以江苏某城市地下排水管道开挖法修复工程为例,介绍了工程施工过程及存在的各种问题,以图表的形式对开挖法与非开挖法修复城市地下排水管道进行了技术经济分析,认为正确采用非开挖修复管道技术可以有效减小对地面建筑物及交通的影响,最大化保护人民生活环境,延长管道使用寿命,降低环境污染,减少因管道问题所导致的城市管理问题.城市地下管道非开挖修复技术施工速度快,施工费用低,经济效益、环境效益明显,具有较高的推广应用价值.
英文摘要：
Taking one repairing project of underground drainage pipeline with excavation method in some city of Jiangsu province as an example, this paper introduces the work progress and problems, carries out technical economy analysis on repairing urban underground drainage pipeline with excavation and non-excavation method by using charts. It concludes that through using non-excavation method correctly, we can decrease the impact on surface buildings and traffic efficiently, furthest protect the environment, increase the service life, reduce environmental pollution and decrease city management problems caused by pipelines. Non-excavation technique has the advantages of rapid construction speed, low cost and obvious economic and environment benefits, which conclude high popularization and application values.
