Recently, the foundation treatment project for CATL's lithium mine in Fengxin, Yichun, Jiangxi, constructed by Jiangxi Jiye Technology Group Co., Ltd., welcomed a delegation of experts from China's geotechnical industry. Renowned domestic experts and scholars, including Gong Xiaonan, Professor and Academician of Zhejiang University; Gao Wensheng, Director of the Foundation Engineering Institute of China Academy of Building Research; Zhu Chunming, Researcher of China Academy of Building Research; Liu Xiaomin, Consultant Chief Engineer of Shenzhen Investigation & Research Institute; Ye Guanbao, Professor of Tongji University; and Shao Zhongxin, Chief Engineer of Hefei University of Technology Foundation Engineering Company, accompanied by Liu Xiangang (Professor-level Senior Engineer), Chairman of Jiye Technology, came to this mountainous area to find out the truth behind this major question.

After driving along winding and steep mountain roads, the vehicles stopped at a temporary parking area built for the project. Guided by on-site staff, the experts arrived at the inspection site, where they were greeted by operating "track-following column hammer stone-breaking and compaction piles" equipment. Upon seeing this equipment, half of the experts' doubts were immediately resolved.

By splicing column hammers, the equipment forms a hammer body up to 20m high. The effective treatment depth can be seen at a glance based on the hammer height and the depth driven into the soil. The effective treatment depth can reach ≥20m, equal to the hammer height. The hammer has the ability to break stones, compact soil, and penetrate cavities. It completely solves the problems of difficult compaction and penetration in high fill slopes and hidden boulders (floating stones) that traditional processes face.

The project under construction is Phase III; Phases I and II have been completed and their superstructures have been topped out (see photo above). The total fill thickness of the project reaches 40–70m, constructed in three or four layers, using high-strength composite foundation treatment technologies such as the track-following column hammer stone-breaking and compaction pile plus combined hammer method invented by Jiye Technology. Recalculation of the completed works shows that this technology saves 32% in construction cost for the owner, reduces carbon emissions by 50%, and shortens the construction period by more than 60%. It has been highly praised by the owner, who even granted an additional bonus.

Wang Tao, Member of the Party Committee of Jianyan Foundation Engineering Company and Director of the Design and Research Development Center; Li Jianmin, Deputy Director of the Survey and Mapping Institute and Director of the Existing Building Reinforcement and Renovation Research Center; Li Xiangyu, Deputy Director of the Design and Research Development Center and Director of the Underground Space Research Center; Sun Xunhai, General Manager of the Fourth Branch and Director of the Foundation Treatment and Composite Foundation Research Center; and Zheng Wenhua, Director of the Comprehensive Management Department of the Design and Research Development Center, visited and inspected the site.

Chairman Liu introduced: This innovative technology has applied for and obtained multiple national patents. After more than three years of base tests, site practices, and multiple inspections, it was officially put into engineering application.

During the visit, the experts once again praised Jiye Technology's innovative spirit and offered suggestions for further optimization on site. They believe that with further optimization in deep inspection, the market prospect of this technology will be even broader.

Subsequently, the experts visited Jiye Technology's "Geotechnical Engineering Process Research Base" at Huling Manor in Changnan. After touring the fruit and vegetable manor, they further exchanged and discussed in depth the research direction of geotechnical processes, enterprise development, and the transformation of scientific research achievements.

Afterwards, Chairman Liu Xiangang expressed his great gratitude for the suggestions and guidance from Academician Gong and other experts and leaders!
