广州地铁十四号线高架桥梁挡板创新设计

Innovative Design of Elevated Bridge Baffles for Guangzhou Metro Line 14

轨道交通地铁高架桥梁的挡板结构一般不设横坡,下雨天挡板顶的污水外溢,容易污染挡板的外侧;现有的挡板一般将电缆外挂在挡板内侧,容易造成外挂电缆暴晒,影响电缆的耐久性。针对上述问题,结合广州地铁十四号线高架区间桥梁设计,创新性地提出一种新型的高架桥梁的挡板结构,可避免污水污染竖向挡板的外表面,且作为电缆槽的基础,具有安全性高、设计合理且不会造成污染的特点。

Generally,there is no cross slope for the baffle structure of viaduct of rail transit,sewage overflowing from the top of the baffle in rainy days pollutes the outside of the baffle.The existing baffles usually hang the cables on the inside of the baffles,which is easy to cause the exposed cables and affect the durability of the cables.In view of the above problems,combined with the viaduct bridge design of Guangzhou metro line 14,a new type of baffle structure of viaduct is put forward innovatively.As the foundation of cable trough,the baffle has the characteristics of high safety,reasonable design and no pollution.
