缅甸耶涯水电站溢流面大跨度滑模施工技术

Slipform Construction Technology for the Spillway of Myanmar Yeywa Hydropower Station

耶涯水电站溢流面最大跨度27.72 m,采用滑模施工。由于跨度较大,轨道安装困难,为此,利用现有设备条件,摸索出一套适合该工程特点的一套滑模施工技术。施工时,滑模平均上升速度为30 cm/h,上升一次用时15 min,仅用3个月就全部完成滑模部位施工任务,且施工质量优良,成形面结构尺寸和误差均在标准要求之内。

The largest span of Yeywa Hydropower Station spillway is 27.72 m,and the construction of spillway use slipform.As the large span and difficult track installation,an appropriate slipform construction technology is studied.In the construction of spillway,the slipform lift speed is average of 30 cm per hour,per lift will cost 15 minutes.All construction is completed in 3 months,the quality is good and the size and shape errors of structure meet the requirements of standard.
