Construction method for dismantling overpass bridge on expressway
The invention discloses a construction method for dismantling an overpass bridge on an expressway, relates to the technical field of overpass bridge dismantling, and solves the problems that when an existing overpass bridge is cut, a high-speed bridge at the bottom is easily damaged, and generated fragments are not easy to clean and transport. B, punching is conducted; c, mounting a positioning column and a positioning plate; d, foundation treatment; e, erecting a scaffold under the high-speed bridge; f, erecting a scaffold on the high-speed bridge; g, scaffolds on the two sides of the high-speed bridge are erected; h, the guardrails and the flange plates are dismounted; i, hoisting a flange plate; j, cutting and hoisting concrete blocks; k, the scaffold is dismantled, the cut concrete blocks are positioned by the positioning columns, so that the cut concrete blocks are not prone to falling onto the expressway at the bottom, the crane is connected to the tops of the positioning columnsto hoist the concrete blocks during transferring, the shapes of the concrete blocks are more regular, and transferring is convenient and quick.
本发明公开了一种在高速公路上拆除跨线桥施工方法，涉及跨线桥拆除的技术领域，解决了现有跨线桥切割时容易对底部的高速桥造成损伤并且产生的碎块不容易清理运输的问题，其技术方案要点是包括以下步骤：a.测量划线；b.打孔；c.定位柱和定位板安装；d.地基处理；e.高速桥下脚手架搭设；f.高速桥上脚手架搭设；g.高速桥两侧脚手架搭设；h.拆除护栏和翼缘板；i.吊装翼缘板；j.混凝土块切割吊装；k.拆除脚手架，定位柱对切割下来的混凝土块进行定位使其不容易掉落到底部的高速公路上，转移的时候起重机连接到定位柱顶部对混凝土块进行吊装，混凝土块形状更加规则且转移方便快捷。
