非开挖技术在市政给排水管道的应用及讨论非开挖技术在市政给排水管道的应用及讨论 摘要：城市市政给排水管道设计施工过程中常常会遇到穿越铁路、公路、河流、建筑物等障碍物，常常由于受到外部施工环境的影响，无法采纳开槽施工，因此非开挖技术便应运而生
采纳非开挖技术减少了土方开挖和回填的工作量，不必拆除地面障碍物及较浅的地下障碍物，同时所需施工空间亦较小，不会影响地面的交通及河道的正常通航，亦不受到季节及天气的影响
本文通过对非开挖技术在城市道路施工工程中的应用做出简要分析，希望能给市政给排水设计、施工中起到一定的参考作用

The use of trenchless technology reduces the earthwork excavation and backfilling work, do not have to remove obstacles on the ground and underground obstacles in shallow, at the same time need
