项目摘要

Water companies need enhanced information in two key areas to manage the current and strategic maintenance of sewers efficiently, which relates strongly to the operational and structural conditions and the rate of deterioration. As flooding caused by hydraulic overload can be tackled through capital investment, flooding other causes becomes increasingly significant as a failure of a service with heavy environmental, economical and social impacts. In many situations, it is more efficient to maintain the operational condition of a sewer regularly, rather then replace it in the case of structural collapse. Companies are now looking for new ways of reducing these incidents, however, the existing methods of sewer analysis and CCTV survey remain largely time-consuming and subjective.Recently, a series of acoustic experiments has been carried out by the investigators in a drained sewer pipe to identify the evolution of a small blockage. These initial results suggest that the acoustic signature of the sewer can be used to detect the location and extent of a minor change in the cross-section of a large-diameter pipe. Although, acoustic instruments have already been developed to determine variations of the cross-section of narrow pipes (e.g. musical instruments), there have been no systematic studies into the reconstruction of the cross-section profile of a realistic sewer pipe. The purpose of this project is to develop a novel practical and efficient acoustic technique to monitor the evolution of operation and structural conditions in live sewer networks.

水公司需要在两个关键领域中加强信息，以有效地管理下水道的当前和战略维护，这与操作和结构状况以及恶化速度密切相关。由于可以通过资本投资来解决由液压超负荷造成的洪水，因此由于遭受重大环境，经济和社会影响的服务失败，其他原因越来越重大。在许多情况下，定期保持下水道的操作条件更有效，而不是在结构崩溃的情况下取代下水道。公司现在正在寻找减少这些事件的新方法，但是，现有的下水道分析和CCTV调查的方法在很大程度上既耗时又主观。这些最初的结果表明，下水道的声学特征可用于检测大直径管的横截面的较小变化的位置和程度。尽管已经开发了声学仪器来确定狭窄管道（例如乐器）的横截面的变化，但尚无对逼真的下水道管道横截面轮廓重建的系统研究。该项目的目的是开发一种新颖的实用和高效的声学技术，以监测活下水道网络中的操作和结构条件的演变。
