Technical Field

The utility model relates to the field of ecological restoration, in particular to a soil-fixing water-retaining grid and an ecological slope protection.

Background

With the rapid development of economy in China, the construction of traffic roads such as roads and railways in various regions, the excavation of mines, and the construction of facilities such as villas in half mountains developed by land manufacturers destroy the ecological environment of mountains, a large number of exposed side slopes are formed, various environmental problems such as the damage of original earth surface vegetation, water and soil loss, debris flow and landslide are caused, and the exposed side slopes become topics which are concerned in the field of ecological restoration.

At present, the ecological restoration method for the slope with a large mountain slope mainly comprises the steps of covering soil on the slope toe, planting vines on the slope, maintaining green plants by adopting an embedded spray header, and utilizing the root systems of the green plants to fix soil. When the green plant on the bank protection was not full length completed, the bank protection mainly relied on the bank protection net soil stabilization, and soil stabilization ability is weak, and the soil of side slope will run off in a large number under heavy rain washes, causes the plant to lose growth space, and the plant survival rate is low, and then leads to the whole soil stabilization effect of bank protection poor.
