The all other embodiment obtained, belong to the scope of the utility model protection.
In description of the present utility model, it is to be understood that term " perforate ", " on ", " under ", " thickness ", " top ",
" in ", " length ", " interior ", indicating position or the position relationship such as " surrounding ", be for only for ease of description the utility model and simplification
Description, rather than the component or element of instruction or hint meaning must have specific orientation, with specific azimuth configuration and behaviour
Make, therefore it is not intended that to limitation of the present utility model.
A kind of push-bench stirs spoil hopper pressure air cushion adjusting device, including housing 14, as shown in figure 1, being provided with housing 14
Spoil hopper plate 6 and pressure deck board 9, the downside of pressure deck board 9 are provided with mud discharging mouth 8, and the upside of pressure deck board 9 is provided with air inlet pipe 12 and blast pipe
13；The downside of spoil hopper plate 6 is provided with spoil hopper plate opening 5, and the side of spoil hopper plate opening 5 is provided with sieve aperture Turbogrid plates 3, sieve aperture Turbogrid plates 3 one
End is fixed on spoil hopper plate 6, and the other end is fixed on the inner side of housing 14, is formed between sieve aperture Turbogrid plates 3 and spoil hopper plate opening 5 into mud
Passage 4；One end of housing 14 is provided with more stratum cutterheads 1, and more stratum cutterheads 1 are used for the broken and cutting of rock or the soil body.
Spoil hopper plate 6, more stratum cutterheads 1 and housing 14 form stirring spoil hopper 2, spoil hopper plate 6, pressure deck board 9 and the shape of housing 14
Into pressure chamber 7, the pressure in pressure chamber 7 is measured by pressure sensor；Cutter plate driver motor 10, knife are provided with housing 14
Rotating shaft 16 on disk-drive motor 10 passes through pressure deck board 9 and spoil hopper plate 6, and rotating shaft 16 is provided with agitating shaft 15, agitating shaft 15
In in stirring spoil hopper 2.
During work, entered by more attrition crushings of stratum cutterhead 1 or the rock or the soil body of cutting in stirring spoil hopper 2, to stirring
Work mud is injected in mud 2 and water is stirred mixing, is screened, filtered out by sieve aperture Turbogrid plates 3 after being stirred
Meet the suspended mud that the rock fragment of size and improvement dregs mud are mixed to form, suspended mud passes through by entering mud passage 4
Spoil hopper plate opening 5 enters pressure chamber 7, and the compressed air of the top of suspended mud and pressure chamber 7 in pressure chamber 7 is put down in air mud
The interaction of weighing apparatus face 11 forms air cushion, controls the pressure of more faces of stratum cutterhead 1 by adjusting the pressure of air cushion, and air cushion
Pressure be controlled by the compressed air supply and discharge equipment connected with air inlet pipe 12, blast pipe 13.
In unstable stratum such as flour sand, gravel soil property, the pressure of stirring spoil hopper 2 can be controlled by air cushion, can be more
Safely, the earth pressure balance of front face is accurately controlled, while to can compensate for the mud as caused by emergency situations quick for air cushion
Pressure drop caused by loss and water burst phenomenon, reduce the risk that emergency case is brought to construction.
In the stable for example fully hard rock in stratum or closely knit clay, the air in pressure chamber 7 is discharged by 13 blast pipes
Afterwards, 12 air inlet pipe, 13 blast pipes are blocked, is converted into common slurry-water balance type push-bench.
The spoil hopper in single cabin is distinguished into separate two sections by spoil hopper plate 6 and pressure deck board 9, leading portion is full of Pressure Slurry
Stirring spoil hopper 2, back segment is pressure chamber 7.The first half of pressure chamber 7 is compressed air area, is formed and pressed in air mud balanced surface 11
Contracting mattress, lower half are mud area, the soil of slurry cabin, rock etc. mixed with water under high pressure after by sieve aperture Turbogrid plates 3 and spoil hopper
Plate opening 5 enters pressure chamber 7 in the form of suspended mud.In pressure chamber 7, gas pressure is acted on mud.
Because the gas in pressure chamber 7 is identical with the pressure of liquid, therefore only need to adjust air pressure, it is possible to flat
Weigh corresponding soil pressure on more faces of stratum cutterhead 1；When push-bench tunnels, loss and jacking speed due to mud
Change, the mud amount of disengaging will disequilibrium, the pressure stirred in spoil hopper 2 changes, and air mud balanced surface 11 is just
Fluctuation up and down can be produced.According to the change of liquid level, the rotating speed of supply and discharge slush pump is controlled, adjusted by sensor, can be adjusted at any time
Pressure in section stirring spoil hopper 2, realize the Pressure behaviour balance of stirring spoil hopper 2；When air mud balanced surface 11 reaches highest pole
During extreme position, it can be automatically stopped for dredge pump and stop jacking, when air mud balanced surface 11 reaches lowest limit position
When, sludge pump can be automatically stopped.
Pressure in the utility model in pressure chamber can be continued to monitor, than traditional single storehouse pressure-measuring system more
Accurately；Air cushion can compensate for the mud as caused by emergency situations quickly loss and pressure drop caused by water burst phenomenon, non-homogeneous
Under geological conditions, pressure and volume fluctuation even if very little can also be precisely controlled, thus can to the protuberance of earth's surface and
More preferable control is made in sedimentation, and the protuberance of earth's surface and sedimentation should avoid, especially in the case of earthing very little.
Air pressure, pressure regulation cabin liquid level, the mud pressure data transfer to air adjustment collected by sensor
Equipment, by balancing pressure in caving ground and a variety of mixing stratum to automatically controlling for air pressure to buffer, compensate
Fluctuation, prevent that the quick-fried and dregs of slurries spray gushes cabin.
