Construction method for prolonging radial width of highway bridge
The invention discloses a construction method for prolonging the radial width of a highway bridge, and the method comprises the following steps: 1, firstly, carrying out the comprehensive investigation of an existing highway bridge, detecting the bearing capacity of the bridge through equipment, and confirming a broadening design standard according to the data; 2, after detection is completed, disassembling handrails on the two sides of the existing bridge and pedestrian crossing plates; and 3, synchronously conducting construction at the two ends of the bridge according to the widening design standard, firstly, arranging a guide rail on one side of the bridge, and then hoisting the bearing device to the guide rail through a crane. Widening work of the highway bridge floor is completed through the movable bearing device, and thus the problems that according to the existing highway, the cantilever is usually erected on the bridge to hoist the mold used for widening the bridge, the bridge floor widening is achieved in a concrete pouring mode, but the cantilever erecting process is tedious, the construction efficiency is affected, and in the whole construction process, the number of lifting elements is large, and the falling danger is likely to happen.
本发明公开了一种延长高速公路桥梁径向宽度的施工方法，包括以下步骤：步骤1：首先对现有高速公路桥梁进行全面调查，利用设备对桥梁承载能力进行检测，并根据数据确认拓宽设计标准；步骤2：检测完毕后，拆除现有桥梁两侧的栏杆以及人行横道板；步骤3：按照拓宽设计标准在桥梁的两端同步进行施工，首先在桥梁的一侧布设导轨，之后依靠吊机将承载装置吊运至导轨上。其实现了依靠移动式承载装置完成高速公路桥面的拓宽工作，从而有效的避免了现有高速公路通常采用在桥上架设悬臂来吊运拓宽桥梁所用的模具，并依靠混凝土浇筑的方式实现桥面拓宽，但其架设悬臂流程较为繁琐，影响施工效率，且整个施工流程吊运元件较多，易发生坠落危险的问题。
