Further, preferably, the grouting of S6.3.5 in the step S6.3 requires control of the grouting pressure, irrespective of other factors,
Typically, the grouting pressure needs to be greater than the suction slurry pressure to ensure that the grouting material is sufficiently filled into the fracture;
Setting a length matrix of a slurry conveying pipeline of the intelligent control system as L0, and setting a suction pressure matrix generated by a suction device as P0;
setting a length matrix L0 (L1, L2, L3, L1< L2< L3) of the telescopic hose, wherein a suction pressure matrix generated by the suction device is P0 (P1, P2, P3, P1< P2< P3);
according to the relation between grouting pressure and flow in grouting pipeline and pipeline length:
P＝(f*Q*L)/A
wherein P represents grouting pressure, Q represents flow, L represents pipeline length, A represents pipeline sectional area, and f is friction resistance coefficient;
According to the above, f and Q are quantitative irrespective of other factor variations, so when the length of the slurry delivery pipe=the initial length of the telescopic hose l, then the initial grouting pressure p= (f×q×l)/a;
when the length of the slurry delivery pipe=the initial length L1 of the telescopic hose, then the initial grouting pressure p1' = (f×q×l1)/a; p1' < P1, at this time, suction pressure P1 generated by the suction device is used;

When the length of the slurry delivery pipe=the initial length L3 of the telescopic hose, then the initial grouting pressure p3' = (f×q×l3)/a; p3< P3', at this time, stopping the machine and readjusting the slurry square bin angle and the swing relative position;
Since the length of the slurry conveying pipeline is the sum of the initial length of the flexible hose and the fluctuation amount of the first electric push rod, namely l0=l+l0, wherein L is the initial length of the flexible hose, and L0 is the fluctuation amount of the first electric push rod, l1=l+l1; l2=l+l2; l3=l+l3, so the intelligent control system can control the suction pressure generated by the suction device according to the fluctuation amount of the first electric push rod.
