and S110, placing the drill rod on the anchor grouting anchor rod supporting construction equipment, and feeding a drill box on the anchor grouting anchor rod supporting construction equipment to drive the drill rod to drill.
S120, detecting the feeding pressure of the drill box, and if the feeding pressure is smaller than or equal to a first pressure threshold value, continuing to advance the drill box; and if the feeding pressure is greater than the first pressure threshold value, the drill box drives the drill rod to retreat. The first pressure threshold is a drill box feeding threshold, when the drill box advances to a certain degree, the drill box abuts against a feeding limiting part on the drill arm, or a driving part for driving the drill box to advance reaches a travel limit, or the drilling depth of the drill rod reaches a certain degree, the feeding pressure of the drill box exceeds the first pressure threshold, the fact that the drill box advances in place and the drill rod drills in place is indicated, and the drill box stops advancing and drives the drill rod to retreat.

S150, detecting the feeding pressure of the drill box, and if the feeding pressure is smaller than or equal to a third pressure threshold value, continuing to advance the drill box; if the feed pressure is greater than the third pressure threshold, the drilling box is stopped and the anchoring agent is pumped into the borehole. The third pressure threshold value is also a drill box feeding threshold value, when the drill box advances to a certain degree, the drill box abuts against a feeding limiting part on the drill boom, or a driving part for driving the drill box to advance reaches a stroke limit, or the end part of the anchor rod abuts against the bottom of the drill hole, the feeding pressure of the drill box exceeds the third pressure threshold value, the drill box advances to the place, the anchor rod is placed in the place, the drill box stops advancing and retreats, and the anchor rod is left in the drill hole. The working conditions of the drill box for pushing the drill rod and the drill box for pushing the anchor rod are different, and the third pressure threshold value and the first pressure threshold value can be the same or different.
S160, the drill box is retracted, the retraction pressure of the drill box is detected, and if the retraction pressure is smaller than or equal to a fourth pressure threshold value, the drill box continues to retract; if the feed pressure is greater than the fourth pressure threshold, the drill box is stopped. The fourth pressure threshold is a drill box returning threshold, when the drill box returns to a certain degree, the drill box abuts against a feeding limiting part on the drill boom, or a driving part for driving the drill box to return reaches a stroke limit, the returning pressure of the drill box exceeds the fourth pressure threshold, the situation that the drill box returns to the place is indicated, and the drill box stops returning. In step S130, the drill box drives the drill rod to retract together, and in step S160, the drill box retracts independently, so that the fourth pressure threshold and the second pressure threshold may be the same or different.
