南京火车站站前广场环形高架平台桥加固工程中,采用体外预应力加固技术,仅用20d便可投入使用,并显著地提高了承载能力,技术合理,施工快捷方便,加固效果安全可靠,充分利用了钢绞线的高强特性。
In the reinforcement project of overhead ring platform bridge at station square of Nanjing Railway Station, external prestressing reinforcement technology is adopted, enabling the bridge to be used only after 20 days and improving bearing capacity of the bridge considerably. This construction method has many remarkable advantages, such as reasonable technology, convenient construction and safe and reliable reinforcement.
