饮用水管道大多埋在地下，并在那里停留了几十年，需要适当的维护，以防止故障。在各种材料中，聚氯乙烯（PVC）由于其具有高耐久性、耐腐蚀性、低价格和易于安装等优点而得到广泛应用。据我们所知，这是第一篇回顾连续监测PVC饮用水管结构健康的检查方法的文章。为了了解哪些属性需要检查，我们首先调查了影响PVC管道和接头失效的属性。然后，我们回顾了已经应用或可以检查这些影响属性的方法。我们将前景分为五组：1）声波; 2）光纤传感; 3）液压监测; 4）多个离散传感器; 5）其他在线方法。最后，我们讨论了实施这些方法到PVC水管的连续监测系统的早期故障预警的可能性和挑战。结果，其中包括主动声波，光纤传感，液压振动，和多个离散传感器的方法，可以帮助未来的研究人员选择合适的方法来开发连续监测系统的PVC水管。
The drinking water mains, mostly buried underground and stay there for decades, require proper maintenance to prevent failures. Among different kinds of material, polyvinyl chloride (PVC) has been widely used due to positive features, such as high durability, corrosion resistance, low price, and easy installation. To the best of our knowledge, this is the first article that reviews the inspection methods toward continuously monitoring the structural health of PVC drinking water mains. To understand which properties need inspecting, we first investigated the attributes that influence PVC pipe and joint failures. Then, we reviewed the methods that have already been applied or can inspect these influencing attributes. We categorized the prospects into five groups: 1) sound wave; 2) fiber optic sensing; 3) hydraulic monitoring; 4) multiple discrete sensors; and 5) other inline methods. Finally, we discussed the possibility and challenges in implementing these methods into a continuous monitoring system of PVC water mains for early failure warning. The result, which includes active sound wave, fiber optic sensing, hydraulic vibration, and multiple discrete sensors methods, can help future researchers select the appropriate methods to develop the continuous monitoring system for the PVC water mains.
