Cable-stayed bridge main tower dismantling method and multifunctional tower dismantling machine
The invention discloses a cable-stayed bridge main tower dismantling method and a multifunctional tower dismantling machine. The cable-stayed bridge main tower dismantling method comprises the steps that rails are erected on the two sides of a bridge tower, and a door-shaped support and an operation platform are installed; the door-shaped support is driven to climb to the tower top along the track, and two lifting devices are installed on the horizontal portion of the door-shaped support; after the hoisting holes are drilled, the top section of the bridge tower is cut in the horizontal direction, and then the top section of the bridge tower is cut into two bridge tower blocks in the vertical direction; using a lifting device to translate the bridge tower blocks on the same side outwards out of the range of the bridge tower and then lowering the bridge tower blocks to a bridge floor; and the door-shaped support is driven to move downwards, and the previous steps are cyclically repeated to dismantle the bridge tower from top to bottom in a segmented mode. According to the method, the bridge tower sections which are cut in a segmented mode are transferred to the bridge floor through the hoisting system, the hoisting system is directly arranged at the top end of the bearing support, large hoisting equipment and auxiliary supports do not need to be additionally arranged, the method can adapt to various different environment conditions and construction requirements, safe and rapid dismantling of the cable-stayed bridge tower is achieved, the construction cost is effectively reduced, and the construction efficiency is improved. And the construction efficiency and the construction quality are ensured.
本发明公开了斜拉桥主塔拆除方法及多功能拆塔机，包括：在桥塔两侧搭设轨道、安装门型支架和作业平台；驱动门型支架沿轨道爬升至塔顶，在门型支架的水平部上安装两个起重装置；钻设吊装孔后沿水平方向切割桥塔顶部节段，再沿竖直方向将其切分为两个桥塔分块；使用起重装置将同侧的桥塔分块向外平移出桥塔范围后下放至桥面；驱动门型支架下移，循环重复前序步骤将桥塔从上至下分段拆除。本发明将分段切割后的桥塔节段通过起重系统移运至桥面，起重系统直接设置在承重支架顶端，不需要额外配置大型起重设备及辅助支架，能够适应多种不同的环境条件和施工需求，实现斜拉桥桥塔的安全、快速拆除，有效降低了施工成本，并保证施工效率和施工质量。
