Three-direction cutting ring soil sample cutting instrument

Abstract

The invention relates to technique for rapidly cutting an indoor test soil sample in three directions, in particular to an innovative technique which can control the size and the shape of the soil sample, can rapidly cut the soil sample and belongs to the detection of the soil sample preparation. In order to maximally utilize the soil sample and well acquire the parameter of each part of soil sample, the invention designs a special mold which is shaped like a drum and a barrel, and the mold is suitable for performing physicochemical parameter test on an undisturbed sample, a compressed sample and a cut sample. Specific parameters of the mold can be set according to the experiment demand by referring to a drawing. G groups of cutting rings, h groups of cutting rings and i groups of cutting rings are mutually cooperated to cut the soil sample in three directions, so that the soil sample can be maximally utilized, different parts of the soil sample can be compared and researched, so that whether a series of physicochemical parameters such as water content and porosity are related to the distribution position or not can be observed. One soil sample can be cut into 144 (6*6*4) blocks, the corresponding cutting rings can be reduced according to the experiment demand, ad the sample quantity varies in the range of 2 to 144.

Description

Technical field: [0001] The invention relates to a technical method for three-way rapid cutting of soil samples in indoor experiments, which can especially control the volume, shape and rapid cutting of soil samples, and belongs to the innovative technology of soil sample preparation and detection. Background technique: [0002] In the process of preparing soil samples in the experiment, most of them are cylinders, and the analysis of their physical and chemical properties is often performed on the corners, so that the data obtained is often single. Even if a few more samples are taken as average samples, the samples are not representative Therefore, the physical and chemical parameters of soil samples cannot be obtained very accurately. [0003] At present, the existing methods of cutting soil samples at home and abroad are mainly ring cutters, soil cutters, and undisturbed soil sample dividers, etc. Most of the above-mentioned instruments are of fixed size and shape, which...

Problems solved by technology

[0003] At present, the existing methods of cutting soil samples at home and abroad are mainly ring cutters, soil cutters, and undisturbed soil sample dividers, etc. Most of the above-mentioned instruments are of fixed size and shape, which wastes a lot of soil samples; at the same time, if multiple experiments are performed, it is necessary to repeat the samples , such a waste of manpower, material resources and time
