Description
Technical field
The present invention relates to shield tunnel construction technology fields, and in particular to a kind of full-sleeve full-rotation drill sleeve and shield
Cutterhead front obstacle sweep-out method.
Background technique
During shield tunnel construction, since the complexity of engineering geological condition and prospecting are not thorough enough, shield machine exists
The unknown hard objects such as boulder, erratic boulder or the cable and optical cable left may be encountered in work progress because of front, lead to shield driving
Difficulty, can not drilling depth, so that shield machine is got into a difficult position.Currently, when encountering such situation during shield-tunneling construction, often first to front
Stratum carries out consolidation process, then normal pressure is taken to open a position clear shield cutter front obstacle type, and vertical shaft is used in front of cutterhead
Or the taking-up that opens a position, abolish barrier.However, both processing methods have the defects that it is certain: it is with pressure in shield machine to open a position
When, pressure maintaining is difficult in soil pressure cabin, requires the technical level of staff in cabin high；Level of ground water is higher, and shield tunneling face is lost
Steady and worker safety's risk is higher；The consolidation process expense of two methods is higher, and the construction period is long, leverages
Engineering construction progress.In addition, existing full-rotating drill sleeve does not have the item that opens a position in sleeve wall since sleeve wall thickness is larger
Part is not suitable for removing the barrier outside sleeve.
Summary of the invention
It is an object of the present invention in view of the deficiencies of the prior art, provide a kind of safe and simple full-sleeve full-rotation brill
Machine and shield cutter front obstacle sweep-out method.
The technical solution adopted by the present invention is that: a kind of full-sleeve full-rotation drill sleeve, including sleeve, the upper end of sleeve with
Slewing drilling machine is connected, and slewing drilling machine provides rotary power for sleeve；The lower end of sleeve is fixed with hard alloy serrated knife.By above-mentioned side
Case, the sleeve are welded by single-unit sleeve is successively from beginning to end, and the wall thickness of sleeve is 20 ~ 30mm.
According to the above scheme, multiple holes for hoist are provided at circumferentially spaced at the top of sleeve.
The present invention additionally uses a kind of cutter head of shield machine front obstacle sweep-out method, comprising the following steps:
Step 1: closing each mechanism of shield machine, stop driving, and the soil pressure in shield machine soil pressure cabin kept to stablize,
Bentonite is injected into soil pressure cabin；
Step 2: providing as described above for the Novel sleeve of full-sleeve full-rotation drill and slewing drilling machine etc.；
Step 3: opening up geological drilling hole from adjacent ground surface above the shield cutter of shield machine, shield is determined with bit freezing method
Remove obstacles construction infection range and the buried depth of cutterhead front obstacle；
Step 4: opening up dewatering well within the scope of construction infection of removing obstacles, bailing test is carried out, and monitor pump-out, observed
WATER LEVEL CHANGES；
Step 5: determining the sleeve portion of full-sleeve full-rotation drill and tunneling to underground, cover sleeve to greatest extent
Barrier position；Full-sleeve full-rotation drill is drilled into shield tunnel bottom or less at least 2m；
Step 6: the soil body and barrier in cleaning sleeve；
Step 7: sending operator to sleeve bottom, and fresh air, real-time monitoring set are persistently conveyed to sleeve bottom
Oxygen content and other poison gas contents in cylinder；
Step 8: selected towards shield cutter direction according to sleeve portion and buried depth, cutting-sleeve is open on sleeve, people
Work or mechanical means excavate the soil body outside sleeve openings, and clear up the barrier between sleeve and shield cutter；
Step 9: backfilling sand in sleeve, and gradually pull out sleeve in backfilling process after the completion of barrier cleaning
It rises；
Step 10: being ready for next stage cleaning.
According to the above scheme, in step 3, the construction infection of removing obstacles of shield cutter front obstacle is determined using bit freezing method
Range and buried depth；The bit freezing method is i.e. along shield tunnel axis to the direction of shield cutter and from two side of shield cutter to shield
Structure tunnel axis direction opens up geological drilling hole, and at shield cutter, the spacing in geological drilling hole is smaller.
According to the above scheme, in step 3, geological drilling hole is opened up using geological drilling rig, the depth in geological drilling hole should surpass
Cross shield tunnel bottom or less 2m；When drilling, the drill bit of geological drilling rig is not less than 500mm at a distance from shield cutter.
According to the above scheme, in step 5, after full-sleeve full-rotation drill is drilled into shield tunnel bottom or less at least 2m, lead to
It crosses unlatching dewatering well to draw water, makes underground bearing water potential drop to shield tunnel bottom or less.
According to the above scheme, in step 8, sleeve openings are not more than 0.5m2, whether observe after cutting has Sand existing
As: if so, continuing the lowering of watertable that draws water from dewatering well；If nothing, excavated outside sleeve openings using manually or mechanically means
The soil body, and clear up the barrier between sleeve and shield cutter.
According to the above scheme, in step 3, in coverage of removing obstacles namely shield cutter in front of and 1 ~ 2 times of two sides tunnel
Setting surface subsidence monitoring point in interval is supervised in barrier reset procedure with the frequency not less than 12h/ times within the scope of road buried depth
Survey the ground settlement deformation removed obstacles in coverage.
It according to the above scheme,, can be first with the impact drill addi-tional crusher soil body if the soil body or barrier are harder in step 5
And barrier, then the soil body and barrier are removed with hydraulic grab.
The invention has the benefit that
1) present invention can quickly determine position and the buried depth of barrier, using full circle swinging full set cylinder drilling machine can fast drilling,
After below drilling to shield tunnel bottom plate, pressure water head is circumferentially descended using dewatering well reduction, avoids piping quicksand risk, it is ensured that
Can be in sleeve upper opening, the barrier quickly removing using hydraulic grab the soil body in sleeve and expose；
2) present invention is used using the barrier in front of full-sleeve full-rotation drill auxiliary cleaning cutter head of shield machine, casing
Q235B steel roll, and can preset gate-type opening in portion under a bushing, or carry out cutting openings using oxygen-acetylene, into
And the barrier outside sleeve in front of shield cutter is cleared up, and end is welded with hard alloy serrated knife, it is applicable in all kinds of stratum
Driving and the hard barrier of crushing kinds；Compared with existing use drilling machine removing obstacles, it is not necessarily to consolidation process after boring under sleeve,
On the one hand construction cost is reduced, also improves construction speed；On the other hand, staff's notch operation in sleeve, is also protected
The safety of operator is demonstrate,proved；
3) safe and efficient, simple and quick construction and economy of the invention, can thoroughly remove cutterhead front obstacle, be work
Journey, which is met barrier in front of shield cutter in practice and can not be tunneled forward, provides a kind of easy, efficiently, quick, economic processing side
Method has important practical engineering value.
