摘要
国内首台6MW风力发电机,于2011年8月18日在江苏射阳临港工业区开始安装首节塔筒。这台由华锐风电研发制造的SL6000HH100LZ62风力发电机,轮毂高度为100m,叶轮直径128m,采用了预埋地脚螺栓的基础结构形式。主要介绍了地脚螺栓安装精度控制、首节塔筒支撑调平、灌浆和地脚螺栓预紧力施加等关键过程在设计和施工方面所采取的措施。
Based on the extension project of Nanjing Jinling Hotel, the authors summarized the construction characteristics and analyzed the coordination transformation in construction surveying for super tall buildings. Specifically, the establishment of the aboveground and underground survey control systems were introduced in detail. The underground survey control system included the layout of the horizontal control network and elevation control network. The aboveground survey control system included the layout of ＋ 0. 000 control network, vertical transfer of the control network. The engineering practice shows that the established survey control system ensured the construction precision and allowed the site surveying to be conducted with flexibility and convenience.
