Description
Technical field
The present invention relates to bridge pier protection guard, the protection dress of especially a kind of mountain area bridge pier anti-Rolling Stone and mud-rock-flow-impact
It sets.
Background technique
Bridge pier is keypoint part and weak link in science of bridge building, needs to lay special stress on protecting during traffic engineering operation,
Threat of various geological disasters, including avalanche Rolling Stone, mud-rock flow etc. are often subject to positioned at the bridge of high-mountain gorge areas, these ground
Matter disaster may cause bridge pier and generate damage and destroy, and Rolling Stone refers to individual block stones because certain reason is lost from side slope and cliff surface
After steady, the process of stationary state is eventually arrived at through motion modes such as whereabouts, rebound, jump, rolling or slidings, when Rolling Stone moves model
When there are job facilities in enclosing and cause certain loss, rockfall hazards are just constituted, mud-rock flow refers in mountain area or other ditches
Paddy deep gully, the dangerously steep area of landform, because landslide that heavy rain, severe snow or other natural calamities cause and carrying a large amount of mud
Husky and stone special mighty torrent, for there is the Rolling Stone threatened to bridge pier, thus it is possible to vary its motion profile and separate bridge pier, from
And achieve the effect that protect bridge pier, force Rolling Stone to change motion profile far from bridge pier, and need not be so that it becomes stationary state, this
Sample protective device neither will receive too big energy impact, and effective protection bridge pier, so that reaching reduces project amount, reduces and make
The purpose of valence, and in the process, if need Rolling Stone strength too big, protective device can be caused to impact, cause to protect
Device damage, in addition, the science of bridge building bridge pier in mountain area also needs to consider the threat of mud-rock flow, in certain Special zones, if bridge pier is same
When by the Rolling Stone of different directions and when mud-rock flow potential threat, protective device need to be provided simultaneously with the resistance of both geological disasters
Function, therefore propose the protective device of a kind of mountain area bridge pier anti-Rolling Stone and mud-rock-flow-impact.
Summary of the invention
The purpose of the present invention is to overcome the shortcomings of the existing technology, provides a kind of anti-Rolling Stone of mountain area bridge pier and mud-rock-flow-impact
