Construction method of highway-crossing inclined-leg rigid frame overpass
The invention discloses a construction method of a highway-crossing inclined-leg rigid frame overpass. The construction method sequentially comprises the steps of leveling a foundation according to asupport design scheme, and erecting an inclined leg full framing and steel pipe stand column few supports for bearing a beam body; mounting an inclined leg part bottom die and a beam body part steel die plate; simulating a construction load to pre-press the bracket, monitoring and recording according to specifications, and measuring elastic deformation and non-elastic deformation of the bracket; accurately adjusting the elevation of the bottom die according to the pre-pressing data; binding inclined leg reinforcing steel bars, and installing inclined leg side molds and cover molds; binding beam body web reinforcing steel bars, and installing a web inner side mold; erecting an inner top plate support, and installing a top plate formwork; binding top plate and wing plate steel bars; pouringinclined leg concrete, and pouring beam body concrete after the inclined leg concrete is initially set; through the combination of the inclined leg full framing and the few steel pipe stand columns, the problems that the high-speed-crossing construction full framing cannot guarantee road passing, and the single few steel pipe stand columns cannot meet inclined leg construction are solved.
本发明专利公开了一种跨高速斜腿刚构天桥施工方法，依次包括步骤：按支架设计方案平整处理地基基础，搭设斜腿部满堂支架和承载梁体的钢管立柱少支架；安装斜腿部分底模和梁体部分钢模板；模拟施工荷载对支架进行预压，按规范进行监测记录，测得支架弹性变形和非弹性变形；按预压数据精确调整底模标高；绑扎斜腿钢筋，安装斜腿侧模及盖模；绑扎梁体腹板钢筋，安装腹板内侧模；搭设内顶板支架、安装顶板模板；绑扎顶板、翼板钢筋；浇筑斜腿混凝土，待斜腿混凝土初凝后，浇筑梁体混凝土；本发明通过斜腿部满堂支架、钢管立柱少支架的结合，解决了跨高速施工满堂支架无法保证道路通行，单独钢管立柱少支架无法满足斜腿施工的问题。
