Embodiment 1
[0026] A sealing method for a fractured rock mass resistant to high osmotic pressure under shearing in this embodiment comprises the following steps:
[0027] Step 1. Device Layout
[0028] Such as figure 1 As shown, two rock masses of the same material are stacked up and down, and the lower surface of the upper fractured rock mass 1 and the upper surface of the lower fractured rock mass 2 form a contact surface 7; the upper surface of the lower fractured rock mass 2 is provided with a circle of concave Groove, the seal ring 5 is placed in the groove; several through holes 3 are drilled up and down inside the upper fractured rock mass 1, and the lower end faces 4 of the through holes 3 are included in the area surrounded by the seal ring 5 of the lower cracked rock mass 2 .
[0029] Step 2. High osmotic pressure resistant seal under shear action
[0030] Water flows in from part of the through hole 3 of the upper fractured rock mass 1, seeps inside the sealing ring 5 of the...
Embodiment 2
[0033] The difference between this embodiment and embodiment 1 is:
[0034] Such as figure 2 As shown, the through holes 3 of the upper fractured rock mass 1 are distributed in a matrix inside the upper fractured rock mass 1 .
Embodiment 3
[0036] The difference between this embodiment and the above two embodiments is:
[0037] The roughness of the upper and lower fissure medium contact surfaces 7, the surface roughness of the groove of the sealing ring 5 and the surface roughness of the water flow medium inside the sealing ring 5 are all in the range of 0-1.6; the diameter of the sealing ring 5 ranges from 0.3m -0.6m.
