Description
Technical field
The present invention relates to tunnel hard rock mole (TBM), more particularly, to the TBM cutterhead for having PDC drill bit auxiliary rock.
Background technique
Now across basin, it is trans-regional draw, in water diversion project, (the western line Tunnel length in such as China is more than for long tunnel
It is often 200km) that the first choice of engineering draws (defeated) water buildings, under conditions of landform, geological conditions limitation, is applied to improve tunnel
Work speed shortens the duration of a project, and first choice is constructed using TBM.Traditional TBM passes through hobboing cutter only with the thrust that featured power cylinder provides
Enter rock, hobboing cutter is passively rolled and cut with the movement of cutterhead, squeezed, fractured rock, to realize that tunnel drivage is excavated.
It is counted according to existing engineering data, traditional average drill footage per month of TBM construction is 500mm.But when rock uniaxiality strength is more than
When 120MPa, the pile penetration of TBM is extremely low and tool wear is serious, prevent TBM high efficiency causes TBM to construct from giving full play to
Efficiency degradation.
Summary of the invention
It is an object of that present invention to provide a kind of TBM cutterhead for having PDC drill bit auxiliary rock, reaches and quickly carry out tunnel pick
Into excavation, while abrasion of the rock to hobboing cutter is reduced, improve TBM drivage efficiency, extends disk cutter service life.
To achieve the above object, the present invention takes following technical proposals:
The TBM cutterhead of the present invention for having PDC drill bit auxiliary rock, including TBM cutterhead body, the TBM cutterhead body by
Cutterhead, the multiple disk cutters being arranged on the cutterhead working face, four scraper bowl groups being evenly arranged on cutterhead work surface edges
At；The running track line of multiple disk cutters is annular；Multiple PDC drill bits are provided on cutterhead working face, it is multiple described
PDC drill bit is arranged along the running track line arrangement of the disk cutter or between two running track lines respectively, and is arranged in
The direction of advance of disk cutter operation；The back side of cutterhead is provided with water supply swivel joint for being connected to external water source, is used for
With the power supply swivel joint and cutterhead fixed frame of the electrical connection of TBM main control room, the water supply swivel joint, power supply swivel joint
Positioned at the centre of gyration of cutterhead；The water supply swivel joint passes through the water being arranged near PDC drill bit on water supply line and cutterhead
Power nozzle is connected；The power supply swivel joint is electrically connected by power supply line and the TBM main control room.
The present invention by absorbing, using for reference the PDC drill bit breaking technique for rock of the industries such as petroleum, by the driving technology of traditional TBM and
PDC drill bit breaking technique for rock combines, and forms the TBM cutterhead of PDC drill bit auxiliary rock, provides for superhard rock construction of tunnel
A kind of construction equipment of new high efficiency.Its advantage embodies in the following areas:
1, in tunneling process, the extruding of the cyclic annular grooving and disk cutter that are formed by PDC drill bit generates efficient coupling, greatly improves
The pile penetration of disk cutter reduces TBM thrust, simplifies body thrust structure arrangement；
2, since PDC drill bit is from boring and following the microcrack and grooving that are formed in cutterhead rotation process, dish type rolling is considerably increased
Knife radially efficiency of breaking rock, reduces disk cutter resistance and tool wear, so that disk cutter service life to a certain extent
Extended；
3, when encountering super ground consisting of hard rock in tunneling process, TBM construction efficiency can be integrally improved, reduces equipment energy consumption；
4, reduce since disk cutter is worn, replacement cutter number is totally reduced, and saves the operation and maintenance cost of TBM equipment.

Specific embodiment
As shown in Figs. 1-5, the TBM cutterhead of the present invention for having PDC drill bit auxiliary rock, including TBM cutterhead body,
TBM cutterhead body by cutterhead 1, the multiple disk cutters 2 being arranged on 1 working face of cutterhead, be evenly arranged on cutterhead work surface edges
Four scraper bowls 3 composition；The running track line 4 of multiple disk cutters 2 is annular；Multiple PDC are provided on 1 working face of cutterhead to bore
First 5 and hydrojet nozzle 10, multiple PDC drill bits 5 arrange (as shown in Figure 3) along the running track line 4 of disk cutter 2 respectively, or transport
Between row trajectory line 4 arrange (as shown in Figure 4), and be arranged in disk cutter 2 run direction of advance, hydrojet nozzle 10 close to
PDC drill bit 5 is arranged；The back side of cutterhead 1 is provided with water supply swivel joint 6 for being connected to external water source, is used for and TBM master control
The power supply swivel joint 7 and cutterhead fixed frame 8 of room electrical connection processed state water supply swivel joint 6, power supply swivel joint 7 is located at knife
The centre of gyration of disk 1；Water supply swivel joint 6 passes through the hydrojet nozzle being arranged near PDC drill bit 5 on water supply line and cutterhead 1
10 are connected, and are supplied water by TBM cutterhead spray system pipeline 9；Swivel joint 7 of powering passes through power supply line 11 and TBM main control room
Electrical connection.
Working principle of the present invention is summarized as follows:
When tunnel drivage, starting PDC drill bit 5 and hydrojet nozzle 10,5 high speed rotation of PDC drill bit while starting cutterhead rotation
Face rock cut being crushed and forms grooving；With the rotation of cutterhead 1, the indentation of disk cutter 2 has generated fine fisssure seaming and cutting
It in the face rock of slot, and cuts, squeeze, fractured rock, rock assists grooving and the cutting of disk cutter 2 to squeeze in PDC drill bit 5
Rapid deterioration under collective effect is pressed to be detached from rock mass, rock slag enters slag tap belt conveyer by scraper bowl 3, to realize tunnel speedy drivage
Construction.Meanwhile the compound injection of " cutting+pressure " is changed into the simple pressure injection of traditional TBM cutterhead by the present invention, is reduced
2 injection thrust of disk cutter, reduces the abrasion of disk cutter 2.
PDC drill bit power supply system is connected to TBM main control room using wired mode by power supply swivel joint 7, convenient for pair
PDC drill bit 5 assists grooving to be monitored.
