浅谈福建仙游抽水蓄能电站斜井滑模混凝土施工

摘要

福建仙游抽水蓄能电站单条引水隧洞总长约1148m （其中上、下斜井长分别为387.6m 和311.1m），高差为490.4m，洞内衬砌内径为6.5～3.8m，上、下斜井倾角均为50°，采用连续拉伸式液压千斤顶-钢绞线滑模系统（简称 LSD 斜井滑模系统）施工。本文着重对滑模施工方案、配合比等进行简要介绍。%Single water diversion tunnel of Fujian Xianyou Pumped Storage Power Station has total length of about 1148 m (wherein upper and lower inclined shafts are respectively 387.6 m and 311.1m long).The height difference is 490.4m. Inner diameter of lining in the tunnel is 6.5 ~3.8m.The inclined angles of upper and lower inclined shafts are all 50°. Continuous drawing type hydraulic jack -steel strand slipform system (hereinafter referred to as LSD inclined shaft slipform system)is adopted for construction.In the paper,slipform construction plan,mixture ratio,etc.are briefly introduced.
