AI Technical Summary

Technical Problem

Existing composite foundation treatment technologies suffer from problems such as simple superposition of processes, disconnected parameter design, rough construction control, poor shallow reinforcement effect, and low drainage efficiency, which cannot meet the requirements of modern port engineering for efficient, economical, and reliable reinforcement.

Method used

The method of dynamic compaction-mixing pile synergistic reinforcement is adopted. Through site investigation and zoning, pretreatment, measurement and positioning, trial construction in the test area and optimization of key parameters, combined with intelligent monitoring and control, the dynamic compaction energy and mixing pile parameters are optimized in a coordinated manner, forming a highly efficient reinforcement system for deep port soft soil foundation.

Benefits of technology

It significantly improves the bearing capacity and drainage efficiency of composite foundations, shortens the construction period, reduces costs, and enables intelligent monitoring and environmental protection during the construction process. The reinforcement effect is reliable and meets the rapid construction needs of modern port projects.
