Bridge pier safety protection device of urban road bridge
The invention discloses a bridge pier safety protection device of an urban road bridge, and relates to the field of bridge pier protection, the bridge pier safety protection device comprises a bridge pier and an expansion assembly, the expansion assembly is installed at the bottom of the outer side of the bridge pier, and the expansion assembly can move in the vertical direction of the bridge pier under the action of external force; the energy absorption assembly is installed on the outer side of the expansion assembly, the protection assembly is installed on the outer side of the energy absorption assembly, and the protection assembly, the energy absorption assembly and the expansion assembly can move in the vertical direction of the pier under the action of external force; according to the pier safety protection device for the urban road bridge, when the roller rotates to change the direction of collision force after collision occurs, direction guidance is provided after collision, so that the collision body is balanced again after collision occurs, and secondary damage is prevented; through step-by-step energy absorption protection of the protection assembly, the energy absorption assembly and the collision assembly, a collider and a bridge pier can be protected to the maximum extent, and when urban rainstorm road surface water accumulation is serious, the protection assembly, the energy absorption assembly and the collision assembly float upwards along the T-shaped keys under the buoyancy effect of water; under the condition that no water is accumulated on the road surface, the bottoms of the protection assembly, the energy absorption assembly and the collision assembly fall on the ground, the additional load of the weight of the protection device on the pier is reduced, and the service life of the pier is prolonged.
本发明公开了一种城市道路桥梁的桥墩安全防护装置，涉及桥墩防护领域，包括桥墩，膨胀组件，其安装于桥墩外侧底部，且膨胀组件能够在外力的作用下沿桥墩竖直方向移动；吸能组件，其安装于膨胀组件外侧，防护组件，其安装于吸能组件外侧，防护组件、吸能组件和膨胀组件能够在外力的作用下沿桥墩竖直方向移动；该城市道路桥梁的桥墩安全防护装置，通过在发生撞击后滚筒旋转改变碰撞力的方向时，并提供碰撞后的方向导向，使碰撞发生后碰撞体重新找回平衡，防止二次伤害，通过防护组件、吸能组件和碰撞组件的逐级吸能防护能够最大限度地保护碰撞者和桥墩，在城市暴雨路面积水严重时，防护组件、吸能组件和碰撞组件在水的浮力作用下沿T型键向上浮动，减少水流流过桥墩底部的阻力以减少桥墩的横向负载，在路面无积水的情况下，防护组件、吸能组件和碰撞组件底部落于地面，减少防护装置重量对桥墩的额外负载，提高桥墩的使用寿命。
