Description
Technical field
This utility model relates to hydraulic structure laboratory simulation technical field, particularly relates to a kind of method simulating reservoir dam seepage proof curtain and the test structure model of the method employing.
Background technology
The most large medium-size station of China and reservoir have run more than 20 years, and the most more project is gone into operation successively and is completed.Seepage proof curtain is the crucial component of reservoir dam impervious leakage-stopping, and seepage proof curtain is chronically under the effect of high pressure permeability current, and hydro-geochemical environment is complicated, and seepage proof curtain will continue to suffer from corroding and aging decay.To non-karst area, seepage of dam is based on fissurity seepage；To karst area, seepage field is increasingly complex, has karst and fissurity seepage feature concurrently.
Grout curtain its essence is that cement grout is in high pressure effect retrofilling karst or the process in crack.Actual geologic body is huge, material the Nomenclature Composition and Structure of Complexes complex.Owing to actual geologic body is huge, the most only theory analysis and actual application, also there is no the formation about seepage proof curtain and change procedure analog data, the impact Essential Analysis foundation to seepage proof curtain.
Utility model content
The purpose of this utility model is, it is provided that a kind of test model simulating reservoir dam seepage proof curtain.For providing the data foundation close to reality in the formation of laboratory simulation reservoir dam seepage proof curtain and change.
The technical solution of the utility model is as follows:
A kind of method simulating reservoir dam seepage proof curtain, it makes a casing with one block of rubber or metal material, and a high-pressure intake pipe it is provided with 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 serosity of curtain body does not condenses, 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 to enter curtain body from rear bundle hole；After concrete coagulation, after maintenance a period of time, high-pressure water pipe connecting high-pressure hydraulic pump, the data observed on water pressure gauge regulate required hydraulic pressure, thus draw the osmotic value of current in curtain；The water flowed out is carried out physics and chemical analysis, draws content and pH value, electrical conductivity and the temperature field of SO42-, HCO3-, Ca2+, Mg2+ as evaluation points.
For realizing said method, this utility model have employed the model of such a simulation reservoir dam seepage proof curtain, and it includes the casing being 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 additionally provided with water pressure gauge.
Technique effect of the present utility model is as follows:
Test model of the present utility model can simulate in laboratory can be with the seepage proof curtain model of geological structure body of the reservoir dam of practical operation.Seepage discharge and osmotic pressure variation characteristic and the injuring relation with curtain thereof of curtain can be drawn by test, can also be by the current oozed out in test model, analyze water quality, drawing the isoionic content of SO42-, HCO3-, Ca2+, Mg2+ and the data such as pH value, electrical conductivity in seepage proof curtain body, formation and change for seepage proof curtain provide the data foundation close to reality.
Accompanying drawing explanation
Fig. 1 is apparatus structure schematic diagram of the present utility model.
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
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Embodiment 1:
As it is shown in figure 1, device of the present utility model includes the casing 1 being made up of rubber or metal material, casing 1 is filled 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 additionally provided with water pressure gauge 6.
This device can simulate the curtain body whole process in reservoir dam in seepage proof curtain.When being embodied as, looking 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, high-pressure intake pipe 3 is additionally provided with water pressure gauge 6.The curtain that seepage proof curtain substantially cement liquid is formed at high pressure effect retrofilling karst or crack.In casing 1, fill curtain body, when the serosity of curtain body does not condenses, stretch in high-pressure water pipe 3 with elongated reinforcing bar, the Plastic cap 5 of high-pressure water pipe 3 termination is broken, enable water to enter curtain body from rear bundle hole.When the effect of Plastic cap 5 is to prevent casting concrete, concrete enters high-pressure water pipe and is blocked by the mouth of pipe, again by pricking a hole after elongated reinforcing bar after only pouring.After concrete coagulation, after maintenance a period of time, high-pressure water pipe 3 connecting high-pressure hydraulic pump, the data observed 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 chemical analysis, draws the primary evaluation factor such as content and pH value, electrical conductivity, temperature field of SO42-, HCO3-, Ca2+, Mg2+.
Certainly, being more than concrete exemplary applications of the present utility model, this utility model also has the technical scheme that other embodiment, all employing equivalents or equivalent transformation are formed, within all falling within the protection domain required by this utility model.
