Embodiment 1
[0150] In this embodiment, the CO2 micro-explosion combined TBM rock-breaking device 1 includes a cutterhead mechanism 2, a drilling rig installation mechanism 3 and a CO2 blasting device installation mechanism 4; the drilling rig installation mechanism 3 and the CO2 blasting device installation mechanism 4 are alternately arranged on the cutterhead mechanism 2 Above; the cutterhead mechanism 2 is installed on the TBM main bearing; the belt conveyor 5 is installed on the support frame 6; the belt conveyor 5 is located behind the cutterhead mechanism 2.
[0151] The cutterhead mechanism 2 includes a positive cutterhead 2.1 and a side cutterhead 2.2;
[0152] The side cutter head 2.2 is located on the outer periphery of the front cutter head 2.1;
[0153] The drilling rig installation cylinder 3.2 of the drilling rig installation mechanism 3 and the CO2 installation cylinder 4.2 of the CO2 blasting device installation mechanism 4 are alternately arranged on the positive cutter h...
Embodiment 2
[0164] Its CO2 micro-explosion combined TBM rock-breaking device 1 and its rock-breaking method are the same as in Embodiment 1, the difference is that the rock mass in this embodiment is through a certain blasting and cutting, and the contour of the tunnel surface formed at last is uneven ( As shown in Figure 30), then there is a difference in the stroke of the drilling rod of the drilling rig in the rock mass.
[0165] In this embodiment, a depth measurement sensor is set on the drilling rig (being the prior art); in this embodiment, the depth data of the actual drilling of the drilling rig is obtained by the depth measurement sensor on the drilling rig, and according to the depth data, the next stage CO2 The filling amount of the blasting device and the length of the blasting tube are adjusted; Figure 30 Among them, the actual working footage of the drilling rigs in area A is smaller than the actual working footage of the drilling rigs in area B. The adjustment method in t...
Embodiment 3
[0167] Its CO2 micro-explosion combined TBM rock-breaking device 1 and its rock-breaking method are the same as in Embodiment 2, the difference is that in this embodiment, the contour of the tunnel face is an inclined structure or a rotating structure (such as Figure 31 shown); in Figure 31 Among them, the actual working footage of the drilling rigs in area C is greater than the actual working footage of the drilling rigs in area D. The adjustment method in this embodiment is: when the TBM turns, the drilling length in area C is greater than that in area D. When the CO2 blasting device is in the next stage, The filling amount of CO2 gas is adjusted according to the depth of the drill hole, that is, the length of the CO2 blasting tube and the CO2 filling amount in the C blast hole area are greater than that in the D blast hole area.
[0168] Other unspecified parts belong to the prior art.
