A pressurized water inlet 9 is provided in the upper compartment 2, a pressurized water inlet 10 is provided in the middle compartment 3 (laboratory), and a pressurized water inlet 11 is provided in the lower compartment 4. The middle compartment 3 (laboratory) is provided with a laboratory equipment mounting port 12. An experiment is performed by putting earth and sand 5 into the middle compartment 3 (laboratory). At this time, when the earth and sand 5 is pressurized, it is desirable to arrange the pressing plates 6 above and below the earth and sand in order to uniformly transmit the pressure to the earth and sand 5.

When the hole of the perforated support plate 8 presses the lower compartment 4, the pressure medium moves to the diaphragm 7 through the hole of the perforated support plate 8, deforms the diaphragm 7, and effectively sediments 5 from the lower portion. It serves to pressurize. Therefore, it is not always necessary to use the perforated supporting plate 8, and for example, a load supporting table 8a, a gravel 8b having a relatively large particle size, or the like may be used.
