The use of reservoir bentonite waterproof blanket for grass protection during the construction period utilizes the interaction between anchor rods, anchor ingots, and reservoir bentonite waterproof blanket. The overall stress is fixed by planting soil and retaining it on the slope road surface. After the survival of the grass seeds and shrub seeds to be sprayed, they will mainly rely on them to lower the slope surface damage

1) The stems and leaves of vegetation can produce hydrological effects such as rainfall interception, weakening splash erosion, and inhibiting surface runoff. At the same time, the root system of herbaceous plants convolves and forms roots in the shallow soil of the slope surface. Geocomposite materials produce mechanical effects similar to reinforcement, thereby preventing shallow sliding of the soil and slope surface inside the reservoir's bentonite waterproof blanket;

2) The vertical roots of woody plants can penetrate deep layers and produce anchoring effects similar to full-length bonded anchor rods through the friction between the main and lateral roots and the surrounding rock mass. The horizontal roots of woody plants penetrate deep layers through fine cracks on the surface of the rock layer, creating a supporting mechanical effect. The comprehensive mechanical effect of the vertical and horizontal roots of woody plants prevents deep sliding of the slope.
