Installation method of four-main-cable suspension bridge stiffening girder
The invention relates to a mounting method for a four-main-cable suspension bridge stiffening beam, and belongs to the technical field of bridge superstructure construction. The method comprises the following steps: erecting a cable-crossing crane for hoisting the stiffening beam on an inner main cable, hoisting the stiffening beam by the cable-crossing crane, and suspending the stiffening beam on the inner main cable through a first sling after the stiffening beam is hoisted to a set position; an opposite-pulling adjusting mechanism is installed between an outer main cable and the stiffening beam, the opposite-pulling adjusting mechanism is used for driving the stiffening beam and the outer main cable to move in the opposite direction, and the vertical distance between the stiffening beam and the outer main cable is gradually reduced; and when the length of the second sling on the outer main cable is larger than the vertical distance between the lower-layer bridge floor of the stiffening beam and the outer main cable, the stiffening beam is suspended on the outer main cable through the second sling.
本申请涉及一种四主缆悬索桥加劲梁的安装方法，属于桥梁上部结构施工技术领域。该方法包括在内主缆上架设吊运加劲梁的跨缆吊机，所述跨缆吊机起吊所述加劲梁，并将其吊运至设定位置后，将所述加劲梁通过第一吊索悬吊在所述内主缆上；在外主缆与所述加劲梁之间安装对拉调节机构，利用所述对拉调节机构驱动所述加劲梁和所述外主缆进行相向运动，使所述加劲梁和所述外主缆之间的竖直间距逐渐缩小；当所述外主缆上的第二吊索的长度大于所述加劲梁下层桥面与所述外主缆之间的竖向间距时，将所述加劲梁通过所述第二吊索悬吊在所述外主缆上。
