Embodiment 1

[0042] Example 1 Preparation of transparent rock.

[0043] A kind of method that utilizes natural silica raw material to make transparent rock that the present invention proposes comprises the following steps:

[0044] (1) Material selection: Take the natural silica material block, clean the surface stains of the natural silica material, and remove the natural silica material block with high impurity content according to visual inspection. The particle size of the natural silica material varies, and appropriate manual crushing can be carried out Filling and removing parts with high impurities;

[0045] (2) Primary melting: Primary melting is realized in the first boiler. The first boiler of this embodiment is a cylinder with a height of 2m, an inner diameter of 2m, and a height of 2m, with a volume of about 6.3m 3 , in the middle of the first boiler, an activated carbon rod capable of absorbing impurities is arranged, and activated alumina is arranged around to absorb impuri...

Embodiment 7

[0059] Example 7 Preparation of transparent rock mass.

[0060] The preparation steps are the same as in Example 1, the difference is that in step (8) mold making, the ceramic cloth is arranged inside the mold according to the design position, the ceramic cloth is 25mm long, 10mm wide, and 1mm thick, and the angle between the long side direction of the ceramic cloth and the horizontal is 45° distribution.

Embodiment 8

[0061] Example 8 Preparation of transparent rock mass.

[0062] The preparation steps are the same as in Example 1. The difference is that in step (8) mold making, colored and flaky quartz are arranged inside the mold according to the design position. The quartz is 20mm long, 12mm wide, and 2mm thick. Colored, flaky quartz The distribution angle with the horizontal is 35°.

Abstract

The invention discloses application of a natural silica material in preparation of a transparent rock and a transparent rock body. The transparent rock and the transparent rock body are prepared by the following steps: selecting the natural silica material which is low in impurity content; sequentially melting for the first time and crushing for the first time; choosing for the second time, cleaning, crushing for the second time, and melting for the second time; and casting in a mold, and disassembling the mold, so as to prepare the transparent rock and the transparent rock body. An activated carbon rod capable of adsorbing impurities is put in the center of a boiler in the melting process; and an activated aluminum oxide impurity-adsorbing material is arranged at the periphery of the boiler. The transparent rock and the transparent rock body prepared by the method have good transparent effects, and can be effectively applied to a geotechnical engineering model; visualization of internal deformation of the rock and the rock body is achieved; the natural rock and rock body can be widely replaced for simulating the complicated geological conditions. Meanwhile, the method disclosed by the invention is simple and convenient to operate, easy to achieve, low in cost, and wide in applicability.

Description

technical field [0001] The invention belongs to the technical field of civil engineering visualized model tests, and is mainly used in the teaching and scientific research of civil engineering indoor model tests, specifically relates to a transparent rock and rock mass, and more specifically relates to the use of natural silica materials in making transparent rocks and transparent Application in rock mass. Background technique [0002] In the model test of geotechnical engineering, it is of great significance to study the internal deformation law and mechanism of rock (body) to explore the nature of geotechnical engineering problems. At present, the conventional rock (body) indoor model test technology uses gypsum and other materials to artificially make samples to simulate natural rock (body), and embeds displacement, stress and temperature measurement components inside the sample; rock (body) For internal deformation, the displacement of some discrete points can be measur...
