Slope greening protection method and protection device
Technical Field
The invention belongs to the technical field of slope protection and greening, and particularly relates to a slope greening protection method and a slope greening protection device.
Background
In the construction of infrastructure such as roads, railways, hydropower and the like, a large number of slopes are often excavated. If the side slope is not protected and greened, a large amount of secondary bare land is often caused, and serious water and soil loss, shallow landslide and the like are generated. If the engineering side slope is covered by stones, concrete, building blocks and the like, although the shallow layer of the side slope can be reinforced, ecological damage and visual pollution are easily caused. The existing side slope protection generally adopts the mode that a protective net covers a side slope to prevent water and soil loss, and the protective net is easy to damage and loosen after the mode is used for a long time, so that the side slope originally covered with the protective net is exposed outside, and soil loss is easy to generate if the side slope is impacted by rainwater.
