Title:
地山の改良評価試験装置
Document Type and Number:
Japanese Patent JP6905874
Kind Code:
B2
Abstract:
To make it possible, in performing an evaluation test on an improvement effect on natural ground by injection material, to appropriately evaluate the improvement effect by making the injection material be sufficiently diffused into intermediate part of simulated natural ground.SOLUTION: Simulated natural ground 30 is stored inside a test container 10. On the bottom or the top of the simulated natural ground 30 are provided buffer layers 31, 32 having diffusion resistance to injection material 3 higher than that of the simulated natural ground 30 so as to be in contact with the simulated natural ground 30. The injection material 3 is injected into the simulated natural ground 30 from an injection pipe 20 inserted and arranged inside the test container 10.SELECTED DRAWING: Figure 1
