Description
Technical field
The utility model relates to a kind of TBM cutterhead, advance borehole device in especially a kind of TBM cutterhead.
Background technique
With national project build in major long tunnel construction it is more and more, TBM is existed due to efficient, environmentally friendly, safe feature
It is widely adopted in tunnel construction.Currently, often due to country rock weak broken, being caused when TBM driving passes through unfavorable geology section
Occur that TBM cutterhead and shield by card phenomenon.Traditional leading pre-supporting measure by TBM shield due to being influenced not making in face
Industry, and it is undesirable to perform advance reinforcement measure effect from shield rear direction face, can only band to be broken expose behind shield top again
It is handled, this belongs to post-processing, does not have the purpose of advance reinforcement prevention card machine.
Utility model content
The purpose of this utility model is just to provide advance borehole device in a kind of TBM cutterhead for being able to carry out pre support.
The purpose of this utility model is that technical solution in this way is realized, advance borehole device in a kind of TBM cutterhead,
Including the shield being arranged on girder, one end of the shield is provided with cutterhead, is set on the girder and in shield
It is equipped with advance borehole device, the reserved drilling with the cooperation of advance borehole device is provided on the cutterhead.
Wherein, the advance borehole device includes frame body, and one end of the frame body is connected by shaft and connecting pin and girder
It connects；A pair of of oil cylinder is provided in the frame body, the fixing end of the oil cylinder and one end of frame body connect, and the oil cylinder stretches
End is provided with wheel group, is provided with chain in the wheel group, is provided with drilling machine on the chain, is provided on the drilling machine
The drilling rod of one end stretching frame body.
It further describes, the chain arranges that the wheel group includes multiple gears, and the gear is located at chain in S shape
On the inside of bending.
In order to control the bore angle of drilling machine, a pair of of support cylinder is provided on the girder, the support cylinder
Telescopic end is connect with frame body.
By adopting the above-described technical solution, the utility model has, structure is simple, uses reliable, easy to operate, cost
Cheap advantage, using it can the crushed zone to different angle carry out drilling advance reinforcement, play the purpose of pre support, prevent
Cutterhead is stopped and shield occurs by card phenomenon.
Detailed description of the invention
The Detailed description of the invention of the utility model is as follows:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the advance borehole device side view of the utility model；
Fig. 3 is the advance borehole device top view of the utility model.
Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing, but the utility model
These embodiments are not limited to, any improvement or substitution on the present embodiment essence spirit still falls within the utility model
Claim range claimed.
Embodiment 1: as shown in Figure 1, advance borehole device in a kind of TBM cutterhead, including the shield 2 being arranged on girder 1,
One end of the shield 2 is provided with cutterhead 3, is provided with advance borehole device on the girder 1 and in shield 2,
The reserved drilling 4 with the cooperation of advance borehole device is provided on the cutterhead 3.
In TBM tunneling process, 3 front country rock weak broken of cutterhead is found, have collapsing or deformation hidden danger, at this point, in knife
Grouting Pipe grouting and reinforcing is applied to 3 front of cutterhead and periphery by the reserved drilling 4 on cutterhead 3 using advance borehole device in disk
Weak-fracture zone, every one ring of pre-reinforcement, TBM pushes ahead a circulation, then carries out the pre-reinforcement of subsequent cycle, so anti-
Multiple, TBM passes through fractured weak zone.
As shown in Figure 2,3, wherein the advance borehole device includes frame body 5, and one end of the frame body 5 passes through 6 He of shaft
Connecting pin 7 is connect with girder 1；A pair of of oil cylinder 8, the fixing end of the oil cylinder 8 and the one of frame body 5 are provided in the frame body 5
End connection, the telescopic end of the oil cylinder 8 is provided with wheel group 9, is provided with chain 10 in the wheel group 9, on the chain 10
It is provided with drilling machine 11, the drilling rod 12 that frame body 5 is stretched out in one end is provided on the drilling machine 11.
It further describes, the chain 10 is arranged in S shape, and the wheel group 9 includes multiple gears, and the gear is located at chain
On the inside of 10 bending.
When needing to drill, the oil cylinder 8 in frame body 5 works, and band driving wheel group 9 works, so that 9 draw chain 10 of wheel group moves
Dynamic, mobile chain 10 drives drilling machine 11 to be moved forward and backward, meanwhile, the work of drilling machine 11 drives drilling rod 12 to drill.
In order to enable advance drilling machine has different bore angles, a pair of of support cylinder 13 is provided on the girder 1,
The telescopic end of the support cylinder 13 is connect with frame body 5.
