Ye Guoqiang, Secretary-General of Shanghai Civil Engineering Society, first delivered a speech, extending a warm welcome and heartfelt thanks to the representatives of the drafting member units for attending the meeting despite the summer heat. He read the announcement 'On the Approval of the Group Standard for the Standard', announced the establishment of the drafting group and the list of its members, and emphasized the significance of standard development and specific drafting requirements. The purpose of the standard is to regulate the application of micro-disturbance four-axis mixing piles in engineering, ensuring safety, reliability, quality assurance, economic rationality, and environmental protection. It is applicable to the design, construction, quality, and acceptance of micro-disturbance four-axis mixing piles.

The meeting focused on detailed discussions of the seven chapters (draft) of the Standard: 'Terms and Symbols', 'Basic Provisions', 'Equipment', 'Design', 'Construction', 'Digital Management and Evaluation', and 'Inspection and Acceptance'.
