Abstract

The invention provides a device for preparing a light-weight remoulded soil sample in the technical field of civil engineering. The device comprises a main bracket structure and a loading system structure, wherein the main bracket structure is placed on a horizontal plane; the loading system structure is arranged inside the main bracket structure; the main bracket structure comprises an upper board, a lower board, a screw and nut component, a sample preparation barrel, a water-permeable stone and a groove-encircling board; and the loading system structure comprises a loading board, a bearing board, a pressurizing rod, a buckling board and an anti-inclination board. By the device, slush prepared from remoulded soil is poured into a device made of organic glass, and a static load is applied to the top to cure he soil sample so as to obtain a saturated remoulded soil test sample with uniform water content.

Description

technical field [0001] The invention relates to a device in the technical field of civil engineering, in particular to a light-duty remolded soil sample preparation device. Background technique [0002] Indoor tests can obtain various physical and mechanical parameters of soil samples, which can provide a basis for engineering design or numerical simulation. In laboratory experiments, appropriate samples must be selected for testing. Because the experimental results of different soils are very different, even small changes in the experimental conditions for the same soil undisturbed soil will lead to completely different experimental results, so the experimental results of undisturbed soil samples are large. , which is not conducive to the application of soil mechanics. Therefore, in the indoor soil engineering experiments in foreign countries, remodeling soil samples with uniform properties and small dispersion of experimental results are mainly used. [0003] The current...
