Abstract
The invention discloses a method and model for simulating an impervious curtain of a reservoir dam. The model comprises a box (1), a curtain body (2), a high-pressure water inlet pipe (3) and a water outlet pipe (4). A plastic plug (5) and a water pressure gauge (6) are arranged on the high-pressure water pipe. The experimental model can simulate an impervious curtain geologic body model, capable of being actually operated, of the reservoir dam in a laboratory. The change features of the seepage flow and seepage pressure of the curtain and the damage relation between the change features and the curtain can be obtained through experiments, water quality can be analyzed through seeping water flow in the experimental model, the content, Ph value, conductivity and other data of SO42-, HCO3-, Ca2+, Mg2+ and other ions in the impervious curtain body can be obtained, and data bases close to the reality are provided for forming and changing of the impervious curtain.
Description
Technical field
The present invention relates to hydraulic structure laboratory simulation technical field, particularly relate to a kind of simulate reservoir seepage control of dam curtain method and the test structure model that adopts of the method.
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.
Curtain grouting 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 theory analysis and practical application at present, also there is no the formation about seepage proof curtain and change procedure analogue data, affect the Essential Analysis foundation to seepage proof curtain.
Summary of the invention
The object of the invention is to, a kind of test model of simulating reservoir seepage control of dam curtain is provided.For providing the data foundation close to reality in the formation of laboratory simulation reservoir dam seepage proof curtain and change.
Technical scheme of the present invention is as follows:
A kind of method simulating reservoir seepage control of dam curtain, it makes a casing with one block of rubber or metal material, and be provided with a high-pressure intake pipe in the bottom of casing, the top of casing is provided with outlet pipe, in casing, fill the curtain body of cement placement, when the slurries of curtain body do not condense, stretch to from bottom to top in high-pressure water pipe with elongated reinforcing bar, the Plastic cap of high-pressure water pipe termination is broken, enables press water enter curtain body from rear bundle hole; After concrete coagulation, after maintenance a period of time, high-pressure water pipe is connected high-pressure hydraulic pump, the data of observing on water pressure gauge regulate required hydraulic pressure, thus draw the osmotic value of current in curtain; Physics and chemistry analysis is carried out to the water flowed out, draws the content as SO42-, HCO3-, Ca2+, Mg2+ of evaluation points and pH value, electrical conductivity and thermal field.
For realizing said method, present invention employs a kind of like this model of simulating reservoir seepage control of dam curtain, it comprises the casing be made up of rubber or metal material, fills the curtain body of cement placement in casing; The bottom of casing is provided with high-pressure intake pipe, and the top of casing is provided with outlet pipe, and the top of high-pressure intake pipe is provided with Plastic cap; High-pressure intake pipe is also provided with water pressure gauge.
Technique effect of the present invention is as follows:
Test model of the present invention can simulate in laboratory can the seepage proof curtain model of geological structure body of reservoir dam of practical operation.By testing the seepage discharge and osmotic 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 isoionic content of SO42-, HCO3-, Ca2+, Mg2+ and the data such as pH value, electrical conductivity in seepage proof curtain body, for the formation of seepage proof curtain and change provide the data foundation close to reality.

Description of reference numerals: 1-casing, 2-curtain body, 3-high-pressure intake pipe, 4-outlet pipe, 5-Plastic cap, 6-water pressure gauge.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
Embodiment 1:
As shown in Figure 1, the inventive system comprises the casing 1 be made up of rubber or metal material, in casing 1, fill the curtain body 2 of cement placement; The bottom of casing 1 is provided with high-pressure intake pipe 3, and the top of casing 1 is provided with outlet pipe 4, and the top of high-pressure intake pipe 3 is provided with Plastic cap 5; High-pressure intake pipe 3 is also provided with water pressure gauge 6.
This device can simulate the whole process of curtain body in reservoir dam in seepage proof curtain.During concrete enforcement, look for the casing 1 that one block of rubber or metal material are made, and be provided with high-pressure intake pipe 3 and outlet pipe 4 at the two ends of casing 1, high-pressure water pipe 3 termination is provided with Plastic cap 5, and high-pressure intake pipe 3 is also provided with water pressure gauge 6.Seepage proof curtain is in fact the curtain that cement liquid is formed at High Pressure retrofilling karst or crack.In casing 1, fill curtain body, when the slurries of curtain body do not condense, stretch in high-pressure water pipe 3 with elongated reinforcing bar, the Plastic cap 5 of high-pressure water pipe 3 termination is broken, water is entered curtain body from rear bundle hole.The effect of Plastic cap 5 is that when preventing concreting, 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 concrete coagulation, 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 6 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, electrical conductivity, thermal field.
Certainly, more than just embody rule example of the present invention, the technical scheme that the present invention also has other embodiment, all employings to be equal to replacement or equivalent transformation to be formed, all drops within protection domain of the presently claimed invention.
