Description
Technical field
the utility model relates to the test model of seepage proof curtain between a kind of simulation concrete and basement rock, belongs to seepage control of dam curtain technique field.
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.
Utility model content
the purpose of this utility model is, the test model of seepage proof curtain between a kind of simulation concrete and basement rock is 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.
the technical solution of the utility model is achieved in that
between a kind of simulation concrete of the present utility model and basement rock, the test model of seepage proof curtain is that this test model comprises basement rock, and 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 utility model can simulate in laboratory can seepage proof curtain model of geological structure body between the concrete of practical operation and basement rock for the utility model.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.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model.
mark in accompanying drawing: 1-concrete layer; 2-basement rock; 3-high-pressure water pipe; 4-water pressure gauge; 5-Plastic cap; The surface of contact of 6-basement rock and concrete layer; Hole is pricked after 7-.
Embodiment
below in conjunction with drawings and Examples, the utility model is described in further detail, but not as to any restriction of the present utility model.
the utility model is constructed by the test method of seepage proof curtain between following a kind of simulation concrete and basement rock, 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 is covered completely, 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, water is enable to 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 utility model 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.
Embodiment
this can simulate the whole process that in seepage proof curtain, curtain contacts with basement rock such as shown in Fig. 1.Look for the basement rock 2 that a piece comparatively upright, 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 is covered completely, 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.The effect of Plastic cap 5 is that when preventing casting concrete, concrete enters high-pressure water pipe and blocked by the mouth of pipe, again by pricking a hole after elongated reinforcing bar after only building.After normal concrete condensation, after maintenance a period of time, high-pressure water pipe 3 is connected high-pressure hydraulic pump, the data of observing on water pressure gauge 4 regulate required hydraulic pressure, thus draw the osmotic value of current in curtain.The water flowed out can carry out physics and chemistry analysis, draws the primary evaluation factors such as the content of SO42-, HCO3-, Ca2+, Mg2+ and pH value, conductivity, temperature field.
