奥地利沃拉水工隧洞直径3.5米,长6.7公里,穿过坚硬少断裂的岩石。施工时,除起始一段(长135米,为断裂岩石)用钻爆法开挖加喷锚支护外,其余用阿特拉斯隧洞掘进机从一个工作面掘进,不加支护。掘进机的主要特性是:通过的隧洞断面的直径为3.5米,电动机的总功率为596.4千瓦(4 x 149.1千瓦);对工作面的推力为635吨;刀具数为26,直径39.4厘米;机身长11.6米,机身重150吨。整个隧洞的设计岩石开挖量为70,000米~3(实方)。开挖出的石碴(当掘进机最大生产能力为60米~3/小时时)通过输送机系统进入10～12台斗车中,再用蓄电电气机车送到洞外。隧洞掘进的平均速度一昼夜为32延米,一
Austria Willa hydraulic tunnel diameter of 3.5 meters, 6.7 kilometers long, less hard to break through the rocks. During the construction, except for the initial section (length of 135 meters, for the fracture of rock) with the drilling and blasting excavation plus spray anchor support, the rest of the Atlas tunnel boring machine heading from a working face, without support. The main features of the roadheader are: the diameter of the tunnel section passing through the tunnel is 3.5 meters, the total power of the motor is 596.4 kilowatts (4 x 149.1 kilowatts); the thrust of the working face is 635 tons; the number of knives is 26 and the diameter is 39.4 centimeters; 11.6 meters long, weighing 150 tons. The design of the entire tunnel rock excavation volume of 70,000 m ~ 3 (real). Excavation of the ballast (when the maximum boring machine production capacity of 60 m ~ 3 / hour) through the conveyor system into the 10-12 bucket car, and then use storage electric locomotives sent to the hole. The average speed of tunneling day and night for 32 meters, one
