Detachable self-floating cross-sea bridge steel pipe pile anti-collision device
The invention discloses a detachable self-floating cross-sea bridge steel pipe pile anti-collision device which comprises a detachable buffer floating base, a detachable anti-collision ring and a hydraulic roller assembly. The detachable buffer floating base is arranged on the outer wall of the bridge pier in a sleeving manner; the detachable anti-collision ring is installed on the top of the detachable buffering floating base and arranged outside the pier in a sleeving mode. A cavity is formed in the detachable anti-collision ring; the multiple hydraulic roller assemblies are installed on the inner wall of the detachable anti-collision ring and the inner wall of the detachable buffering floating base correspondingly, and the hydraulic roller assemblies are in rolling connection with the outer wall of the pier. And a non-uniform thickness multistable structure is mounted in the cavity. The anti-collision device can be repeatedly used, is suitable for different tide levels and water depths, can adapt to the change of the cross sectional area of the pier, reduces the abrasion between the anti-collision device and the pier, better buffers the impulsive force of a ship, effectively protects the pier from being damaged by collision of a workboat during construction, improves the safety of the bridge, and prolongs the service life of the bridge.
本发明公开一种可拆卸的自浮式跨海大桥钢管桩防撞装置，包括拆卸式缓冲飘浮底座、拆卸式防撞环和液压滚轮组件；拆卸式缓冲飘浮底座套设在桥墩外壁上；拆卸式防撞环安装在拆卸式缓冲飘浮底座的顶部，拆卸式防撞环套设在桥墩外；拆卸式防撞环内设有空腔；液压滚轮组件设有若干，若干液压滚轮组件分别安装在拆卸式防撞环的内壁上和拆卸式缓冲飘浮底座的内壁上，液压滚轮组件与桥墩的外壁滚动连接；其中，空腔内安装有非均匀厚度多稳态结构。本发明的防撞装置可重复利用且适用于不同潮位水深，可以适应桥墩横截面积地变化、减轻与桥墩间的磨损，更好地缓冲船舶的冲力，有效保护桥墩在施工时免受施工船撞击的损害，提高桥梁的安全性和使用寿命。
