Transverse safety performance improving and transforming method for bridge
The invention belongs to the technical field of bridge construction, and particularly relates to a bridge transverse safety performance improving and transforming method which comprises the following steps that A, first L-shaped steel is anchored on the side surface of an integral box girder; b, a first spiral spring is fixed to a web of the first L-shaped steel; c, second L-shaped steel is anchored on the side surfaces of the check blocks on the two sides of the box girder, and first spiral springs are fixed; and D, a second spiral spring is fixed between the box girder bottom plate and the upper surface of the abutment cover beam. According to the transformation method, the construction procedure is simple and rapid, component stress is definite, and the system is safe and stable; while normal operation of the single-column pier bridge is ensured, the overall disaster prevention and resistance level of the bridge is improved, and bridge potential safety hazards caused by car unbalance loading and earthquake loads are prevented and resolved.
本发明属于桥梁施工技术领域，具体来说，是一种桥梁横向安全性能提升改造方法，包括以下步骤：A、在整体式箱梁侧表面锚固第一L型钢；B、在第一L型钢的腹板上固定第一螺旋弹簧；C、在箱梁两侧的挡块侧表面锚固第二L型钢并固定第一螺旋弹簧；D、在箱梁底板与桥台盖梁上表面之间固定第二螺旋弹簧。本发明改造方法，施工工序简单、快速，构件受力明确，体系安全稳定；在确保独柱墩桥梁正常运营的同时，提升桥梁整体防灾抗灾水平，防范化解汽车偏载及地震荷载引起的桥梁安全隐患。
