Whole-section symmetrical double-cantilever erection method for steel truss girder of beach large-span cable-stayed bridge
The invention relates to the technical field of bridge construction, and is mainly suitable for erecting a large-span cable-stayed bridge in a beach area. The whole-section symmetrical double-cantilever erecting method for the steel truss girder of the beach large-span cable-stayed bridge comprises the steps that a main tower foundation is constructed; two columns of buttresses are arranged on the mudflat in the direction of transporting the whole section of steel truss girder, and slideway girders are arranged on the tops of the buttresses; constructing a main tower column; the whole section of steel truss girder is moved to the to-be-hoisted positions on the two sides of the main tower section by section along the slide way girder and stored on the slide way girder in advance; the whole section of steel truss girder is lifted section by section from the main tower to the two sides and symmetrically erected on the cantilever; a stay cable is hung and tensioned on the erected steel truss girder; and the steel truss girder is erected, stay cables are hung, tensioning is completed, and the slideway girder and the buttresses are disassembled. Compared with an existing erecting method, the bridge erecting construction cost can be reduced, the construction period is shortened, and the problem of idling is solved.
本发明涉及桥梁施工技术领域，主要适用于在滩地区域对大跨度斜拉桥进行架设。具体公开了一种滩地大跨度斜拉桥钢桁梁整节段对称双悬臂架设方法，包括主塔基础施工；在滩地沿运输整节段钢桁梁方向设置两列支墩，在支墩顶上设置滑道梁；主塔塔柱施工；将整节段钢桁梁逐段沿滑道梁移运至主塔两侧待起吊位置，并在滑道梁上提前存放；从主塔开始向两侧，从滑道梁上逐段提升并对称悬臂架设整节段钢桁梁；在架设好的钢桁梁上挂设、张拉斜拉索；钢桁梁架设完成，斜拉索挂设、张拉完成，拆除滑道梁及支墩。本发明相对于现有架设方法，能够降低桥梁架设施工成本，加快工期，解决了窝工问题。
