Abstract

The invention discloses an underwater sand rain method device for transparent soil preparation and a use method of the underwater sand rain method device. The device comprises a rotor, a leakage-proof device and a funnel. When the anti-leakage device is used, the rotating head of the rotor is placed in the sleeve of the anti-leakage device, the lower end of the funnel penetrates through the through hole I of the rotating head, the rotating head is filled with the transparent soil preparation material through the funnel, after the rotating head is filled with the transparent soil preparation material, the funnel is removed, and the through hole I is blocked by the rubber plug. The rotating head and the sleeve are placed below the liquid level of the pore liquid in the transparent soil model groove together, and then the leakage-proof device is removed. Standing for a preset time, after bubbles in the transparent soil preparation material are completely discharged, starting a motor, driving a rotating head to rotate at a constant speed, scattering the transparent soil preparation material into the pore liquid, and uniformly stirring with a glass rod. And repeating the operation until the preparation of the transparent soil is completed. Sandy soil is scattered into pore liquid through constant-speed rotation of the rotating head, bubbles brought in in the transparent soil preparation process are effectively reduced, the preparation efficiency is improved, and the test workload is reduced.

Description

technical field [0001] The invention relates to the technical field of transparent soil model tests, in particular to an underwater sand and rain method device for transparent soil preparation and a method for using the same. Background technique [0002] Soil deformation measurement is an important content in soil mechanics test. The traditional test method is limited by the opaque nature of the soil, and it is often only possible to obtain the deformation of the surface of the soil, and it is difficult to obtain the deformation of the interior of the soil. For this reason, scholars at home and abroad have carried out a lot of research and proposed a lot of solutions. However, these solutions often belong to contact measurement, which will have a certain impact on the deformation behavior of the soil, causing interference to the test results. The high cost of testing also limits the widespread application of these methods. [0003] With the development of digital image p...
