Vertical stepping lifting installation method for tie beam of large-span channel-crossing tied-arch bridge
The invention provides a large-span channel-crossing tied-arch bridge tie beam vertical stepping lifting installation method, which comprises the following steps of: 1, component connection: connecting tie beam connecting devices of a plurality of lifting devices to tie beam pre-supporting connecting pieces respectively, connecting the upper ends of tie beams with arch ribs, and enabling the tie beams to be in a horizontal state at the moment; secondly, the straining beam is lifted, the hollow jack is made to extend, the lower suspension nut is rotated to abut against the bottom wall, the hollow jack is made to contract, the upper suspension nut is rotated to abut against the open center jack, and the second step is repeated till the height of the straining beam meets the requirement; and thirdly, the straining beam and the arch rib are connected together through the nymph slings, and the lifting device is dismantled between the straining beam and the arch rib. The lifting device has the advantage that the position of the straining beam can be conveniently and reliably lifted to meet the requirement, and the problem that the lifting cost is high due to the fact that supporting platform supporting and lifting equipment is lapped in water for straining beam lifting and locking in the prior art is solved.
本发明提供了一种大跨度跨航道系杆拱桥系梁竖向步进提升安装方法，第一步、部件连接：将若干提升装置的系梁连接装置各连接在一个系梁预支连接件，将系杆的上端同拱肋连接在一起，此时系梁处于水平状态；第二步、系梁提升：使空心千斤顶伸长，转动下悬挂螺母到抵接在所述底壁上，使空心千斤顶收缩，转动上悬挂螺母到抵接在开心千斤顶上，重复第二步直到系梁的高度符合要求；第三步、将系梁和拱肋通过若果吊索连接在一起，将提升装置从系梁和拱肋之间拆除。本发明旨具有能够方便可靠的使得系梁的位置提升到符合要求的优点，解决了现有的在水里搭接支撑平台支撑吊装设备进行系梁提升锁导致的吊装成本高的问题。
