Rockfall energy dissipation guide structure

Abstract

The rockfall energy dissipation guiding structure comprises an energy dissipation guiding main groove and a plurality of energy dissipation guiding branch grooves which are formed below a dangerous rock body along a slope, a rockfall opening is formed in the upper end of each energy dissipation guiding branch groove, and the lower end of each energy dissipation guiding branch groove is communicated with the energy dissipation guiding main groove in a converging mode; the energy dissipation guide main grooves and the energy dissipation guide branch grooves are each of a bent structure providedwith a plurality of buffer energy dissipation bends, falling rocks roll along the designed movement rail of the grooves, the bent energy dissipation grooves are adopted to change the speed direction of the falling rocks to reduce energy, and the situation that existing falling rocks are large in energy level and cannot be effectively prevented and treated is solved. The device is simple in structure and low in cost, is made of original rock and soil materials and waste rubber, uses local materials, is low in treatment and maintenance cost, and is convenient to popularize and apply.

Description

technical field [0001] The invention relates to a rockfall energy dissipation guiding structure, which belongs to the technical field of slope protection. Background technique [0002] Rockfall is some rock blocks with high falling frequency that exist on steep rock slopes. It has the characteristics of strong concealment, random distribution, uncertainty, suddenness, and strong disaster-causing and destructive properties, which makes the technology of rockfall prevention and control difficult. Large, large economic cost of prevention and treatment. If all-round protection measures cannot be taken well, falling rocks will often destroy many important protection objects such as roads and houses, and there will be great safety hazards. [0003] Falling rocks rolling down from a high place have the impact kinetic energy of high-speed movement. Common rockfall prevention measures include rockfall retaining walls, passive protective nets, etc., but the energy level of limited ro...

If all-round protection measures cannot be taken well, falling rocks will often destroy many important protection objects such as roads and houses, and there will be great safety hazards

[0003] Falling rocks rolling down from a high place have the impact kinetic energy of high-speed movement. Common rockfall prevention measures include rockfall retaining walls, passive protective nets, etc., but the energy level of limited rockfall prevention and control is small, and the energy level of rockfall is still large. The situation destroyed by falling rocks
