Electrician evacuation passage for bridge expansion joint
The invention provides an electrician evacuation passage for a bridge expansion joint. The electrician evacuation passage is characterized in that a main bridge steel box girder bottom plate and an approach bridge steel box girder bottom plate are provided with sliding grooves formed in the expansion and contraction direction of the expansion joint, the bottom of an evacuation passage bottom plateis provided with sliding blocks matched with the sliding grooves, the sliding blocks are placed in the sliding grooves and slide along with the expansion and contraction of the bridge expansion joint, and safety railings are installed at the two ends of the evacuation passage bottom plate. According to the electrician evacuation passage, the expansion and contraction of the two ends of the bridgeexpansion joint along with the temperature change in four seasons are not influenced, and meanwhile, the problems about safe passing and evacuation of inspection personnel for electrical equipment orother equipment can be effectively solved. The electrician evacuation passage is safe, reliable, simple, effective and high in cost performance, and has higher practical and promotional value in theconstruction and maintenance work of similar long bridges or large bridges crossing rivers.
本发明提供了一种用于桥梁伸缩缝处的电工疏散通道，其特征在于：主桥钢箱梁底板和引桥钢箱梁底板上安装有沿伸缩缝伸缩方向设置的滑槽，疏散通道底板底部安装有与所述滑槽配合的滑块；滑块放入到滑槽内随桥梁伸缩缝的伸缩滑动，疏散通道底板两端安装有安全栏杆。本发明实现了既不影响到桥梁伸缩缝处两端随着四季温度变化的伸缩问题，同时也能有效地解决电气或其他设备巡检人员的安全通行及疏散问题。本发明安全可靠、简单有效、性价比较高，在同类跨越江河的长桥或大型桥梁的建设和维护工作中具有较高的实用和推广价值。
