Description
Technical field
The present invention relates to a kind of prepressing type composite buffering energy dissipating cylinder, it is adaptable to security protection of the bridge pier under ship collision.
Background technology
While shipping traffic is fast-developing, waterway bridge is subjected to the risk of ship collision and is also increasing, conventional bridge
Collision accident often results in huge Socie-economic loss and casualties, and therefore the anti-ship problem of hitting of bridge has become as one
Important subject.
For reducing the loss that ship from colliding bridge accident is caused, Chinese scholars and project planner are opened to anticollision device, collision-prevention device
Substantial amounts of research is opened up.Because relatively small to effects of river course, construction costs is relatively low for Direct-type anticollision device, collision-prevention device, has obtained at present extensively
