Abstract
The invention discloses a multi-connected remolded saturated soil sample preparation device, which relates to the field of civil engineering geotechnical tests. The structure of the device is mainly as follows: a sample preparation device is installed on the iron frame; one end of the steel wire rope is fixed on the left cross bar; end connection, the weight is loaded on the hook, and the hook is connected to the left end of the long rod to form a structure for loading and transmitting force to the sample preparation device; in the sample preparation cylinder, from bottom to top, the base, lower permeable stone, soil sample, The upper permeable stone, the cover plate, the vertical bar and the horizontal bar are connected in sequence to form a structure for the soil sample experiment. The invention uses the principle of leverage and fixed pulleys to apply vertical pressure to the thin mud in the sample preparation device, which saves test time for geotechnical tests with many variables and long sample preparation periods; only one set of loading system is needed, which effectively reduces the cost and has the advantages of Better economical and practical.
Description
technical field [0001] The invention relates to the field of civil engineering geotechnical tests, in particular to a multi-connected remolded saturated soil sampling device; in particular to a device for preparing saturated remolded fine-grained soil samples, which is suitable for studying the physical and mechanical characteristics of the chemical action of water and soil Test remolded soil sample preparation. Background technique [0002] In engineering practice, a series of indoor tests will be carried out in order to obtain the physical and mechanical parameters of the soil. At present, the soil samples used in indoor experiments can be divided into original soil samples and indoor remodeled soil samples. Although the undisturbed soil sample can truly reflect the original structure of the soil, due to the limitation of sampling technology and the influence of the environment, the test results are not ideal and the dispersion is large. On the contrary, indoor remolded ...
