导向钻进管道敷设工艺的质量技术控制要点

摘 要:随着近年来拖拉管（导向钻进）管道敷设工艺的逐渐广泛应用，这一非开挖管道工艺能最大限度地降低地下管线施工时对地面交通与周边环境的影响。但该工艺的新颖性也决定了其在施工过程中质量技术控制标准参差不齐，本文主要从拖拉管（导向钻进）管道敷设工艺的材料选用及施工流程中工序的施工方法进行剖析与探讨，归纳出该工艺的部分质量技术控制要点。

abstract: along with the recent years towable tube ( directional drilling pipe laying technology ) gradually extensive application, the trenchless pipeline technique can minimize the underground pipeline construction on the traffic and environment effects. but the technology novelty also determines the construction process in quality control of uneven technology standard, this article mainly from the hauling pipe (directional drilling pipe laying technology) material selection and construction process construction method for analysis and discussion, the author summarizes the technology part of the key points of quality control.
