Example Embodiment

[0021] see Figure 1-3 , An anti-seepage device provided by the embodiment of the present invention is provided in a rock sample 1, a drill hole 1-1 and a seepage hole 1-2 are opened in the rock sample, and the drill hole 1-1 is communicated with the seepage hole 1-2 , the diameter of the seepage hole 1-2 is smaller than the diameter of the borehole 1-1, and the anti-seepage device includes: a flexible joint 2, a blocking piece 3, a filling piece 4, a piercing piece 5 and an extrusion piece 6.

[0022] The packing 4 can communicate with the seepage hole 1-2 through the bore hole 1-1.

[0023] The first end of the flexible joint 2 is arranged in the bore hole 1-1, and the flexible joint 2 is provided with a flow channel.

[0024] The blocking member 3 is fixedly arranged on the first end of the flexible joint 4 .

[0025] The extrusion part 6 can be arranged in the flow channel, and the outer diameter of the extrusion part 6 is larger than the inner diameter of the flow chann...

Abstract

The invention discloses an anti-seepage device, a shear box and a using method of the anti-seepage device, and belongs to the technical field of stress seepage coupling. The anti-seepage device comprises a flexible joint, a plugging piece, a filling piece, a piercing piece and an extruding piece, wherein the filling piece can penetrate through a drill hole to be communicated with a seepage hole; the first end of the flexible joint is arranged in the drill hole, and a flow channel is formed in the flexible joint; the plugging piece is fixedly arranged at the first end of the flexible joint; the extruding piece can be arranged in the flow channel, and the outer diameter of the extruding piece is larger than the inner diameter of the flow channel; and the piercing piece is fixedly arranged at the end part of the extruding piece, and the piercing piece can penetrate through the plugging piece to enter the seepage hole. According to the anti-seepage device, the shear box and the using method of the anti-seepage device, the waterproof effect of a stress seepage coupling experiment can be guaranteed, and it is guaranteed that the experiment result is accurate.

Description

technical field [0001] The invention relates to the technical field of stress seepage coupling, in particular to an anti-seepage device, a shear box and a method for using the anti-seepage device. Background technique [0002] Under the action of in-situ stress, the rock mass of the high and steep slope is subjected to a shear force directed to the space, and the rock mass will rheology under the long-term action of the shear force; under the condition of continuous rainfall, the internal rock mass of the high and steep slope Due to the existence of voids and fissures, a water column with a height of 100 meters will be formed in the body. Therefore, under the action of high water pressure, the high water pressure will change the stress state of the rock mass inside the slope, deteriorate the physical and chemical properties of the rock mass, and cause the rheological rate to accelerate. , resulting in slope instability. [0003] In order to explore the influence of high wat...
