[0083] S3: when D>600kPa, it means that the current depth is hard soil layer, and it is high hardness state, in the high hardness state, the value of F is not referenced, and the low rotation speed of the drill rod 9 and the high amplitude and high frequency of the vibration blade 12 are operated; the low rotation speed can improve the torque of the vibration blade 12, and avoid overload; the high amplitude and high frequency can improve the impact force and crushing effect of the vibration blade 12 on the hard soil.

[0084] The depth of the drill rod 9 is monitored by the laser ranging sensor, and when the retraction stroke of the hydraulic telescopic cylinder 24 does not meet the pit depth, the output end of the hydraulic telescopic cylinder 27 is controlled to retract, and the fixed plate 26 continues to descend, so that the drill rod 9 can continue to drill soil downward;
