A kind of scaling method for closing hydraulic type soil pressure cell, includes the following steps.
Step 1：Pressure assembly assembling is detected with infiltration：Lifting drive is operated, goes up and down lifter plate to setting position；
Then the soil pressure cell demarcated will be needed to put into soil pressure cell slot, and keeps stress face-up；Simultaneously by soil pressure box line from out
It is pierced by the hollow cavity of one contract screw rod of string holes, and keeps the soil pressure box line periphery package being located in contraction screw rod hollow cavity anti-
Glue band；Then pressure probe placement will be surveyed in pressure tap, and survey pressure probe and be located at sustained height with soil pressure cell；It will survey simultaneously
Pressure probe wiring is pierced by from the hollow cavity of two contract screw rod of outlet hole, and visits the survey pressure being located in contraction screw rod hollow cavity
Wrap up adhesive waterproof tape in head wiring periphery；Then two contraction screw rods are tightened with nut, and is filled the water into lifter plate, pressed
The infiltration of component detects.
Step 2, pressure assembly and the assembling of flexible inverted pressure-applying unit and pressure gauge school zero：By the upper of screw thread rubber bag lower end
Connection ring is tightly connected with the lower connection ring being located at the top of lifter plate；Then by pressure gauge school zero, and soil pressure cell is read just
Begin reading.
Step 3, inlet opening is opened, is filled the water into screw thread rubber bag, until water is full, is then closed inlet opening, at this point, again
Soil pressure cell and pressure gauge are read and compared.
Step 4, pressurization calibration：First according to the actual range of soil pressure cell, several pressure calibration points are set；Then pass through
Lifting drive is driven, increase lifter plate height, lifter plate rising can make screw thread rubber bag volume compression, screw thread rubber bag
Internal hydraulic pressure can then increase accordingly, and the compression of screw thread rubber bag is bigger, and the hydraulic pressure in screw thread rubber bag will be higher；When screw thread rubber
When hydraulic pressure in poly-bag is often increased to a pressure calibration point, lifter plate will stop rising, and carry out to soil pressure cell and pressure gauge
Single reading simultaneously compares；Until all pressure calibration points carry out degree and compare completion；Finally according to each pressure calibration point
Comparison result, make composite calibration result judgement.
In the step 2, the upper connection ring of screw thread rubber bag lower end passes through spiral shell with the lower connection ring being located at the top of lifter plate
Line connection, and sealing rubber ring is set in junction.
In the step 4, lifting drive is the handwheel being connected with elevating lever.
The present invention is connect using the above structure and after method, by screw thread rubber bag with lifter plate threaded closure, in screw thread
Constitute enclosure space in rubber bag, then filled the water by the inlet opening of screw thread rubber bag top plate into bag, until filling, it is re-closed into
Water hole；It is corresponding with soil pressure cell to change pressure suffered by soil pressure cell, gauge measurement in slot by the rising of lifter plate
The pressure value of position completes the calibration of soil pressure cell with this.
Pressure transmission is carried out since traditional caliberating device and scaling method use sandy soil medium, will appear during pressure transmission
The phenomenon that stress spread, causes pressurization and the practical pressure of soil pressure cell to differ, and furthermore the planarization in sandy soil medium face is to biography
Whether power uniformly has a significant impact.Compared to traditional sandy soil medium pressure transmission method, the device of the invention and its method use hydraulic pressure
Power transmission, hydraulic pressure in the adjacent area of same horizontal plane its pressure be it is equal, this guarantees the uniformities of soil pressure cell stress
The reliability read with manometer,
In short, the device of the invention and its method are not only fully solved the problem of soil pressure cell unbalance stress, moreover it is possible to make to mark
Determine that result is more accurate, more true is more standardized as a result, simultaneously demarcating the soil pressure cell in laboratory test to test to provide
Change.
