AI Technical Summary
Deep foundation pit construction presents safety hazards such as slope instability, sand and water inrush, and excessive settlement of surrounding buildings and structures. In addition, drainage efficiency is low and the construction sequence is not precise, resulting in high construction safety risks and low efficiency.
A systematic hazard identification and control system is adopted, combined with a combination of cast-in-place pile support and triaxial mixing pile water-stop curtain, and a drainage system that combines well dewatering and open drainage. The excavation is carried out in layers and sections with dynamic monitoring to ensure that the groundwater level is controlled below the excavation surface, and the soil removal route is optimized by reasonable zoning.
It has achieved safety control throughout the entire deep foundation pit construction process, avoiding safety accidents, ensuring safety and efficiency during construction, reducing cross-process interference, improving construction efficiency, and is suitable for complex geological and special climatic environments.
