[0061] As a further embodiment of the present invention, the specific process of using the above-mentioned pressure auxiliary monitoring device to monitor and regulate the pressure of the cut ring in a direct-controlled slurry shield machine is as follows:

[0062] Step 1: Based on detailed geological surveys (geology, hydrology, proposed tunnel conditions, and other data), calculate the theoretical pressure Pm (Pmin-Pmax) of the cut ring. The minimum theoretical pressure Pmin ensures that the tunnel face does not collapse backward (in the direction of the shield machine), and the maximum theoretical value Pmax ensures that the tunnel face does not collapse forward (in the direction of the shield machine excavation).

[0063] Step 2: Based on the selected shield type (a direct-controlled slurry shield in this case), set the peak pressure fluctuation value Pb (Pb1-Pb2) of the cut ring during normal tunneling of the shield machine. Pb is determined by the characteristics of the shield machine itself (in this case, it is set to -0.5 bar to 0.5 bar).

[0064] Step 3: According to the calculated theoretical pressure Pm of the cut ring and the peak value of the pressure fluctuation Pb of the cut ring, the cut ring control pressure Pk (Pk1-Pk2) is set during normal tunneling of the shield machine;

[0065] Where: Pk = Pm - Pb, that is:

[0066] Pk1=min[Pmin-Pb1=Pmin+0.5bar, Pmax-Pb2=Pmax-0.5bar];

[0067] Pk2=max[Pmin-Pb1=Pmin+0.5bar, Pmax-Pb2=Pmax-0.5bar];

[0068] Step 4: According to the set incision ring control pressure Pk during normal tunneling of the shield machine and the safety threshold ΔP, the regulating pressure Pt=Pk+ΔP is set;

[0069] The regulating pressure of the valve opening threshold of the first pressure regulating valve group Pt1=Pk2+ΔP1;

[0070] The regulating pressure of the valve opening threshold of the second pressure regulating valve group Pt2=Pk2+ΔP2;

[0071] The regulating pressure of the valve opening threshold of the third pressure regulating valve group Pt3=Pk2+ΔP3;

[0072] Step 5: Compare the pressure values ​​P (P1, P2, P3) measured by the monitoring module 300 with the regulated pressure values ​​Pt (Pt1, Pt2, Pt3) one by one. When P≤Pt, the pressure regulating valve group is closed; when P>Pt, the pressure regulating valve group is opened to release pressure (to prevent risks such as forward instability collapse or roof collapse of the tunnel face);

[0073] As described above, when P≤Pt and P<Pk1, the monitoring module simultaneously adjusts the speed of the slurry pump and the slurry discharge pump (increases the speed of the slurry pump and decreases the speed of the slurry discharge pump) to ensure that P≥Pk1 (to prevent the palm face from becoming unstable and collapsing backward).

[0074] in:

[0075] Pm is the theoretical pressure of the cut ring Pmin-Pmax obtained from detailed geological survey;

[0076] Pb is the peak value of the control pressure fluctuation of the direct-controlled slurry shield machine, Pb1-Pb2;

[0077] Pk is the control pressure Pmin, Pb1≤Pk≤Pmax, Pb2 set according to Pm and Pb;

[0078] Pt: The regulated pressure Pt=Pk+ΔP is set based on Pk and the safety threshold ΔP.
