planted in grids, and the ecological environment is improved. Although the supporting unit can fix soil, with the long-term natural environment erosion, the rock-soil mass on the side slope still has landslide and collapse conditions with smaller amplitude, for example, landslide or collapse with the thickness of 1-3cm occurs, and the stress direction of the rock-soil mass on the supporting unit structure also changes. The greater the change of the stress direction angle, the poorer the stability of the supporting unit, and the lower the protection effect. Therefore, it is necessary to develop a slope supporting device capable of generating adaptive micro-deformation according to small-amplitude landslide and collapse terrain changes so as to improve the protection effect of the slope supporting device.
