Small box girder bridge deck precast concrete guardrail mounting system and mounting method
The invention discloses a small box girder bridge deck precast concrete guardrail mounting system and method, and relates to the technical field of bridge engineering, in particular to a bridge body, a carrying vehicle and at least two guide rails; the bridge body is formed by erecting simply-supported prefabricated small box girders, and shear steel bars are arranged in the bridge deck area of the bridge body in a protruding mode. The guide rails are arranged on the bridge floor area in parallel in pairs at intervals and staggered with the shear steel bars; a chassis of the carrying vehicle is provided with at least two rows of rail wheels, and the rail wheels are in rolling fit with the guide rails in a one-to-one correspondence manner; the carrying vehicle is used for moving in the bridge floor area through rolling of the rail wheels along the guide rails so that the prefabricated concrete guardrail body can be conveyed to the bridge floor area to be installed. The installation system can solve the technical problems that installation construction of the anti-collision guardrail of the bridge needs to be carried out after bridge deck pavement is completed, a temporary guardrail is usually adopted to enclose a construction site before the anti-collision guardrail is installed, the safety protection performance of the temporary guardrail is common, and site safety accidents are prone to being caused.
本申请公开了一种小箱梁桥面预制混凝土护栏安装系统及安装方法，涉及桥梁工程技术领域，具体包括桥梁本体、搬运车辆和至少两条导向轨道；桥梁本体通过简支预制小箱梁架设而成，桥梁本体的桥面区域凸设有剪力钢筋；导向轨道两两平行地间隔设置于桥面区域并与剪力钢筋交错设置；搬运车辆的底盘设有至少两排轨道轮，轨道轮一一对应滚动配合于导向轨道上；搬运车辆用于通过轨道轮沿导向轨道的滚动而在桥面区域移动，以将预制混凝土护栏本体运送至桥面区域进行安装。该安装系统可解决桥梁防撞护栏的安装施工需要在桥面铺装完成后方能进行，而在安装防撞护栏前通常采用临时护栏对施工现场进行围蔽，其安全防护性能一般，易造成现场安全事故的技术问题。
