Problems solved by technology

In fact, the anchor rods in this type of protective net structure cannot provide sufficient normal anchoring force in the direction vertical to the slope surface, and cannot actively reinforce the overall stability of the slope. Once the overall instability of the slope occurs , short anchor rods and protective nets cannot play a role in supporting and reinforcing unstable slopes, and are not active protection in the strict sense.

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] refer to figure 1 , figure 2 and image 3 , the broken rock slope anchor pier type active protective net structure of the present invention comprises: longitudinal support ropes 11 and transverse support ropes 12 arranged on the slope surface in a grid pattern; anchor piers 31 and anchor members are arranged on the net At the grid node, the anchor pier 31 forms a fixed connection with the longitudinal support rope 11 and the transverse support rope 12 at the grid node. The two ends of the anchor member are respectively anchored and connected with the anchor pier 31 and the stable rock formation; It is laid on the side slope slope, connected with the vertical support rope 11 and the horizontal support rope 12 around the grid through the suture rope 13, and separated into a grid shape. The anchoring member is anchored on the slope surface throu...

Abstract

Provided is a crush rock slope anchorage pier type active protective net structure. The overall stability of a slope is effectively improved, and crush block bodies can be effectively protected. The crush rock slope anchorage pier type active protective net structure comprises longitudinal supporting ropes, horizontal supporting ropes, an anchorage pier, an anchoring component and a high-strength steel rope net. The longitudinal supporting ropes and the horizontal supporting ropes are arranged on the face of the slope in a mesh shape. The anchorage pier and the anchoring component are arranged at mesh nodes. The anchorage pier is fixedly connected with the longitudinal supporting ropes and the horizontal supporting ropes at the mesh nodes. The two ends of the anchoring component are connected with the anchorage pier and a stable rock stratum in an anchoring mode. The high-strength steel rope net is arranged on the slope in a paving mode in a curve shape and is connected with the longitudinal supporting ropes and the horizontal supporting ropes on the peripheries of meshes through sewing lines, and the high-strength steel rope net is divided to be in a mesh shape.

Description

technical field [0001] The invention relates to slope protection engineering, in particular to an anchor pier type active protection net structure for broken rock slopes. Background technique [0002] For broken rock slopes, active protection nets are usually used for protection at present. The active protection net is fixed on the slope by a short anchor rod with a length of 3-4m, and the designed anchor rod tension is usually not more than 50kN. In fact, the anchor rods in this type of protective net structure cannot provide sufficient normal anchoring force in the direction vertical to the slope surface, and cannot actively reinforce the overall stability of the slope. Once the overall instability of the slope occurs , short anchor rods and protective nets cannot play a role in supporting and reinforcing unstable slopes, and are not active protection in the strict sense. Contents of the invention [0003] The technical problem to be solved by the present invention is ...
