Abstract

The invention discloses a three-axis sample preparation mixing and throwing device and a sample preparation method, relates to the technical field of preparation of mechanical three-axis test samplesof soil, and solves the problem of non-uniform soil property during the preparation of a remolded three-axis test sample with relatively high moisture content and porosity and the problem that inter-stratum soil layers cannot be well connected during layered sample preparation. The three-axis sample preparation mixing and throwing device comprises a fixer, a proofing cylinder, a clamping plate, astirrer and a stirring and throwing rod. The main technical scheme adopted by the invention is that the whole stirring and throwing device is integrally connected with the sample striking cylinder andthe base by means of threaded connection; the stirring and throwing rod is driven through the rotation of a direct current motor to stir and anchor the soil in the proofing cylinder; for each layer of soil sample, the depth of the stirring and throwing rod can be adjusted by a three-claw chuck, so that the soil layers of different depths can be stirred and anchored, and the quality of the test sample is greatly improved.

Description

technical field [0001] The invention relates to a three-axis sample preparation stirring and throwing device, in particular to a triaxial sample preparation stirring and throwing device and a sample preparation method for preparing silty clay samples with relatively high water content and porosity. Background technique [0002] Silty clay usually refers to clay soil with a plasticity index between 10 and 17, and its content of silt group is greater than that of sand group. Widely distributed in my country, this type of soil has poor water stability and is easily eroded during the rainy season, and slope erosion and landslides are prone to occur in extreme weather. Therefore, the study of silty clay is beneficial to the further analysis of landslide and debris flow disasters. The indoor triaxial test can not only accurately measure the shear strength characteristics of the soil, but also analyze the change of the stress path during the shear process through the change of the...
