Construction method of large-span three-continuous arch bridge
The invention discloses a construction method of a large-span three-continuous arch bridge, and belongs to the technical field of bridge engineering. The construction method of the large-span three-connection arch bridge comprises the steps that supports are arranged, V-shaped arch feet are formed on all side piers and all middle piers through construction, and side span main beam sections are assembled through the supports; buckling towers are arranged on the middle piers, one end of the first side span section is hinged to the V-shaped arch feet of the side piers, and one end of the second side span section is hinged to the V-shaped arch feet of the middle piers; arch ribs are correspondingly hoisted section by section on the V-shaped arch feet on the middle pier, and meanwhile, the first side span section and the second side span section are made to rotate by tensioning the buckling cables on the buckling towers, so that balance is achieved; the arch ribs are sequentially hoisted through buckling towers until a mid-span is formed, and the main beam sections are laid at the two ends of the two side-span main beam sections until a mid-span main beam section is formed through folding; and all the supports and all the buckling towers are dismantled. According to the construction method for the large-span three-continuous arch bridge, the number of the supports and the number of the buckling towers can be effectively reduced, and navigation conditions are met.
本发明公开了一种大跨度三连拱桥施工方法，属于桥梁工程技术领域。所述大跨度三连拱桥施工方法包括：设置支架，在各边墩上和各中墩上施工形成V形拱脚，且通过支架组装边跨主梁段；在各中墩上设置扣塔，将第一边跨段的一端铰接在边墩的V形拱脚上，第二边跨段的一端铰接在中墩的V形拱脚上；在中墩上的V形拱脚上对应逐节吊装拱肋，并同时通过张拉扣塔上的扣索使得第一边跨段和第二边跨段转动，实现平衡；通过扣塔依次吊装拱肋，直至形成中跨，在两个边跨主梁段两端铺设主梁节段，直至合拢形成中跨主梁段；拆除各支架和各扣塔。本发明实施例提供的一种大跨度三连拱桥施工方法，可以有效降低了支架和扣塔的数量，且满足通航的条件。
