针对非开挖铺设中清除钻渣的难题，首次将反循环技术应用于非开挖技术中。对传统非开挖技术和反循环技术中泥浆泵清除钻渣的功率进行了理论计算，结果表明前者大于后者。反循环切割清理技术在非开挖施工实践中的应用，大大提高了钻孔中的出渣率。
Aimed at the difficult problems about removing drill dregs in trenchless laying,the reverse circulation technology,for the first time,is applied in the trenchless techniques.In the paper,the power of mud pump for removing the drill dregs in traditional trenchless technique and in reverse circulation technique have been theoretical calculated,the result show that the former is more than the latter.The reverse circulation cutting cleaning techniques applied in the practice trenchless laying have greatly improved the rate of removing dregs in bore-hole.
