Soil nailing and grass planting slope protection structure system on high and steep slopes and its construction method

Abstract

A soil nailing and grass planting slope protection structure system for high and steep slopes, including a planting layer, soil nail reinforcement, a vegetation board and a metal mesh; Segment surface; metal mesh and planting layer are laid on each section surface, and the metal mesh and planting board fix the planting layer through soil nail reinforcement; the metal mesh and planting layer, planting board and soil nail reinforcement work together to form a solidified 1. High and steep slope soil nailing and grass planting slope protection structural system for beautifying rock and soil slopes; the technological process of its construction method is: construction preparation → construction of the first row of soil nail reinforcement → installation of the first row of planting boards → installation of the remaining soil nails, Vegetation board → monitoring point layout → laying metal mesh → laying planting layer → covering non-woven fabric → maintenance and care. The structural system is simple; the construction period is short, the labor input is small, and it is economical and applicable; the construction on the steep slope does not require scaffolding operations, and the safety rope is used for protection and the planting board is used as the stepping point, so the safety factor is high.

Description

technical field [0001] The invention relates to a high and steep slope protection and greening structure system and a construction method thereof, in particular to a high and steep slope soil nailing and grass protection structure system and a construction method thereof. Background technique [0002] On construction sites on both sides of new roads and railways, in order to protect the original natural waters and vegetation in the site and maintain earthwork balance, slope greening method is often used to excavate and open slopes on both sides of the road. [0003] At present, the "framed soil greening method" is widely used for earthwork slope support (see 11-1~ Figure 11-2 ); the slope support technology is: on the steep rock slope surface, use engineering bolts to fix and reinforced concrete beams to form planting grooves, and plant trees, shrubs and climbing vines on the planting soil in the grooves. The process flow is: setting up scaffolding → forming holes with anch...

Problems solved by technology

[0006] This method uses large-diameter anchor rods and metal mesh to build a stable internal structural stress system on the slope soil, and sprays a green concrete protection system on the slope surface. The two systems work together to protect each other and reinforce the slope; Excessive use and covering of concrete will pollute the environment to a certain extent, which is not conducive to the natural water cycle; it is not material-saving; plants can no longer be planted after covering the concrete, artificially reducing the vegetation area and reducing the quality of perception
