AI Technical Summary
Technical Problem
Conventional techniques for immobilizing groundwater plumes, managing mine water in high hydraulic conductivity areas, and constructing in-situ cutoff walls and diversion structures are inadequate.
Method used
Utilizing colloidal silica to form a stable gel matrix that acts as a semi-permeable or solidified barrier, reducing groundwater flow and immobilizing contaminants by injecting and activating colloidal silica in situ, forming in-situ cutoff walls and diversion structures.
Benefits of technology
Significantly reduces groundwater flow and contaminant migration, providing effective and sustainable groundwater control and containment structures with minimal maintenance and cost-effective solutions.
