Recently, the 7th Technological Innovation Conference of the Engineering Construction Industry, hosted by the China Construction Enterprise Management Association, was held in Changzhou. The Comprehensive Utilization Technology of Earthwork Resources in Canal Engineering, developed under the leadership of Professor Xiao Jianzhuang from Guangxi University in collaboration with Pinglu Canal Group Co., Ltd., Guangxi University, China Communications Construction Group Co., Ltd., and Guangxi Transportation Design Group Co., Ltd., was selected as one of the National Top Ten New Technologies in Engineering Construction for 2025.

As a backbone project of China's Western Land-Sea Corridor and a landmark initiative for accelerating the development of a transportation powerhouse, the Pinglu Canal project generated approximately 315 million cubic meters of spoil during construction, facing challenges such as tight schedules, limited workspaces, and difficulties in earthwork transportation and allocation. The research team conducted industry-academia-research collaboration on comprehensive utilization technology for canal engineering earthwork resources. They focused on the classification and categorization of engineering spoil, inventing rapid identification technology for spoil properties and proposing transparent excavation and dredging visualization methods for waterways. To address green engineering challenges, they developed multi-path resource utilization technologies and equipment for engineering spoil, and invented intelligent regulation methods for multi-source solid waste-based recycled concrete. Regarding safety, efficiency, and risk early warning requirements, they established an intelligent management system for earthwork resource utilization and developed a decision-making platform based on the DeepSeek large model for canal earthwork, achieving risk assessment and advanced early warning for over 130 spoil storage sites along the canal. These innovative technological achievements have not only resolved the challenges of resource disposal and low-carbon utilization of massive engineering spoil from the Pinglu Canal but have also provided a new paradigm for major infrastructure engineering projects domestically and internationally.

This new technological achievement not only marks a breakthrough in engineering construction technology by our university but also exemplifies our commitment to deep industry-academia-research integration, translating research into tangible impacts on national projects like the Pinglu Canal. It reflects both the industry’s high recognition of the university’s research capabilities and our dedication to the principle of "being action-oriented and innovation-driven." As a core partner of the Guangxi Modern Canal Laboratory, Guangxi University will continue to prioritize major engineering needs, deepen collaborative innovation across industry, academia, and research, and contribute further expertise to the construction of the Pinglu Canal and the development of the Western Land-Sea Corridor.
