Ultrahigh single-column pier reinforcing and maintaining method
The invention relates to an ultrahigh single-column pier reinforcing maintenance method, which comprises the following steps: firstly, arranging a hanging basket construction platform by utilizing a beam bottom space, not occupying an expressway ground road, reducing the influence of construction on expressway traffic, and mounting and dismounting a construction operation platform through the procedures of lifting point mounting, lifting lug mounting, hanging basket mounting and lifting, hanging basket locking and the like; by adopting the measure of adjusting the embedded steel bar angle, theproblems of dense arrangement of steel bars on a cross beam and a bent cap and high anchor bolt construction positioning difficulty in dry drilling construction are effectively solved, and the problem that skew bridge pier steel plate anchor bolts cannot be mounted is also solved; in the installation process of the anti-overturning anchor bolt system, by adjusting the construction sequence of part of steel structure machining, conflict between anchor plate installation and upper and lower anchor plate rib plates and steel box girders can be avoided in time; by adjusting the installation sequence of the upper and lower anchor plates, common problems that special-shaped pier bolt holes are difficult to install and original bridge displacement is limited are avoided; by installing an anti-overturning monitoring device, the stability of the girder bridge structure in the operation stage can be mastered in real time.
本发明涉及一种超高独柱墩加固维修方法，首先，利用梁底空间设置吊篮施工平台，不占用高速地面道路，减少施工对高速公路交通的影响，通过吊点安装、吊耳安装、吊篮安装与提升、吊篮锁定等工序，完成施工作业平台的安装和拆除；通过采取植筋角度调整的措施，有效解决干钻法施工中横梁及盖梁上钢筋布置密集，锚栓施工定位难度较大问题，也克服斜交桥墩钢板锚栓无法安装难题；在抗倾覆锚栓系统安装流程中，通过调整部分钢结构加工的施工顺序，能够及时避免锚板安装与上下锚板肋板、钢箱梁冲突；通过调整上下锚板安装顺序，避免异形桥墩栓孔安装困难，限制原有桥梁位移等常见问题；通过安装抗倾覆监控装置，实现对运营阶段梁桥结构稳定性的实时掌握。
