Stress steering device for anchor rope of protective net and mounting method of stress steering device

Abstract

The invention discloses a stress steering device for an anchor rope of a protective net. The device comprises a bottom plate which is fixedly attached to a slope surface, anchor rods, an arch ring anda limiting plate; one end of each fixed anchor rod is pre-buried in the slope surface fixed by the steel wire rope anchor, the other end of each fixed anchor rod is fixedly connected with the bottomplate, the bottom of the arc-shaped arch ring is fixedly connected with the front side and the rear side of the bottom plate, the steel wire rope anchor is bent to surround the arc-shaped edge of thearch ring, and the limiting plate is arranged at the top of the arch ring and allows the steel wire rope anchor to penetrate. By means of the scheme, the slope protection device has the advantages ofbeing simple in structure, convenient to install, reliable in fixation and the like, and has high practical value and promotional value in the technical field of slope protection.

Description

technical field [0001] The invention relates to the technical field of slope protection, in particular to a protective net anchor rope force steering device and an installation method thereof. Background technique [0002] As we all know, landslides and rockfalls are the most common types of geological disasters in mountainous areas, which have also caused huge economic losses and casualties; at present, there are many protective measures for landslides and rockfalls in the prior art. Among them, the protective net system is low in cost, It has many advantages such as simple and fast construction, strong ability to adapt to complex terrain, and environmental protection, and has been widely used in the fields of railways and highways. Such as Figure 1 to Figure 2 As shown, the protective net system is mainly composed of steel wire rope nets, ring nets or steel wire grids that intercept or guide the trajectory of falling rocks, steel columns that support stress, and anchor ro...

AI Technical Summary

Problems solved by technology

The best stress state of the wire rope anchor is that the external force is the same as the anchoring direction, but the rockfall area is often complex in terrain and the anchoring conditions are poor; construction difficulty

On the other hand, when the falling rock hits the protective net, the protective net system will be deformed, and the direction of the anchor rope will also change. At the same time, it will drive the exposed part of the wire rope anchor to bend at the anchor hole. In this way, the pulling force cannot be fully effective. will be transmitted to the anchorage section, and will squeeze the soil at the hole, causing the stress concentration to destroy part of the anchorage body and reduce the anchorage effect
