Description
Technical field
The present invention relates to the slag gathering hoppers of double mode TBM a kind of, are mainly used for double mode TBM and switch belt in tunneling process
Isolation when conveyer and screw conveyor.
Background technique
Currently, development machine is widely used in the excavation site of the tunnel structures such as subway tunnel and mountain tunnel, development machine
It is divided into according to the difference of the geology of excavation: earth pressure balance development machine (referred to as: EPB) and tunneling boring hard rock mole (abbreviation:
TBM), earth pressure balance development machine is for tunneling weak soil or sand geology, and tunneling boring hard rock mole is for tunneling hard rock geology.
But current development machine only can be suitably used for that ambient enviroment is of less demanding and the single area of geological conditions, however in driving same
During tunnel, it is easy the different stratum of driving, and development machine is not able to satisfy the construction requirement of different geological conditions at present, leads
Cause separate unit development machine use scope relatively narrow.
The design of bimodulus TBM is not single excavation project especially suitable for geology, which can face firmly along tunnel
Rock stratum and weak soil or sandy soils, because bimodulus TBM can be carried out in die sinking (belt conveyor) and die closing (screw conveyor)
Switching, meets being required for hard rock TBM and EPB type.
Bimodulus TBM is a kind of extremely complex TBM, and in all engineering projects, the alternating of rock and clay is many institute's weeks
Know with it is predetermined, allow constructing tunnel personnel to shift to an earlier date and the timely all conversion operations arranged between hard rock TBM and EPB.
There are two types of conventional conversion modes, the first is reserved hard rock center slag gathering hopper and the bottom EPB slag notch simultaneously, in driving hard rock
When matter, belt conveyor is installed, cooperation center slag gathering hopper is slagged tap；When tunneling weak soil or sand geology, belt conveyor is dismantled,
In bottom, slag notch inserts screw conveyor.The translative mode is inconvenient, time-consuming and laborious.Second is the reserved hard rock that misplaces simultaneously
Center slag gathering hopper and the bottom EPB slag notch install belt conveyor and screw conveyor simultaneously in shield body, in driving hard rock
When matter, opens belt conveyor and slag tap；When tunneling weak soil or sand geology, belt conveyor is closed, opens spiral transferring
Machine is sent to slag tap, which leads to insufficient space in shield body, and it is inconvenient for operation, it is unable to satisfy the construction of minor diameter TBM
It is required that.
Summary of the invention
It is an object of the invention to provide the slag gathering hopper of double mode TBM a kind of, to solve of the existing technology to lead to shield
Internal insufficient space, inconvenient for operation, the problem of being unable to satisfy the construction requirement of minor diameter TBM.
The technical scheme is that a kind of slag gathering hopper of double mode TBM, which is characterized in that including inner cylinder, inner cylinder end
Plate, inner cylinder sealing, outer cylinder sealing, outer cylinder, sliding block, hopper and limit plate, inner cylinder are mounted in outer cylinder with being slidably matched, the outer cylinder
It is mounted in main driving；The front end of the inner cylinder be equipped with interior tube end-plate, the rear end of the inner cylinder be mounted on it is hydraulic in the outer cylinder
The piston rod of cylinder connects；It is equipped with feed inlet in the upper front end of the inner cylinder, hopper is housed on the inner cylinder in the feed inlet；Inside
Behind tube end-plate and outer cylinder front end is respectively provided with mutual corresponding inner cylinder sealing and outer cylinder sealing.
The lower part of the inner cylinder is slidably connected on the sliding rail of outer cylinder inside bottom by sliding block.
The flange flange connecting for the entrance with conveyer is equipped in the rear end of the inner cylinder.
Limit plate is equipped with before the interior tube end-plate.
The invention has the advantages that can will excavate room (the subsequent entire chamber of cutterhead) and conveyer installing port (flange) every
From in order to the installation of screw conveyor, and continuing to tunnel under EPB mode；Being equipped between interior tube end-plate and outer cylinder can hold
By the sealing of 5bar pressure, muddy water is avoided to enter.Conveyer installing port is connected by the entrance of flange and conveyer, is simplified more
Change operation；The inner cylinder of slag gathering hopper can be sealed by the slide construction of Driven by Hydraulic Cylinder and be excavated room, be switched efficient and convenient.It can basis
Cutterhead needs to adjust the stroke size of inner cylinder back-and-forth motion, to ensure that feed inlet is met the requirements.Compact-sized, installation space is small,
Switching is quick, easy to operate, laborsaving, safe.
