PST-60摇臂管棚钻机在软岩隧道中的应用与维护

摘要

Taking the tunnel exit of Taoshuping Tunnel along Lanzhou-Chongqing Railway as the engineering example,the paper introduces the application and maintenance of the PST-60 drilling machine exported from overseas to China,and indicates the technical points and difficulties in its process,and solves some construction difficulties in the soft rock construction in China effectively,so it accumulates some expereince for the construction with similar mechanical equipment in future.%以兰渝铁路桃树坪隧道出口为工程实例,介绍了国内首台引进PST-60钻机的应用与维护,以及该过程中的技术要点和难点,有效地解决了我国在软岩施工所遇到的施工难点,也为今后采用类似机械进行施工积累了经验。
