Construction method for fast dismantling whole hole of hollow slab girder of approach bridge of inland waterway
The invention belongs to the field of old bridge dismantling, and particularly discloses a whole-hole quick dismantling construction method for an approach bridge hollow slab girder of an inland waterway, which specifically comprises the following steps of: hoisting and dismantling a bridge deck system guardrail of the approach bridge hollow slab girder; through holes are formed in side plate flange plates and a middle plate on the two sides of the approach bridge hollow plate beam respectively, and then a steel wire rope penetrates through the two adjacent through holes in the same side to carry the bottom of the approach bridge hollow plate beam, so that sliding or unhooking is prevented during follow-up hoisting; a floating crane is matched with a steel wire rope to hoist the whole hole of the approach bridge hollow slab girder to a storage yard for breaking, so that the whole hole of the inland waterway hollow slab girder is quickly removed. The through holes are formed in the side plate flange plate and the middle plate of the approach bridge hollow plate beam, and the steel wire ropes penetrate through the through holes for bottom carrying, so that the whole-hole stable and rapid hoisting of the hollow plate beam can be realized, the safety risk is greatly reduced, the overall dismantling time is shortened, the construction efficiency is effectively improved, and the construction cost is reduced. The method is suitable for the situation that the channel is not sealed for a long time.
本申请属于老桥拆除领域，具体公开了一种内河航道引桥空心板梁整孔快速拆除施工方法，该施工方法具体为：将引桥空心板梁的桥面系护栏进行吊装拆除；分别在引桥空心板梁两侧的边板翼缘板及中板开设通孔，然后利用钢丝绳穿过同侧相邻两个通孔以对引桥空心板梁进行兜底，从而防止后续吊装时出现滑动或脱钩；使用浮吊配合钢丝绳将引桥空心板梁整孔吊装至堆场进行破除，以实现内河航道空心板梁整孔快速拆除。本申请通过在引桥空心板梁的边板翼缘板和中板上开设通孔，并利用钢丝绳穿过通孔进行兜底，能够实现空心板梁整孔平稳快速吊装，不仅大大降低了安全风险，而且缩短了整体拆除时间，有效提升了施工效率，适用于航道不具备长时间封航的情况。
