While the precast concrete pipe industry in Canada is more than a century old, it has suffered shrinking market share over the last few decades due to emerging competition from flexible pipe products. Technological breakthroughs are needed to invigorate this industry, which will benefit the Canadian economy. Meeting the end-user expectations, reducing cost, developing robust performance-based specifications and mitigating hydrogen sulfide corrosion problems are central to this strategy. This research project is conducted in partnership between a major reinforced concrete pipe (RCP) producer in Ontario and researchers from Western University. The team will first critically examine the state-of-the-art of RCP production and testing and propose needed changes to current RCP standards. Accordingly, more robust and accurate tests to quantify the mechanical and hydrostatic performance of RCP will be proposed. Cost-effective single elliptical steel cage reinforcement will be explored as an alternative to the traditional double (inner and outer) steel cage reinforcement. A new internally lined pipe coined "perfect pipe" will be investigated as a new generation of high-performance and durable RCP. Technological breakthroughs in concrete technology and nano-coatings will be deployed to mitigate bacteria induced corrosion problems in sewer RCP. Highly qualified personnel will be trained at both Con Cast Pipe, Guelph and Oakville, Ontario and the Structures Laboratory at Western University. The project will help the company develop competitive edge and generate additional revenue through gaining increased market share. It will also help the Canadian RCP industry at large strategically position itself as the North American leader in standard practice and new product development.

虽然加拿大的预制混凝土管道已有一个多世纪的历史了，但由于柔性管道产品的新兴竞争，在过去几十年中，它遭受了市场份额的缩小。需要技术突破来激发这一行业，这将使加拿大经济受益。满足最终用户期望，降低成本，开发出强大的基于性能的规格并减轻硫化氢腐蚀问题是该策略的核心。该研究项目是由安大略省的主要钢筋混凝土管（RCP）生产商与西部大学的研究人员之间的合作伙伴关系。该团队将首先批判性地检查RCP生产和测试的最新作品，并提出对当前RCP标准的所需更改。因此，将提出更健壮和准确的测试，以量化RCP的机械性和静液压性能。具有成本效益的单椭圆钢笼钢筋将被探索，以替代传统的双重（内部和外部）钢笼钢筋。新一代的高性能和耐用的RCP将研究一个新的内线管道创造的“完美管道”。混凝土技术和纳米涂料的技术突破将被部署以减轻细菌引起的下水道RCP腐蚀问题。高素质的人员将在康德管道，圭尔夫和奥克维尔，安大略省和西部大学的结构实验室接受培训。该项目将帮助公司发展竞争优势，并通过增加市场份额来获得额外的收入。它还将帮助加拿大皇家骑警在大量战略上将自己定位为标准实践和新产品开发领域的领导者。
