Abstract

The invention discloses a nuclear magnetic resonance test non-magnetized saturation test sample preparation device and a preparation method thereof, and belongs to the related field of geotechnical engineering indoor test devices. The device comprises a funnel device and a sample preparation-saturation tube. The funnel device is connected with the sample preparation-saturation tube in an overlapping manner; the sample preparation-saturation tube is made of a polytetrafluoroethylene transparent material with a scale on the side wall; the top of the sample preparation-saturation tube is providedwith a top permeable stone; a saturator hood reversely covers the top permeable stone and the upper part of the sample preparation-saturation tube; the bottom of the sample preparation-saturation tube is provided with a bottom permeable stone; the sample preparation-saturation tube and the bottom permeable stone are located inside a saturator base; clamping slots are formed in both the saturatorhood and the saturator base; a clamping belt is fastened in the clamping slots to fixedly connect the saturator hood, the top permeable stone, the sample preparation-saturation tube, the bottom permeable stone and the saturator base with one another. The device disclosed by the invention is simple in structure; the preparation method is easy to operate; the nuclear magnetic resonance test non-magnetized saturation test sample preparation device and the preparation method thereof are provided.

Description

technical field [0001] The invention relates to the technical field of indoor geotechnical tests of geotechnical engineering, in particular to a device for preparing non-magnetized saturation samples for nuclear magnetic resonance tests and a preparation method thereof. Background technique [0002] In the field of geotechnical engineering, the microstructure of soil has always been a matter of concern to everyone, so a large number of laboratory tests will involve testing and research on the distribution and content of pores inside the soil. Researchers using SEM technology and mercury intrusion technology can only study the microscopic pore structure qualitatively. With the development of nuclear magnetic resonance technology, researchers use the transverse relaxation time T of nuclear magnetic resonance 2 Distribution Quantitatively studies the distribution and content of microscopic pores in soil, and involves sample preparation, saturation, and sample measurement in th...
