On November 18, 2022, the fourth National Geotechnical Engineering Construction Technology and Equipment Innovation Forum was successfully concluded in Yixing Taodu Peninsula Hotel. More than 300 experts, scholars, and representatives of geotechnical construction enterprises and equipment manufacturing enterprises attended the conference offline at the Peninsula Hotel, and more than 150 delegates attended the conference online in Shanghai, Shenzhen, Tianjin, Wuhan, Zhengzhou, Kunming and Ningbo. A total of more than 50,000 people watched the conference live via video.

SHJT Construction Machinery Co., Ltd. was invited to co-organize the conference. General Manager Li Liwan, deputy general manager Xu Feng and chief engineer Li Daohua attended the opening ceremony of the conference. Deputy Chief engineer Xie Tian made a special report on the Technical Innovation and Application of Underground pile Wall Construction Equipment at the conference.

Special report on Technical Innovation and Application of Underground Pile Wall Construction Equipment by Xie Tianzuo, Deputy Chief Engineer of SHJ

The report focuses on the achievements of SHJT in the field of pile wall new equipment in recent years, including the substantial achievements of LZ40 intelligent deep mixing (pile planting) drill in a number of large housing construction projects across the country to effectively reduce construction costs, ensure pile quality, improve construction efficiency; The ultra deep vibroflotation gravel drill SV90 has upgraded its capability on the basis of SV70, which achieved the world's deepest vibroflotation gravel pile of 70m. The large-torque hybrid SX50 double-wheel milling machine continues to break the construction depth record of the ultra-deep ground connecting wall in China every year, and has now broken the mark of 143m. In 2023, the Jintai double-wheel milling machine will challenge the 220m ultra-deep ground connecting wall. Share typical cases of SC50 ultra-deep and equal thickness soil-cement mixing wall drill in foundation pit enclosure, dam reinforcement, and construction of anchorage pits and underground sewage treatment projects under special working conditions; The world's largest type SG100 ground wall hydraulic grab line, Shanghai Pudong Jinding commercial culture construction project, and SH60 super large rotary drilling rig broke the construction record of 143m super deep pile. From the very beginning of research and development, these products have locked the special needs of specific projects and specific processes for construction equipment. After repeated application verification and continuous improvement, they eventually form a special product spectrum with unique Jintai characteristics and second to none in the industry, and have created one after another miracles of Chinese construction equipment in major national projects.
