Layered sectioning device for soil body microstructure

Abstract

The invention discloses a layered sectioning device for a soil body microstructure. The layered sectioning device is composed of a case, a micromotion precise positioning platform, servo drivers, a soil body sample clamp, a high-speed milling mechanism and a control panel. The layered sectioning device is characterized in that a soil body sample does X-axis, Y-axis and Z-axis micron-grade precision motion under a milling cutter through the precise positioning platform, so that all sectioning points are aligned to the same position in the multiple sectioning processes, meanwhile, feeding is carried out at the micron-grade resolution ratio for milling, and the soil body microstructure is sectioned into multiple sectioning faces; meanwhile, the high-speed milling mechanism is adopted to make the sectioning faces formed by milling flat as much as possible and be approximately planar to be detected conveniently. According to the layered sectioning device for the soil body microstructure, a sectioning layer number set value and a sectioning starting instruction are input through a touch screen of the control panel, a system can be in an automatic sectioning mode, and milling of the set sectioning layer number is completed. The soil body microstructure sectioning device has the main advantages of being high in accuracy, automatic, compact in structure and convenient to operate and use, and the distance between the sectioning faces of the soil body sample is smaller than the size scale of the sample microstructure.

Description

technical field [0001] The invention belongs to the field of testing instruments for rock and soil materials, in particular to a soil microstructure layer cutting device for extracting soil microstructure images. Background technique [0002] The stability and deformation of the foundation are important issues related to the safety of civil engineering. Aiming at the stability and deformation of the foundation, the current academic circles have carried out a lot of research on the macro and meso scales of the soil, but the research on the micro structure of the soil is relatively limited. Less, insight into the structural properties of soil from the microscopic scale is of great significance for a deeper understanding of foundations and prevention of collapse. [0003] At present, most of the research methods for the detection of soil microscopic properties use scanning electron microscopes to take surface images, which have the advantages of high resolution and relatively l...

When using an optical microscope to observe the surface of the soil, due to the extremely small depth of field of the high-magnification microscope, only the two-dimensional soil microstructure located in the focal plane can be clearly imaged, while the microstructure away from the focal plane is blurred.
