Single-tower cable-stayed bridge integral steel anchor beam on-tower scattered splicing construction method
The invention discloses a single-tower cable-stayed bridge integral steel anchor beam on-tower scattered splicing construction method. The method comprises the following steps that a left side module and a right side module of a steel anchor beam are prefabricated, and a steel corbel for supporting the steel anchor beam is prefabricated; mounting the steel corbel at the current mounting position of the tower column; hoisting the left side module and the right side module at the current mounting position; the left side module and the right side module are connected to form the steel anchor beam; and falling the steel anchor beam onto the steel corbel and connecting the steel anchor beam with the steel corbel. The integral steel anchor beam is split into four parts to be prefabricated and assembled after being hoisted to the installation position, the load of hoisting each time is reduced, the construction requirements of small transportation and use of small hoisting equipment are met, and the integral steel anchor beam is suitable for construction areas with poor transportation and hoisting conditions.
本申请公开一种独塔斜拉桥整体式钢锚梁塔上散拼施工方法，包括如下步骤：预制钢锚梁的左侧模块和右侧模块，预制支撑所述钢锚梁的钢牛腿；在塔柱的当前安装位置的安装所述钢牛腿；在所述当前安装位置上吊装所述左侧模块和右侧模块；连接所述左侧模块和右侧模块形成所述钢锚梁；使所述钢锚梁落架到所述钢牛腿上并进行连接。本申请将整体式钢锚梁分拆为四个部分进行预制，吊装到安装位置之后进行拼装，降低了每次吊装的载荷，实现了小型运输、使用小型吊装设备的施工要求，适用于运输和吊装条件不佳的施工区域。
