Arch bridge dismantling method
The invention relates to the technical field of bridges, and provides an arch bridge dismantling method which comprises the steps that 1, a bridge deck accessory structure and a bridge deck system are dismantled; 2, construction of a gantry crane and a bridge dismantling steel pipe support is conducted, the gantry crane stretches across the width direction of the bridge deck, and the bridge dismantling steel pipe support is used for dismantling arch ribs and beam bodies; (3) arch ribs and beam bodies are dismantled; 4, a steel sheet pile cofferdam is constructed, and an underwater bearing platform is dismantled; wherein before the arch bridge is dismantled, the gap between the support and the pier cap is temporarily solidified through cement paste pouring. Therefore, when the beam body on the pier cap is dismounted, the deviation of the beam body can be reduced, and the stability of the beam body during dismounting can be ensured.
本申请涉及桥梁技术领域，提供了一种拱桥拆除方法，其包括，步骤1：桥面附属结构的拆除以及桥面系的拆除；步骤2：龙门吊、拆桥钢管支架施工，龙门吊横跨桥面宽度方向，拆桥钢管支架用于拆除拱肋、梁体时使用；步骤3：拱肋拆除，梁体拆除；步骤4：钢板桩围堰施工，水中承台拆除；其中，在拱桥拆除前，对支座与墩帽间隙采取水泥浆灌注进行临时固结。基于此，可实现因此在拆除墩帽上的梁体时可以减小梁体发生偏移，保证梁体拆除时稳定性的效果。
