AI Technical Summary

Technical Problem

Existing technologies make it difficult to prepare ultrafine particle fluidized solidification materials with high dosage, low water content, and high strength, and lack real-time construction quality monitoring technology, which makes it difficult to coordinate the contradiction between the fluidity and age strength of cohesive solidified soil, and makes it difficult to control the construction quality of cement mixing piles.

Method used

The process employs an ultrafine particle soil fluidizing agent, which includes cement, slag powder, alkaline activator, and organic polymer dispersant. Through an intelligent pile data acquisition and analysis system, construction parameters are monitored in real time. Combined with high-pressure airflow technology, the plastic-fluid transformation of cohesive solidified soil and construction quality control are achieved.

Benefits of technology

It achieves a balance between high fluidity and high strength in cohesive solidified soil, improving construction efficiency and quality control, and offering convenience. It is suitable for reinforcing ultrafine-particle soil materials, reducing cement usage, and enabling the resource utilization of waste materials.
