Description

Visualization seepage flow test device for the test of rock fracture seepage simulation
Technical field
This utility model relates to rock fracture seepage simulation test field, especially a kind of for rock fracture seepage simulation The visualization seepage flow test device of test.
Background technology
At present in the engineerings such as tunnel excavation, slope reinforcement, deep pit digging, mining, rock fracture is to engineering The fracture seepage of stability important, particularly rock is cause that Groundwater Disasters, tunnel internal seep water important former Cause, there is important impact in the crack of different angle on rock fracture seepage flow simultaneously.In existing technology, China Patent No. is The patent of invention of 201110232394 discloses one " crack grouting visualization test device of complex condition ", can carry out multiple Seepage tests under the conditions of miscellaneous, but it can only carry out the seepage tests of horizontal fissure, does not accounts for the rock fracture of different angle Impact on seepage flow, the rock fracture in Practical Project is generally moved towards in difference, need to consider that fracture seepage is in varied situations Gravity couples, if only not meeting practical situation with the natural fissure seepage flow of horizontal fissure seepage simulation different angle, and test Result does not the most have cogency, broken face rock sample deformation performance under different gravity conditions be determine its seepage channel main because of Element;Secondly, the not mentioned transparent material of said apparatus and rock deformation behavior pattern, only transparent material and the deformation performance of rock Consistent, could accurately simulate the seepage channel under the difference pressure of crack;It addition, servo pressurization installation cost is high.
Summary of the invention
Technical problem to be solved in the utility model be to provide a kind of for rock fracture seepage simulation test visual Change seepage flow test device, it is possible to achieve the rough rock crack to different angle carries out visualizing seepage flow under different stress conditions Test and analysis.
For solving above-mentioned technical problem, this utility model be the technical scheme is that a kind of for rock fracture seepage flow The visualization seepage flow test device of simulation test, including the base plate installed on the spinning device, plate upper surface is equipped with band gas The air cushion of pressure table, air cushion is placed with the transparent rocks resin mass consistent with the rock deformation performance of rock sample, base plate surrounding Being equipped with screw rod, the transparent cover clamp that adds is connected with base plate by each screw rod, and screw rod upper end is provided with nut, transparent adds cover clamp It is arranged above camera head;
In rotary apparatus, base plate surrounding is hinged with spherical linkage, and spherical linkage is arranged with telescopic tripod.
Nut and transparent adding, are provided with spring shim between cover clamp.
Air cushion is hoisting air chamber, and maximum resistance to pressure energy is 3 MPas.
Transparent add cover clamp be thickness be armorplate glass or the resin plate of 5-10 millimeter.
The visualization seepage flow test device for the test of rock fracture seepage simulation that this utility model provides, by screwing Nut applies normal stress to the rock fracture of rock sample, utilizes the air gauge on air cushion to measure the square normal stress at rock fracture Size, rotary apparatus realizes arbitrarily changing the function of rock fracture angle, it is possible to achieve incline difference under different stress conditions The rough rock crack at angle carries out visualizing seepage tests and analysis, overcomes the deficiencies in the prior art.
Accompanying drawing explanation
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of this utility model base plate and rotary apparatus.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of visualization seepage flow test device for the test of rock fracture seepage simulation, including Installing base plate 8 on the spinning device, base plate 8 upper surface is equipped with the air cushion 7 of band air gauge 10, air cushion 7 is placed with and rock The transparent rocks resin mass 9 that the rock deformation performance of sample 6 is consistent, base plate 8 surrounding is equipped with screw rod 1, transparent adds cover clamp 4 Being connected with base plate 8 by each screw rod 1, screw rod 1 upper end is provided with nut 2, and the transparent cover clamp 4 that adds is arranged above camera head 11;
In rotary apparatus, base plate 8 surrounding is hinged with spherical linkage 12, and spherical linkage 12 is arranged with telescopic tripod 13。
Nut 2 and transparent adding, are provided with spring shim 3 between cover clamp 4.
Air cushion 7 is hoisting air chamber, and maximum resistance to pressure energy is 3 MPas.
The transparent cover clamp 4 that adds is for armorplate glass that thickness is 5-10 millimeter or resin plate.
Work process of the present utility model is as follows:
First, placing test rock sample 6 on air cushion 7, screw rod 1 is connected with base plate 8 through the transparent cover clamp 4 that adds, passes through The mode of tightening nuts 2 applies normal stress, rock sample 6 and base plate 8 to the rock fracture between rocks resin mass 9 and rock sample 6 Between be provided with air cushion 7, air cushion 7 outwards connects air gauge 10 for measuring the method at rock fracture to stress intensity.
The transparent thickness adding cover clamp 4 is 5-10 millimeter, during for keeping away pressurization nut 2 and transparent add between cover clamp 4 rub Wear wound, be provided with therebetween spring shim 3.
Rock fracture between rocks resin mass 9 and rock sample 6 is formed around layer of silica gel 5 hermetic seal.
Rock sample 6 uses the regular shape that cutting machine cutting surrounding is concordant, it is simple to test assembles.
Resin used by rocks resin mass 9 makes the deformation performance mutual of itself and rock by the content of adjustment sclerosing agent Cause, the more accurate simulation rock deformation impact on seepage channel.
