Control is come what is realized, so the liquid level in muddy water storehouse is ceaselessly to change, this brings jolt to mud and water balance, influences excavation face
Stablize.When actually shield machine tunnels, the pressure of excavation face is in the nonequilibrium condition under certain process stage, when the height of liquid level
When degree variation, the pressure of gas is definite value, causes the mud pressure for acting on bottom to generate variation, causes excavation face pressure wave
It is dynamic, the stabilization of excavation face is influenced, certain ground settlement is caused.Although having some about the relevant control of shield slurry at present
System and pipe-line system, CN102330557A, CN201568058U, CN201354640Y as disclosed in Patent Office of the People's Republic of China, still
Ground settlement is not controlled to control slurry injection about by controlling air cushion storehouse.
Invention content
The present invention solves above-mentioned technical problem and provides a kind of gas cushion type mud water shield machine muddy water storehouse mud compensation system, has
The fluctuation that the system balancing that effect ground solves mud system by the flow control into stock pump and slurry pump to realize generates, reduces because of mud
The stabilization for the excavation face that system fluctuation influences is starched, reducing shield-tunneling construction influences.
The present invention solves the technical solution that technical problem uses：
A kind of gas cushion type mud water shield machine muddy water storehouse mud compensation system, it includes being arranged behind shield machine muddy water storehouse before endplate
The air cushion storehouse at end, air cushion the top of the warehouse are equipped with liquid level sensor, and air cushion storehouse gas pressure monitoring device is arranged in air cushion storehouse, described
Liquid level sensor and air cushion storehouse gas pressure monitoring device are all connected with intelligent controller, and it is empty that compression is separately connected on intelligent controller
Gas regulating system and mud fluid reservoir, mud fluid reservoir outlet connects muddy water storehouse by the first hydraulic control ball valve, described
Mud fluid reservoir entrance is connected by the second hydraulic control ball valve into slurry system, is set between the mud fluid reservoir and intelligent controller
There is a pressure sensor, the liquid level sensor and air cushion storehouse gas pressure monitoring device in air cushion storehouse are by electric signal transmission to intelligent control
Device, while pressure signal is also transferred to intelligent controller by the pressure sensor on mud fluid reservoir,；Intelligent controller will control
Signal is sent to compressed air conditioning system, adjusts the pressure in mud fluid reservoir, and the mud compensation in mud fluid reservoir is arrived
In muddy water storehouse, to reduce mud system by the flow control into stock pump and slurry pump come the fluctuation for the system balancing generation realized.
Check valve is set on the pipeline of above-mentioned mud fluid reservoir import front end, prevents mud from flowing back.
Above-mentioned air cushion storehouse gas pressure monitoring device is baroceptor.
Beneficial effects of the present invention：
1, the system balancing that the present invention efficiently solves mud system by the flow control into stock pump and slurry pump to realize generates
Fluctuation, reduce because mud system influence of fluctuations excavation face stabilization, reduce shield-tunneling construction influence；
2, the liquid level sensor and gas pressure sensor in the application air cushion storehouse by electric signal transmission to intelligent controller, while mud
Pressure signal is also transferred to intelligent controller by the pressure sensor on slurry fluid reservoir；Intelligent controller is sent control signals to
Compressed air conditioning system adjusts the pressure in mud fluid reservoir, and the mud in mud fluid reservoir is compensated into muddy water storehouse, with
The fluctuation that the system balancing for reducing mud system by the flow control into stock pump and slurry pump to realize generates.
