Description
Technical field
The present invention relates to tunnels and underground engineering fields, in particular to complex geological condition TBM constructing tunnel field.More
Say it is to body thread hob hydraulic-mechanical TBM cutterhead combined-breaking rock method.The invention further relates to thread hob waterpower-machines
The TBM digging device that tool TBM cutterhead combined-breaking rock method uses.
Background technique
Traditional TBM using mechanical hobboing cutter broken rock, TBM hob in broken rock often tool there are three types of state, i.e., pile penetration it is too small,
Pile penetration is suitable and pile penetration is excessive.
Under certain hobboing cutter spacing condition, when pile penetration is too small, the crackle generated below cutterhead can be to the broken rock scope of freedom
The rock slag piece of triangle is expanded and formed on (face), and also or horizontal direction crackle caused by two-phase neighbour's hobboing cutter can not be handed over
It converges, the phacolith between hobboing cutter can not be cut destruction, and needing to be repeated several times broken rock can be only achieved good rock breaking efficiency, but this side
Method will cause the increase of broken rock energy consumption, influence efficiency of breaking rock；
Under certain hobboing cutter spacing condition, when pile penetration is excessive, the rock between adjacent hobboing cutter is cut to tiny rock
Rock ballast piece, particle even powder, by overcrushing, the increase and cutter for causing energy consumption are ground rock；
Suitable pile penetration, with the smallest energy consumption and mechanism wear, should be formed maximum under certain hobboing cutter spacing condition
Broken rock range.
The normal section disk cutter broken rock pile penetration of tradition machinery is determined by TBM parameter, for different face lithology kinds
Class can adjust；However, due to being difficult to find suitable TBM pile penetration in work progress, so be easy to causeing TBM cutting energy
The loss of amount and the abrasion of cutterhead.
The conventional hob-cutter structure used in existing TBM rock breaking method, the first broken rock mode are as follows: rolled using common roller type
Knife broken rock；Second of broken rock mode are as follows: punching case fills water-jet flow structure at random on TBM cutterhead blank position, makes water jet knot
Structure and common roller type hobboing cutter arranged for interval, using waterpower and mechanically combining broken rock；
But broken rock is carried out using the first above-mentioned broken rock mode, maximum, force needed for destroying rock is larger, and rolling easy to wear
Knife, efficiency of breaking rock are lower；
Broken rock is carried out using above-mentioned second of broken rock mode, such as application No. is: 201310188881.X, patent name are
" method for arranging and structure of the high-pressure water jet in development machine cutterhead "；Its on the basis of traditional TBM cutterhead body structure type,
Several hydraulic sprays are arranged at random in the blank position of TBM cutterhead, there is the efficiency of breaking rock for improving TBM, reduce cutterhead temperature,
To environment dust-proof temp-lowering；But due to the aperture that it need to specially open up installation high-pressure water knife on TBM cutterhead, structure is complicated, with
Machine-to-machine tool hobboing cutter cools down, and does not have specific aim and easily cause water resource waste, broken rock since it is in normally open
Energy consumption is higher, and expected effects are not achieved；
China Patent No.: CN105736006A, patent name are " high-pressure water jet full face rock tunnel boring machine cutterhead design
Method ", inventor Huo Junzhou, Zhu's winter etc. disclose a kind of shape for changing typical round cutterhead, using two cross spokes
Item layout, the rock out machine knife of catalase is carried out by the rotary squeezing of the impact of water jet on four spokes and cutter
Disk is embodied in cutterhead arrangement, reduces broken rock energy consumption；But it is larger to the overall structure form change of cutterhead, industrial
Achievable degree is not high.
With society it is increasingly developed, tunnels and underground engineering is higher and higher to the use demand of TBM；Therefore, it now needs
It is higher to develop a kind of efficiency of breaking rock, broken rock energy consumption is less, the lower broken rock TBM driving method of mechanical wear and its equipment.

Triangle rock slag piece can be cut；
And use the combined-breaking rock mode of waterpower cutting thread hob of the present invention that can preferably complete a greater degree of broken rock.
The present invention is using the hydraulic-mechanical combined-breaking rock TBM for installing waterpower cutting thread hob additional, by the waterpower cutting part of hobboing cutter
Point (high-pressure water jet) in the front precutting trough of cutterhead rotating direction, waterpower cutting will form the slot of one fixed width and depth (i.e.
Waterpower grooving), waterpower cutting process, which can be formed the rock of face, to be tentatively crushed, on this basis, the double rollings of TBM machinery cutting
Knife cutter body follow-up, rolling cutting waterpower grooving, forms mechanical hobboing cutter track；The follow-up of TBM machinery cutting thread hob makes water
The rock fracture that power grooving is formed, which extends, to be expanded, and the crack between adjacent hobboing cutter crosses；Between adjacent waterpower cutting thread hob
Sillar be cut to triangle rock slag piece and ellipse or plate shape rock slag piece.
Compared with the existing technology, the combined-breaking rock mode that the present invention uses can be improved efficiency of breaking rock, reduce broken rock energy consumption；
Meanwhile being originally that invention waterpower cutting thread hob is cut after broken rock is sequentially first grooving, in time, the two is while work
Make, compared with simple superposition mode, the water mist covering machinery knives part of waterpower cutting hobboing cutter of the present invention is more uniform, and has
Water flow is flowed in cutter interior, and cooling effect is more preferable, equally has positive effect to mechanical wear is reduced.
