采用层次分析法对排水管道非开挖修复技术优选研究

Analytic hierarchy process to select the optimal technique for trenchless sewer pipeline rehabilitation engineering

针对破损排水管道在选择非开挖修复技术时存在的多因素、多层次、多目标问题,以广州市中心城区地下排水管道非开挖修复为例,采用层次分析法,对DN300-800的排水管道,从施工条件、费用、效益等方面,分析比较了螺旋缠绕法、原位固化法和穿插法3种非开挖修复技术的适用性。结果表明,原位固化法比较适用于广州中心城区DN300-800排水管道的非开挖修复。

According to the typical dejects of sewer pipeline in the central urban area of Guangzhou City and multi-factor, multi-level and multi-target characteristics of trenchless rehabilitation technology decision, analytic hierarchy process （AHP） is applied to compare the applicability of spiral wound lining method, cured-in-place pipe method and slip lining method, by analyzing their construction condition, cost, benefit etc.. The diameters of pipes range from 300 to 800 mm. Results show that cured-in-place pipe is preferable for this type of sewer pipeline rehabilitation.
