Multistage energy-absorbing anti-collision device for bridge pier and construction method of multistage energy-absorbing anti-collision device
The invention belongs to the field of constructional engineering, and particularly relates to a bridge pier multistage energy absorption anti-collision device and a construction method thereof. The device comprises an energy dissipation space arranged around the bridge pier by a circle, the energy dissipation space is defined by an inner-layer steel plate, an outer-layer steel plate and a cover plate, the inner-layer steel plate is attached to the outer surface of the bridge pier, and the outer-layer steel plate is parallel to the inner-layer steel plate; springs or springs and corrugated steel plates are further arranged in the energy dissipation space, the springs are connected with the inner-layer steel plates and the outer-layer steel plates in the radial direction of the pier, the middle faces of the corrugated steel plates are parallel to the inner-layer steel plates to form a middle layer of the energy dissipation space, and through holes allowing the springs to stretch out and draw back are formed in the corrugated steel plates. According to the anti-collision device, through multi-layer energy absorption of the springs, the corrugated steel plates and the rubber, collision kinetic energy acting on the pier is effectively reduced, and therefore effective protection on the pier is achieved.
本发明属于建筑工程领域，具体涉及一种桥墩多级吸能防撞装置及其施工方法。该装置包括一个绕桥墩周向一周设置的消能空间，消能空间由内层钢板、外层钢板和盖板围合构成，内层钢板贴合桥墩外表面设置，外层钢板平行于内层钢板；在消能空间内部，还设置有弹簧或弹簧和波纹钢板，弹簧沿桥墩径向方向连接内层钢板和外层钢板，波纹钢板的中面平行于内层钢板形成消能空间的中间层，波纹钢板上开设有供弹簧伸缩通过的通孔。防撞装置通过弹簧、波纹钢板和橡胶三种材料的多层次吸能，有效减少作用于桥墩的碰撞动能，从而实现对桥墩的有效防护。
