Pipelines are the primary means of transporting energy or resources, such as oil, natural gas, or water. Nowadays, with the increasing demand for resources, the construction of pipelines is also increasing. Under the context of promoting green production, the open-cut method has been unable to meet the requirements of environmental protection. Therefore, trenchless technology has become an alternative to pipeline construction, which has the characteristics of fast construction speed and low carbon footprint. This paper briefly introduces a variety of typical trenchless installation and renewal methods. Based on the relevant theory of carbon footprint calculation during construction, the energy consumption and carbon footprint from the open-cut method and the trenchless construction methods under the same conditions are compared. Moreover, the sensitivity of different construction methods to different factors is analyzed. The main conclusions are drawn: (1) In most cases, the cured-in-place pipe method has less energy consumption and carbon footprint than other pipeline repair methods and is less affected by various design factors. (2) Various trenchless technologies have reduced construction energy consumption and carbon footprint to varying degrees relative to the open-cut method. (3) When the construction length is short or the depth is very shallow, the energy consumption and carbon footprint of the trenchless method may be higher than the open-cut method.

非开挖技术如何使管道建设更环保?全面的碳足迹和能耗分析

管道是运输能源或资源(例如石油,天然气或水)的主要手段。如今,随着对资源需求的增加,管道的建设也在增加。在促进绿色生产的背景下,开放式方法已不能满足环保要求。因此,非开挖技术已经成为管道建设的替代方案,具有建设速度快,碳足迹低的特点。本文简要介绍了各种典型的非开挖安装和更新方法。基于施工过程中碳足迹计算的相关理论,比较了相同条件下明挖法和非开挖法的能耗和碳足迹。此外,分析了不同施工方法对不同因素的敏感性。得出以下主要结论:(1)在大多数情况下,现场固化管道方法比其他管道修复方法具有更低的能耗和碳足迹,并且受各种设计因素的影响较小。(2)相对于明挖法,各种非开挖技术已不同程度地减少了建筑能耗和碳足迹。(3)当施工长度短或深度很浅时,非开挖法的能耗和碳足迹可能会比明挖法高。与其他管道维修方法相比,现场固化管道方法的能耗和碳足迹更少,并且受各种设计因素的影响也较小。(2)相对于明挖法,各种非开挖技术已不同程度地减少了建筑能耗和碳足迹。(3)当施工长度短或深度很浅时,非开挖法的能耗和碳足迹可能会比明挖法高。与其他管道维修方法相比,现场固化管道方法的能耗和碳足迹更少,并且受各种设计因素的影响也较小。(2)相对于明挖法,各种非开挖技术已不同程度地减少了建筑能耗和碳足迹。(3)当施工长度短或深度很浅时,非开挖法的能耗和碳足迹可能会比明挖法高。
