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...

Embodiment 1

[0084] A soil nailing and grass planting slope protection structure system for high and steep slopes, comprising a planting layer 5 and a fixed structure for the planting layer. The solid 1 is fixed on the inclined surface of the rock-soil slope, and the slope is divided into n sections; each section is laid with a metal mesh 2 and a planting layer 5, and the metal mesh 2 and the planting board 3 are reinforced by soil nails 1 Fixed planting layer 5; metal mesh and planting layer, planting board and soil nail reinforcement work together to form a high and steep slope soil nailing grass planting slope protection structure system that can solidify, protect and beautify rock and soil slopes. The value range of n is: n Any integer between 2 and 1000; see figure 1 , figure 1 , there are 4 segments.

[0085] The soil nail reinforcement 1 is a soil hole 11 formed by a hole in the inclined surface of the slope, a soil nail reinforcement 12 anchored in the soil hole 11, a positioni...

Embodiment 2

[0089] A construction method for slope protection with soil nailing and grass planting on high and steep slopes. It is a construction method for forming the structural system of slope protection with soil nailing and grass planting on high and steep slopes described in Example 1. On the top, separate and segment artificially; lay metal mesh 2 and planting layer 5 on each partition surface, metal mesh 2 and planting board 3 fix the planting layer 5 through soil nail reinforcement; cover non-woven fabric 4 to protect vegetation during construction The metal mesh and the vegetation layer, the planting board and the soil nail reinforcement work together to form a high and steep slope soil nailing grass slope protection structure system that can solidify, protect and beautify the rock and soil slope (see figure 1 ); the technological process of its construction method is:

[0090] Construction preparation → construction of the first row of soil nail reinforcement → installation of...

Abstract

A soil nail grass-planting high abrupt slope protecting structural system comprises a planting layer, soil nail reinforcing bodies, planting boards and a metal screen. The planting boards are fixed to a diagonal plane of a rock-soil slope through the soil nail reinforcing bodies and divide the slope into a plurality of section surfaces; the metal screen and the planting layer are laid on the section surfaces, and the planting layer is fixed by the metal screen and the planting boards through the soil nail reinforcing bodies; through the combined action of the metal screen, the planting layer, the planting boards and the soil nail reinforcing bodies, the soil nail grass-planting high abrupt slope protecting structural system which can reinforce, protect and beautify the rock-soil slope is formed. A construction method of the structural system includes the technological processes of preparation of construction, construction of the first row of soil nail reinforcing bodies, installation of the first row of planting boards, sequential installation of the rest of soil nails and the planting boards, laying of monitoring points, laying of the metal screen, laying of the planting layer, covering of non-woven cloth and maintenance. The structural system is simple, short in construction period, low in labor investment and affordable; scaffold operation is not needed during construction on the abrupt slope, safety ropes are used for protection, and the planting boards are used as treading points, so that the safety coefficient 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...
