PURPOSE:To facilitate penetration tests under pressure of connecting a pair of pressure penetration tanks via a membrane of a flexible material, perforated plates protecting the same, and ring plates in lieu of said plates, and making possible the counterflow penetration through the various membranes of flexible structure under a pressurized state. CONSTITUTION:A stand 1 is provided with casters 2, 2 for movement. A pair of pressure penetration tanks 3A, 3B are disposed to face each other with a membrane 4 of a material of flexible structure and perforated plates 5, 5 protecting said membrane, which are fastened to one body by bolting of flange parts 6, 6. In order to permit the use of membranes of various thicknesses, many perforated plates and ring plates of different thicknesses are beforehand prepared. Said plates are disposed in arbitrary combinations on both sides of the membrane of the material of flexible structure and are positively sealed with O-rings. Thus the counterflow penetration with various kinds of membranes of different thicknesses under the pressurized state is made possible and the penetration tests under pressure are made easy. |
