阿莱瓦水电站长缓斜井分级接力出渣技术

Classified-relay Slag Discharge Technology of Long and Gentle Inclined Slope of Allai Khwar Hydropower Station

针对阿莱瓦水电站引水隧洞斜井为特小断面长缓斜井的实际情况,介绍了特小断面长缓斜井的分级接力出渣技术和施工过程,较好地解决了工程的出渣问题,实现了斜井的按期贯通,取得了良好的经济效益和社会效益。

Inclined shaft of headrace tunnel of Allai Khwar Hydropower Station is long and gentle inclined shaftwith a small section, so this paper discusses classified-relay slag discharge technology and construction processsuitable for the long and gentle inclined shaft with a small section, which provides a better method to solve slagoutproblem, achieve run-through inclined shaft on schedule and bring great economic and social benefits.
