As shown in fig. 1 to 4, the soil sample preparation device for disturbed soil disintegration test provided by the present utility model comprises a base plate 100, a mold 200 and a compaction hammer 300.
The mold 200 has a square inner cavity, two ends of the inner cavity are open, and the inner cavity of the mold 200 is used for accommodating soil for preparing a disturbed soil sample. Specifically, the mold 200 is formed by a plurality of mold units 210 that are arranged around the longitudinal periphery of the inner cavity, wherein one or more mold units 210 are provided with guide holes 220, and adjacent mold units 210 are detachably connected, and one or more mold units 210 are detachably connected with the bottom plate 100.
The compaction hammer 300 includes a ram 310, a guide bar 320, and a connection block 330, the cross section of the ram 310 is matched with the cross section of the cavity of the die 200, the guide bar 320 is located at one side of the ram 310 in the longitudinal direction, the ram 310 is connected with the guide bar 320 through the connection block 330, and the guide bar 320 moves in the guide hole 220 in the axial direction of the guide bar during the movement of the ram 310 in the cavity of the die 200 in the longitudinal direction.
In use, the individual die units 210 are assembled together and the base plate 100 is secured to one end of the die 200 such that the bottom of the cavity is blocked by the base plate 100. Then, the soil body is filled in the inner cavity from the upper part of the inner cavity. Next, the hammer 310 is placed in the cavity while the guide bar 320 is placed in the guide hole 220 as shown in fig. 3. Then, the top of the hammer 310 is knocked, and in the process that the hammer 310 moves downwards closely to the inner cavity, the hammer 310 gradually compacts the soil in the inner cavity on the top of the bottom plate 100, so that a square soil sample is obtained. The guide bar 320 and the guide hole 220 cooperate to prevent the hammer 310 from being displaced during the striking process.
In actual operation, the soil mass with required weight is calculated in advance according to the parameters such as the volume, the density and the like of the soil sample, and when the hammer 310 moves to a specified position along the inner cavity, the required square soil sample can be obtained. Finally, the compaction hammer 300 is removed, the mold units 210 are detached from the base plate 100, and the square soil sample is exposed by detaching the mold units 210 from each other.
