Description
Technical field
The utility model relates to the engineer geological prospecting measuring technique, carries out aquifer original position permeability device for quick testing in particularly a kind of boring (measuring well)
Background technology
The transmission coefficient of determining rock (soil) body is one of vital task of engineering investigations such as water power water conservancy.It is that hydrogeology, engineering geologic condition analysis, the safety monitoring assessment of (water conservancy project) building foundation and foundation are handled indispensable quantitative parameter.Up to now, the main means of domestic mensuration hydrogeological parameter are the pumping test method, and other also has water injection test method, water level restoring method etc.
Commonplace abroad to the hydrogeological Study of test method of holing, method is more, especially in engineering is used, because the representative scope of parameter and the precision that often need to understand are different from water resources assessment, general wish by simple and easy, field trial is obtained the hydrogeological parameter of rock (soil) body fast, wherein to measure the transmission coefficient application comparatively extensive for quick little water test (Slugtest) method of taking out (notes) water with moment in boring.This test method is to cause that by the increase of the instantaneous small water yield in the measuring well (or minimizing) the measuring well water level is over time to determine a kind of simple and easy method of aquifer permeability parameter.Its measurement mechanism comprises data collecting system, sensor and water pump etc.During parameter measurement, utilize water pump moment in measuring well to take out (notes) a certain amount of water body, make the well water position rise suddenly or descend, change procedure by sensor and position rising of data collecting system record WIH or decline, in conjunction with other geologic datas of measuring the place and the data of measuring well, through calculating the transmission coefficient that just can obtain measuring well.
This major defect of taking out (notes) water gaging method is, exigent hydrogeological fringe conditions, and the testing regulation complexity, bothersome time-consuming, the experimentation cost height, precision is low.Especially in the deep covering layer boring under low water stage, the high water yield situation routine take out (notes) wetting system and often be difficult to meet the demands, practical application is very difficult.
The utility model content
Technical problem to be solved in the utility model is exactly the osmotic coefficient measurement method practical operation inconvenience at prior art, the process complexity, and the shortcoming that certainty of measurement is low provides a kind of device that the transmission coefficient measurement is carried out in the head free oscillation in the well that utilizes.
The utility model solve the technical problem, and the technical scheme of employing is, the transmission coefficient measurement mechanism comprises data collecting system, sensor, and described sensor places measuring well to be connected with data collecting system by cable; It is characterized in that, also comprise the head activating system, described head activating system is connected with measuring well;
Concrete is, described head activating system is connected with measuring well by seal cover, and described head activating system is made of air compressor;
Further be on the described seal cover bleeder valve to be installed.
The beneficial effects of the utility model are, do not need special taking out (notes) wetting system, have simplified measuring process, have improved certainty of measurement, have enlarged range of application.
Description of drawings
Fig. 1 is the structural representation of embodiment.
The specific embodiment
Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail.
The utility model improves measurement mechanism according to the basic principle of little water test, and the utilized head activating system encourages the water body in the measuring well, makes it produce vibration.By gathering the oscillation data of water body in the measuring well, calculate transmission coefficient.
Embodiment
As shown in Figure 1, the transmission coefficient measurement mechanism that this is routine comprises data collecting system 1, sensor 2.This routine head activating system is made of air compressor 3, and air compressor 3 is connected with the end of seal cover 50 with measuring well 5 through piping 30.50 pairs of measuring wells 5 of seal cover seal, and its inner space is hedged off from the outer world, and bleeder valve 4 is installed on the seal cover 50.Sensor 2 places measuring well among Fig. 1, is submerged in that the water surface is following (usually apart from the water surface 0.5～10m), to be connected with data collecting system 1 by cable 10.
When measuring, start air compressor 3, slowly open the barostat (not shown) and measuring well is forced into the water surface reaches the selected degree of depth.Usually require satisfying the as far as possible little pressure of use on the basis of test conditions, to reduce the data noise.After being pressurized to the selected degree of depth, open bleeder valve 4 rapidly to excite water body vibration, on-test.Approximately after gathering active data about 5 minutes (can set as required), promptly finish shaking test.After a test period finishes, according to the osjcillating ode figure that shows on the data collecting system 1, determine whether test this time needs to preserve, be saved in flash disk if desired,, select " preservation external memory " at interface of main menu, " determine " to get final product, if dissatisfied to experimental data, but retest, and the experimental data in data collecting system 1 internal memory can empty automatically.Experimental data can access inquiry to the historical data of external memory after preserving and finishing.According to the stratum, hydrogeological conditions in test location size in conjunction with structure, aquifer type, test method and the damped coefficient of test hole, reasonably select design formulas, the infiltration that just can obtain this measuring well is.
Claims (3)
