Infiltrating-concretion experiment device with a plurality of experiment control conditions and using method

Abstract

The invention discloses an infiltrating-concretion experiment device with a plurality of experiment control conditions and a using method. The infiltrating-concretion experiment device comprises a protective ring of an annular structure, an experimental soil sample is arranged in the protective ring, a piston is arranged on the upper part of the protective ring, a displacement meter guiding rod isarranged on the upper part of the piston, a displacement meter frame is arranged on one side of the outer part of the protective ring, and the horizontal section of the displacement meter frame is suspended on the upper part of the displacement meter guiding rod; the deformation of the soil sample is surveyed through the displacement meter guiding rod, a lower protective ring is sleeved on the lower part of the protective ring, the upper part of the protective ring is connected with a water storage cup through a pipeline, the lower protective ring is connected with a pore pressure device andthe water storage cup through pipelines, and the lower protective ring is used for observing the pore water pressure variation rules and the water outlet amount of the concretion experiment. The infiltrating-concretion experiment device solves the problems of repeated manufacturing of a soil sample converting instrument is tedious, the experiment condition is simplex, and the displacement volume is imprecise existing in the prior art.

Description

technical field [0001] The invention belongs to the technical field of soil mechanics test devices, and in particular relates to a seepage consolidation test device capable of multi-test control conditions and a use method. Background technique [0002] The main instruments for soil sample penetration test in the prior art are the constant head permeameter in the "constant head permeation test" and the variable head permeameter in the "variable head permeation test" described in the "Standards for Geotechnical Test Methods". The above instruments can only perform simple permeability tests, but cannot quantitatively and uniformly apply the consolidation pressure, so it is difficult to accurately obtain the void ratio, resulting in inaccurate test data. In the prior art, the instrument used for the consolidation test is a compression tester, and the pressurization condition is generally of the weight type or the lever type. This instrument only performs partial compression cha...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a kind of seepage consolidation experimental device and method of use that can control the conditions of multiple experiments in view of the above-mentioned deficiencies in the prior art, which solves the problem of repeatedly making soil sample conversion instruments in the prior art. cumbersome, single experimental conditions, inaccurate drainage volume, etc.
