To promote innovation and application of new waterproofing technologies in water conservancy engineering construction in Xuzhou, and to build an industry platform for technical exchange and cooperation, a waterproofing construction technology exchange meeting, jointly hosted by Xuzhou Jing'an Heavy Industry, the Infrastructure Division of Xuzhou Water Affairs Bureau, and Xuzhou Hydraulic Engineering Society, was successfully held on September 9, 2025. Li Jingfeng, General Manager of Xuzhou Jing'an Heavy Industry Machinery Manufacturing Co., Ltd., delivered a special technical report on behalf of the company, sharing the enterprise's core technical achievements in the field of waterproofing construction, which sparked enthusiastic responses from attending guests.

　　This exchange meeting focused on key technologies for waterproofing construction in water conservancy engineering, aiming to solve waterproofing construction challenges and improve the quality and safety level of water conservancy engineering through technical sharing and experience exchange. At the meeting, General Manager Li Jingfeng delivered a report themed "Application Practice of TRD Chain Cutter Wall-Forming Technology," elaborating in detail on the technical principles, construction processes, and practical application cases of this technology. According to the introduction, the core equipment of the TRD chain cutter wall-forming technology can insert the cutter box to a depth of 40-70 meters underground; through the continuous agitation of cement-soil slurry by the chain cutters on the cutter box, combined with the equipment's forward advancement, a continuous and solidunderground waterproofing wallis ultimately constructed. This technology can be widely applied in scenarios such as reservoir dams, river and lake embankments, and bridge foundation waterproofing, building a solid underground "waterproofing barrier" for water conservancy engineering and effectively solving problems of traditional waterproofing technologies such as insufficient depth and poor sealing performance.

　　Subsequently, General Manager Li Jingfeng also provided a systematic explanation of the "CSM method and method machine," and through playing live-action videos of embankment waterproofing construction, visually demonstrated the application effects of the two technologies in actual engineering, giving participants a clearer understanding of equipment operating efficiency and waterproofing quality.

　　During the exchange and discussion session, participants engaged in in-depth discussions around core topics such as "waterproofing method optimization, construction quality control, waterproofing effect testing,construction cost control" and others. Twenty-seven representatives from units including the Infrastructure Division of Xuzhou Water Affairs Bureau, Xuzhou Hydraulic Engineering Construction Management Center, Xuzhou Water Conservancy Architectural Design Research Institute Co., Ltd., the Water Conservancy Engineering Construction Management Center of the Yishusi Water Conservancy Administration Bureau of the Huai River Commission, and Huaihe Engineering Group Co., Ltd., combined their own engineering practice experience to raise targeted questions about the technologies shared by Jing'an Heavy Industry, and offered valuable suggestions on process improvement and adaptability optimization. The on-site academic atmosphere was strong, with frequent exchanges of viewpoints, resulting in multiple exchange outcomes of practical value.

　　The convening of this exchange meeting not only built a bridge for technology sharing in Xuzhou's water conservancy industry, but also promoted the implementation and application of cutting-edge waterproofing construction technologies. Through technical sharing, Xuzhou Jing'an Heavy Industry fully demonstrated its technical strength in the field of water conservancy machinery manufacturing, providing strong support for the subsequent technological upgrading of waterproofing construction in water conservancy engineering. Attending guests expressed that they would take this exchange meeting as an opportunity to strengthen cooperation with technology-oriented enterprises such as Jing'an Heavy Industry, and jointly promote Xuzhou's water conservancy engineering construction toward a stage of higher-quality development.
