根据结构特点,制定施工方案,主 站房部分采用逆序法施工,先进行上部屋盖桁架施工,采用散件运输、地面拼装、整体吊装、高空组装的施工方法; 后进行下部框架层施工,采用地面拼装、高空组对的施工方法。
雨篷采用高空散装的方法吊装。
重点介绍了钢构 件制作加工、现场拼装及安装等施工工艺。

The main body ofthis project dopts steel struturewhose ponents arediffcult tobefabricated an installed especially for main station building,which has characteristics of large span, large cantilever, large section and heavy body. It is difficult for construction. According to the structural characteristics, inverted sequence construction method is applied for main station building. For upper roof truss, the construction method of partial transportation, assembling on ground, integral lifing and assembly at high altitude is applied. For lower frame, the construction method of assembling on ground and assembling at high altitude is used. And for canopy, assembling at high altitude is adopted. The fabrication and processing of steel ponents, assembling on site and installtion are introduced in detail.
