Add water, water can not be added in infiltration process, the negative pressure in water storage cavity 11 can be changed if water is added in infiltration process.
4th, when infiltrating 2 no water of disk in the case that test device is vacantly placed vertically and spilling, can start to test.
Regulate negative pressure value.3 position in the installation through-hole of rubber stopper 103 of mobile regulation negative pressure regulation pipe, regulation are negative
The spacing of regulation pipe 3 and the bottom of negative pressure adjusting cavity 12 is pressed, makes in negative pressure adjusting cavity 12 that the water surface is corresponding with negative pressure regulation pipe 3 to be born
Pressure value scale maintains an equal level.If negative pressure regulation pipe 3 moves difficulty, some vacuum profits can be smeared on the tube wall of negative pressure regulation pipe 3
Lubricating oil.Because the Infiltration speed of Different Soil is different, the change of measure volume/time is just relatively difficult, particularly
The very fast soil types of infiltration rate as sand.It is therefore desirable to according to the soil types of measure adjust negative pressure value with
Infiltration process is preferably adapted to, general soil hole is bigger, and the negative pressure value of regulation is bigger, and soil aperture is smaller, the negative pressure of regulation
Value is also smaller.For majority of case, 2cm negative pressure value is just right.The infiltration rate of sand is due to quickly, negative pressure
Value 6cm is proper；And infiltrated for degree of packing height for slow soil, it is proposed that use 0.5cm negative pressure value.Above-mentioned regulation
Negative pressure value size can obtain according to measurement experience, or be obtained by test measurement, i.e., first make to infiltrate the fitting soil of disk 2,
According to the suitable negative pressure value of infiltration process de-regulation, a suitable negative pressure value is finally obtained.It is emphasized that：Surveyed in single
, cannot intermediate regulations once negative pressure value is set during amount.
After regulating negative pressure value, Level tune is carried out using level meter 9 and adjustable telescopic foot lever 71, makes circle in level meter 9
Point is located at center.Pay attention to：In horizontal process is adjusted, it should try one's best and reduce the water that test device is not up to level and infiltrated
Amount.Now negative pressure value should be adjusted to minimum, correct position is transferred to after level, then by negative pressure value.
Water when starting is determined by measuring instrument, during Infiltration, determined and recorded once at interval of 10 seconds
Water.After stabilization is infiltrated（The water of at least 10 times measure is equal）, stop measure and record, measuring instrument preserves data
To chip, the result finally drawn is shown over the display.After measurement terminates, the zero setting key of measuring instrument is pressed, measurement can be made
Instrument recovers original test mode, can be tested next time.For the different speed infiltrated, said determination simultaneously records water
Interval time is according to depending on concrete condition.
Described above is only preferred embodiment of the present utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment.To those of ordinary skill in the art, the gained under the premise of the utility model technical concept is not departed from
To modifications and variations also should be regarded as the scope of protection of the utility model.
