Description
Technical field
The invention belongs to the Shield-type machinery field of constructing tunnel, more particularly, to a kind of soil pressure case quick-replaceable
Device.
Background technology
It is heavy in order to control earth's surface during using balancing earth-pressure shielding machine or slurry balance shield machine tunneling
It dropping, the pressure in shield machine soil storehouse must be detected reliably, and generally use soil pressure case detects the pressure of Tu Cang immediately,
The pressure that PLC program is acquired according to soil pressure case controls the parameters such as the fltting speed of shield machine, the unearthed amount of screw machine, because
This, the parameter and drivage efficiency that pressure in native storehouse tunnels shield machine influence very big.
In construction of underground tunnel, the medium for the soil pressure case contact installed in native storehouse is generally muddy water, cobble, clay
Deng the very easy damage of soil pressure case.The common soil pressure case of shield machine is mostly fixed soil pressure case at present, a small number of
Using exchangeable soil pressure case.Wherein, fixed soil pressure case (structure is shown in attached drawing 1) can not be with pressure in native storehouse
It is replaced, because shield machine, in driving with pressure, maximum pressure can reach 5bar in native storehouse, if replacement soil pressure with pressure passes
Sensor, muddy water or dregs can gush out of soil pressure case mounting hole into inside shield body;Exchangeable soil pressure case is then deposited
In mounting structure complexity, replaces disadvantages, the structures of exchangeable soil pressure case such as cumbersome and safety is low and see attached drawing 2, use
Ball-valve structure is sealed, and sealing effect is poor, and when being dregs or cobble inside native storehouse, ball valve is easy to block and can not close,
Using screw rod manually with changing, troublesome in poeration, inefficiency and safety is low.
Invention content
In view of this, the invention is directed to a kind of soil pressure case quick replacement device, to solve existing soil pressure
