Construction method for installing self-anchored buckling tower on steel structure bridge
The invention relates to a construction method for installing a self-anchored buckling tower on a steel structure bridge. The device comprises a front inhaul cable, a buckling tower, a buckling tower anchor beam, a rear inhaul cable, a rear anchor point, a steel anchor box, a steel strand, a steel anchor beam, a P anchor and the like. The buckling tower is arranged on the bridge bearing platform and rigidly connected with the steel beam, the buckling tower anchor beam is arranged on the buckling tower and forms a whole with the buckling tower, and the front inhaul cable anchoring device and the rear inhaul cable anchoring device are arranged at the two ends of the buckling tower respectively and used for adjusting inhaul cable force and bridge linetype. The rear anchor point is arranged outside the steel beam end cross beam and used for anchoring the rear inhaul cable, and the steel anchor box is arranged inside the steel beam end cross beam and used for anchoring the steel strand. The P anchor is pre-buried on a bearing platform during construction of the pier bearing platform, the steel anchor beam is connected with the pre-buried P anchor, one end of the steel strand penetrates through a hole preset in a steel beam bottom plate to be anchored with the steel anchor box, the other end of the steel strand is anchored with the steel anchor beam, and a rear inhaul cable counter-force transmission system is formed. The problem that a ground anchor cannot be arranged is solved, the construction technology is mature, safety is high, and the bridge construction requirements of similar working conditions can be met.
本发明涉及一种钢结构桥梁安装自锚式扣塔施工方法。本发明包括前拉索、扣塔、扣塔锚梁、后拉索、后锚点、钢锚箱、钢绞线、钢锚梁和P锚等几部分。扣塔设置于桥梁承台上并于钢梁刚性连接，扣塔锚梁设置于扣塔上和扣塔形成一个整体，两端分别设置前拉索、后拉索锚固装置，用于调整拉索索力和桥梁线型。后锚点设置于钢梁端横梁外部，用于锚固后拉索，钢锚箱设置于钢梁端横梁内部，用于锚固钢绞线。P锚在桥墩承台施工时预埋在承台上，钢锚梁与预埋P锚连接，钢绞线一端穿过钢梁底板预设的孔洞与钢锚箱锚固，另一端与钢锚梁锚固，形成后拉索反力传递体系。本发明解决了无法设置地锚问题，施工工艺成熟、安全性高，能够满足类似工况的桥梁施工要求。
