Problems solved by technology

[0003] 1. Applicable to single soil
Soils with different properties, such as homogeneous soil, cracked soil, interbedded soil, garbage soil, frozen soil, and soil containing geosynthetic materials, have different requirements on the size and function of the permeability tester. design, equipment utilization is low and uneconomical
[0004] 2. Single control of seepage conditions
The plexiglass cylinder of traditional test equipment is not easy to prepare samples due to its high height, and it is difficult to accurately control the initial key control parameters of the test such as sam

Abstract

The invention discloses a modular soil body permeability tester. The modular soil body permeability tester comprises a soil body seepage system, a seepage condition control system and a data acquisition system. According to the modular soil body permeability tester, different modular components are assembled to simulate various test conditions so as to scientifically and effectively research the seepage characteristics of a soil body. The modular components include a top box, an organic glass cylinder, a bottom box, an artificial rainfall module, a reversed filter component and the like. According to the modular soil body permeability tester, the mounting and the detaching are convenient, the preparation of samples is facilitated, and water is recycled in a seepage process, so that the water resource can be saved; besides, each modular component can be freely selected and arranged aiming at different research purposes, so that the tester has height expandability and can meet various test requirements; by utilizing a modular design idea, the tester has the advantages of diversity, economy, high efficiency, expandability and the like, and measured test parameters are accurate.

Description

technical field [0001] The invention relates to a measuring device for a soil permeability coefficient curve and a soil-water characteristic curve, in particular to a measuring device capable of measuring homogeneous soil, cracked soil, interbedded soil, garbage soil, frozen soil and soil containing geosynthetic materials Modular soil permeability tester with permeability coefficient curve and soil-water characteristic curve. Background technique [0002] The permeability of soil reflects the ability of soil to transmit water, which is one of the basic properties of soil and an important engineering characteristic concerned by geotechnical engineering. A large number of geotechnical engineering cases show that the disaster-causing mechanism is closely related to soil permeability. Therefore, obtaining accurate soil permeability parameters through experiments has important academic significance and practical value. The permeability of soil is closely related to factors such...
