Frame beam dismantling construction method
The invention discloses a frame beam dismantling construction method. The frame beam dismantling construction method comprises the following steps that firstly, a lowering system is erected; a lowering system is erected above the frame beam, a supporting point of the lowering system is arranged at the top of a pier, and the lowering system is used for transporting or lowering a to-be-dismantled frame beam section; 2, traffic conversion and protection shed installation; a protective shed is installed at the position of one half frame beam, the other half frame beam is closed to serve as a construction channel, and road traffic is converted into the protective shed; 3, dismantling the frame beam in a span mode; the frame beams are cut span by span and section by section according to a set sequence, and the frame beams are dismantled span by span and section by section according to the sequence by adopting a lowering system; fourthly, the lowering system is dismantled; and fifthly, the bridge piers are dismantled, and dismantling work of the frame beam is completed. The frame beam demolition construction method can better adapt to a bridge structure and a construction environment, and rapid demolition construction is achieved.
本发明公开了一种框架梁拆除施工方法，包括如下步骤：步骤一：下放系统搭设；在框架梁上方搭设下放系统，其支撑点设置于桥墩顶部，所述下放系统用于运输或下放待拆除的框架梁段；步骤二：交通转换、防护棚安装；在其中半幅框架梁的位置安装防护棚，另外半幅框架梁封闭作为施工通道，将道路交通转换至防护棚内；步骤三：框架梁分跨拆除；按设定的顺序逐跨逐段切割框架梁，并采用下放系统按顺序逐跨逐段拆除框架梁；步骤四：拆除下放系统；步骤五：拆除桥墩，完成框架梁的拆除工作。本发明的框架梁拆除施工方法能够更好的适应桥梁结构和施工环境，实现快速拆除施工。
