A kind of tough composite buffer for slope flexible protection system and its design method

Abstract

The invention discloses a toughness composite buffer for a slope flexible protection system, comprising: a supporting steel pipe, two ends of which are respectively fixed on a spring base plate and a tension anchor plate; A plate hole, the supporting steel pipe passes through the sliding plate hole, so that the sliding plate is slidably sleeved on the supporting steel pipe; a buffer spring, the buffer spring is sleeved on the supporting steel pipe, both ends are respectively connected with the spring base plate and the sliding plate; the first steel cable, one end of the first steel cable passes through the sliding plate and is anchored on the sliding plate with a metal rope anchor, the first steel cable The other end is connected to the first support rope; when the impact energy of the system is within the normal working energy level, the buffer spring works independently, produces elastic deformation and recovers with the cleaning of the falling rock; when the impact energy exceeds the normal working energy level, the support is started The buckling of the steel column realizes the composite energy dissipation.

Description

technical field [0001] The invention relates to a buffer for a slope flexible protection system, in particular to a tough composite buffer used for a slope flexible protection system and a design method thereof, belonging to the field of slope geological disaster protection. Background technique [0002] The passive flexible protection system is a protective structure widely used in the prevention and control of slope geological disasters, and generally consists of supporting steel columns, metal intercepting nets, energy consumers and anchoring systems. [0003] The protection energy level is a key indicator for evaluating its protection performance. The more energy dissipated when subjected to impact, the stronger its protection ability and the higher the protection energy level. The energy dissipated by the energy dissipator in the system accounts for the largest proportion, so the research on the energy dissipator is very important to the passive flexible protection syst...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a flexible composite buffer used in the slope flexible protection system and its design method, which mainly solves the troublesome and insufficient maintenance of energy consumers in the existing flexible protection system under the impact of multiple accumulated small energy levels economically sound question

And the buffer mechanism of the existing slope flexible protection system is unreasonably set, and the toughness is insufficient, which easily leads to the problem of "braking effect"
