Cube manipulated soil preparation of soil sample step
It prepares soil sample: taking suitable soil sample, hammer sieve that is broken and crossing 0.5mm into shape, be then placed in 105 DEG C -110 DEG C of baking oven
It is dried to eight hours or more, then moisture content as requested configures a certain amount of pattern.Then the stewing material of isolation air sealing for 24 hours with
On.
Preparation soil sample: the soil sample of a certain amount of quality is weighed first.Then ejector dozer is adjusted into native frame bottom, at
It native frame, ejector dozer and hits the lower part of real hand hammer and smears certain vaseline, vaseline plays lubricating action.Then at native frame
The soil sample (divide three layers and hit reality) that one third weighs up, hand hammer is placed in soil sample, while guide rod is placed on guide rod and is fixed
On frame, guide rod lower part and real hand hammer upper contact is hit at this time, then lifting weight makes weight free-falling.It is dry here according to soil sample
The difference of density selects different striking times.Then it casts anchor to soil sample, then the soil sample of falling one third, repeats aforesaid operations.
It hits after the completion of reality, adjusts soil sample size control, soil sample size control is made to be transferred to ruler identical with horizontal size
It is very little.It rotates soil-shifting bolt and releases soil sample, when bolt rotation is motionless, it was demonstrated that soil sample has reached estimated size.It is naked to cut off top
The soil sample of dew, then adjusting soil sample size control again releases control, then rotates bolt, is pushed out soil sample completely.
The cube soil sample prepared should be wrapped up with film to completely cut off itself and external water_air exchange rapidly, and at normal temperature
It stands 2d or more and reaches the water balance inside soil sample.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
