On February 16, 2022, the "2022 Annual Geotechnical Engineering Committee Council Meeting of the Beijing Society of Civil Engineering" was successfully held at Beijing Vibration Compaction Engineering Machinery Co., Ltd. in Songzhuang Town, Tongzhou District, Beijing. The main members attending the meeting include:
• Sun Hongwei, Vice President of the Beijing Society of Civil Engineering, Director of the Geotechnical Engineering Committee, and Deputy Chief Engineer of Beijing Architectural Design and Research Institute Co., Ltd.
• Li Weiqiang, Secretary-General of the Geotechnical Engineering Committee of the Beijing Society of Civil Engineering, and Director of the Foundation Engineering Institute of Beijing Architectural Design and Research Institute Co., Ltd.
• Liu Huancun, Chief Engineer of China Aviation Survey and Design Research Institute Co., Ltd.
• Huang Changqian, Chief Engineer of China Aviation Survey and Design Research Institute Co., Ltd.
• Lu Wei, Supervisor of China Power Construction Vibration Compaction Construction Engineering Co., Ltd. • Shui Weihou, General Manager of Dadi Juren (Beijing) Engineering Technology Co., Ltd.
• Dong Bingyin, Deputy General Manager of Dadi Juren (Beijing) Engineering Technology Co., Ltd.
• Zhang Guangbiao, General Manager of Beijing Vibration Compaction Engineering Machinery Co., Ltd.
• Lu Pengyun, Deputy General Manager of Beijing Vibration Compaction Engineering Machinery Co., Ltd.
The meeting was chaired by Secretary-General Li Weiqiang. Vice President Sun Hongwei extended a warm welcome to the experts from participating units and nearly 100 industry professionals attending online via Tencent Meeting, and expressed gratitude to Beijing Vibration Compaction Engineering Machinery Co., Ltd. for organizing and coordinating the meeting. Four experts gave reports on cast-in-place piles, vibro-compaction, and high fill sites during the meeting.
Chief Engineer Liu Huancun of China Aviation Survey and Design Research Institute Co., Ltd.'s report was titled "Bearing Capacity Test of Large-Diameter Cast-in-place Piles and Some Thoughts". Through the recent study on the influence of different ground treatment methods on the bearing capacity of rock-socketed piles in high fill areas, the results show that the pile load is mainly provided by the upper lateral frictional resistance, while the end resistance is relatively small. Bearing capacity tests of large-diameter cast-in-place piles in general clay show that the single-pile bearing capacity is increased by nearly 40% after grouting.
Supervisor Lu Wei of China Power Construction Vibration Compaction Construction Engineering Co., Ltd.'s report was titled "New Progress in Vibro-compaction Technology". It mainly introduced the development history, domestic and foreign manufacturers and product development of vibro-compaction equipment, the application of 70m ultra-deep vibro-compaction stone columns in the cofferdam foundation treatment of the La Wa Hydropower Station, and proposed the combined application with other processes such as CFG piles.
Deputy General Manager Lu Pengyun of Beijing Vibration Compaction Engineering Machinery Co., Ltd.'s report was titled "Discussion on the Significance of Bottom Discharge Technology to the Technology and Market of Vibro-compaction Industry". The report mainly included: the process flow of bottom discharge vibro-compaction, the ground improvement mechanism and inspection and monitoring; and introduced the differences between bottom discharge and traditional vibro-compaction (top filling method), as well as the advantages of suspension method in underwater construction. Combined with the current domestic and international application status, the application in drainage and liquefaction resistance should be further promoted.
Deputy General Manager Dong Bingyin of Dadi Juren (Beijing) Engineering Technology Co., Ltd.'s report was titled "Technical Progress and Engineering Practice of High Fill Site Formation". It introduced the market situation of high fill sites, technical points (three sides and two bodies and two slopes and two waters), engineering practices such as the land creation project in Yan'an New District, and current problems to be solved, such as groundwater drainage.
The participants had in-depth discussions and exchanges on the reported topics.
General Manager Zhang Guangbiao of Beijing Vibration Compaction Engineering Machinery Co., Ltd. said that he would vigorously promote the combination and application of vibro-compaction methods with other methods, hoping to contribute to the development of the geotechnical foundation industry.
Deputy General Manager Feng Zheming of Beijing Vibration Compaction Engineering Machinery Co., Ltd. explained the 260KW vibro-compaction equipment and bottom discharge vibro-compaction equipment.
