江边水电站引水隧洞斜井段开挖施工

摘要

结合江边水电站引水斜井的实际情况，介绍了采用ALIMAK爬罐自下而上开挖导井，导井全部贯通后利用手风钻自上而下进行扩挖的斜井施工技术，重点介绍该引水斜井开挖施工工艺、方法及技术要点。%Combined with the actual conditions of the diversion inclined shaft of Jiangbian Hydropower Station ,an introduction was made on the inclined shaft construction technology. A pilot well was excavated from the bottom with ALIMAK climber before expanding excavation was conducted from top to bottom with hand pneumatic drill. Emphases of the introduction include construction technique,method and technical key points of diversion inclined shaft excavation.
