Collapse rockfall protection net structure with tough energy dissipation function and installation method

Abstract

The invention discloses a collapse rockfall protection net structure with a tough energy dissipation function, and relates to the technical field of tough energy dissipation protection net structures. The structure comprises: a plurality of supporting columns, wherein the plurality of supporting columns are arranged at intervals along a slope supporting track; a plurality of fences which are arranged in the length direction of the supporting columns at intervals, wherein all the fences extend in the interval arrangement direction of the supporting columns; buffering devices which are used for connecting the fences to the supporting columns; and a steel wire mesh which is fixedly arranged on the fences. The buffering devices can conduct telescopic buffering, and the telescopic buffering strength of the multiple buffering devices is configured to be capable of driving the steel wire mesh to approach to be kept in the vertical state after falling rocks are prevented.

Description

technical field [0001] The invention relates to the technical field of ductile energy dissipation protection net structure, in particular to a structure and installation method of a collapse and rockfall protection net with ductile energy dissipation function. Background technique [0002] Existing protective nets are often directly fixed on the pillars. When the pillars are vertically fixed on the fixed foundation, they do not have the function of toughness and energy dissipation, and cannot face the impact of landslides in a flexible manner; and when the pillars are hinged on the fixed When the foundation is in the ground, it needs to use the anchor rope for further support, and a buffer device is arranged on the anchor rope. Although it can dissipate the energy of the collapsed rocks to a certain extent, it only relies on the buffer device on the anchor rope for energy dissipation. , the effect is mediocre, and after the impact of the falling rocks, the weight of the fall...

Problems solved by technology

[0002]Existing protective nets are often directly fixed on the pillars. When the pillars are vertically fixed on the fixed foundation, they do not have the function of toughness and energy dissipation, and cannot be used The flexible method faces the impact of landslides; when the pillar is hinged in the fixed foundation, it needs to use anchor ropes for further support, and buffer devices are arranged on the anchor ropes. However, it only relies on the buffer device on the anchor rope to dissipate energy, and the effect is average. After the impact of the rockfall, the weight of the falling rock still partially acts on the protective net, which is likely to cause it to continue to deform.
