Multi-partial loading fully-transparent pressure chamber

Abstract

The invention relates to a multi-partial loading fully-transparent pressure chamber, which belongs to the technical field of experiment apparatus manufacture. The multi-partial loading fully-transparent pressure chamber has four pressure chambers nested and cooperated by four fully-transparent hollow cylinders from inside to outside in order. When the innermost pressure chamber bears large pressure, the external pressure chamber can be used, the internal and external pressures of four fully-transparent hollow cylinders are gradually decreased, partial pressure can be realized by keeping a constant pressure difference, and the normal working at a high pressure state of the pressure chamber is ensured.

Description

Technical field: [0001] The invention relates to the field of geotechnical engineering, in particular to a pressure chamber for geotechnical triaxial tests. The pressure chamber is fully permeable and can withstand high pressure. Background technique: [0002] For rock and soil, triaxial test is very important, it can simulate the rupture test of rock and soil in real environment. But now the pressure chamber of the triaxial testing machine cannot meet our requirements. When we need higher pressure for testing, we can only use steel pressure chambers. Since steel pressure chambers are opaque, we cannot observe the relevant changes of cracks on the rock and soil from the outside, although there are now permeability chambers on the market. Pressure chamber, but cannot withstand higher pressure. It can be said that the existing pressure chambers have limitations and cannot well meet our test requirements. According to the status quo, we have developed a fully permeable pres...
