国家会议中心二期展览区地下钢结构施工技术

CHINA NATIONAL CONFERENCE CENTER PHASE Ⅱ CONSTRUCTION TECHNOLOGY OF UNDERGROUND STEEL STRUCTURE IN EXHIBITION AREA

国家会议中心二期展览区地下钢结构施工场区大、构件重量重,现场起重机距基坑较远,致使钢构件水平运输困难。因此,在构件卸车、移动机构放置、超重构件存放、运输区域楼板加固等方面采取措施,控制了工期,降低了施工成本。

The underground steel structure construction site of exhibition area of China National Conference Center Phase Ⅱ is large and the components are heavy.The crane on site is far away from the foundation pit,making it difficult to transport the steel components horizontally.Therefore,measures have been taken in the aspects of component unloading,mobile mechanism placement,overweight component storage,and floor reinforcement in the transportation area,to control the construction period and reduce the construction cost.
