液压滑模技术在溪洛渡水电站高线砼生产系统骨料竖井施工中的应用

Application of Hydraulic Sliding Mode Technology in Altitude Concrete Production System Aggregate Shaft Construction

溪洛渡水电站工程高线砼系统布置在大坝右坝肩下游,其骨料储运系统布置在下游EL.705平台地面以下山体中,共布置有粗骨料竖井4个、细骨料竖井2个,竖井深度55～77m。该项目成功采用液压滑模技术进行大高差、薄壁井筒骨料竖井混凝土衬砌施工,具有施工速度快、质量高、成本低、安全有保障的特点。

Altitude concrete system of Xiluodu hydropower station project was arranged in the downstream of right dame abutment,and its aggregate storage and transportation system was arranged in mountain body under the dowstream EL. 705 platform. There were 4 coarse aggregate shafts and 2 fine aggregate shafts with depth of 55-77 m. This project successfully adopted hydraulic sliding model technology to carry out concrete lining construction of the large elevation difference thin-wall aggregate shafts with characteristics of rapid construction, high quality, low cost, safety.
