Description
Technical field
The present invention relates to a kind of new and effective subway work Suporting structures.
Background technique
It is excavated in construction carrying out subway tunnel using Suporting structure, the traditional method of soil cabin In-pit dumping is in unearthed sleeve
A hole is opened in rear end, and the soil in soil cabin is delivered to unearthed sleeve rear end with screw conveyor bar and the hole by opening up falls to belt
On conveyer, in the transport train soil bucket by belt haulage to about 40 meters of distant places, then tunnel transported by train, and pass through
Vertical handling appliance is finally sent to ground.Due to stratum qualitative diversity, from the muck soil of micro- infiltration, the silty of high viscosity
Clay is to the sand of high infiltration coefficient, some soil properties are because gluing excessively or excessively loosely causing difficulty of being unearthed.Therefore, when necessary can
By Jia Shui plus mud (bentonite) and foam is added to improve the soil body flow in soil cabin and unearthed sleeve in cutterhead, eliminated
Blowout water phenomenon is gushed at unearthed sleeve in sand bed soil.But the problems such as adding the Combination of dilutional hyponatremia or soil and water poor sometimes,
It will cause water spray (or row's sposh) excessive phenomenon at unearthed sleeve, to cause belt feeder to skid and difficulty of transportation, in cabin
Also because sposh fall it is full ground and cleaning of taking a lot of work.The prior art construction when for construction tunneling direction variation centering capacity difference and
It is low to tunnel cutterhead drivage efficiency, to influence entire construction efficiency.

The driving axis connection of dynamic motor, the other end protrude into soil cabin and the end at the end is connected with the cutter axis of cutterhead, are located at cutter axis
The upper paddle slurry between shifting board and cutterhead, the unearthed driving motor being fixed in cabin, one end is fixed in cabin
And be socketed on unearthed driving motor shell, the other end is fixed on unearthed sleeve on shifting board, one end, which is set to, is unearthed in sleeve
And the spiral that shifting board is extend into soil cabin positioned at cutterhead rear is passed through with the driving axis connection of unearthed driving motor, the other end and is gone out
Native bar is each attached on the inside of shield shell and is located at separate one end equipped with shifting board in cabin, along shield shell inner circumferential
It is uniformly distributed, the hydraulic jack of four longitudinal directions of mandril outwardly；The unearthed sleeve connects at unearthed driving motor
It is connected with dregs conveyance conduit, the dregs conveyance conduit is connected with the compression of air compressor being equipped with unearthed sleeve connectivity part
Air accesses valve, is equipped with a lubrication every 3~4 meters since it is with unearthed sleeve connectivity part on the dregs conveyance conduit and is situated between
Matter entrance；The oil circuit of four hydraulic jacks uses two opposite hydraulic jacks to connect as one group and two groups of jack
It organizes mode in parallel again to connect, the cutterhead is spoke-type or panel type.
Preferably, the diameter of the dregs conveyance conduit is 30~60 centimetres.
Compared with prior art, the invention has the following advantages:
The configuration of the present invention is simple, design is scientific and reasonable, easy to use；By by belt feeder in the prior art be unearthed mode
Be improved to using dregs conveyance conduit carry out it is unearthed, and on dregs conveyance conduit every 3~4 meters be equipped with a lubricant medium enter
Mouth keeps the present invention more smooth when construction is unearthed, belt when efficiently avoiding carrying out unearthed using the unearthed mode of belt feeder
Machine, which easily skids, causes the soil being unearthed on difficult and belt feeder to be easy to fall the situation for increasing disposal costs in cabin；Four
The oil circuit of a hydraulic jack selects opposite two hydraulic jacks to connect for one group and two groups of jack groups company in parallel again
Connect mode, so that two series connection jack strokes of diagonal line (i.e. with respect to) are consistent, can be in shield device tunneling direction
When variation, by adjusting the extended position of end cap, achieve the purpose that rectify a deviation in tunneling process, the cutterhead design of driving is at spoke
Type or panel type, so greatly improve construction efficiency.
