Abstract: Exploring the basic technical challenges faced by low-carbon construction in canal engineering and proposing strategies for technological development contribute to improving the theory and technology of low-carbon canal engineering construction in China, providing a reference for future international and domestic canal engineering projects. This paper briefly reviews the construction of ancient and modern canal projects in China, clarifying the necessity of low-carbon canal engineering construction from the perspectives of commonalities in low-carbon development of major infrastructure and the uniqueness of low-carbon canal engineering construction. The difficulty in canal engineering construction in the new era lies in enhancing low-carbon practices while ensuring reliability. Therefore, the basic technical issues of low-carbon canal engineering construction focus on low-carbon assurance. Based on the low-carbon technological breakthroughs in the Pinglu Canal, a century-scale project, this paper highlights fundamental technical issues such as efficient use of canal construction materials, efficient utilization of new and old canal components, multidimensional solid waste recycling in canals, canal durability assurance and biodiversity conservation along the canal, and low-energy consumption in canal construction, operation, and maintenance. A 5R low-carbon construction technology framework consisting of reduction, reuse, recycling, resilience, and renewable energy is proposed to precisely address the basic technical issues of low-carbon canal engineering construction. Low-carbon canal engineering construction is in its infancy, and it is recommended that the academic and engineering communities continue to pay attention to, ponder over, and research this emerging field.

Keywords: canal engineering, low-carbon construction, reduction, reuse, recycling, resilience, renewable energy
