Accurate positioning construction method suitable for large-span steel truss arch bridge main pier support installation
The invention discloses an accurate positioning construction method suitable for mounting of a large-span steel truss arch bridge main pier support, which comprises the following steps of: S1, pouring a support padstone, and reserving a padstone post-pouring layer with a set thickness; s2, a temporary steel base plate with the set thickness is laid on the support cushion stone; s3, vertical and plane position adjusting devices are arranged on the support cushion stone; s4, the hoisting support is supported on the temporary steel base plate; s5, the vertical elevation of the support is adjusted through a vertical position adjusting device, meanwhile, the temporary steel base plate is pulled out, and a gap is formed between the support and the support padstone; s6, the plane position of the support is adjusted through a plane position adjusting device; s7, the support and the support padstone are connected into a whole through foundation bolts, and then a padstone post-pouring layer is cast in situ; and S8, the steel beam joint is jacked, the support is supported on the support padstone, and support installation is completed. The method has the advantages of being simple in process, reliable in quality, capable of saving the construction period, good in economical efficiency, good in application prospect and the like.
本发明公开了一种适用于大跨度钢桁拱桥主墩支座安装的精确定位施工方法，包括如下步骤：步骤S1：浇筑支座垫石，并预留设定厚度的垫石后浇层；步骤S2：在支座垫石上铺设设定厚度的临时钢垫板；步骤S3：在支座垫石上设置竖向及平面调位装置；步骤S4：吊装支座支撑于临时钢垫板上；步骤S5：通过竖向调位装置调整支座的竖向标高，同时抽出临时钢垫板，支座与支座垫石之间具有间隙；步骤S6：通过平面调位装置调整支座平面位置；步骤S7：将支座与支座垫石通过地脚螺栓连接为一体，然后现浇垫石后浇层；步骤S8：起顶钢梁节点，将支座支撑在支座垫石上，完成支座安装。本发明具有工艺简单、质量可靠、节省工期、经济性好、应用前景好等优点。
