(2) air-dry as needed for the admaic earth dry density of design and the soil body sample 5 of moisture content calculating one sample preparation pipe of preparation
The quality of soil and amount of water, soil are placed in after uniformly being sprayed with aerosol apparatus layering in plastic tub, are tightened with plastic foil, moistening one daytime
At night, make porous media uniform.
(3) adopt small-sized ramming device to prepare soil body sample 5, circadian for moistening soil sample all poured into sample preparation pipe 3 in four times,
Often pour into once i.e. with small-sized ramming device hit real (first will be even for soil sample surface layer stand, then will be placed on it for small-sized ramming device base 1, push away
Dynamic hammer 2 hits real sample until sample face reaches predetermined height), next layer first should carry out " plucking " to surface layer before hitting reality (protects
Card soil body sample 5 occurs without lamination), it is to be particularly noted that last layer of soil sample is hit in real time, should be first by outer extension 4
It is enclosed within sample preparation pipe 3, then the positive activity that hits that soil sample is poured into before repeating in sample preparation pipe 3 (avoids loose soil sample to trickle down sample preparation
Outside pipe 3).
(4) seal approach (see figure 3) is simultaneously carried out in soil body sample 5 center for preparing thermal probe 6 inserting step (3),
Finally the device connecting is placed on the stainless steel stent 9 in GDJS 7 maintenance 24 at room temperature
Hour.
(5) repeat step (1) ~ (4), prepare same batch sample respectively, carry out the following heat setting under thermic load operating mode
Physical property measurement is tested.
(6) pass through the temperature control programing function of GDJS 7, high/low temperature cyclic damp heat test is set
Case 7 press following thermic load run (, in formulatFor the temperature in proof box 7
Degree, unit be DEG C,tFor run time, unit ish .), this thermic load operating mode describes temperature and first increases linearly over time
Long, keep temperature-constant operation when temperature reaches a certain setting maximum.Thermic load operating mode is run high/low temperature after setting completed and is handed over
Become moisture-heat test-box 7.
