Concrete arch bridge cable-stayed buckling cantilever pouring construction method
The invention particularly relates to a concrete arch bridge cable-stayed buckling cantilever pouring construction method. The problems that a rear anchor system of a cable crane is high in construction cost, and a cable cannot cover the whole bridge are solved. The invention discloses a concrete arch bridge cable-stayed buckling cantilever pouring construction method. The method comprises the steps that S1, a cable crane system is constructed; s2, boundary pier and approach bridge structure construction; s3, buckling towers are installed on the upper sides of the boundary piers; s4, pouring construction of the arch rings is conducted in a segmented mode till the arch rings are closed; s5, dismantling the temporary buckle cable, the back cable and the buckle tower; s6, a bent frame is constructed on the arch ring; and S7, the arch bridge main beam body is constructed on the upper side of the bent frame. Full-bridge coverage of a hoisting system during concrete arch bridge cable-stayed buckling cantilever pouring is achieved, the gravity type anchors are adopted, the dead weights of permanent structures such as the guiding bridge beams and the guiding bridge piers are used for resisting back anchoring counter force, the construction cost is reduced, and the method can be suitable for V-shaped arch bridge construction scenes with the guiding bridges.
本发明具体是一种混凝土拱桥斜拉扣挂悬臂浇筑施工方法，解决了缆索吊的后锚系统施工成本高昂、缆索不能覆盖全桥的问题。一种混凝土拱桥斜拉扣挂悬臂浇筑施工方法，步骤S1：缆索吊系统的施工；步骤S2：分界墩、引桥结构的施工；步骤S3：在分界墩的上侧安装扣塔；步骤S4：分段进行拱圈的浇筑施工，直至拱圈合拢；步骤S5：拆除临时扣索、背索和扣塔；步骤S6：在拱圈上施工排架；步骤S7：在排架的上侧进行拱桥主梁体的施工。本发明实现了混凝土拱桥斜拉扣挂悬臂浇筑时吊装系统的全桥覆盖，采用重力式锚，利用引桥梁、引桥墩这些永久结构的自重抵抗后锚反力，降低了施工成本，可适用于V形、有引桥的拱桥施工场景。
