Quick construction method for separated steel box girder of self-anchored suspension bridge
The invention relates to a quick construction method for a separated steel box girder of a self-anchored suspension bridge, and belongs to the technical field of bridge construction. Comprising the following steps: S1, setting each construction area; s2, a support is built; s3, a floating crane is used for hoisting one steel box girder to a hoisting support, and meanwhile, a guide beam and other steel box girders are hoisted to a pushing support; s4, simultaneous construction is conducted; s5, connecting the steel box girders; s6, after the cross beam in the hoisting area is fixed, carrying out cable-stayed cantilever splicing on the cable-stayed cantilever splicing bracket to splice a steel box beam; s7, closure of the pushing area; s8, after closure of the pushing area is completed, steel box girders on the left side and the right side of the bearing platform are hoisted in the hoisting area; s9, the cable-stayed suspended splicing beam in the cable-stayed suspended splicing area and the steel box beam on the hoisting area on the other side are closed; s10, the steel box girders on the left side and the right side of the bearing platform are closed to complete construction of the whole bridge section; according to the method, the problem that construction cannot be rapidly carried out when the steel box girder is erected under navigation limitation and shoal area influence is solved.
本发明涉及一种自锚式悬索桥分离式钢箱梁快速施工方法，属于桥梁施工技术领域。包括以下步骤：S1：设定各个施工区；S2：搭建支架；S3：利用浮吊将一幅幅钢箱梁吊装至吊装支架，同时将导梁和其他钢箱梁吊装至顶推支架上；S4：同时施工；S5：连接钢箱梁；S6：当吊装区内横梁固定完成后在斜拉悬拼支架上进行斜拉悬臂拼接钢箱梁；S7：顶推区合龙；S8：顶推区合龙完成后在吊装区内吊装承台左右两侧的钢箱梁；S9：将斜拉悬拼区中的斜拉悬拼梁与另一侧吊装区上的钢箱梁进行合龙；S10：将承台左右两侧的钢箱梁进行合龙完成整个桥梁梁段的施工；本发明解决了在受通航限制及浅滩区影响的钢箱梁架设时无法快速进行施工的问题。
