Problems solved by technology

[0003] In the existing mechanical test device for studying water-rock interaction, the pressure chamber can provide confining pressure with water, and can observe the specimen while loading, but its main disadvantages include: the existing pressure chamber can have a transparent window on the side wall, Or directly use transparent material as the side wall of the pressure chamber, but the material of the transparent window can bear less confining pressure, and sometimes cannot meet the requirements of the mechanical test; the liquid that provides the confining pressure in the existing pressure chamber cannot circulate and cannot Replacement during the test

Embodiment Construction

[0016] The use mode of the present invention will be described in detail below in conjunction with the accompanying drawings.

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

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

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...
