Wet Shotcrete Mechanical Arm Applied in Tunnel

Yang Kai;Deng Zonggang;China Railway 12th Bureau Group Co. Ltd.;  
This article combines with the application of the concrete wet shotcrete mechanical arm at the exit of the tunnel of Qinling Tianhua Mountain,Xi'an-Chengdu Passenger Dedicated Line,stating from the model selection,construction technique of wet shotcrete mechanical arm and point of quality control and so on. By analyzing and contrasting with the traditional technique of dry shotcrete from the quality,efficiency,cost,resilient rate,working environment,concrete mix proportion,volume of accelerating agent,etc.,it shows the advantage of wet shotcrete in hard rock with the method of full section excavation. To some extent,it has the value to extend the use of wet shotcrete mechanical arm.
