Main bridge continuous beam dismantling construction method
The invention relates to the technical field of bridge construction, and provides a main bridge continuous beam dismantling construction method which comprises the following operation steps: S1, building an underwater support system: building a foundation of the underwater support system by adopting a steel pipe pile, installing the steel pipe pile by adopting a percussion drill to lead a hole, and filling underwater concrete into a gap between the steel pipe pile and the hole, the tops of the steel pipe piles are spliced to form a crown block walking track supporting system, and a crown block is installed on the top of the crown block walking track supporting system. According to the method, the underwater support is erected to serve as a supporting system to be matched with a crown block walking track supporting system and a crown block, continuous operation of continuous beam dismantling can be achieved, efficiency is high, the construction period can be guaranteed, hoisting transportation of the dismantled part can be achieved without using large pontoons and floating cranes, and the method is mature in scheme, safe, reliable, low in construction risk and suitable for large-scale popularization and application. And vehicles, mechanical equipment and disassembled components can enter and exit from the yard conveniently and safely.
本发明涉桥梁施工技术领域，提出一种主桥连续梁拆除施工方法，包括以下操作步骤：S1、搭建水中支架体系：水中支架体系的基础采用钢管桩搭设，钢管桩安装先采用冲击钻引孔，并在钢管桩与孔间间隙灌注水下砼进行填充，钢管桩顶部通过拼装形成天车行走轨道支撑体系，其天车行走轨道支撑体系的顶部安装有天车。本发明通过搭设水中支架作为支撑体系配合天车行走轨道支撑体系及天车可实现连续梁拆除的连续作业、效率高，工期可保证，无需使用大型浮船、浮吊即可实现对拆除部分的吊装运输，该方法方案成熟、安全可靠，施工风险低，车辆、机械设备及拆除后的构件进出场方便、安全。
