Embodiment Construction
[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementation methods.
[0030] A device for testing the permeability coefficient of fractured rock mass under different water pressure conditions of the present invention is as follows: figure 1 As shown, it consists of test equipment, water inlet equipment and calculation equipment.
[0031] Test equipment such as figure 2 Shown includes water pressure box 6, base box 13 and the limiter between the two (the limiter plays a supporting and fixing role).
[0032] Such as image 3 As shown, the water pressure box 6 is in the shape of a cuboid as a whole, and the upper part is provided with a water inlet valve 4, and the bottom plate of the water pressure box 6 has an upper sample groove 20, and the size of the groove is slightly larger than the size of the rock sample 7; the base box 13 A lower sample slot 19 is opened on the top plate, correspon...
