旧桥拆除施工通航保证及安全措施研究

Study on Navigation Guarantee and Safety Measures for Demolition of Old Bridges

龙桥东江大桥位于惠州市博罗县龙溪镇境内,是龙溪镇进入桥头镇的一座桥梁,横跨东江航道,航道运输较为复杂,施工期间浮吊、平驳船和桥墩与桩基础切割作业平台和围堰等附属施工设施,都将压缩航道,使得通行船舶与这些设施碰撞的概率增加,对施工安全有较大威胁。分析了在拆除桥梁的过程中如何保证通航,以及其相应的安全方案。

Longqiao Dongjiang Bridge is located in Longxi Town, Boluo County, Huizhou City. It is a bridge connecting Longxi Town into Qiaotou Town. It spans the Dongjiang Waterway. The navigation of the channel is complicated. During the construction period,floating cranes, barges and piers are used. The pile foundation cutting operation platform and auxiliary construction facilities such as cofferdams will compress the navigation channel, which increases the probability of collision between the passing ship and these facilities, which poses a greater threat to construction safety. It analyzes how to ensure navigation during the process of dismantling the bridge and its corresponding safety plan.
