Cable beam construction method of ground anchor type space cable suspension bridge
The invention discloses a cable beam construction method of a ground anchor type space cable suspension bridge, and relates to the technical field of suspension bridge construction, and the cable beam construction method comprises the following steps: S1, constructing an anchorage, a bridge tower and a foundation; s2, catwalk erection, main cable erection, catwalk hanging and cable clamp installation are completed in sequence, and then the top end of a sling is fixed to a cable clamp; s3, two sets of single-cable cable loading cranes are installed, the single-cable cable loading cranes can rotate relative to the main cable in the no-load state or walk in the length direction of the main cable, and the single-cable cable loading cranes can rotate relative to the main cable in the load state but do not slide; s4, the two groups of single-cable loading cranes synchronously and symmetrically lift the two main beam sections; s5, hoisting work of all the main beam sections is completed; and S6, applying a second-phase dead load, and designing the line shapes of the two main cables into a bridge line shape. According to the cable beam construction method, the construction mode of first cable and second beam is adopted, temporary transverse supports between the main cables do not need to be arranged, and the main cables are automatically designed into a bridge line shape along with gradual hoisting of the main beam sections.
本申请公开了一种地锚式空间缆悬索桥的缆梁施工方法，涉及悬索桥施工技术领域，包括以下步骤：S1:施工锚碇、桥塔及基础；S2:依次完成猫道架设、主缆架设、猫道改挂、索夹安装，然后将吊索的顶端固定于索夹；S3:安装两组单缆缆载吊机，单缆缆载吊机在空载状态能相对主缆转动或沿其长度方向行走，且单缆缆载吊机在载重状态能相对主缆转动但不滑动；S4:两组单缆缆载吊机同步对称提升两个主梁节段；S5:完成所有主梁节段吊装工作；S6:施加二期恒载，两根主缆的线形达成设计成桥线形。本申请的缆梁施工方法，采用先缆后梁的施工方式，无需设置主缆缆间临时横向支撑，且主缆随主梁节段逐步吊装自动达成设计成桥线形。
