Description

Technical Field

[0001] The utility model belongs to the technical field of rock slope protection, and in particular relates to a rock slope reinforcement device utilizing anchor rods. Background Art

[0002] The existing slope protection nets can be divided into active protection nets and passive protection nets. Passive protection consists of four main parts: wire rope nets, ring nets, fixing systems, pressure relief rings and steel columns. The steel columns and wire rope nets are connected and combined to form a whole, forming a surface protection for the protected area, thereby preventing the collapse of rock and soil and playing a role in slope protection. Active protection is a variety of flexible nets mainly based on wire rope nets, which are wrapped around the required protection slope or rock to limit the weathering, peeling or destruction of the rock and soil on the slope, or control the movement of falling rocks within a certain range.

[0003] In the existing slope protection nets, the connection method between the protection net and the slope is relatively simple. For example, the double-layer slope protection net disclosed in the publication number CN103374921A includes a main net body, which is made of multiple metal nets with the same shape and structure. The edge of the metal net is provided with a metal positioning hook. The lower surface of the main net body is provided with a secondary net body overlapping with it, and the secondary net body is made of a completely biodegradable material. In its technical solution, a metal positioning hook is provided on the edge of the metal net. When installed, it can be inserted into the slope or desert to play a fixing role. The technical solution realizes the connection with the slope by means of the positioning hook, so that the connection stability between the positioning hook and the slope is poor, and the positioning hook is easy to be separated from the slope, which is easy to cause the metal net to be unhooked due to insufficient grip after the rock soil falls off, which is not conducive to the protection of the slope.
