Device for quickly preparing artificially synthesized transparent soil and operation method

Abstract

The invention relates to a device for quickly preparing artificially synthesized transparent soil and an operation method. The device comprises a particle container, sliding grooves, a slidable bored disc, multiple ball bearings, rotating rods, fixing rails, a fixed bored disc, a transparent soil container, threaded rods and bottom support seats. The relative position of cylindrical bores of the slidable bored disc and conical bores of the fixed bored disc can be arranged by regulating the rotating rods to control the falling quantity of solid particles; the relative position of the particle container and the transparent soil container can be arranged by regulating the threaded rods to control the falling speed of the solid particles; pore solutions which are extruded to flow over in the falling process of the solid particles can be recycled by forming solution guide grooves and solution outlets in the periphery of the top of the transparent container; through the above means, the artificially synthesized transparent soil with no air bubble to invade can be quickly and efficiently prepared, and the preparation cost of the transparent soil can be saved.

Description

technical field [0001] The invention relates to a preparation method of artificial synthetic transparent soil, in particular to a technology and operation method for quickly preparing artificial synthetic transparent soil. Background technique [0002] With the appearance of transparent soil in the 1990s and its application in geotechnical engineering physical simulation tests, it became possible to continuously observe the deformation of any point inside the soil without intrusion. Transparent soil is composed of transparent solid particles and pore solution with matching refractive index. The transparency of transparent soil is the most important factor affecting the practicability of transparent soil. At present, the factors affecting the transparency of transparent soil include: ①Cleaning of solid particles ②The colorlessness and refractive index matching of the pore solution, ③The variability of the surrounding temperature and ④The incorporation of air bubbles.

Transparent soil is composed of transparent solid particles and pore solution with matching refractive index. The transparency of transparent soil is the most important factor affecting the practicability of transparent soil. At present, the factors affecting the transparency of transparent soil include: ①Cleaning of solid particles ②The colorlessness and refractive index matching of the pore solution, ③The variability of the surrounding temperature and ④The incorporation of air bubbles. Among them, ① and ② can be solved by selecting appropriate preparation materials. For ③, It can be solved by preparing and testing transparent soil under constant temperature conditions. However, for ④, the current solution is to manually scatter solid particles into the pore solution, but this method is too slow. It may take a day or more for transparent soil samples. In addition, in the process of manual scattering, the scattering distance of solids should be as close as possible to the surface of the pore solution, which is a great test for the human body itself.

In addition, during the preparation process, the overflow pore solution in the transparent soil test container is often lost. The pore solution is mixed with expensive oil bodies. The cost of oil bodies accounts for the majority of the total cost of transparent soil. Therefore, the traditional method causes A certain amount of cost wasted
