Problems solved by technology
[0002] Because a large amount of spoil accumulation will be generated in many engineering constructions, and the accumulation of spoil is too high to easily lead to local collapse. The traditional support method is often to passively bear the load generated by the collapsed rock mass and soil, so the traditional support is easily affected. The damage to the collapsed rock mass and soil will bring many safety hazards in the long run

Embodiment Construction
[0020] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0021] Such as figure 1 , 2 As shown, the soil slope reinforcement structure includes a bottom reinforcement layer 1 and a vegetation layer 2 from bottom to top along the slope. , the reinforcement assembly includes cast-in-situ pile 4, cement layer 5 on the top of cast-in-place pile 4, a steel backing plate 6 located on the water-facing side of the cement layer 5 and inside the cement layer, and one end is fixed to the steel backing plate The other end of the top 6 is fixed to the anchor cable 7 buried inside the slope, and the upper and lower ends of the steel backing plate 6 have reinforcement rods 61 extending obliquely downward towards the cast-in-place pile.
[0022] The included angle between the anchor cable 7 and the cast-in-place pile 4 is 80-30°, preferably 70°. The end of the anchor cable 7 connected to the steel backing plat...

The invention discloses an earth slope reinforcing structure and method. The structure comprises a bottom reinforcing layer and a vegetation layer from bottom to top in sequence along a slope. The bottom reinforcing layer comprises a crown beam on the lowest layer and a reinforcing assembly arranged above the crown beam. The reinforcing assembly comprises filling piles, cement layers arranged at the tops of the filling piles, steel shims arranged on the sides of upstream faces of the cement layers and located inside the cement layers, and anchor cables with one ends fixed to the steel shims and the other ends fixedly buried inside the slope. By adopting the structure, the earth slope reinforcing structure and method have the following advantages that firstly, an anchor cable construction machine and equipment have small requirements for the working space and are suitable for various terrains; secondly, disturbance to a soil body is small, and deformation of the soil body can be effectively controlled after prestressing force is applied; thirdly, the position, direction, space, density and the like of the anchor cables can be flexibly adjusted according to needs; and fourthly, the prestressing force applied to the anchor cables can be determined according to tests, and it can be guaranteed that sufficient safety is designed.
Description
technical field [0001] The invention relates to a soil slope reinforcement structure and method. Background technique [0002] Because a large amount of spoil accumulation will be generated in many engineering constructions, and the accumulation of spoil is too high to easily lead to local collapse. The traditional support method is often to passively bear the load generated by the collapsed rock mass and soil, so the traditional support is easily affected. The damage of the collapsed rock mass soil will bring many safety hazards in the long run. Contents of the invention [0003] The technical problem to be solved in the present invention is to propose a soil slope reinforcement structure that can actively reinforce the soil body, effectively prevent soil deformation, and further prevent collapse accidents. [0004] In order to solve the above-mentioned technical problems, the present invention provides a soil slope reinforcement structure, which sequentially includes a ...
