摘    要:针对非开挖施工中清渣困难的问题,首次将反循环清渣工艺引入非开挖施工中。从理论上计算了传统非开挖和反循环的清渣泵量,计算结果表明,反循环清渣所需泵量远远低于传统的非开挖泵量,从而提出将反循环工艺应用于非开挖清渣施工中。实际应用效果表明,反循环清渣工艺可大大提高非开挖施工中的清渣效果。

关 键 词:非开挖  反循环  清渣  泥浆泵量

Abstract:Aimed at the difficult problems about removing drill dregs in trenchiess laying, the reverse circulation technology, for the first time, is applied in the trenehless techniques. In the paper, the power of mud pump for removing the drill dregs in traditional trenehless 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.
Keywords:trenehless laying  reverse circulation technique  removing drill dregs  the power of mud pump
