某体育馆网架逐步外扩同步液压整体顶升施工技术

Construction Technology of Synchronous Hydraulic Jacking

针对兰州市某体育馆项目的屋盖结构形式,采用逐步外扩同步液压整体顶升施工技术,详细阐述了其工艺原理,并对其工艺流程和控制要点进行概述,实施效果表明,这一技术在大跨度下部结构呈“碗状”等复杂环境的场馆的屋盖系统实施的可行性,给其他类似工程提供借鉴及思路。

In view of the roof structure of Lanzhou city gymnasium project form,using gradually expanding synchronous hydraulic overall jacking construction technology,elaborated the process principle,and outline the process and control points,the implementation effect shows that the technology in large span substructure is"bowl"and other complex environment of the feasibility of the roof system,for other similar engineering and ideas.
