It is especially suitable for the environment with a large slope slope. It plays a supporting role for the blocks, and the blocks can be engaged with each other to increase the installation stability of the blocks. The clay mixture layer and grass seeds are filled in the holes of the blocks, and the clay mixture layer is loess and other soils. ; When the rainfall is too heavy, the seepage holes facilitate the drainage of the drainage sand cushion, and the second geotextile can prevent the water quality on the slope from being washed away with the rain.

The utility model is further configured as follows: the platform is inclined downward with an inclination angle of 1-2°, and a drainage groove facing the seepage hole is arranged on the downhill slope.

By adopting the above-mentioned technical solution, the platform is slightly inclined downward, which facilitates the water to drain downward and out, and at the same time, drains water through the drainage groove.

The utility model is further configured as: several water storage tanks placed under the drainage sand cushion are arranged on the uphill slope, and the water storage tanks have a stepped structure.

By adopting the above technical scheme, the uphill surface is designed as multiple steps, that is, the water storage tank has a stepped structure, and the water storage tank is also filled with drainage sand cushions. After precipitation, part of the water will remain in the water storage tank. When the weather is dry, The water storage tank can improve the moisturizing ability of the ecological slope protection, and at the same time, the drainage sand cushion has a certain humidity, which can also prevent its downward flow and accumulation.

The utility model is further configured as follows: the clamping block has a T-shaped structure.

By adopting the above technical scheme, the self-locking effect between the blocks is good, the structural stability is high, and the safety is good.
