有计算机辅助的隧道凿岩台车已经在一些遂道工程中进行了试用,但效果不一。霍达兰Statens vegvesen的公路隧道局在1990年完成了用新一代计算机控制的凿岩台车开挖的第一座公路隧道。现在已经开挖了大约4000m的隧道,获得的经验令人非常满意。看来这种凿岩台车还存在着潜力,完全可以较低的价格供应更好的产品,主要是降低过大的重量并提高其生产效率。在购买之前应对这种计算机辅助的台车的工作能力进行全面评估,这种设备是先进的,但也意味着在维修、训练及后援工作上要有较多的支出。
Computer-aided tunnel drilling rigs have been tested in some tunneling projects, but with mixed results. The Highway Tunnel Authority at Statens Vegvesen, Hordaland completed the first road tunnel excavated with a new generation of computer-controlled rock drilling rigs in 1990. We have now excavated about 4000m of tunnels and the experience gained is very satisfactory. It appears that this rock drilling rig has the potential to supply a better product at a lower price, primarily by reducing excessive weight and increasing its production efficiency. A thorough assessment of the capabilities of this computer-aided trolley should be made prior to purchase. The equipment is advanced, but it also means more expenditure on repairs, training and support.
