Overwater segmental beam lifting station and closure construction method
The invention relates to an overwater segmental beam lifting station and a closure construction method, and relates to the technical field of bridge segmental beam closure, the overwater segmental beam lifting station comprises piers and bridge frames arranged on the piers, closure sections are formed between the bridge frames, and support columns used for assisting in supporting the bridge frames are arranged at the positions, close to the closure sections, of the piers; hoisting trusses are arranged on the bridge frames on the two sides of the closure section respectively, center hole jacks are arranged on the hoisting trusses, hoisting steel ropes are movably installed on the center hole jacks, and the ends, facing the water surface, of the hoisting steel ropes on the two sides are jointly connected with a stabilizing frame used for being connected with the segmental beams; and an adjusting bracket is arranged below the hoisting truss. The method can effectively solve the problem that navigation is seriously influenced by slow construction progress of the closure section of the span bridge, can realize integral lifting and accurate positioning of the segmental beam, and improves the safety and efficiency of closure construction of the steel structure bridge.
本申请涉及一种水上节段梁提升站及合拢施工方法，涉及桥梁节段梁合拢技术领域，其包含桥墩及设置在桥墩上的桥梁架，桥梁架之间形成有合拢段，桥墩靠近合拢段位置处设置有用于辅助支撑桥梁架的支架柱，位于合拢段两侧的桥梁架上分别设置有吊装桁架，吊装桁架上设置有穿心千斤顶，穿心千斤顶上活动安装有吊装钢绳，两侧吊装钢绳朝水面的端部共同连接有用于连接节段梁的稳定框；吊装桁架的下方设置有调整牛腿。本申请能够有效解决跨度桥梁合拢段施工进度缓慢严重影响通航的问题，能够实现节段梁的整体提升及精准定位，提高了钢结构桥梁合拢施工的安全及效率。
