Abstract

The invention relates to a device and an operation method for rapidly preparing artificial synthetic transparent soil. The device comprises a particle container, a sliding groove, a sliding perforated plate, a multi-ball bearing, a rotating rod, a fixed track, a fixed perforated plate, a transparent soil container, Screw and bottom support. By adjusting the rotating rod, the relative position of the cylindrical hole of the sliding perforated disk and the conical hole of the fixed perforated disk can be set, and the scattered amount of solid particles can be controlled; by adjusting the screw, the relative position of the particle container and the transparent soil container can be set, which can be controlled The scattering rate of solid particles; by setting a solution guide groove and a solution outlet around the top of the transparent soil container, the pore solution that has been displaced and overflowed during the scattering of solid particles can be recovered; the above methods can be used to quickly and efficiently prepare artificial synthesis without air bubbles intrusion Transparent soil, and can save the cost of transparent soil preparation.

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
