摘要
引洮供水二期工程总干渠33#及34#隧洞属于典型小断面输水隧洞,为达到钻爆法高效、安全及优质施工目的,针对隧洞工程技术特性,在对开挖掘进及支护衬砌全面分析的基础上,提出了相应施工技术与质量控制措施要点,工程施工实践取得优异成效,可为类似引输水隧洞工程参考借鉴。
The 33# and 34# tunnels of the main canal of Tao River Diversion Water Supply Phase II Project are typical small-section water conveyance tunnels. In order to achieve the purpose of high efficiency, safety and high quality construction of the drilling and blasting method, the technical characteristics of the tunnel engineering are to be excavated and supported. On the basis of comprehensive analysis, the corresponding construction technology and quality control measures are put forward, and the engineering construction practice has achieved excellent results, which can be used as reference for similar water conveyance tunnel projects.
