引水隧洞全断面通用钢模台车设计及施工技术

Design and construction technology of full face steel mould trolley for diversion tunnel

云南乌弄龙水电站引水隧洞衬砌采用了全断面钢模台车,在施工过程中,通过调节模板、铰连接和模板支座的置换,实现同一台车在平洞段及转弯洞段的连续施工。本文对全断面通用钢模台车设计及施工技术进行了分析,探讨了全断面通用钢模台车的关键技术。

Full face steel mould trolley was adopted for the diversion tunnel lining of Wunonglong Hydropower Proj⁃ect in Yunnan Province.The horizontal and turning tunnel sections were constructed continuously with the same trolley by adjustment of mould,hinged connection and replacement of mould support.The author analyzed the de⁃sign and construction technology of full face steel mould trolley,and discussed the key technology.
