Problems solved by technology

Rock masses with joint surfaces are not currently in danger, but as time goes on, hazards such as slippage are likely to occur, so disaster prevention measures must be taken in advance

Abstract

The invention relates to the technical field of geological weak surface disaster prevention, and discloses a disaster prevention device for a geological weak surface. The disaster prevention device comprises a plurality of anti-sliding support arms arranged on the side walls of a main rock body and sliding rock masses, and containing anti-falling mechanisms arranged below the anti-sliding supportarms, wherein each anti-sliding support arm comprises a base arranged on the main rock body, a sleeve rod fixed on the base, a sliding arm slidably connected to the sleeve rod and a shock absorbing spring located between the bottom end of the sleeve rod and the sliding arm, and the sliding arms are fixed to the side walls of the sliding rock masses. According to the disaster prevention device, theanti-sliding support arms are arranged to effectively reinforce rock bodies with the weak surfaces of the joint surfaces, the sliding rock masses are effectively prevented from sliding, and the firstprotection barrier function is achieved for the disaster prevention; and the second protection barrier function is achieved for the disaster prevention through the arrangement of the containing anti-falling mechanisms, when the anti-falling support mechanisms cannot prevent the sliding rock masses from sliding, the containing anti-falling mechanisms are used for containing the falling large and small rock masses or blocking the rock masses, and the loss is reduced to the lowest.

Description

technical field [0001] The invention relates to the technical field of disaster prevention for geological weak surfaces, in particular to a disaster prevention device for geological weak surfaces. Background technique [0002] Geological weak surfaces are unstable slopes or rock masses that threaten counties, important market towns, and important public infrastructure. They are weak surfaces of rock masses or joint surfaces, which is what we call stress-weak surfaces. When prone to breakage, sliding surface. A joint is a type of fracture structure, which refers to a rock that is split and there is no obvious relative displacement on both sides of the crack (as opposed to a fault with obvious displacement). Joints are actually a very common structural geological phenomenon. In layman's terms, it is the cracks we see on rock outcrops. This is a crack that appears due to the force of the rock, but there is no obvious (visible to the eyes) displacement on both sides of the cr...
