High-steep bare rock slope surface vegetation greening system and construction method thereof

Abstract

The invention discloses a high-steep bare rock slope surface vegetation greening system and a construction method thereof. The system comprises a roughening layer, a transition combination layer, an artificial soil layer, a plant seed layer and a protection layer which are sequentially arranged from bottom to top. By close attachment and combination of the toughening layer, the transition combination layer, the artificial soil layer and the protection layer, a complete vegetation greening system is formed, supply of water and nutrients of a nutrient layer and a plant growth layer suitable fordevelopment of plant root systems is established, so that rock surfaces are firm, the life of the high-steep bare rock slope surface vegetation greening system is prolonged, after several years, plantroot systems are firmly and densely anchored in all layers, and dual functions of greening and slope protection are realized; the problem about the life of the vegetation greening system is solved, rare rock surfaces and artificial soil are combined into a whole by pervious concrete intermediates, slipping of the artificial soil layer from the vegetation greening layer is prevented, and the service life of the vegetation greening system is greatly prolonged.

Description

technical field

[0001] The invention belongs to the field of environmental management of high and steep bare rock slopes, in particular to a greening system and a construction method for high and steep bare rock slopes. Background technique

[0002] At present, a large number of abandoned open-pit quarries, roads and railways that cut and dig mountains form a large number of steep rock slopes or rock walls with a slope of 40°-70° of exposed rock, and the natural conditions are very harsh. Cutting and digging the mountain makes the stability of the slope weak; the topsoil and nutrients needed for vegetation growth are seriously lacking, and the rocky slope does not have the soil environment necessary for vegetation growth. The external force erosion on the slope surface is mainly runoff erosion. Greening is very difficult. At the same time, the stability of the slope is drastically reduced, and natural disasters such as falling blocks and debris flows are prone to occur, whi...
