The top plate 1 is connected with the bottom plate 2 through four support columns 10 at the edge, so that the outline of the whole sample preparation demoulding device is formed:
the ascending table 3 and the descending table 4 are connected in series above the supporting column 10 and can move up and down. Circular demoulding ports are respectively arranged on the ascending table 3 and the descending table 4, the diameter of each demoulding port is between the inner diameter and the outer diameter of the die sleeve, and the prepared sample can be demoulded and demoulded from the upper part or the lower part according to requirements.
A force measuring ring 12 and a partial meter 13 are arranged between the ascending table 3 and the descending table 4, and the currently applied pressure value can be read.
The supporting columns 10 play a role of fixing devices, and springs are sleeved outside the supporting columns 10 at the part between the ascending platform 3 and the descending platform 4, so that the ascending platform 3 and the descending platform 4 can be conveniently restored to the original positions in the pressure relief process.

The specifications of the four mechanical jacks 6 are kept consistent, two mechanical jacks on the same layer are arranged on two sides, pressure is conveniently and uniformly conducted, and the four mechanical jacks are connected through the transmission shaft 7, so that the pressure provided by the two mechanical jacks 6 is consistent when an experimenter operates the transmission shaft 7 on one side.
The die sleeve comprises a round die sleeve 14 and a square die sleeve 16, and a round die compaction column 15 and a square die compaction column 17 are correspondingly matched. The mould sleeve and the compaction column are provided with scale indications, when sample preparation is carried out, the mould sleeve is placed on the cover plate 5, and the cover plate 5 is placed on the lower demoulding port 8 of the lower lifting platform to prepare the sample. Under the condition of not using the cover plate 5, one die sleeve can be matched with two compaction columns with the same specification for use, so that the prepared samples are more uniform.
The minimum side length of the cover plate is larger than the diameter of the demoulding opening.
The specific operation mode is as follows:
before sample preparation begins, the cover plate 5 is placed on the lower demolding opening 8, the circular mold sleeve 14 or the square mold sleeve 16 is placed on the cover plate according to sample preparation requirements, a soil sample with a certain mass calculated in advance is added into the circular mold sleeve 14 or the square mold sleeve 16, and then the circular mold compaction column 15 or the square mold compaction column 17 is inserted into the soil sample-added circular mold sleeve 14 or the square mold sleeve 16.
Another way to realize this is to put a round mold compaction column 15 or a square mold compaction column 17 upside down on the lower demolding opening 8, and then to sleeve a round mold sleeve 14 or a square mold sleeve 16 onto the compaction column, at this time, the experimenter needs to lift the mold sleeve to add a soil sample into the mold sleeve, after the soil sample is added, another round mold compaction column 15 or a square mold compaction column 17 with the same specification is inserted from above the round mold sleeve 14 or the square mold sleeve 16.
The upper and lower transmission shafts 7 are shaken to pressurize the mechanical jack 6, so that the upper lifting platform 3 moves downwards, the lower lifting platform 4 moves upwards, the pressurization is stopped when the upper lifting platform 3 contacts the circular mold sleeve 14 or the square mold sleeve 16 inserted at the upper part, and the reading of the dial indicator in the force measuring gauge is adjusted to be zero at the moment. And at the moment, pressurizing and sample preparation can be started, the upper transmission shaft 7 can be shaken to apply certain pressure, then the lower transmission shaft 7 is shaken to pressurize, the upper pressure and the lower pressure are kept consistent, the increment of the dial indicator 13 is equal, the pressurizing operation is repeated until the pre-calculated scale of the mold or the certain scale of the dial indicator 13 is reached, and the soil body remodeling sample pressing process is completed.
After the sample is pressed, the sample is kept for 3 to 5 minutes under the current pressure unchanged state, so that the sample is formed. Then the pressure relief valve of the mechanical jack 6 is rotated to relieve the pressure. At this time, the upper and lower stages 3 and 4 are resiliently returned to the original positions under the springs 11 externally fitted to the support columns 10.
When demoulding is carried out at the upper demoulding opening, the pressed sample and the round mould sleeve 14 or the square mould sleeve 16 which is covered outside the sample are inverted, the round mould compaction column 15 or the square mould compaction column 17 are turned upside down, namely the opening of the round mould sleeve 14 or the square mould sleeve 16 is upward and is aligned with the upper demoulding opening 9, at this time, the upper transmission shaft 7 and the lower transmission shaft 7 are shaken to pressurize, so that the pressure applied by the upper transmission shaft is larger for taking out the sample conveniently, and the pressurization is continuously carried out until the sample is completely released from the round mould sleeve 14 or the square mould sleeve 16.
In another embodiment, the mold is removed by first removing the circular mold sleeve 14 or the square mold sleeve 16 from one side and then removing the mold according to the above operation. When the lower demolding opening 8 is demolded, the cover plate 5 at the lower demolding opening 8 is taken down firstly, then the opening of the circular mold sleeve 14 or the square mold sleeve 16 faces downwards and is aligned with the lower demolding opening 8, pressurization is continuously carried out, when a sample is rapidly demolded, a tester should lift the sample by hand so as to prevent the sample from falling off, and finally the sample is completely demolded.
