Self-climbing support structure for bridge jacking and jacking method thereof
The invention relates to a self-climbing support structure for bridge jacking and a jacking method thereof. The support structure comprises steel pipe stand columns and jacking supports, wherein the steel pipe stand columns are arranged at intervals and formed by vertically splicing stand column sections, the jacking supports are arranged on the steel pipe stand columns, and bridge jacking oil cylinders are arranged at the tops of the steel pipe stand columns; the jacking support comprises an upper cross beam support and a lower cross beam support which are movably arranged in a lifting mode, a vertical telescopic oil cylinder is arranged between the upper cross beam support and the lower cross beam support in the vertical direction, supporting pieces are hinged to the side faces of all the stand column sections of the steel pipe stand column, and when the supporting pieces are overturned in place towards one side, the lower cross beam support is supported. The movable lifting of the upper cross beam bracket and the lower cross beam bracket is not interfered when the upper cross beam bracket and the lower cross beam bracket are overturned in place towards the other side; the upper beam support is fixedly connected with a bridge jacking oil cylinder, and a lifting tool used for lifting the stand column section is arranged on the circumferential face of the upper beam support. During jacking, the support structures A and B are arranged below the bridge, the support structures A and B alternately and automatically climb, the stand column sections are additionally arranged in a suspended mode to achieve bridge jacking operation, and the construction efficiency is high.
本发明涉及一种桥梁顶升用自爬升支架结构及其顶升方法，该支架结构包括间隔排列的由立柱段竖向拼接而成的钢管立柱，设置于钢管立柱的顶升支架，各钢管立柱顶部均设置桥梁顶升油缸；顶升支架包括活动升降设置的上横梁支架和下横梁支架，上横梁支架与下横梁支架的竖向间设有竖向伸缩油缸，钢管立柱的各立柱段侧面铰接设有支撑件，当支撑件朝一侧翻转到位时对下横梁支架形成支撑，朝另一侧翻转到位时对上横梁支架和下横梁支架的活动升降无干涉；上横梁支架固定连接桥梁顶升油缸，上横梁支架的周面设有用于吊装立柱段的吊具。顶升时，桥梁下方设置A、B组支架结构，采用A、B组支架结构交替自动爬升并悬吊加装立柱段实现桥梁顶升作业，施工效率高。
