Spray-sowing slope protection structure for steep rock side slope

Abstract

The invention discloses a spray-sowing slope protection structure for a steep rock side slope. The spray-sowing slope protection structure is composed of a supporting reinforcing assembly and planting matrix, wherein the supporting reinforcing assembly comprises a galvanized iron wire mesh, planting strips, an active protective net and an anchor rod; the galvanized iron wire mesh is suspended on the slope surface of a side slope; the planting strips are long-strip bags which are sewn by non-woven fabrics, and planting soil mixed with a fertilizer are contained in the long-strip bags; the long-strip bags are alternated and horizontally arranged along the slope surface, and are tied on the galvanized iron wire mesh by iron wires; the active protective net is laid and suspended outside the planting strips; and the active protective net is fixed on the slope surface by virtue of the anchor rod. The planting matrix is a mixture of soil, organic substances, a binder, a fertilizer, a water-retaining agent, a PH regulator and plant seeds, is prepared by uniformly stirring the mixture, and is sprayed on the slope surface with the planting strips; and the planting matrix is 10 cm thick. A setting method for the slope protection structure comprises the following steps: renovating the slope surface, laying and hanging the galvanized iron wire mesh, laying the planting strips, laying and suspending the active protective net, and spraying the planting matrix. According to the spray-sowing slope protection structure, a side slope reinforcement and protection technology and a green protection technology are organically combined together to achieve the effects of preventing rockfall, guaranteeing side slope stability, afforestation and environmental protection.

Description

technical field [0001] The invention relates to slope protection technology, in particular to vegetation slope protection technology for rocky slopes. Background technique [0002] At present, with the increasing emphasis on environmental protection in my country, slope protection has developed from traditional masonry protection to ecological protection. As a new type of plant slope protection technology, spray-mixed vegetation is due to its good control effect and rapid restoration of greening ecology. It has been widely used due to the advantages of simple construction, economical and reasonable reinforcement measures, etc. The spray-mix planting technology is based on engineering mechanics and biology, using soil mixing adhesives and anchor rods to reinforce the hanging barbed wire technology, using special spray-mix machinery to mix soil, fertilizers, organic substances, water-retaining materials, sticky The mixed dry materials such as knot materials and plant seeds are...

Problems solved by technology

[0003] However, according to the requirements of the "Code for Design of Railway Subgrade" (TB10001-2005), the slope ratio of the spray-mixed vegetation is not steeper than 1:0.75, but in actual engineering, there are rocky slopes with a slope ratio steeper than 1:0.75 , even reaching the situation of 1:0.3

On such a steep slope, the sprayed substrate will slide down the slope under the action of gravity, and it is difficult to cover the steep slope. Therefore, for the steep rocky slope, the existing spray-mixed planting technology applications are limited
