Height-adjustable emergency bridge pier and emergency bridge
The invention discloses a height-adjustable emergency bridge pier and an emergency bridge, the height-adjustable emergency bridge pier comprises a multi-stage telescopic bridge pier, a bottom plate and a top plate, the multi-stage telescopic bridge pier is arranged between the bottom plate and the top plate which are parallel to each other, and a plurality of limiting force transmission screws are distributed between the bottom plate and the top plate; the multi-stage telescopic pier comprises a plurality of pier cylinder columns which are sequentially nested, the upper end and the lower end of the pier cylinder column on the outermost layer are connected with a bottom plate and a top plate respectively, a piston rod is sleeved with the pier cylinder column on the innermost layer, the outer end of the piston rod is arranged downwards, a first through hole is formed in the bottom plate, and the first through hole is formed under the multi-stage telescopic pier. The movable end of the multi-stage telescopic pier can penetrate through the first through hole of the bottom plate to stretch out of the lower portion of the bottom plate, and the multi-stage telescopic pier is communicated with a hydraulic system. The storage space can be saved, and transportation is convenient; installation is more convenient and rapid, the construction period of rush-repair bridges is shortened, the engineering construction cost is reduced, repeated use is achieved, and parts are convenient to replace.
本发明公开了一种高度可调节的应急桥墩及应急桥梁，高度可调节的应急桥墩包括多级伸缩桥墩、底板和顶板，多级伸缩桥墩设置于相互平行的底板和顶板之间，底板和顶板之间分布有多个限位传力螺杆；多级伸缩桥墩包括依次嵌套的多个桥墩缸柱，最外层的桥墩缸柱的上端和下端分别与底板和顶板连接，最内层的桥墩缸柱内套设有活塞杆，活塞杆的外端朝下布置，底板上设有第一通孔，第一通孔布置于多级伸缩桥墩的正下方，多级伸缩桥墩的活动端可穿过底板的第一通孔伸出于底板下方，多级伸缩桥墩连通有液压系统。本发明能节省了储存空间，运输方便；安装更加方便迅速，减少抢修桥梁施工周期，减少工程建设成本，可重复使用，部件更换方便。
