Construction method for dismantling existing frame bridge through rope saw reverse cutting method
The invention discloses a construction method for dismantling an existing frame bridge through a rope saw reverse cutting method. The method comprises the steps: determining a cutting line position; drilling side walls and a top plate; installing a rope saw and a diamond rope; cutting the side wall; cutting the top plate; breaking the splayed feet below the side walls, and jacking the new frame bridge. The construction method provided by the invention is scientific and reasonable, effectively solves the problem of great influence on the existing roadbed when the existing frame bridge is cut bya wire saw, and avoids the defects of the conventional method. According to the method, a rope saw reverse cutting construction process is adopted, a rope saw must be laterally installed on a side wall before the side wall is cut, the side wall is cut before a top plate rope saw starts to be cut, cyclic operation of equipment is closely arranged when each ring of cutting is conducted, and therefore the method has the advantage of being compact in operation. Meanwhile, the construction process is simple and convenient to operate, and the safety of construction operation is enhanced. The construction risk is reduced, and the construction efficiency is improved.
一种利用绳锯反向切割法拆除既有框架桥的施工方法。其包括确定切割线位置；边墙及顶板钻孔；安装绳锯及金刚石绳索；切割边墙；切割顶板；破碎边墙下八字脚及新框架桥顶进等步骤。本发明提供的的施工方法科学、合理、有效地解决了采用绳锯切割既有框架桥对既有路基影响大的问题，避免了传统做法的缺点。采用了绳锯反切的施工工艺，边墙切割前必须将绳锯侧向安装在边墙上，并在顶板绳锯切割开始前完成边墙的切割，每一环切割进行时设备的循环操作紧密安排，从而使得本方法具有操作紧凑的特点。同时施工过程操作简单方便，施工作业的安全性得到了增强。降低了施工风险，提高了施工效率。
