Abstract

The invention provides a soil disintegration tester, which at least comprises a graduated scale, a screen and a blister provided with a high density matter. The screen is suspended at a lower end of the graduated scale. The blister provided with the high density matter is connected to a lower end of the screen. The graduated scale, the screen and the blister provided with the high density matter are positioned in a container holding a liquid. The soil disintegration tester has simple structure, convenient use, convenient maintenance and capacity of measuring indexes of a soil sample, such as the disintegration amount, the disintegration speed, the disintegration form, the size grading of a disintegrating object and the like, and can be widely used in the fields of scientific research of the geotechnical engineering, teaching practice and production.

Description

Technical field: [0001] The invention relates to a soil disintegration instrument, which is a geotechnical engineering test instrument for measuring soil disintegration. Background technique: [0002] In the fields of geotechnical engineering scientific research, teaching practice and production, when measuring physical and mechanical indexes in geotechnical engineering tests, it is sometimes necessary to study the disintegration of soil samples, but there is no corresponding soil disintegration measuring instrument at present. Therefore, it is very necessary to develop a soil disintegration instrument that is easy to use, easy to maintain, and has high cost performance. Invention content: [0003] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a soil disintegration instrument, the soil disintegration instrument is simple in structure, easy to use, easy to maintain, and the disintegration amount, disintegration speed,...
