Abstract

The invention relates to an apparatus for a layered undisturbed soil seepage experiment. The apparatus comprises a pedestal, a seepage column connected to the pedestal, an upper end cover on the seepage column, a flowmeter, a silicone tube connected with the flowmeter, an overflow tank connected with the flowmeter through the silicone tube and a multi-parameter analyzer connected with a sensor onthe seepage column through a signal line. The invention can be used for determining penetration coefficient and dispersion coefficient in undisturbed soil in production, researching on influence of soil amendment on soil mechanical properties, researching on influences of leaching of different solutions on soil structure and influence of soil midstream on unsaturated zone soil and underground water, can also be applied to parameter determination in the relevant field of solute migration and can be used as a teaching apparatus.

Description

technical field [0001] The invention relates to a soil experiment device, in particular to a device used for layered undisturbed soil seepage experiments. Background technique [0002] Seepage test is an important means to study the migration and transformation of seepage fluid and the change of soil properties during the interaction between soil and groundwater. It is an important method to measure parameters such as permeability coefficient and diffusion coefficient. At present, traditional seepage experiments mostly use one-dimensional soil columns and seepage tanks, which can only be loaded with soil samples layer by layer and then tested, and seepage experiments of undisturbed soil cannot be carried out. However, after the soil is violently disturbed, the structure of the soil is destroyed, causing great changes in properties such as permeability, dispersibility, and shear and compressive strength, which cannot truly reflect the real situation of the soil in the field. ...
