Description
Technical field
The present invention relates to attaching/detaching apparatus field in shield body hole, in particular to a kind of TBM shield body rolling slip formula combination walking
Device and method.
Background technique
The driving hole diameter of TBM is 8.13m, a height of 4.065m in hole center, there was only the gap 35mm between anterior shield shell and hole wall,
There was only the gap of 80mm between branch pole and hole wall.In so small driving hole, it is impossible to remove the shield body portion of TBM development machine
Point, it is therefore necessary to shield body is tunneled into hole from hole diameter for 8.13m, sliding walking 20m is walked to the gateway opening type that 14.2m is risen in hole and expanded
In digging a hole.Digging hole, hole bottom is plane, be not able to satisfy anterior shield, branch pole bottom wear-resistant slide plate diameter 8.13m garden expert
It walks to require.
TBM shield body is mainly made of components such as cutterhead, anterior shield, interior external extension shield, branch pole, finger-type shield, girders, anterior shield
The two supporting legs of TBM are equivalent to branch pole.TBM shield body is always about 18m, weighs about 680 tons.680 tons of weight of shield body, by anterior shield
It is undertaken with branch pole, wherein the long 1780mm of anterior shield, undertakes 400 tons of load, be 1118(Kg/ to the average line pressure that sliding rail generates
Cm).The long 3000mm of branch pole undertakes 280 tons of load, is 467(Kg/cm to the average line pressure that sliding rail generates).Anterior shield and branch
Pole is too big to the sliding line pressure generated of fashioned iron, and sliding rail does not undertake.In addition diameter 8.06m is about 18m, weighs 680 tons of shield body
In sliding walking process, it is possible to can be damaged to two side rolls to the equipment equipment such as door machine digged in hole, to existing
The constructing operation personnel of field damage.
It is exactly to reduce anterior shield, support by the anti-sliding walking combined track for sidewindering supporting track, slideway, raceway and forming
For shield to the line pressure in sliding rail unit length, the combination for preventing circular shield body from designing to two side rolls slides running gear.
Summary of the invention
In order to solve the above technical problems, the present invention mentions TBM shield body rolling slip formula combination running gear and method, this device
TBM shield body is solved in the tunnel of narrow space, the difficult construction difficult problem of sliding walking.It can be widely applied to the classes such as water conservancy tunnel
Like engineering construction.
In order to realize above-mentioned technical characteristic, the object of the present invention is achieved like this: the combination of TBM shield body rolling slip formula
Running gear, it includes the bottom plate that tunnel is arranged in and digs section bottom, is fixedly installed with anchor slab by anchor bolt on bottom plate, described
Raceway is fixedly installed with by interior rod piece on anchor slab, is symmetrically fixed with sliding rail on the anchor slab of raceway two sides, in two outside of sliding rail
Anchor slab on be symmetrically fixed with by outer rod piece and anti-sidewinder supporting track；On the sliding rail by roll cooperation support prevented it is more
Root roller；The anterior shield of TBM shield body is supported on raceway, sliding rail and the anti-top for sidewindering supporting track.
Block two sides of the bottom, which are symmetrically fixed with, under the anterior shield of the anterior shield prevents sidewindering support post, described to prevent sidewindering support post
It is matched respectively with the anti-supporting track that sidewinders of corresponding side, and anterior shield is integrally supported.
It is followed successively by external extension shield after the anterior shield, is internally provided with interior flexible shield in external extension shield, stretch shield inside
Tail portion is connected with branch pole, under the branch pole of the branch pole block support on the slide rail, under branch pole the bottom of block not with roller
Contact.
The sliding rail is made of steel plate materials, and the bottom of the sliding rail is supported by H profile steel, and the H profile steel is supported on steel
The top of plate, the two sides of the H profile steel are respectively arranged with outside stiffener plate and inside stiffener plate.
High-grade concrete is all perfused in upper and lower cavity inside the H profile steel.
Described to prevent that sidewindering supporting track is placed on inside channel steel, the anti-supporting track that sidewinders is using I-shaped Steel material system
At the anti-two sides of the bottom for sidewindering supporting track are limited by block, and the anti-bottom for sidewindering supporting track passes through pressing plate
It is fitted in inside channel steel.
Butter is coated on the sliding rail and raceway.
The application method of the combination running gear of TBM shield body rolling slip formula described in any one, it is characterised in that it includes
Following steps:
Step1: section bottom is digged in tunnel and passes through the fixed bottom plate of anchor bolt；
Step2: being fixedly mounted anchor slab by anchor bolt on bottom plate, raceway is fixedly mounted by interior rod piece on anchor slab, in raceway
Symmetrical fixed rack on the anchor slab of two sides is prevented sidewindering supporting rail on the anchor slab in two outside of sliding rail by the way that outer rod piece is symmetrically fixed
Road；
Step3: it is symmetrically fixedly welded in the two sides of the bottom of anterior shield and prevents sidewindering support post；
Step4: the uniformly distributed installation roller on raceway, and the coating butter on raceway and sliding rail；
Step5: the anti-support post that sidewinders is supported on anti-sidewinder on supporting track；
Step6: the bottom of external extension shield, interior flexible shield and branch pole is supported on to the top of raceway and sliding rail；
Step7: shield body is dragged along raceway, sliding rail by traction mechanism and prevents that sidewindering supporting track is slided.
The method have the advantages that:
It is digged in section gateway opening type tunnel in narrow, in hole subdrilling hole, buries rockbolt installation anchor slab, sliding rail and raceway are prevented
The components such as supporting track are sidewindered, are welded and fixed by fashioned iron rod piece with anchor slab.Make bulky, weighs 680 tons, diameter 8.13m's
When cylinder type shield body slides forward walking, between anterior shield and branch pole and combined track, track caused by will not being acted on because of frictional force
Shift deformed damaged；Be symmetrically mounted on 4 groups of block under anterior shield it is anti-sidewinder support post (12) and roller box of walking, one can be supported
Divide anterior shield weight, and can guarantee that shield body slides in walking process forward, not to two side roll unstabilitys.By round steel roller by calculating
Spacing arrange on steel plate raceway, the pressure that anterior shield generates slideway can be reduced.The invention solves TBM shield body in space
In narrow tunnel, the difficult construction difficult problem of sliding walking.It can be widely applied to the construction of the similar engineerings such as water conservancy tunnel.
