Abstract
The invention discloses a method and model for simulated testing an antiseepage curtain between concrete and a bedrock. A regularly-shaped bedrock is provided, and one side of the bedrock is chiseled to be rough. A high pressure water pipe with a plastic bulkhead is placed on the center of the rough surface of the bedrock, and a stirred concrete layer is poured on the rough side of the bedrock to totally cover the high pressure water pipe. An elongated steel bar is extended in the high pressure water pipe to poke the plastic bulkhead on the other end of the high pressure water pipe so as to form a hole when the concrete is not yet cured, so that water can seep into the contact surface between the bedrock and the concrete layer from the hole. After the concrete is normally cured, the high pressure water pipe is connected with a high pressure water pump. The water pressure needed is adjusted according to the data on a water pressure gauge. In this way, a penetration value of water flow in an antiseepage curtain when the curtain makes contact with a bedrock can be obtained through simulated testing means, and the relation between the seepage flow of the curtain and penetration pressure variation characteristic and the damage of the curtain can be obtained.

Background technology
the most large medium-size station of China and reservoir have run and have exceeded Two decades years, also have more project go into operation successively and be completed in recent years.Seepage proof curtain is the crucial component of reservoir dam impervious leakage-stopping, and under seepage proof curtain is in the effect of high-pressure osmosis current for a long time, hydro-geochemical environment is complicated, and seepage proof curtain is corroded continuing and aging decay.To non-karst area, seepage of dam is based on fissurity seepage; To karst area, seepage field is more complicated, has karst and fissurity seepage feature concurrently.
grout curtain its essence is the process of cement grout in High Pressure retrofilling karst or crack.Actual geologic body is huge, material the Nomenclature Composition and Structure of Complexes complex.Because the geologic body of reality is huge, only have theoretical analysis and practical application at present, also there is no the formation about seepage proof curtain and change procedure simulated data, affect the Essential Analysis foundation to seepage proof curtain.
Summary of the invention
the object of the invention is to, test method and the model of seepage proof curtain between a kind of simulation concrete and basement rock are provided, for the formation of seepage proof curtain and change provide the data foundation close to reality between laboratory simulation concrete and basement rock, thus overcome the deficiencies in the prior art.
technical scheme of the present invention is achieved in that
between a kind of simulation concrete of the present invention and basement rock, the test method of seepage proof curtain is, when the whole process simulation that the method curtain in seepage proof curtain contacts with basement rock is tested, look for the basement rock that a piece comparatively upright in advance, to wherein one side dabbing, high-pressure water pipe with Plastic cap is placed on the position in the middle of basement rock roughened surface, then the concrete layer of mix is cast on the basement rock of dabbing, and high-pressure water pipe is covered completely, can simulate between concrete layer and basement rock like this and form seepage proof curtain; When normal concrete does not condense, stretch in high-pressure water pipe with elongated reinforcing bar and the Plastic cap of high-pressure water pipe other end is broken, after forming one, prick hole, enable water enter the surface of contact of basement rock and concrete layer from rear bundle hole; After normal concrete condensation, high-pressure water pipe is connected high-pressure hydraulic pump, the data of observing on water pressure gauge regulate required hydraulic pressure, the osmotic value of current in curtain when so namely showing that in seepage proof curtain, curtain contacts with basement rock by the mode of this simulation test, and the seepage flow of curtain and seepage pressure variation characteristic and the injuring relation with curtain thereof can be drawn.
between the of the present invention a kind of simulation concrete built according to said method and basement rock, the test model of seepage proof curtain is, this test model comprises basement rock, basement rock one side is provided with concrete layer, and be embedded with high-pressure water pipe at the surface of contact of basement rock and concrete layer, high-pressure water pipe is provided with water pressure gauge.
in aforesaid experimental model, described high-pressure water pipe one end is provided with Plastic cap, and one end that high-pressure water pipe is provided with Plastic cap is positioned at the central authorities of basement rock and concrete layer surface of contact, and Plastic cap is provided with rear bundle hole.
in aforesaid experimental model, described basement rock and concrete layer surface of contact are that hair side contacts.
owing to have employed technique scheme, compared with prior art, the present invention can simulate in laboratory can seepage proof curtain model of geological structure body between the concrete of practical operation and basement rock in the present invention.By testing the seepage flow and seepage pressure variation characteristic and the injuring relation with curtain thereof that can draw curtain, also can by the current oozed out in test model, analyze water quality, draw the data such as the isoionic content of SO42-, HCO3-, Ca2+, Mg2+ and pH value, conductivity, temperature field in seepage proof curtain body, for the formation of seepage proof curtain and change provide the data foundation close to reality.For between laboratory simulation concrete and basement rock, the formation of seepage proof curtain and change provide the data foundation close to reality.

Embodiment
below in conjunction with drawings and Examples, the present invention is described in further detail, but not as any limitation of the invention.
between a kind of simulation concrete of the present invention and basement rock, the test method of seepage proof curtain is, as shown in Figure 1, the method is that curtain contacts with basement rock in seepage proof curtain whole process simulation is when testing, look for the basement rock 2 that a piece comparatively upright in advance, to wherein one side dabbing, high-pressure water pipe 3 with Plastic cap 5 is placed on the position in the middle of basement rock roughened surface, then the concrete layer 1 of mix is cast on the basement rock 2 of dabbing, and high-pressure water pipe 3 is covered completely, can simulate between concrete layer 1 and basement rock 2 like this and form seepage proof curtain; When normal concrete does not condense, stretch in high-pressure water pipe 3 with elongated reinforcing bar and the Plastic cap 5 of high-pressure water pipe 3 other end is broken, form one and prick hole 7 afterwards, enable water enter the surface of contact 6 of basement rock and concrete layer from rear bundle hole 7; After normal concrete condensation, high-pressure water pipe 3 is connected high-pressure hydraulic pump, the data of observing on water pressure gauge 4 regulate required hydraulic pressure, the osmotic value of current in curtain when so namely showing that in seepage proof curtain, curtain contacts with basement rock by the mode of this simulation test, and the seepage flow of curtain and seepage pressure variation characteristic and the injuring relation with curtain thereof can be drawn.
the test model of seepage proof curtain between the of the present invention a kind of simulation concrete built according to said method and basement rock, as shown in Figure 1, this test model comprises basement rock 2, basement rock one side is provided with concrete layer 1, be embedded with high-pressure water pipe 3 at the surface of contact 6 of basement rock and concrete layer, high-pressure water pipe is provided with water pressure gauge 4.High-pressure water pipe 3 one end is provided with Plastic cap 5, and one end that high-pressure water pipe is provided with Plastic cap is positioned at the central authorities of basement rock 2 and concrete layer 1 surface of contact, and Plastic cap is provided with rear bundle hole 7.Basement rock with concrete layer surface of contact 6 for hair side contacts.
