Abstract:

As a main method to cope with highpressure waterrich fault zones, advance grouting can seal ground water gushing, reinforce fractured surrounding rocks, control construction risks and protect surrounding environment. Advance grouting, however, is not the favorite method to be adopted in complex stratum, due to its long time duration and high cost. An innovative design concept of informationaided grouting is proposed on basis of the design concept of traditional advance grouting. Grouting equipment matching, grouting method, grouting material and grouting effect assessment of the innovative method are systematically studied. In the end, rapid grouting is guaranteed in highpressure waterrich fault zones.
