Description
Technical field
The invention belongs to underground engineering Rock And Soil drilling, cutting and underground engineerings to prevent and reduce natural disasters technical field, especially relate to
And a kind of vertical combined type multidimensional of flank-for soft or hard stratum freezes drilling method.
Background technique
Soft or hard stratum complicated geology is changeable, is the stratum that underground engineering construction frequently encounters in the process, and cause geology
The main hazard source of disaster, especially rich water hard-soft heterogeneous ground, easily initiation ground settlement, pile position deviation, surface buildings
Collapse, shield tunnel open a position tool changing face collapse, seabed rich water tunnel rupture etc. accidents, this is because in soft or hard stratum crossing construction
Different from single soft formation and hard formation, since the stiffness difference of soft formation and hard formation is big, drilling speed on the stratum,
And hard-soft heterogeneous ground is unequal to the reaction force of drilling cutter, so that it is single to cause soft or hard stratum drilling to be different from
Soft formation and hard formation, cause the drilling power ratio of drilling construction surface more difficult to control in single soft formation and hard formation.
The existing drilling apparatus for the construction of soft or hard stratum mainly has the shield cutter of super-large diameter, shield scraper, shield
Drill bit etc. is scraped in structure rounding machine cutter, PDC drill bit, physical prospecting punching, and the existing cutter device for the construction of soft or hard stratum is mainly embedded rock pile
Pneumatic control type cutting, but the shields class drilling apparatus such as the shield cutter of super-large diameter, shield scraper, shield machine cutter figure is huge
Greatly, involve great expense, PDC drill bit, physical prospecting punching scrape the small engineering investigations class drilling apparatus drilling diameter such as drill bit, wing distribution angle and
Cutting tooth distribution setting is unreasonable, and cut surface drilling power cannot be with formation variation when embedded rock pile Pneumatic control type cuts soft or hard stratum
And real-time change, it is functional to be improved.Therefore, existing soft or hard stratum construction pore-creating device, mainly single pierces dress
It sets and cutter device, lacks while having both drilling, cutting function in the composite drilling cutting apparatus of one.
A kind of super-large-diameter shield cutter disc system for hard-soft heterogeneous ground of Chinese patent CN106907158A, including it is big
Type cutterhead, medium-sized cutterhead, small-sized cutterhead, it is spoke, panel, hobboing cutter, cutter, dual-pilot cutter, center cutter, stirring rod, retarder, hydraulic
Motor, power transmission, shield and screw conveyor device, but it is multilayer cutterhead spatial intersecting that the cutter disc system, which lays mode,
Distribution, involves great expense, when cutterhead, which meets soft or hard stratum, carries out drilling construction, due to being limited to shield front end cutterhead as whole knot
Structure is only capable of driving shield to pierce soft or hard area by controlling all kinds of cutterheads, it is difficult to various regions when effectively controlling the construction of soft or hard Different Strata
The drilling power of the corresponding cut surface of layer, while the hard formation in soft or hard stratum can not be cut, soft or hard stratum can not be carried out cold
The construction of jelly method.
Chinese patent CN206495679U one kind shield scraper used in hard-soft heterogeneous ground, including cutter hub, in knife
The upper surface of body a side is equipped with cutting edge, and mounting hole is equipped on the inclined-plane on cutter hub top, closes at the back of cutter hub equipped with hard
Gold is equipped with wear-resistant alloy layer at the cutting edge position of cutter hub, but the shield scraper is mainly to enhance its resisting in poor strata
Impact property, and at high cost, the precision of main structure when not can guarantee the construction of soft or hard stratum, it is impossible to be used in the soft or hard stratum of drilling
In Rock And Soil.
A kind of shield machine cutter suitable for hard-soft heterogeneous ground of Chinese patent CN204552753U, including it is mounted on cutterhead
On multiple knife combinations, knife combination includes hobboing cutter and bite, and the axle portion of hobboing cutter is equipped with sensor, and hobboing cutter rear portion is fixed
It is mounted on cutterhead, bite rear portion is mounted on cutterhead by the pedestal with hydraulic telescopic device, and pedestal can be along shield
Arbor moves forwards, backwards, but the shield machine cutter is overall structure due to being limited to shield front end cutterhead, is only capable of passing through control
Hobboing cutter and bite pierce Rock And Soil, cannot precisely adjust all kinds of Different Stratas such as soft formation, hard formation, soft or hard mutual stratum and apply
Working hour shield cutter pierces the power that pierces in face, and at high cost, can not cut the hard formation in soft or hard stratum.
A kind of five wing PDC drill bits suitable for soft or hard staggeredly stratum of Chinese patent CN203891774U, including drill body
And five wings of drill body bizet are convexly equipped in, several grooves for sundries to be discharged are formed between wing, the drill bit passes through
It adjusts the distribution angle of wing and the main cutting tooth on wing is distributed to drill, when meeting soft or hard stratum, the master on wing is cut
The drilling force of main cutting tooth cannot be adjusted with the variation of landing surface by cutting tooth, and the stress that not can guarantee main structure in soft or hard stratum is equal
Even property, it is impossible to be used in the drilling and cutting on soft or hard stratum in Rock And Soil.
A kind of Pneumatic control type for embedded rock pile hard-soft heterogeneous ground of Chinese patent CN106223855A cuts rock device, packet
It includes and cuts rock casing, taper cutting tool system, tooth form cutting tool system, vibration sensing system, air pressure sensing system, air pressure capsule
System, high-pressure water pipe, multipath connector, isolation spring, drilling rod, gas pressure regulator, vibrating controller, high-pressure hydraulic pump, cable,
Strong Adhesive, pneumatic flow controller, air pressure consolidate bolt, Rubber shock-absorbing pad, vibration isolation fastening bolt, maintenance pin.The dress
Stress condition when cutting rock primarily directed to soft or hard rock is set, constant pressure is kept to empty soft rock is bored, the hard rock that do not cut all is applied
It is with air pressure capable of being increased, but the device can not solve to meet the cutting force of the Different Stratas cut surfaces such as soft formation, hard formation, soft-hard combining stratum
Adjustment problem in real time, while the quick discharge of chip when the cutting of soft or hard stratum can not be also solved, hard formation cannot be especially cut,
It cannot keep the uniform force of cutter device.
