Integral dismantling method for high-altitude large-span upper cross beam support of bridge tower
The invention relates to an integral dismantling method for a high-altitude large-span upper cross beam support of a bridge tower, and relates to the technical field of bridge construction. The integral dismantling method comprises the following steps that a plurality of steel strands with the same length are cut, and the four steel strands are arranged on four oil cylinders in a one-to-one penetrating mode; the four oil cylinders penetrating through the steel strands are hoisted and installed at the four corners of the top face of the upper cross beam correspondingly; the bottom end of the steel strand penetrates through the upper cross beam to be fixedly connected to the upper cross beam support; a control center and a hydraulic pump station are installed, and the hydraulic pump station is connected with all the oil cylinders through hydraulic oil pipes; the control center is connected with the hydraulic pump station and the oil cylinder through signal lines. The control center controls the steel strands of the four oil cylinders to be tightened synchronously through the hydraulic pump station, and the stress of the upper cross beam is converted from the brackets to the steel strands; the bracket is dismantled; and the control center controls the steel strands of the four oil cylinders to synchronously lower down the whole upper cross beam bracket through the hydraulic pump station. According to the overall dismantling method, the upper cross beam support overall dismantling method is adopted, safety and reliability are achieved, and the construction risk is greatly reduced.
本申请涉及一种桥塔高空大跨度上横梁支架的整体拆除方法，涉及桥梁施工技术领域，包含以下步骤：切割若干根等长的钢绞线，将四股钢绞线分别一一穿设于四个油缸；将穿好钢绞线的四个油缸分别吊运安装至上横梁顶面四角；将钢绞线的底端穿过上横梁固定连接于上横梁支架；安装控制中心和液压泵站，液压泵站通过液压油管连接所有油缸；所述控制中心通过信号线连接液压泵站和油缸；控制中心通过液压泵站控制四个油缸的钢绞线同步绷紧，将上横梁受力从牛腿转换至钢绞线；拆除牛腿；控制中心通过液压泵站控制四个油缸的钢绞线同步下放整个上横梁支架。本申请的整体拆除方法，采用上横梁支架整体拆除方法，安全可靠，大大降低了施工风险。
