Embodiment 1

[0031] see Figure 1-6 , the present invention provides a device for measuring the migration mass of gaseous water in unsaturated soil, specifically as figure 1 As shown, it includes a base 1, a ring cutter 2, a spacer 4, a filter paper fixing gasket 5, a filter paper 6, a pull rod 7, and a nut 8; the base 1 can be disassembled and embedded in the ring cutter 2; the ring cutter 2 contains A soil sample 3; a spacer 4 is installed on the upper part of the base 1; a filter paper fixing spacer 5 is installed on the upper part of the spacer 4;

[0032] Follow the steps below for specific operations:

[0033] 1) Use ring cutter 2 to cut soil with designed density and moisture content to form soil sample 3, put ring cutter 2 containing soil sample 3 into base 1, the density and moisture content can be determined by compaction curve of soil sample, It can also be any density and water content that can make the soil sample stable in the ring knife and not drop slag;

[0034] 2) Dete...

Abstract

The invention provides a device for measuring the migration quality of gaseous water in unsaturated soil, which includes a base, a ring cutter, a spacer, a filter paper fixing gasket, filter paper, a pull rod, and a nut; the base can be disassembled and embedded in the ring cutter; the The inside of the ring knife contains soil samples; the upper part of the base is installed with a spacer; the upper part of the spacer is equipped with a filter paper fixing gasket; the device is a vertically symmetrical structure connected as a whole by a pull rod and a nut. The device is simple in structure, easy to implement, easy to operate, low in cost, and convenient to realize the measurement of gaseous water migration quality at different distances, different times, and different temperatures in soil samples of different heights, different moisture contents, and different densities, ensuring The experimental results are accurate and credible, and it is an efficient and practical device for measuring the migration mass of gaseous water in unsaturated soil.

Description

technical field [0001] The invention relates to the technical field of geotechnical testing instruments and equipment, in particular to a device for measuring the migration mass of gaseous water in unsaturated soil and a method for using the same. Background technique [0002] The change of water content in unsaturated soil will have an important impact on its deformation and strength characteristics, resulting in disasters such as subsidence, bank collapse, cracking, and slope instability. Moisture migration in unsaturated soil is the cause of changes in water content. Moisture migration is mainly divided into gaseous water migration and liquid water migration. There are relatively few studies on the law of water migration under low water content in my country, and there is currently a lack of measurement methods for the quality of gaseous water migration in unsaturated soils. [0003] The measurement of the mass of gaseous water migration in unsaturated soil is a key step...
