Problems solved by technology

Under the current technical conditions, when making specimens, the collected soil columns are put into wooden boxes and displayed directly. Such specimens are untreated, so it is difficult to preserve them for a long time, and they are too heavy to be transported, especially because they cannot reflect the soil. structural condition

Embodiment 1

[0008] A method for making a soil sample, the steps of which are as follows: drilling treatment: drilling holes on the soil column, making 1 to 2 small holes per square centimeter, with a depth of 3 to 4 cm and a diameter of 0.5 to 1 mm, so that the entire The surface of the soil column is covered with small holes to increase the surface area; dipping treatment: lay the soil column flat, pour the impregnating agent in the middle of the soil column, scrape the impregnating agent to both sides of the specimen with a thin wooden board, and the impregnating agent is made of white latex and thinner composition (thinner can be water), the mass ratio of described white latex and thinner is 3: 7~4: 6, then, make the surface of soil sample keep one layer of paint layer, use white latex next day: dilute The mass ratio of the impregnating agent is 1:1 to impregnate the soil for the second time, and then soak it with undiluted white latex after three days; Paste the sackcloth: After the so...

Embodiment 2

[0010] 1. Drying treatment: Lean the collected soil column against the wall and let it dry naturally. Generally, it takes a few days to a week to dry.

[0011] 2. Glue dipping treatment: Lay the soil column flat, pour the impregnating agent in the middle of the soil column on one surface of the soil column, and scrape the impregnating agent to both sides of the soil column with a thin wooden board, but the impregnating agent should not flow to the soil column. Go to the seam of the box on both sides. The soil should be thoroughly soaked for the first time. Then, keep a layer of paint on the surface of the soil sample. The next day, use a thicker impregnating agent (50% white latex and 50% thinner. The thinner can water) soak the soil for the second time, and then soak it with undiluted white latex three days later.

[0012] 3. Paste the sackcloth: After the soil column is impregnated with the last raw glue, immediately spread a piece of sackcloth on it, and paint it repeatedly...

Abstract

The invention relates to a making method of a soil monolith, comprising the following steps of: drilling treatment, gum-dipping treatment, linen pasting, bottom board pasting, monolith finishing and gum-spraying and shaping. After the drilling treatment is carried out to the soil monolith, gum and pillars fully contact, and then a soil displaying device made by a method of pasting bottom board on linens and other methods through the simultaneous actions of gums with different concentrations enables the pillars to be preserved for a long term. Furthermore, the original-shape structure of soil is trimmed by using knives, small needles, hooklets and the like so that the upper and lower levels and the structural condition of the soil are visually reflected.

Description

technical field [0001] The invention belongs to the technical field of soil research, and in particular relates to a preparation method of a soil sample. Background technique [0002] Soil samples are used for detailed research and observation of soil indoors or as exhibitions and teaching demonstrations. It is mainly divided into three categories: bulk soil samples, classified carton samples and whole section samples. Under the current technical conditions, when making specimens, the collected soil columns are put into wooden boxes and displayed directly. This kind of specimens are untreated, so it is difficult to preserve them for a long time, and they are too heavy to be transported, especially they cannot reflect the soil. structural condition. Contents of the invention [0003] Technical problem: In view of the above problems, the present invention provides a method for making soil samples. The soil samples prepared by this method can be stored for a long time and a...
