The invention discloses a fabricated bridge pier protection device. The fabricated bridge pier protection device comprises an arc-shaped mounting plate and an arc-shaped hollow cover, wherein an arc-shaped bearing plate is arranged in the center of the side face of the arc-shaped hollow cover, the arc-shaped bearing plate is slidably connected with the arc-shaped hollow cover, a buffer mechanism is arranged in the arc-shaped hollow cover, the buffer mechanism comprises three lead screws, and the three lead screws are movably arranged in the center of an inner cavity of the arc-shaped hollow cover. According to the fabricated bridge pier protection device, the arc-shaped bearing plate is buffered for the first time through two buffering air bags, and the lead screws rotate to drive a cross propeller frame at the bottom end to rotate, so that the arc-shaped bearing plate is buffered for the second time; an inner threaded sleeve drives a floating plate to move downwards, and the floating plate is subjected to buoyancy of water when moving downwards, so that the arc-shaped bearing plate is buffered for the third time; and the protection device conducts multi-directional anti-collision treatment on a bridge pier at the same time, the resistance and buoyancy of water are effectively utilized to conduct buffering treatment on collision for multiple times, the buffering effect is good, and the service life is long.
本发明公开了一种装配式桥梁桥墩防护装置，包括弧形安装板以及弧形中空罩，所述弧形中空罩的侧面中心处设有弧形承压板，且所述弧形承压板与弧形中空罩滑动连接，所述弧形中空罩的内部设有缓冲机构，所述缓冲机构包括三个丝杆，且三个所述丝杆均活动设置于弧形中空罩的内腔中心处。本发明通过两个缓冲气囊对弧形承压板做第一次缓冲处理，丝杆转动带动底端的十字螺旋桨架转动，从而对弧形承压板做第二次缓冲处理，内螺纹套管带动浮板下移，浮板下移时受到水的浮力，从而对弧形承压板做第三次缓冲处理，该防护装置同时为桥墩做多方位的防撞处理，且有效利用水的阻力以及浮力对碰撞做多次缓冲处理，缓冲效果好，使用寿命长。
