Urban bridge demolition method
The invention relates to the technical field of urban elevated bridge dismantling, in particular to an urban bridge dismantling method. The method comprises the following steps that S1, before construction, all splitting units are delimited on the top face of a beam body according to the set dismounting length; s2, according to the set position, a hole is drilled in the flange plate suspension device main frame; and S3, a flange plate hoisting ring and a horizontal pull wire ring are implanted, and meanwhile, rear anchor bars are implanted into the rear anchor bar holes. According to the urban bridge demolition method provided by the invention, the number of measure projects such as erection and demolition of a support system of a bridge flange plate part and a support system foundation is completely canceled, the expense is reduced, the progress of demolition operation is accelerated, the construction period is shortened, and the management cost is saved; the number of high-altitude operation personnel is reduced, the high-altitude operation time is shortened, the land of the central separation strip of the beam bottom is fully utilized, the existing lane is occupied only during hoisting operation, the road occupation range is greatly reduced, the road occupation construction time is greatly shortened, and urban road traffic jam is avoided.
本发明涉及城市高架桥梁拆除技术领域，尤其涉及一种城市桥梁拆除方法。步骤如下：S1、施工之前，先按照既定的拆除长度，在梁体顶面划定各个拆分单位；S2、按照既定位置，在翼缘板悬吊装置主架上钻设孔洞；S3、植入翼缘板吊装环、水平拉线环，同时在后锚筋孔中植入后锚筋。本发明提供的一种城市桥梁拆除方法，完全取消了桥梁翼缘板部分的支撑体系搭设、拆除及支撑体系基础等措施工程数量，减少费用支出，加快了拆除作业的进度，缩短了施工周期，节约了管理费；缩减了高空作业人员数量和高空作业时长，充分利用了梁底中央分隔带的土地，仅在吊装作业时占用既有车道，大大缩减了占道范围和占道施工时间，避免了城市道路交通堵塞。
