Problems solved by technology

[0006] The purpose of the present invention is to only be limited to some conventional soil types for existing soil undisturbed sample sampling and preparation technology, has avoided many gravel soils, can't be cut for the existence of hard gravel in soil and in making because gravel is relatively In order to solve the problem of not being able to fix for a long time, we invented a method of collecting and making a 1 m whole section of gravel soil samples by "field photography - numb fixation - gravel glue - in situ sticking"

Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0039] Such as Figure 1-3 shown.

[0040] The invention discloses a method for collecting and preparing a 1 m whole section of a gravelly soil sample, which comprises collecting and making a specimen of a full section of gravel soil column. Among them, before collecting the entire soil column with many gravels, the wooden box (sample storage box) containing the entire soil column was bound with an electric drill. The size of the wooden box was the same as the conventional one, 100cm×22cm×6cm. Then choose a natural gravel surface with the best angle, remove the obstacles around it with a military shovel, hang a ruler, and shoot it with a high-resolution digital SLR camera ( figure 1 ). After dividing the layers, first take out the first layer with a shovel, put it in the wooden box in place, and then take out one layer after another. The upper and lo...

Abstract

The invention relates to a method for collecting and preparing a 1m original whole specimen of multi-gravel soil. The method comprises the steps of collecting a field specimen and preparing an indoorspecimen. The method is characterized in that a 'field shooting-numb fixing-gravel gluing-in situ pasting' method is adopted for collecting and preparing the specimen. The method provided by the invention is popular and easy to understand and is easy for operation; a soil column is restored by referring to photos, so that the natural texture of soil column is kept; the profile is taken out layer by layer from top to bottom, the operation is convenient and the soil layer structure is not damaged.

Description

technical field [0001] The invention relates to a collection and preparation technology of soil samples, in particular to a method for collection and preparation of soil samples with poor viscosity, in particular to a method for collection and preparation of 1 m whole section of gravel soil samples. Background technique [0002] The collection and production of the 1 m whole section of soil samples is to collect the 1 m deep soil entity in the original state, and then post-processing indoors to make the whole section of the soil entity can be visually displayed, which is used for historical archiving and popular science display. [0003] Existing techniques for collecting and making 1 m whole section of soil samples are generally only suitable for conventional or ideal soils with certain viscosity and mainly composed of fine soil. There are certain gravels in some soils in nature. The existence of gravels makes it difficult to collect 1 m soil in its original state and fix t...
