Description

Technical Field

[0001] The utility model belongs to the technical field of slope protection, in particular to a slope ecological protection device used for water conservancy and hydropower engineering. Background Art

[0002] There are usually two ways to reinforce rock slopes: shallow reinforcement (hanging protective nets, sprayed concrete, anchor rods, frame beams, etc.) and deep reinforcement (anchor cables, etc.). Shallow reinforcement mainly solves the problem of local block stability of the slope and prevents the sliding of the slope rock mass along the surface, while deep reinforcement is mainly used to deal with slopes with specific sliding structural surfaces, which can effectively improve the safety factor of slope sliding stability.

[0003] When the slope rock mass is weathered, unloaded significantly, the surrounding rock mass is fragmented and mosaic structure, and the rock mass integrity is poor, it will have the sliding characteristics of both soil slope and rock slope, that is, shallow sliding and overall sliding may occur. Therefore, the slope of water conservancy and hydropower projects belongs to permanent operating slopes, and the safety level of the slope is required to be high. It is necessary to solve the shallow stability and deep stability of the slope at the same time. The existing conventional treatment and support methods are difficult to solve the above problems. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a slope ecological protection device, which can solve the problem that the slope is prone to shallow sliding and overall sliding and has poor safety.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a slope ecological protection device, including a slope surface and a concrete frame cast on the slope surface, the concrete frame is provided with intersecting staggered nodes, the inner side of the staggered nodes is fixed with anchor steel bars, and the ends of the anchor steel bars are connected with prestressed anchor rods;

[0006] Two parallel grooves are opened near the slope foot on the foundation plane of the slope surface. Steel mesh is placed inside the grooves and concrete is poured to form a concrete pile foundation.

[0007] A slope foot retaining wall is built on the top of the concrete pile foundation, and the slope foot retaining wall and the concrete frame are cast in one piece.

[0008] Preferably, the concrete frame is formed by staggered horizontal frames and vertical frames, and the concrete frame is staggered to form a plurality of square-shaped structures.

[0009] Preferably, the square structure formed by staggered concrete frames is paved with fish scale stones and planted with grass seeds.

[0010] Preferably, one end of the prestressed anchor rod is buried in the rock and soil layer through cement mortar, and the other end of the prestressed anchor rod is fixed to the staggered node through an anchor steel bar.

[0011] Preferably, a drainage ditch is opened in the middle of the retaining wall at the foot of the slope, and the drainage ditch and the cross-section of the retaining walls at the foot of the slope on both sides are in a "concave" structure.

[0012] The slope ecological protection device provided by the utility model has the following beneficial effects:

[0013] 1. By opening two parallel grooves at the foot of the slope, placing steel mesh inside the grooves and pouring concrete to form a concrete pile foundation, and setting up a foot retaining wall on the top of the concrete pile foundation, it can effectively prevent soil landslides, especially for the reinforcement of backfill slopes. The effect is more obvious, which can effectively protect the stability of the slope and the safety of the surrounding environment. In addition, by opening a downward-sunken drainage ditch in the middle of the foot retaining wall, rainwater in the infiltrating soil or water in the slope can be quickly drained away, avoiding groundwater infiltration and damaging the high slope reinforcement structure, and avoiding slope collapse accidents due to rainwater.

[0014] 2. By integrally casting the retaining wall at the foot of the slope and the concrete frame, the slope structure is made more stable. The setting of the concrete frame can make the shallow surface of the slope more stable, and the prestressed anchor rods fixed by anchor steel bars at the internal staggered nodes of the concrete frame can solve the deep sliding problem of the slope. One end of the prestressed anchor rod is buried in the rock and soil layer through cement mortar, and the other end of the prestressed anchor rod is fixed to the staggered node by anchor steel bars, which can give the concrete frame a force toward the inside of the slope, so that the concrete frame compacts the slope surface. Through the combination of the retaining wall at the foot of the slope, the concrete frame and the prestressed anchor rods, the broken rock slope forms a stable whole, and the reinforcement effect is better.
