Detailed description of the invention
As Figure 1-5, ultrahigh pressure auxiliary rock TBM cutterhead described in the utility model, including TBM cutterhead originally
Body, multiple disk cutters 2 that described TBM cutterhead body by cutterhead 1, is arranged on described cutterhead 1 work surface and be distributed on cutterhead
Four slag gathering hoppers 3 on 1 work surface edges form；Running orbit coil 4 quantity of the plurality of disk cutter 2 be five circles (see
In Fig. 3 shown in double dot dash line)；Being provided with multiple shower nozzle 5 on described cutterhead 1 work surface, the plurality of shower nozzle 5 is respectively along described dish
The running orbit coil 4 of shape hobboing cutter 4 is arranged or is close to running orbit coil 4 and arranges, and is arranged in the advance that disk cutter 2 runs
Direction；As shown in Figure 1-2, the back side at cutterhead 1 be provided with the water supply swivel coupling 7 for connecting outer water tube 6, for
The powered communication swivel coupling 8 of TBM main control room electrical connection and cutterhead fixed mount 9, described water supply swivel coupling 7, power supply are led to
Letter swivel coupling 8 is positioned at the centre of gyration of cutterhead 1；Described cutterhead fixed mount 9 is provided with by ultrahigh pressure filter, front
Put feed pump, increase pump, accumulator, power motor and the central control unit 10 of electric-control system composition；Described water supply revolution connects
7 are connected with the ultrahigh pressure filter in central control unit 10 by water supply line 11, in central control unit 10
Accumulator be connected with each shower nozzle 5 water inlet by high pressure alloy pipeline 12；Described powered communication swivel coupling 8 is by supplying
Electric line and communication line are electrically connected with the power motor in central control unit 10 and electric-control system.
Fig. 4 gives the structural representation of shower nozzle 5, and nozzle 13 inwall of shower nozzle 5 is coated with wearing layer to improve wearability
Energy；The nozzle 13 diameter d(mm of shower nozzle 5), according to the engineering application state analysis of ultrahigh pressure fluidics the most both at home and abroad,
The diameter d(mm of this utility model nozzle 13) according to engineering surrounding rock situation, choose in the range of 0.1mm～0.5mm, then through examination
Determine after testing research.The determination of operating pressure p (MPa) of shower nozzle 5, owing to ultrahigh pressure jet directly acts on TBM area
Face rock, therefore operating pressure p takes the saturated compression strength value of country rock of 1.5～2.0 times, but maximum less than 400MPa(because
The high-pressure bottle manufacturing cost of more than 400MPa is the highest, less economical).Other parameter of shower nozzle 5, such as nozzle flow velocity vt, penetrate
The determination of stream flow q, jet power P etc., can be according to the theoretical calculation formula of ultrahigh pressure jet, according to selected nozzle
Diameter d, operating pressure p and nozzle layout of sprinkler carry out calculating and determine.
Utility model works principle is summarized as follows:
The thrust that tradition TBM provides only with main thrust oil cylinder is by hobboing cutter injection rock, and disk cutter is along with the fortune of cutterhead
Dynamic and passively roll and cut, extruding, fractured rock, thus realize tunnel drivage excavation.
This utility model is to arrange suitable ultrahigh pressure shower nozzle 5 on tradition TBM cutterhead, and shower nozzle 5 is positioned at dish type rolling
The direction of advance of cutter 2 movement locus line.Start ultrahigh pressure spraying system starting while cutterhead 1 rotates, pass through nozzle
The supertension overflow of 13 ejections carries out hydraulic blow shearing to face rock, and ultrahigh pressure jet produces two works to rock
With: 1, ultrahigh pressure failure by shear forms annellation；2, ultrahigh pressure sputtering, slabbing action, make rock formation between annellation micro-
Crack or make in rock microcrack development, become big.Along with the rotation of cutterhead 1, disk cutter 2 is pressed into the area developing microcrack
In the rock of face, and cut, extrude, fractured rock, thus realize tunnel drivage excavation；Thus pressure simple for tradition TBM is passed through
Enter to change into the compound injection of " high-pressure hydraulic+pressure ", reduce disk cutter 2 injection thrust, reduce the mill of disk cutter 2
Damage.
