Truss integral lifting type bridge high pier creeping formwork device and construction method
The invention discloses a truss integral lifting type bridge high pier creeping formwork device and a construction method. Climbing rails are arranged on four embedded climbing rail fixing pieces at the rectangular corners of a bridge abutment; a top truss operating platform is arranged at the upper end of each climbing rail, and climbing rail anchor bolts are arranged at the lower end; an outer formwork is arranged between every two adjacent climbing rails in the circumferential direction; an inner formwork is arranged on the inner side of the outer formwork; an outer mold truss operating platform is arranged on the outer side of each climbing rail; a hydraulic jacking mechanism is arranged between the outer mold truss operating platform and the climbing rails; the outer mold truss operating platform is connected with the top truss operating platform through a first hydraulic lifting mechanism; an inner mold truss operating platform is arranged on the inner side of the inner formwork,and the inner mold truss operating platform is connected with the top truss operating platform through a second hydraulic lifting mechanism; the construction method comprises the steps that the climbing rails and the top truss operating platform are installed; the outer formwork and the outer mold truss operating platform are lifted, and pier body solid transition section concrete is poured; theclimbing rails are jacked; the inner formwork and an inner mold truss operating platform are installed; standard sections of the bridge pier body are constructed; and the whole structure is dismantled.
一种桁架整体提升式桥梁高墩爬模装置及施工方法，桥梁墩台矩形角上的四个预埋爬轨固定件上均设有爬轨，爬轨的上端设有顶部桁架操作平台、下端设有爬轨锚固螺栓，周向相邻两爬轨之间设有外模板，外模板内侧设有内模板，爬轨外侧设有外模桁架操作平台，外模桁架操作平台与爬轨之间设有液压顶升机构，外模桁架操作平台通过第一液压提升机构与顶部桁架操作平台相联，内模板内侧设有内模桁架操作平台，内模桁架操作平台通过第二液压提升机构与顶部桁架操作平台相联；施工方法包括安装爬轨及顶部桁架操作平台；提升外模板及外模桁架操作平台并浇筑墩身实心过渡段混凝土；爬轨顶升；安装内模板和内模桁架操作平台；桥梁墩身标准节段施工；整套结构拆除。
