Please refer to Fig. 3, forcing pump 6 is made of shell 601, cylinder body 602, piston 603, piston rod 604, linear electric motors 605, cylinder body 602 is installed in the shell 601, piston 603 is installed in the inner chamber of cylinder body 602, the inner of piston rod 604 is connected on the piston 603, the outer end of piston rod 604 is connected with linear electric motors 605, and linear electric motors 605 are connected with electronic controller 9 by lead.
The panel of electronic controller 9 is provided with LCDs, options button, power interface, power switch, and electronic controller is made up of data bus driver, display screen interface circuit, keyboard interface circuit, RS232 interface circuit, sample circuit, microprocessor, storer, rechargeable battery.
This instrument can be tested air concrete air pressure attenuation rate and water are penetrated into volume in the concrete, tests water outlet respectively to concrete perviousness and concrete water absorptivity under the constant voltage of 500mbar and 200mbar.
During use, base ring is sticked with glue on the surface that is connected on concrete 18, base ring 4 isolates the area of a diameter 50mm.Pass through options button then, select test approaches, the options button of the testing permeability correspondence of air penetration property testing, water absorptivity test, water is respectively: K1, K2, K3, two other button K4, K5 on the guidance panel of electronic controller 9 are provided with key and on ﹠ off switch.
When carrying out the air penetration property testing, press options button K1 earlier, the microprocessor of electronic controller inside is according to the setting of internal processes, close No. two, No. three, No. four solenoid valves 12,13,14, open solenoid valve 11 No. one, the operator adds air injection with syringe 17 in wireway 203, the air pressure of test inside, storehouse is increased, by the instrumental observation number pressure on electronic controller 9 panels, when number pressure reaches 500mbar, the microprocessor of electronic controller 9 inside receives the pressure signal of pressure transducer 15 passbacks, closes solenoid valve 11 automatically No. one, and test begins to carry out automatically from this constantly.
Pressure air in the test storehouse dissipates on concrete surface gradually, the wireway 203 interior pressure that are connected with the test storehouse will reduce, the microprocessor of electronic controller 9 inside is gathered the signal that pressure transducer 15 feeds back in real time, monitor the decay of air pressure, the per minute collection is also stored force value one time, continue 15 minutes, too fast if air reduces, pressure may reduce to zero in 15 minutes.In this case, test will stop automatically, and data are stored.The operator needn't do any operation in whole process.After finishing in 15 minutes, or pressure is when reducing to the lowest limit, and the hummer of electronic controller 9 inside sounds, and prompting operation person's test is finished.
Therefore the decay mode of pressure is natural logarithm rather than linear mode, if test continues 15 minutes, with the index of the linear attenuation curve between the 5th minute and the 15th minute as air permeability, the Ln/min of unit; If pressure vanishing before 15 minutes, data were calculated constantly from on-test, determine slope.
The water absorptivity test can be done in the same position of a last test, but at least should be at interval more than one hour, and the water absorptivity test is finished automatically.
When carrying out the water absorptivity test, press options button K2 earlier, the microprocessor of electronic controller 9 inside is according to the setting of program, open solenoid valve 11,12,13,14 No. one, No. two, No. three, No. four, this moment pressure transducer 15 automatic clears, micro pump 5 begins to start, by the water filling in the test storehouse of left water inlet pipe 201, along with the filling of water, the air in the test storehouse is discharged by wireway 203.In the process of filled with water in the test storehouse, right water inlet pipe 202 also is conducting, so has also filled with water in cylinder body 602 inner chambers of forcing pump 6.After the filled with water of test storehouse, micro pump 5 quits work under the control of microprocessor automatically, then, microprocessor cuts out solenoid valve 11,12,13 No. one, No. two, No. three, export control signal simultaneously and give forcing pump interior linear electric motors 605, linear electric motors 605 work, the accurately displacement of control piston bar 604, by piston 603 water inlet pipe 202 pressurizations to the right, hydraulic pressure is increased to the above 200mbar of atmospheric pressure in the test storehouse.The test beginning, at this moment press water can be thought by the absorption of the kapillary of concrete surface rather than owing to pressure flows.After water was absorbed by the concrete surface kapillary, the hydraulic pressure of the inside, test storehouse had a declining tendency; Therefore to maintain the above 200mbar of atmospheric pressure to hydraulic pressure by forcing pump 6.In 15 minutes of test, the water injection rate of a forcing pump 6 in the test storehouse measured and stored to the microprocessor per minute, note the water absorbing capacity of test period, the square root of the water yield and time is linear relationship (though this relation is to rely on typical concrete test, can use in nearly all engineering reality).
The square root relationship of the water yield and time converts figure to graphic software, and the oblique line that reflects on the figure is as absorptive index, and unit is: cube m/min.Data between the 5th minute and 15 minutes of figure are as valid data, thereby mistake is minimized.Be used for calculating the water-intake rate of initial surface in 10 minutes the 10th minute to the 11st minute interval data, unit is: milliliter/every square metre/per second.When test was finished, data were stored in the storer.
Seepage of water test and water absorptivity test are same processes, and just test pressure is 500mbar, during test, carry out another position on concrete surface, not disturb mutually, the system pressure that meets the requirements of 500mbar should be finished in 1 minute, can not be above 2 minutes.If surpass 2 minutes, test should stop, and water permeability test and water absorptivity test are same processes.Hydraulic pressure is raised to 500mbar in this test, and infiltrating the water yield of concrete surface and the ratio of the square root of time is linear relationship.Therefore, the 5th minute to the 15th minute of water absorptivity test, the oblique line of water absorbing capacity and time square root ratio can be used as the index of the testing permeability of water, and the former causes the seepage of water, the latter for concrete surface capillaries absorbs water be the variation of hydraulic pressure decline causing slope.
