摘要
"反井法"施工是先钻导向孔,然后自下而上开凿用于溜碴的导井,再用传统钻爆法自上而下扩挖成井的方法。运宝高速公路中条山隧道2号竖井运用"反井法"施工,取得了良好的效果,保证了工程质量、工期,且节约了费用,为我们以后特长隧道竖井设计和施工提供了参考。
This paper introduced the application of 'back well drill method'in Zhongtiaoshan Tunnel of Yunbao Highway, which achieved the good results and ensured the engineering quality and period, saved the cost.It also provided the reference for design and construction of extra-long tunnel shaft in the future.
