北京大兴国际机场航站楼核心区工程钢栈桥轨道运输系统设计与应用

Design and Application of Rail Transportation System for Steel Trestle in the Core Area of Beijing Daxing International Airport Terminal Building

为解决北京大兴国际机场航站楼核心区工程超大平面物料运输困难的问题,在建筑结构中设计并建造2条钢栈桥,在桥上铺设轨道,采用轨道运输车进行材料运输,有效解决超大平面结构中心部位塔式起重机相互需要喂料导致大量吊次不足等问题。

In order to solve the problem of transportation difficulty of super-large flat materials in Beijing new airport project, two steel trestle bridges are designed and built in the construction structure, then tracks are laid on the bridge and materials are transported by rail transport vehicles. This method can solve the practical problems of tower cranes in the center of super-large planar structure, such as insufficient hoisting due to mutual feeding.
