Buoyancy jacking device for bridge floor of water-crossing bridge and using method of buoyancy jacking device
The invention relates to a buoyancy jacking device for a water-crossing bridge deck and a using method of the buoyancy jacking device, and belongs to the technical field of bridge construction. The device comprises a longitudinal limiting bin, a transverse limiting bin and a buoyancy jacking column. The longitudinal limiting bin comprises a water drainage bin, the water drainage bin is of a box body structure, and a bridge floor limiting device is installed on the longitudinal limiting bin; longitudinal limiting bins are connected to the two ends, in the length direction, of the transverse limiting bins correspondingly. The transverse limiting bin is provided with a buoyancy jacking column hole which is through in the vertical direction. The buoyancy jacking column penetrates through the buoyancy jacking column hole and moves up and down in the buoyancy jacking column hole in the vertical direction. And an inflatable airbag is arranged at the bottom end of the buoyancy jacking column. The invention provides a special bridge floor jacking device and a special bridge floor jacking method for jacking transformation construction of a water-crossing bridge; a bridge floor limiting device is used above to restrain the bridge floor; and the transverse limiting bin with the same width as the pier is utilized below, so that the transverse limiting bin and the two longitudinal limiting bins are close to the pier from three directions, and the problem that a jacking transformation construction platform is difficult to install on the water surface is solved.
本发明涉及一种跨水桥梁桥面的浮力顶升装置及其使用方法，属于桥梁施工技术领域。装置包括：纵向限位仓、横向限位仓和浮力顶升柱；纵向限位仓包括排水仓，水仓为箱体结构，纵向限位仓上安装有桥面限位装置；横向限位仓的长度等于桥墩宽度，横向限位仓长度方向的两端分别连接有纵向限位仓；横向限位仓设置有竖直方向贯通的浮力顶升柱孔；浮力顶升柱穿过浮力顶升柱孔，在浮力顶升柱孔中沿竖直方向上下移动；浮力顶升柱的底端设置有充气气囊。本发明为跨水桥梁的顶升改造施工提供了专用的桥面顶升装置与桥面顶升方法；在上方利用桥面限位装置约束桥面；在下方利用与桥墩宽度相同的横向限位仓，使横向限位仓与两个纵向限位仓从三个方向靠紧桥墩，解决了在水面上难以安装顶升改造施工平台的问题。
