Anchoring device for preventing landslide geological disasters

Abstract

The anchoring device for preventing the landslide geological disasters comprises a first intercepting mechanism, a second intercepting mechanism and a third intercepting mechanism which are arranged at intervals, and each intercepting mechanism comprises a plurality of anchoring assemblies arranged at intervals and intercepting assemblies arranged between the adjacent anchoring assemblies; the anchoring assembly comprises an anchoring pipe, a plurality of anchoring parts and a pushing piece, the pipe wall of the anchoring pipe is provided with a plurality of guide hole units which are arranged at intervals in the axial direction, each guide hole unit comprises at least one guide hole, the anchoring parts are arc-shaped and are slidably inserted into the guide holes, and the pushing piece is slidably inserted into the anchoring pipe; the intercepting assemblies are connected to the two adjacent anchoring pipes and provided with a plurality of intercepting holes, and the sizes of the intercepting holes of the intercepting assemblies in the first intercepting mechanism, the second intercepting mechanism and the third intercepting mechanism are sequentially reduced. The device can intercept gliding stones and soil in batches.

Description

technical field [0001] The invention relates to the technical field of landslide geological anchoring, in particular to an anchoring device for preventing landslide geological disasters. Background technique [0002] During the construction of mining, highway construction, railway construction, foundation pit construction and other projects, some projects will form steep slopes with large slopes on the mountain. This kind of steep slope is formed by construction without any vegetation on it, so landslides are prone to occur Condition. [0003] Notification No. CN111456038B discloses a composite anchor rod suitable for loess slopes, including a main rod with a grouting hole in the middle. The hole spacing is gradually increased from the front end of the main rod to the rear end of the main rod, and the rear end of the main rod is connected with an anchoring pretightening force applying device. Through the grouting hole and the grouting hole of the main rod, cement slurry, c...

AI Technical Summary

Problems solved by technology

[0004] The structural strength of the soil is enhanced by anchoring the anchor rods in the slope, but when the stone above the slope slides down with the soil, as the sliding speed increases, it can drive the soil below to slide synchronously to form a soil landslide. The anchoring device can only reinforce the local soil. When the upper landslide is initially formed, the anchoring device lacks the ability to intercept the sliding soil and stones, and lacks the ability to further organize the soil landslide.
