Example Embodiment

[0016] The usage mode of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] like figure 1 As shown, a fully permeable water circulation pressure chamber for a rock test of the present invention consists of a fully permeable pressure chamber A and a dynamic water circulation system B.

[0018] Among them, the fully transparent pressure chamber A consists of the pressure chamber base A2, the clamp A3, the pressure chamber lower end cover A4, the connecting bolt A5, the pressure chamber transparent cylinder A6, the pressure chamber upper end cover A7, the loading shaft A8, the LED lamp A11, the upper The loading gasket A12 and the lower loading gasket A14 are composed, such as figure 2 shown. The transparent cylinder body A6 of the pressure chamber is fixed by the upper end cover A7 of the pressure chamber and the upper end cover A4 of the pressure chamber, and the contact is sealed with an O-ring A10. The upper end co...

Abstract

The invention provides a full-transparent water circulation pressure chamber for a rock test. The full-transparent water circulation pressure chamber is composed of a full-transparent pressure chamberand a flowing water circulation system. The full-transparent side walls of the pressure chamber can be provided for simultaneous loading and observation of a rock test piece, the large confining pressure needed by the rock mechanics test can be borne, circular flowing or replacing of confining pressure liquid can be achieved in the test process, and quite wide application prospects are achieved.

Description

Technical field: [0001] The invention belongs to the field of rock mechanics test instruments, in particular to a fully permeable water circulation pressure chamber for rock mechanics tests, which is suitable for simulating the complex water environment where rocks exist, and can circulate and replace confining pressure liquid during the test process, and The failure process of rock samples can be observed. Background technique: [0002] The interaction of rock and water is a common problem in the field of civil engineering. Some rock masses have good mechanical properties in their natural state, but their mechanical properties often change when exposed to water. When rock interacts with water, under the action of confining pressure, micro-cracks will be formed on its surface. As the water-rock interaction proceeds, micro-cracks will continue to expand, extend, and merge, and the strength of the rock will continue to decrease. penetration leading to rock destruction. It c...
