Abstract

The invention discloses a protective greening structure for a rock or concrete high and steep slope and a construction method of the protective greening structure. The structure comprises an upper protective structure and a lower protective structure arranged on the surface of the slope. The lower protective structure comprises a plurality of ecological bags which are sequentially stacked up along the slope bevel, the ecological bags are filled with planting soil mixed with compound fertilizer, the surfaces of the ecological bags are covered with an iron gauze, the iron gauze is fixed through a plurality of anchor rods inserted into the slope, and the surfaces of the ecological bags are coated with a layer of ecological base material. The upper protective structure comprises a green cover geonet covering the slope surface, and the green cover geonet is fixed through fixing nails. Climbing plants are planted on a planting platform formed by the ecological bags on the topmost portion of the lower protective structure. The protective greening structure can effectively solve the problems that when the rock slope or the concrete high and steep slope is protected at present, the water retention capacity is poor, drought enduring cannot be achieved, the supplying capability is poor, construction is complex, the construction period is long, landslide hidden dangers exist and the cost is high.

Description

technical field [0001] The invention relates to the technical field of slope greening protection, in particular to a rock or concrete high and steep slope protective greening structure and a construction method thereof. Background technique [0002] At present, slopes are generally protected by concrete. For slopes protected by concrete, although the problem of soil erosion can be solved, large areas covered with sand and gravel materials will easily cause visual incongruity, which is not conducive to greening and ecological protection requirements. For the rock slope after excavation, if no greening protection is carried out, it will not only cause visual pollution, but also cause further differentiation of rock mass, thus causing natural disasters. At present, the greening methods for rocky slopes or concrete high and steep slopes are mainly spray greening of ecological substrates, greening of planting troughs with floating boards, greening of climbing plants and greening ...
