Abstract
The utility model discloses a kind of suspension proportion Accurate Determining device, comprise picnometer, described picnometer front end is provided with mercury portion or lead button, picnometer there is picnometer scale, gravity-meter is arranged on picnometer rear end, connect knob and connect picnometer and gravity-meter, described gravity-meter is provided with gravity form.Suspension proportion Accurate Determining device of the present utility model can solve Problems existing in above-mentioned test well: picnometer does not produce and fluctuates in suspension, eliminates the disturbance to suspension; The time that suspension put into by picnometer drops to 5 seconds in first 30 seconds from reading, and make the time meeting test condition be increased to 95% from 50%, test findings is closely actual.
Description
Technical field
The utility model relates to device for measuring specific gravity, specifically a kind of suspension proportion Accurate Determining device.
Background technology
Screen analysis test is one of big event of soil test, code requirement: the particle being less than 0.075mm uses hydrometer method to measure each grain group content, and process of the test is: be put in graduated cylinder by 30g dry ground, make 1000cm
3suspension, each 30 times are up and down reciprocatingly stirred along graduated cylinder with stirrer, make even particle distribution in suspension, particle sinks under Gravitative Loads, start the stopwatch record particles sink time simultaneously, particles sink 1 minute, 3 minutes ... measure suspension proportion (picnometer reading) Deng different time, then calculate each grain group content by correlation formula.The order of accuarcy of the suspension proportion measured in test determines the reliability of test findings.
The mensuration process of suspension proportion is: first 30 seconds of reading, refer to that mentioning picnometer slowly puts into suspension with forefinger and mother, when doigte picnometer gravity useless, decontrol picnometer. simply by virtue of feeling that picnometer gravity useless is unscientific, after letting go often, picnometer fluctuates and repeatedly could stablize in suspension, so regulatory requirements reading puts into suspension picnometer in first 30 seconds, reserve the picnometer stable time needed gradually.The theoretical foundation of this test method is that particle sinks along the whole sectional uniform of graduated cylinder, reading puts into suspension picnometer in first 30 seconds, it is very most of that picnometer occupies graduated cylinder cross section, particle is no longer sink along the whole sectional uniform of graduated cylinder, be not inconsistent with testing requirements, and picnometer repeatedly fluctuates in suspension, also destroy the condition that particle evenly sinks under Gravitative Loads.For the particles sink suspension proportion of 1 minute, meet only 30 seconds particles sink time of test condition, other 30 seconds do not meet test condition, therefore, the actual grating situation of test findings and the soil body greatly differs from each other., cause the reason of this situation to be the structure existing defects of picnometer.
Summary of the invention
In order to solve the above-mentioned technical matters existed in prior art, the utility model provides a kind of suspension proportion Accurate Determining device, comprise picnometer, described picnometer front end is provided with mercury portion or lead button, picnometer there is picnometer scale, gravity-meter is arranged on picnometer upper end, connects knob and connects picnometer and gravity-meter, described gravity-meter is provided with gravity form.
Suspension proportion Accurate Determining device of the present utility model can solve Problems existing in above-mentioned test well: picnometer does not produce and fluctuates in suspension, eliminates the disturbance to suspension; The time that suspension put into by picnometer drops to 5 seconds in first 30 seconds from reading, and make the time meeting test condition be increased to 95% from 50%, test findings is closely actual.
Accompanying drawing explanation
Fig. 1 is suspension proportion Accurate Determining apparatus structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, suspension proportion Accurate Determining device of the present utility model, comprise picnometer 1, picnometer 1 front end is provided with mercury portion or lead button 2, picnometer 1 there is picnometer scale 3, gravity-meter 4 is arranged on picnometer 1 upper end, connects knob 5 and connects picnometer 1 and gravity-meter 4, gravity-meter 4 is provided with gravity form 6.
Suspension proportion Accurate Determining device of the present utility model is combined gravity-meter and picnometer, when mentioning gravity-meter, the numerical value of its display is the gravity that picnometer acts on measuring apparatus, during test, picnometer is slowly put into suspension, picnometer is subject to suspension buoyancy, the gravity acting on measuring apparatus reduces, the numerical value of gravity-meter display reduces, and when picnometer is suspended in suspension, the gravity acting on measuring apparatus is decreased to zero, the numerical value of gravity-meter display is zero, now reads picnometer scale reading.
Suspension gravity test step:
One, in graduated cylinder, 1000cm is made
3suspension;
Two, up and down reciprocatingly stir each 30 times with stirrer along graduated cylinder, make even particle distribution in suspension;
Three, take out stirrer and start stopwatch simultaneously;
Four, with forefinger and mother, first 5 seconds of reading, refers to that holding gravity-meter mentions picnometer, slowly puts into suspension by picnometer, observe the measuring apparatus form reading reduced gradually;
Five, when form reading is decreased to zero, suspension proportion (reading picnometer reading) is measured.
