Ultrasonic inspection of pile foundation of a bridge project to identify deficiencies in the quality, confirmed by drilling core review specific issues of quality defects of pile body; Then uses the core pore water pressure test, on pile foundation defect to wash slurry and dredge the channel and Grout; Finally, Grouting piles meet the regulatory requirements. This specifically described using core-drilling Grouting mending pile body defect, improving the strength of pile body treatment.
