大坡度小断面输水隧洞主支洞交叉段出渣及喷锚系统的研究与应用

Research and Application of Slag Discharge and Shotcrete Anchor System in Crossing Section of Main Branch Tunnel of Large Slope and Small Section Water Conveyance Tunnel

针对大坡度小断面输水隧洞主支洞交叉段出渣及喷锚系统研究,并在工程实践中得以应用,证明该系统能够保证工程安全,加快出渣速度及喷锚的进度,提高工程效率,取得良好的经济和社会效益,可推广使用。

This paper studies the slag discharge and and shotcrete anchor system at the intersection of the main adit of the large slope and small section water conveyance tunnel,and applies it in the engineering practice.The results show that the system can ensure the engineering safety,accelerate the slag discharge speed and the progress of shotcrete anchor,improve the engineering efficiency,and obtain good economic and social benefits,and is suitable to be popularized.
