日本古河公司生产的ＣＪＭ１２００型砼喷射台车在天生桥电站施工时，正处于岩石严重破碎、风化、稳定性极差的恶劣环境，特别是在洞内施工遇到断层时，隧洞上方随时都有落石和大面积塌方的危险，使用该车取得了显著效果。本文拟简要介绍我们的使用经验。 该车的主要性能参数为
The CJM1200 squeezing jet car produced by the Furukawa Corporation of Japan is in a harsh environment where the rock is severely broken, weathered, and has extremely poor stability during the construction of the Tianshengqiao Power Station. Especially when there is a fault in the construction of the tunnel, the rock is always falling above the tunnel. With the danger of landslides and large areas, the use of this vehicle has achieved remarkable results. This article will briefly introduce our experience. The main performance parameters of the car are
