Cast-in-place box girder construction method
The invention relates to a cast-in-place box girder construction method, and belongs to the technical field of bridge construction. S2, concrete is poured into the river slope and the area from the two ends of the river to the pier body flat area; s3, steel pipe piles are anchored in the center of the river channel in the water flow direction; s4, a temporary horizontal bearing platform is erected at the tops of the steel pipe piles, symmetrical bevel edge bearing platforms are erected at the two ends of the horizontal bearing platform, the horizontal bearing platform and the bevel edge bearing platforms at the two ends form a river channel foundation, and the bevel edge bearing platforms extend to the poured flat area and are connected with the flat area; s5, a support is built on the river foundation and the flat area, and a bottom die is installed; and S6, support prepressing, box girder formwork and steel bar mounting, steel pipe pile anchoring in the river channel, horizontal bearing platform serving as a base point, beveled bearing platforms are gradually built towards the two sides, the beveled bearing platforms are connected with the horizontal bearing platform and the flat area, the supports located in the river channel area can be dispersed to the two ends of the river channel, the stability of the river channel foundation is further enhanced, and meanwhile the river is not affected.
本发明涉及一种现浇箱梁施工方法，属于桥梁施工技术领域，包括S1：勘测河道地质情况；S2：对河道边坡以及河道两端至墩身平坦区域分别浇筑混凝土；S3：在河道中心沿着水流方向锚固钢管桩；S4：在钢管桩顶部搭设临时水平承台，在水平承台两端搭建对称的斜边承台，水平承台与两端的斜边承台组成河道地基，斜边承台延伸至浇筑完成的平坦区域，并与平坦区域连接；S5：在河道地基和平坦区域搭建支架、安装底模；S6：支架预压、箱梁模板及钢筋安装，在河道内锚固钢管桩，以水平承台为基点，逐渐向两边搭建斜边承台，斜边承台连接水平承台和平坦区域，可以将位于河道区域的支架分散至河道两端，进一步增强河道地基的稳定性，同时还不会影响河流。
