Jacking and lifting combined large-span arch structure construction method
The invention discloses a jacking and lifting combined large-span arch structure construction method. The method comprises the following steps that S1, a part of arch structure is assembled on the ground; s2, the assembled partial arch structure is jacked; s3, after jacking in place, splicing with the remaining arch structure into a whole; s4, the assembled whole arch structure is lifted; and S5, after lifting in place, structure installation is carried out. The jacking frame is used as a lifting supporting frame, the using amount of standard knots can be effectively saved, the standard knots are assembled into a whole after being jacked in place, the high-altitude operation amount can be greatly reduced, the safety problem of high-altitude operation in the installation process is effectively solved, the using amount of jacks can be saved, and meanwhile compared with a secondary lifting method, the method does not need to dismantle the lifting knots, and the cost is reduced. The arch structure can be lifted in place by directly utilizing the lifting device, so that tool materials and lifting sections for lifting are reduced, the time for dismounting the lifting sections after secondary lifting is saved, and the construction efficiency is improved.
本发明公开了一种顶升、提升结合的大跨度拱形结构施工方法，包括：步骤如下：S1：地面拼装部分拱形结构；S2：拼装好的部分拱形结构进行顶升；S3：顶升到位后，与剩余的拱形结构拼装为整体；S4：拼装完的整体拱形结构进行提升；S5：提升到位后进行结构安装。利用顶升架充当提升支撑架，能有有效节省标准节的用量，顶升到位后组装成整体，可以大大减少高空作业量，有效解决安装中高空作业的安全问题，还能节省千斤顶的用量，同时相比二次提升方法而言，本方法不用进行提升节拆除，可以直接利用提升装置把拱形结构提升到位，从而减少提升用的工装材料和提升节，而且省去了第二次提升后拆除提升节的时间，提高施工效率。
