桥梁伸缩缝对公路桥梁来说,是一个不可缺少的设备,之所以需要这个设备,主要是因为桥梁会随着温度的变化发生变化,长期下去,桥梁梁端就会出现位移,为了能够让车辆在运行时,适应这种位移变化,就需要安装梁伸缩缝设备,但是因为某些原因,该设备不仅没有发挥其应有的作用,还使桥面出现了跳车的问题。首先介绍了公路桥梁伸缩缝;其次概述了公路桥梁伸缩缝处出现跳车的原因;最后探讨了其防治措施,希望能够为公路建设工程的发展提供借鉴。 Bridge expansion joints for highway bridges, is an indispensable equipment, the reason for the need for this equipment, mainly because the bridge will change with the temperature changes in the long run, there will be displacement of the bridge beam end, in order to allow vehicles In operation, to adapt to this displacement change, you need to install the beam expansion joint equipment, but for some reason, not only did not play its due role in the equipment, but also to bridge the problem of jumping. Firstly, the expansion joints of highway bridges are introduced. Secondly, the reasons for the jumps of highway bridge expansion joints are summarized. Finally, the prevention and control measures are discussed, hoping to provide reference for the development of highway construction projects.
