[0024] Example

[0025] A resistance device used to prevent rockfall, the main structure is like figure 1 , 2 , 3 and 4. The device includes a flexible steel wire mesh cover 1, a steel ring fastener 2, an umbrella rope 3, a drag umbrella sleeve 4, a steel strand 5, a steel wire 6, a drag umbrella 7 and an expansion bolt 8.

[0026] figure 1 In the middle, the right side of the stable rock mass, in which the flexible steel wire mesh cover is covered at the bottom of the dangerous rock mass (not shown in the figure). The upper part of the mesh cover is the dangerous rock mass, and sealant is used to fix it to the dangerous rock mass around the mesh cover.

[0027] When the device is implemented, the flexible steel wire mesh cover is covered on the bottom side surface of the dangerous rock mass, and the mesh cover is connected or bonded with the dangerous rock mass through the steel wire or the surrounding glue liquid, so that it will not fall or expand. The bolts 8 are fixed on both ...

Abstract

The invention relates to a resistance buffer device for rockfall prevention, which is characterized by comprising a flexible steel wire mesh enclosure, multiple steel ring fasteners, parachute cords, a drag parachute sleeve, steel stranded wires, steel wires, a drag parachute and expansion bolts, wherein two ends of the flexible steel wire mesh enclosure are connected with one ends of the steel stranded wires respectively; the multiple steel ring fasteners are arranged on the edge of the drag parachute and are connected with one ends of the parachute cords respectively; the other ends of the parachute cords are connected with the other ends of the corresponding steel stranded wires through the steel ring fasteners; the drag parachute is accommodated in the drag parachute sleeve; the top end of the drag parachute sleeve is connected with a steel wire rope with one fixed end; the flexible steel wire mesh enclosure is fixed at two ends of a dangerous rock through the expansion bolts. The resistance buffer device is reliably, conveniently and rapidly used for preventing rockfall from falling or rolling at a high speed and more powerfully provides safeguard for life and property security of people.

Description

technical field [0001] The invention belongs to the technical field of tunnel and slope engineering, and in particular relates to a resistance buffer device for preventing and controlling rockfall. Background technique [0002] In slope engineering or in areas where dangerous rocks are distributed, frequent accidents of falling rocks that hurt people or affect the progress of the project have brought great safety hazards to the safety of the project. Therefore, it is necessary to set up protective measures in the dangerous rock area to prevent All kinds of engineering accidents caused by falling rocks occurred. The existing rockfall prevention and control measures are mainly gabion nets, rockfall protection nets, rockfall prevention sheds, retaining walls plus stone fences, capsule fences, barbed wire and metal mesh coverings set up by trees, etc., but for small areas or this For the collapse prevention and control of very few dangerous rock masses, the above measures not o...
