Multistage fortified array type hollow combined section anti-collision device
The invention relates to a multistage fortified array type hollow combined section anti-collision device which is composed of anti-collision sections connected with one another. The anti-collision section comprises a device main body which comprises an inner steel sleeve, an outer steel sleeve sleeved outside the inner steel sleeve, a rubber ring arranged between the inner steel sleeve and the outer steel sleeve, and a light filler filled in a gap between the inner steel sleeve and the outer steel sleeve; a prestressed steel bundle which is reserved between the inner steel sleeve and the outersteel sleeve and penetrates through the rubber ring, and a plurality of transverse partition plates are further arranged between the inner steel sleeve and the outer steel sleeve at intervals; and arolling module or the sliding module which is fixed on the device main body and is in contact with a to-be-protected base structure. Compared with the prior art, on the premise that it is guaranteed that no damage or little damage is caused to the surface layer making contact with the bridge structure in the normal use state, multi-stage protection of the bridge structure under the ship impact load is achieved.
本发明涉及一种多级设防的阵列式中空组合断面防撞装置，由相互连接的防撞节段组成，所述防撞节段包括：装置主体：其包括内钢套筒、套在内钢套筒外的外钢套筒、置于内钢套筒与外钢套筒之间的橡胶圈、填充在内钢套筒与外钢套筒之间间隙的轻质填料，以及留置于所述内钢套筒与外钢套筒之间并穿过所述橡胶圈的预应力钢束，在内钢套筒与外钢套筒之间还间距设置有若干横隔板；固定在装置主体上并与待保护的基础结构接触的滚动模块或滑动模块。与现有技术相比，本发明在保证正常使用状态下对与桥梁结构接触表层无损伤或损伤很小的前提下，实现船舶撞击荷载下对桥梁结构的多级保护。
