System and method for monitoring and controlling grouting operations
Methods and systems for monitoring and controlling a grouting operation are described. In one aspect, the method includes: performing the grouting operation by injecting grout into a borehole and cyclically: monitoring the borehole pressure until the borehole pressure equals a first pressure threshold; in response to determining that the borehole pressure equals the first pressure threshold, halting the injection of grout into the borehole; monitoring the borehole pressure until the borehole pressure decreases to a second pressure threshold, the second pressure threshold being lower than the first pressure threshold; in response to determining that the borehole pressure equals the second pressure threshold, restarting injection of grout into the borehole, until a terminating condition is satisfied and, as a result, terminating the grouting operation.
