项目摘要
CBET 1336616Marc EdwardsVirginia TechAs the nation's aging potable water pipeline systems fall deeper into disrepair, and costs of traditional pipe replacement increasingly dwarf societal abilities to pay for upgrades, innovative approaches to sustain pipeline assets are urgently needed. We have discovered that our existing pipe materials (i.e., iron, cement, and copper) have a remarkable ability for autogenous leak self-repair that has heretofore been unexploited, providing possible approaches to pipeline restoration at costs orders of magnitude lower than conventional alternatives. Our ultimate objective is to rationally engineer the chemistry of drinking water to seal existing leak-holes formed in existing materials via clogging with waterborne and/or water-formed particles. A laboratory phase of research establishes fundamental mechanisms of (1) leak clogging by model particulates commonly found in water distribution systems, (2) "smart" precipitation of crystalline CaCO3(s) in leak-holes, and (3) metallic corrosion as a pathway for repairing leaks. Parallel large-scale application of the approach to extend the lifetime of New York City's iconic Delaware Aqueduct will provide valuable data and insights to both leak clogging and "smart precipitation."This research is the first to demonstrate that existing leaks in aged pipelines do not inevitably grow to failure, but can actually provide a pathway to self-repair via water chemistry. Such low cost, environmentally friendly solutions to one of the most urgent infrastructure problems facing the developed world, has the potential to save tens of billions of dollars per year in reduced damages, water loss, and capital expenditures. Repair of leaks enhances water conservation/sustainability and protects public health by reducing the likelihood of contaminant influx into pipelines. After more than a century of research aimed at minimizing problems with corrosion, scaling and particle formation in potable water systems at every opportunity, the possibility that these processes can be beneficially exploited to repair existing pipelines would represent a true paradigm shift. The basic science and concepts also have direct linkages to economically sustaining other decaying infrastructure assets including sewage pipelines and concrete structures.
随着美国日益老化的饮用水管道系统年久失修,传统管道更换的成本越来越使社会支付升级费用的能力相形见绌,迫切需要创新的方法来维持管道资产。我们已经发现,我们现有的管道材料(即,铁、水泥和铜)具有迄今为止尚未开发的自生泄漏自修复的显著能力,从而以比常规替代方案低几个数量级的成本提供了管道修复的可能方法。我们的最终目标是合理地设计饮用水的化学性质,以密封现有材料中通过水性和/或水形成的颗粒堵塞而形成的现有泄漏孔。 实验室阶段的研究建立了以下基本机制:(1)配水系统中常见的模型颗粒堵塞泄漏,(2)泄漏孔中结晶CaCO 3的“智能”沉淀,以及(3)金属腐蚀作为修复泄漏的途径。 并行大规模应用的方法,以延长纽约市的标志性特拉华州渡槽的寿命将提供有价值的数据和见解,泄漏堵塞和“智能降水。“这项研究首次证明,老化管道中现有的泄漏不会不可避免地发展到失效,但实际上可以通过水化学提供一种自我修复的途径。 这种低成本、环境友好的解决方案是发达国家面临的最紧迫的基础设施问题之一,每年有可能在减少损害、水损失和资本支出方面节省数百亿美元。修复泄漏可提高水资源保护/可持续性,并通过减少污染物流入管道的可能性来保护公众健康。经过世纪多的研究,旨在尽量减少与饮用水系统中的腐蚀,结垢和颗粒形成的问题,在每一个机会,这些过程可以有益地利用来修复现有的管道的可能性将代表一个真正的范式转变。 基础科学和概念也与经济上维持其他老化的基础设施资产有直接联系,包括污水管道和混凝土结构。
