[0002] The concrete ecological slope protection is a slope protection technology of supporting a slope or a side slope by comprehensively using basic knowledge of engineering mechanics, soil science, ecology and botany, forming a comprehensive slope protection system composed of plants or engineering and plants. After the excavation of the side slope, the surface layer of the side slope is protected and reinforced by planting plants and utilizing the interaction (root anchoring effect) between the plants and the rock and soil body, so that the requirements for the stability of the surface layer of the side slope are met and the damaged natural ecological environment is restored. The concrete ecological slope protection is an effective slope protection and reinforcement means.

[0003] The existing concrete ecological slope protection is mostly directly paved with an ecological slope protection after paving a geotextile on the side slope, which easily leads to poor supporting effect of the bottom of the ecological slope protection, and the ecological slope protection collapses due to the difference caused by the slight subsidence of the soil of the side slope, which leads to the damage of the side slope.
