AI Technical Summary
Existing grouting and pressure delivery methods suffer from problems such as grout backflow, blockage, and inaccurate parameter control under complex surrounding rock conditions, resulting in incomplete consolidation and affecting construction safety and efficiency.
A segmented pressure delivery mode is adopted, using grouting pipes with perforations and aluminum foil. By controlling the grouting pressure and short-term shutdown, precise grout delivery and backflow suppression are achieved, and different grout ratios and pressures are combined to adapt to the surrounding rock conditions.
It improved the consolidation density of the surrounding rock, reduced the risk of well wall deformation and collapse, improved construction adaptability and efficiency, and ensured construction safety and quality.
