天湖水电站压力水道竖井和斜井施工

Construction of the Penstock's Rising Shaft and Inclined Shaft of the Tianhu Hydropower Station

天湖水电站407m深无衬砌竖井和384m长无衬砌斜井采用激光定向、光面爆破新技术施工,竖井风水管路、风筒用金属锲形锚杆悬挂在井壁上,节省了8台稳车的安装。斜井用4级电扒接力出碴,简化了施工工艺,缩短了施工工期,取得了较好的经济效益。

In construction of both, the 407m deep non—liner rising shaft and the inclined one, 384m long, we adopt a series of new techniques, such as: laser direction finding and smooth blasting. The wind—water pipe and blower of rasing shaft were hung on the shaft with metal carve type of anchor, which saved the installation of eight stable cars. Inclined shaft is servoed and mucked out with the four level electric taker, which simplified the construction technique shortened the construction time, and obtained better economic benefit.
