The weathering and precipitation damages the surface of the side slope, which causes water and soil loss and side slope instability, and poses serious threats to the ecological environment and traffic safety. Therefore, it is necessary to take engineering measures to protect and restore the ecological function of soil.
At present, the common ecological slope protection forms include a soil engineering material composite planting base slope protection, a plant type slope protection, an ecological gabion slope protection, a vegetation type ecological concrete slope protection, an ecological bag slope protection, a porous structure slope protection, a self-embedded retaining wall slope protection and the like. The vegetation type ecological concrete slope protection is a novel material with the performance between that of common concrete and plowed and planted soil, and consists of porous concrete, a water retention material, a slow release fertilizer and surface soil. However, the alkali reduction treatment has problems, the strength and the durability of the alkali reduction treatment need to be verified, and the slope protection is expensive due to the fact that multiple times of soil covering and repeated sowing are needed. The porous structure slope protection is a slope protection for planting grass by using porous bricks, and common porous bricks comprise splayed bricks, hexagonal slope protection grid bricks and the like. The continuous penetration porous structure provides a good living space and a habitat for animals and plants, but the slope of the river bank cannot be too large, the river bank must be firm, soil needs to be compacted and compacted, the cost is high, and the construction workload is large.
