Embodiment
In order that those skilled in the art more fully understand the technical scheme in the application, it is real below in conjunction with the application
The accompanying drawing in example is applied, the technical scheme in the embodiment of the present application is clearly and completely described, it is clear that described implementation
Example only some embodiments of the present application, rather than whole embodiments.It is common based on the embodiment in the application, this area
The every other embodiment that technical staff is obtained under the premise of creative work is not made, it should all belong to the application protection
Scope.
Firstly the need of explanation, the upper and lower part of the cylinder of screw machine 1 described herein is for the side of description
Just, centered on helical axis, the cylinder of screw machine 1 is " bottom " close to the side on ground, with the side " top " away from ground,
This programme is not limited.
The cutterhead 15 of shield machine cuts the soil body, is tunneled.Balancing earth-pressure shielding machine discharges dregs using screw machine 1, can
To carry the solid particle of greater particle size, it is relatively inexpensive to convey the mode of dregs, but it cannot be used for that hydraulic pressure is larger, surface subsidence
Control exigent occasion；Slurry shield machine takes slag and long-distance transportation slag charge using hydraulic fill pipeline, excavate face stability compared with
It is good, there is wide geological adaptability, but it needs to configure mud piece-rate system and modulates mud, and slurry shield machine equipment
Cost is higher, and slurry shield machine construction cost is higher, and substantial amounts of solid slag is contained in the mud of plasma discharge pipeline transportation, existing
Settling mode is that quarrying case is set on slurry shield machine, and the solid in hydraulic fill pipeline is precipitated, filtered, although such energy
Enough destructivenesses for alleviating solid to a certain degree, but the general finite capacity of case of quarrying, and grid is easily blocked, it is necessary to periodically beat in case
Exploitation stone case empties and handled solid slag, causes construction to interrupt or even shut down, significantly impacts efficiency of construction, adds construction
Cost.
As shown in Figures 1 to 4, a kind of decompression type shield machine, including shield main frame, screw machine step by step that the present embodiment provides
1st, main pulp-inlet pipe road 2 and main plasma discharge pipeline 3, the screw machine 1, the main pulp-inlet pipe road 2 and the main plasma discharge pipeline 3 are located at institute
Inside the shield for stating shield main frame, the main pulp-inlet pipe road 2 native storehouse 4 anterior with the shield main frame connects, the screw machine 1
Entrance connects with the native storehouse 4, it is characterised in that the main plasma discharge pipeline 3 connects with the cylinder of screw machine 1, the main row
Slurry pipeline 3 is provided with the first valve 5 and the first slush pump 6, and first slush pump 6 is used for the mud in the screw machine 1
Discharged through the main plasma discharge pipeline 3, the afterbody of the screw machine 1, which is provided with, unloads cinder notch 7.
The decompression type shield machine step by step that the present embodiment provides, has slurry balance shield pattern and soil balance shield bimodulus
Formula, possesses the advantages of two kinds of shield patterns.Under slurry shield boring mode, carry in soil cabin the mud of a large amount of solid particles from
The entrance of screw machine 1 enters screw machine 1, and mud is good in the cylinder internal mobility of screw machine 1, so as to which it is compared with solid especially bulky grain block
Shape solid is easier to convey, due to speed difference between mud and solid slag be present, in the cylinder of screw machine 1, and mud and solid
Slag charge can axially be isolated gradually along screw machine 1, and solid slag is axially spaced along screw machine 1 in helical blade 101
Area's deposit buildup, mud and solid slag good separating effect, the amount into mud in main discharge pipe road 3 is reduced, and can be effective
The content of solid slag in mud in main plasma discharge pipeline 3 is reduced, so as to reduce the installed power of pipeline mud, is reduced
The loss of equipment and operating cost, helical axis rotational conveyance of the slag charge being deposited in screw machine 1 through screw machine 1 to unloading cinder notch 7,
And screw machine 1 is discharged by unloading cinder notch 7, the shield machine can successively discharge slag charge, be not required to interrupt driving in tapping process, greatly
Equipment operating efficiency is improved, production efficiency is high.Under soil shield pattern, only the first valve 5 need to be closed, you can using spiral
Machine 1 discharges dregs.The handover operation of two kinds of shield patterns of the shield machine is simple, can two kinds of shield patterns of free switching, without
Dismount any part.

The porch of screw machine 1 is provided with the 7th valve 16.During work, the 7th valve 16 is opened, carries a large amount of solid particles
Mud enters screw machine 1 from native storehouse 4 through the entrance of screw machine 1, and in the cylinder of screw machine 1, solid slag is along screw machine 1 axially in spiral shell
The deposit buildup of section gap area 102 of vane piece 101, because section gap area 102 accumulates, the solid of densification is made with " obstruction "
With considerably increasing the resistance that mud passes through, cylinder Inner Front End, which is progressively accumulated, to form that one section of resistance is big, has certain water penetration
" embolism solid " 20.The mud with larger pressure is after certain length and the embolism solid 20 of quantity in soil cabin, in mud
Under the swabbing action of pump, its pressure is more and more lower, and is finally down to normal pressure unloading cinder notch 7.So, it is achieved that from high-pressure slurry
To the decompression step by step of low pressure mud, while bulky grain solid is also synchronously completed and has been separated with the continuous of mud.Cinder notch 7 is unloaded in normal pressure
Lower progress slag charge discharge, it is big compared with external pressure so as to which the interior pressure at cinder notch 7 of screw machine 1 will not be unloaded, and cause slag charge
Ejected from cinder notch 7 is unloaded.The solid slag that mud after precipitation contains is less, and main plasma discharge pipeline is discharged into by the first slush pump 6
3；Solid slag in screw machine 1 moves in the case where helical axis rotates deslagging and mud takes slag double action to the afterbody of screw machine 1,
And discharge screw machine 1 by unloading cinder notch 7.Unload and gate 17 is provided with cinder notch 7, according to bed drain purge and the inner barrel solid pressure of screw machine 1
The needs of tight degree, the big I for unloading cinder notch 7 are adjusted flexibly.
Specifically, blade 101 has many places section gap along helical axis is axially arranged, the helical blade 101 in section gap area
Disconnecting, break distance is at least 0.5 times of pitch, and the interval between each segmentation can specifically determine according to actual conditions, but not
Preferably more than 2 times pitch.The section gap area 102 of helical blade 101 is advantageous to the deposit buildup of solid slag, in helical blade 101
Section gap area in formed with " obstruction " act on " embolism solid " 20, can both realize and depressurize step by step, and be advantageous to mud again
Slurry and the separation of solid material residue, so that the effect that solids content is reduced in mud is more preferable.The import of main plasma discharge pipeline 3 should not be set
Put in the section gap area 102 of helical blade 101, but be opened in the position that helical blade 101 is continuously arranged.Using soil pressure mould
When formula carries out long distance tunnel driving, helical axis can also be changed the outfit into the spiral shell that helical blade 101 continuously arranges (no section gap)
Spin axis, the slag discharge efficiency under soil pressure pattern can be improved.
