Shrink sleeve damping device, rockfall vibration damping shed tunnel and design method thereof

Abstract

The invention discloses a shrink sleeve damping device aiming at solving the problems in the prior art that direction protection of the top of a rockfall protection shed tunnel is limited, or maintenance thereof is complex. The provided shrink sleeve damping device is characterized in that the shrink sleeve damping device comprises an upper bearing plate, a vibration damping sleeve and a lower bearing plate; the lower bottom surface of the upper bearing plate is in static connection with the top of the vibration damping sleeve; the bottom of the vibration damping sleeve is in static connectionwith the upper top face of the lower bearing plate; the vibration damping sleeve is composed of metal shrink tubes of multiple layers in inner and outer coaxial socket; the inner-layer metal shrink tubes are higher than the outer-layer metal shrink tubes; the metal shrink tubes at adjacent layers are closely connected. A rockfall vibration damping shed tunnel, and design methods of the shrink sleeve damping device and the rockfall vibration damping shed tunnel are also provided. The shrink sleeve damping device, rockfall vibration damping shed tunnel and design methods thereof have the advantages that the shrink damping device has an ingenious design, realizes classification of energy consumption and repeated multiple energy dissipation and vibration reduction functions and improves damping efficiency of the device; the rockfall vibration damping shed tunnel can solve the problem that traditional shed tunnel protection systems are not easy to repair and maintain; design methods are simple and practical.

Description

technical field [0001] The invention relates to a vibration damping device and a design method thereof, in particular to a telescopic sleeve vibration damping device and a design method thereof, and belongs to the fields of disaster prevention and control engineering in mountainous areas and road and bridge engineering. Background technique [0002] Building shed tunnels is a disaster prevention and control project built in the half-cut section of road traffic in mountainous areas to prevent landslides from destroying the road surface, prevent landslides and rockfalls, and minimize the hazards of landslides and rockfalls. The construction of traffic routes needs to go through mountainous areas. Road construction in these areas involves a lot of slope excavation and support problems, and the problems of dangerous rock collapse and falling rocks on the slope are prominent. Especially in accident-prone areas, a large number of falling rocks and falling rocks often damage the ro...

AI Technical Summary

Problems solved by technology

Falling rocks cannot stay on the top of this type of product, so in the design of the entire shed tunnel protection system, it is necessary to reserve a space for accumulation of falling rocks, and the falling rocks will continue to roll down with the arc surface of the vibration damping shed, which will not achieve the goal of avoiding rockfall hazards as much as possible

At the same time, after the arc-shaped shock-absorbing roof is damaged, the repair of some parts is relatively complicated
