近几年来,用Alimak天井爬罐掘进了几条长天井。文中介绍的这条长867米、倾角45°、断面6米~2的天井是挪威麦尔水电工程的主供水道,于1988年6月掘通。35周完成该井的掘进工作,每周工作12班,平均每周进尺25米,即每班进尺为2.06米。该水电工程的压力隧道顶板标高为304米,于此置Alimak爬罐,按45°倾角向上掘进穿过797米标高的3000米水平隧道,再向上掘进175米通达地表,全长867米。所用爬罐是STH-5DD型,柴油-液压驱动。此机
In recent years, several long-length wells have been excavated using the Alimak patio. This article describes the 867 meters long, 45 ° dip angle, section 6 m ~ 2 patio is the main waterway of the Maier hydropower project in Norway, in June 1988 to break through. 35 weeks to complete the tunneling work well, work 12 weekly classes, the average weekly footage of 25 meters, that is, each class footage into 2.06 meters. The hydropower station’s pressure tunnel roof elevation of 304 meters, in which the Alimak climbing cans, up 45 ° dip through the 797-meter-high 3000 m horizontal tunnel, and then heading up 175 meters to reach the Earth’s surface, a total length of 867 meters. Climbing tank used is STH-5DD type, diesel-hydraulic drive. This machine
