Embodiment Construction

[0024] The present invention will be further described below in conjunction with accompanying drawing:

[0025] Depend on figure 1 It can be seen that a stress-water flow-chemical coupling rock uniaxial compression mesomechanics test device of the present invention includes a box body 1, a pair of loading shafts 2, two faucets 3, a water pump 4, a control valve 5, and two water pipes 6. Container 7; the box body 1 is a hollow cuboid with an open top, one side of which is made of hard transparent material 8 such as plexiglass, and the other parts are made of stainless steel. The shafts 2 are cylinders, the size of which matches the round holes, and are respectively installed in the two round holes. The space between the loading shaft 2 and the round holes is sealed with an O-ring, and the upper and lower sides of the transparent material 8 of the box body 1 Each water nozzle 3 is installed, and the upper water nozzle 3 is as close as possible to the top of the box body 1 and c...

Abstract

This invention discloses a stress and flow and chemical couple rock single axis accurate observe test apparatus, which comprises box 1,a pair of load axis 2, two water mouth 3, water pump 4, control valve 5,two pipes, container 7. It is characterized by the following: to fix water mouths 3 on top and bottom of the other side of transparent material of the box, wherein the top mouth is connected with pipe as outlet and the bottom mouth is connected with pump through control valve and pipe as inlet.

Description

Technical field: [0001] The invention relates to a rock mesomechanics test, in particular to a mesomechanics test of the whole process of deformation and fracture under the coupling action of rock uniaxial compression stress-water flow-chemical coupling. It is suitable for rock mesomechanical loading tests considering the effects of unidirectional compressive stress, water flow, chemical corrosion, etc. Background technique: [0002] The research on the chemical-water flow-stress coupling process of fractured rocks is one of the most advanced topics in the field of international rock mechanics. It is one of the most basic research topics of many water-related rock engineering, which has very important scientific significance. It is mainly reflected in that, on the one hand, water is the most active factor among many factors affecting the safety of rock engineering. After the rock and soil are eroded by the chemical solution, the physical and mechanical properties of the ro...
