Pipeline backfill reimagined to provide in-line corrosion protection

该项目旨在创新新型耐腐蚀管道回填材料、相关施工方法和数值技术，以最大限度地减少网络层面的腐蚀，同时考虑相邻管道之间的干扰影响。与仅提供机械支撑相比，本项目将通过阐明回填在管道腐蚀中的作用来设想回填用于在线腐蚀保护。预期的结果是非常有效和低成本的方法和工具，以提供在线保护，而不是昂贵的，并不总是可能的其他保护方法。该项目将通过解决地下空间严重拥挤的城市中心的腐蚀引起的管道故障，带来重大的经济效益。

This project aims to innovate new resistive pipeline backfill materials, associated construction methods and numerical techniques to minimise corrosion at network level, considering interference effects among adjacent pipelines. In contrast to only providing mechanical support, this project will envision backfill for in-line corrosion protection by elucidating its role in pipeline corrosion. The expected outcomes are very effective and low-cost approach and tools to provide in-line protection, in contrast to other protection methods that are expensive and not always possible. The project will bring significant economic benefits by addressing corrosion-induced pipe failures for urban centres, where underground space is heavily congested.
