The embodiment of the invention provides a TBM (tunnel boring machine), which comprises a cutter head 1, a main drive and a shield, wherein the cutter head 1 is provided with a plurality of advanced processing holes 11, and the main drive and the shield are respectively provided with a drill pipe guide 2 corresponding to each advanced processing hole 11; the rear end of the shield is provided with a drilling machine 3, and a drill rod of the drilling machine 3 can penetrate through the corresponding drill rod guide pipe 2 and the advanced processing hole 11 so as to detect the excavated tunnel face of the cutter head 1.
In the process of excavating by adopting the TBM method, a drill rod can sequentially penetrate through the drill rod conduit 2 and the corresponding advanced processing hole 11 so as to realize the detection of the stratum condition at the front end of the cutter head 1; when extremely hard rock or the situation that local rock is hard during tunneling and the overall strength of surrounding rock in a tunneling area is low is met, a drill rod sequentially penetrates through a drill rod guide pipe 2 and a corresponding advanced processing hole 11, advanced drilling is carried out on the rock at the front end of a cutter head 1 by using the drill rod, and micro drilling blasting is preformed, so that the abrasion of the extremely hard rock on a cutter of the cutter head 1 is reduced, the cutter head 1 is prevented from being clamped due to the collapse of local large rocks, and the influence of high rock blasting and blocking machines on TBM during tunneling is reduced; when water-rich or weak surrounding rocks are encountered, advanced grouting reinforcement can be realized by utilizing the drill pipe guide pipe 2 and the advanced treatment hole 11.
Therefore, in the embodiment, the advanced treatment holes 11 are reserved in the cutter head 1, the drill rod guide pipes 2 are respectively embedded in the main drive and the shield, and the drill rod of the drilling machine 3 sequentially passes through the drill rod guide pipes 2 and the advanced treatment holes 11, so that the drill rod can reach the front end of the cutter head 1, and the rock at the front end of the cutter head 1 can be detected or treated, so that the detection and intervention range of the TBM is wider, the detection and pretreatment of the face of the cutter head 1 can be directly implemented, the advanced geology can be detected, the complex and variable advanced geology can be treated pertinently, the combined construction of the drilling and blasting excavation method and the TBM excavation method can be realized, the drilling and blasting are integrated, the working efficiency is improved, and the defects that the traditional drilling and blasting excavation method is insufficient in personnel protection, the working strength is high, the efficiency is low and the like are overcome.
It should be noted that, in this embodiment, the number, distribution, and the like of the advance processing holes 11 reserved in the cutter head 1 are not specifically limited, and in principle, the advance processing holes 11 should cover the tunnel face excavated by the cutter head 1 as completely as possible. Accordingly, the drill rod guide pipes 2 are required to correspond to the advanced treatment holes 11 one by one, so that the drill rod guide pipes 2 can provide guiding and supporting functions for the drill rods, and the drill rods can smoothly pass through the advanced treatment holes 11.
In some embodiments, the pilot hole 11 includes a plurality of first pilot holes 111 distributed along the same circumference, and the axes of the first pilot holes 111 are arranged parallel to the axis of the cutter head 1. That is, the axis of the first advanced treatment hole 111 is parallel to the boring direction, which is advantageous for horizontal drilling of the drill rod. Of course, after the drill rod comes out of the drill rod guide tube 2, a certain included angle may be formed between the drill rod and the first advanced processing hole 111, for example, the included angle between the drill rod and the axis of the first advanced processing hole 111 is within 8 degrees, so as to implement advanced drilling processing on the rock at the front end of the cutter head 1 within 8 degrees of the included angle in the tunneling direction.
Further, in some embodiments, the pilot holes 11 include a plurality of second pilot holes 112 distributed along the same circumference, and the axes of the second pilot holes 112 and the axis of the cutter head 1 have a predetermined included angle therebetween. The advance drilling device is beneficial to realizing the advance drilling of the drill rod with a preset external insertion angle or a preset internal insertion angle.
In some embodiments, the radius of the circumference in which the second advanced processing hole 112 is located is greater than the radius of the circumference in which the first advanced processing hole 111 is located. That is, the pilot hole 11 covers the tunnel face excavated by the cutter head 1 as much as possible by the first pilot hole 111 and the second pilot hole 112 provided in the circumferences of different radii.
Further, in some embodiments, the pilot holes 11 include a third pilot hole 113, and the third pilot hole 113 is disposed at a predetermined position near the center of the cutter head 1 to correspond to the center of the tunnel. That is, the center of the tunnel may be drilled by using the drill rod through the third advanced processing hole 113.
In order to enable the drill rods of the drilling machine 3 to cover all the advance processing holes 11, in some embodiments the rear end of the shield is provided with a ring beam 4, along which ring beam 4 the drilling machine 3 is movably arranged to the ring beam 4. That is, the drilling machine 3 is arranged on the annular beam 4, and the annular beam 4 is used for supporting the drilling machine 3; at the same time, the drilling machine 3 can be moved along the ring beam 4 to adjust the position of the drilling machine 3 so that the drill rods can be passed through the different advanced treatment holes 11.
In some embodiments, the ring beam 4 is arranged on the main beam at the tail of the shield.
In order to enable the drilling machine 3 to accommodate advanced handling holes 11 on different circumferences, in some embodiments the ring beam 4 is provided with an outer ring gear 41 and an inner ring gear 42; the drilling machine 3 comprises a first drilling machine 31 and a second drilling machine 32, wherein the first drilling machine 31 is provided with a first gear 311 meshed with the outer gear ring 41, the second drilling machine 32 is provided with a second gear meshed with the inner gear ring 42, and the first gear 311 and the second gear are both connected with a driving motor 312. It will be appreciated that rotation of the drive motor 312 connected to the first gear 311 causes the first gear 311 to rotate along the outer gear ring 41 in a meshing manner, thereby moving the first drilling machine 31 along the outer gear ring 41 to advance the drill rod through each advanced processing hole 11 of the outer ring, for example, the second advanced processing hole 112 mentioned above. When the driving motor 312 connected with the second gear rotates, the second gear is driven to rotate along the inner gear 42 in an engaged manner, so that the second drilling machine 32 moves along the inner gear 42, so that the drill rod corresponds to each advance processing hole 11 of the inner ring, for example, the first advance processing hole 111 in the above. That is, in the present embodiment, by providing the outer ring gear 41 and the inner ring gear 42, and providing the first drilling machine 31 and the second drilling machine 32, the first drilling machine 31 and the second drilling machine 32 perform advance detection processing through advance processing holes 11 on different circumferences, respectively, so as to ensure that the drilling machine 3 has a suitable movement range, which is beneficial to structural layout, and improve work efficiency.

In some embodiments, the number of first rigs 31 is greater than the number of second rigs 32. Since the first drilling machine 31 moves along the outer ring gear 41, the moving radius of the first drilling machine 31 is larger corresponding to the leading processing hole 11 which is further outside, and therefore, by providing a larger number of first drilling machines 31, the working efficiency can be improved.
In some embodiments, the number of first drilling machines 31 is two and the number of second drilling machines 32 is one. Therefore, the cost can be saved as much as possible while the working efficiency is improved.

That is, when the first drilling machine 31 moves along the outer gear ring 41, the first guide wheels 313 on the two sides of the outer rail 43 slide along the two sides of the outer rail 43 respectively, and the outer rail 43 is located between the first guide wheels 313 on the two sides, so as to guide the first drilling machine 31 and ensure the smoothness of the movement of the first drilling machine 31. Similarly, when the second drilling machine 32 moves along the inner gear ring 42, the second guide wheels on the two sides of the inner rail 44 respectively slide along the two sides of the inner rail 44, and the inner rail 44 is located between the second guide wheels on the two sides, so that the second drilling machine 32 is guided, and the movement stability of the second drilling machine 32 is ensured.
In addition, in order to avoid the first drilling machine 31 and the second drilling machine 32 from being offset relative to the ring beam 4, in some embodiments, the first drilling machine 31 and the second drilling machine 32 are each provided with at least one pair of anti-deflection wheels 314, and the two anti-deflection wheels 314 of the same pair are respectively in contact with both sides of the ring beam 4. That is, the ring beam 4 is clamped between the two anti-deviation wheels 314 of the same pair, and the anti-deviation wheels 314 are matched with the two sides of the ring beam 4 for limiting, so that the first drilling machine 31 and the second drilling machine 32 are prevented from being deviated relative to the ring beam 4.
Additionally, to facilitate adjusting the position of the drill rods, in some embodiments, the first drilling machine 31 and the second drilling machine 32 each include an adjustment mechanism for adjusting the position of the drill rods.

The front and rear lift cylinders 315 and 316 are respectively used for realizing the pitching motion of the first drilling machine 31; the first horizontal compensation cylinder 317 is used to realize the back and forth movement of the first drilling machine 31.
