Pushing construction method for bridge erection
The invention is applicable to the technical field of bridge erection, and provides a pushing construction method for bridge erection. The method comprises the following steps: erecting a pushing platform; conveying a front guide beam to a designated position and connecting with a first span main arch, and completing steel guide rail laying below the first span main arch and combination of the steel guide rail and the first span main arch; dragging the front guide beam and the first span main arch to move forwards, and allowing the first span main arch to push the first span main arch crown tothe first permanent pier and the second permanent pier after passing through the first temporary pier; combining the second span main arch with the steel guide rail and connecting the second span main arch with the first span main arch; and allowing the first span main arch to be pushed to fall on the second permanent pier and the third permanent pier through the second temporary pier, and allowing the second span main arch to fall on the first permanent pier and the second permanent pier. Compared with a full framing construction mode and a stiff skeleton construction mode, the constructionprogress can be accelerated, the stress reasonability of the structure can be guaranteed, and the better economical efficiency is achieved under the specific conditions that the construction period isshort and the construction site is wide.
本发明适用于桥梁架设技术领域，提供了一种用于桥梁架设的顶推施工方法，包括搭设顶推平台；将前导梁运送至指定位置并与第一跨主拱联结同时完成第一跨主拱下方的钢导轨铺设以及钢导轨与第一跨主拱的结合；牵引前导梁和第一跨主拱前进，第一跨主拱通过第一临时墩后将第一跨主拱顶推至第一永久墩和第二永久墩上；将第二跨主拱与钢导轨结合并使第二跨主拱与第一跨主拱联结；顶推第一跨主拱通过第二临时墩落拱于第二永久墩和第三永久墩上，第二跨主拱落拱于第一永久墩和第二永久墩上。本发明相对于满堂支架施工及劲性骨架施工方式既能加快施工进度，又能保证结构受力合理性，本发明在工期紧张而施工场地较为宽裕的特定情况下，具有更好的经济性。
