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。 关键词：非开挖技术；管道铺设；更换管道；施工技术 Abstract: water supply and drainage design of city municipal construction process often encounter through the railway, highway, river, obstacles such as buildings, often due to the impact of external construction environment, cannot use slotted construction, so the trenchless technology will emerge as the times require. 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 needed construction space is also small, will not affect the normal traffic and navigation channel of the ground, is not affected by seasons and weather. This paper makes a brief analysis on the application of Trenchless Technology in city road construction engineering, hoping to play a certain reference role for municipal drainage design, construction. Keywords: trenchless technology; pipe laying; replacing pipeline; construction technology 中图分类号：TL353+.2 文献标识码：A 文章编号：2095-2104（2025） 非开挖工程技术被广泛应用于穿越公路、铁路、建筑物、河流以及在闹市区、古迹保护区、农作物和环境保护区等不允许或不能开挖条件下市政管线的铺设、更修和修复。由于该技术的综合成本低、施工周期短、环境影响小、不影响交通、施工安全性好等优势日益受到人们的青睐，在市政给排水管线等...
