Bottom portion is built, the bolt card for filling bottom portion is fixed in J-type neck with nut, groove profile funnel and is filled after case fixes, groove
Type funnel left and right sides are with filling case sand removing hole face.Support is made up of six roots of sensation quadrangular and cuboid bottom plate, the rib of the six roots of sensation four
Post is just withstood on the flat board for filling case front and rear sides, is filled after case and groove profile funnel be connected, is placed on support, hopper base
Portion is hanging.
Determine to fill case by the volume of the known sand that fills case internal diameter size and graduated scale, can fill as needed
The height of sand loaded in advance is needed, cushion cap and plane steel wire can determine the particular location of sand height, and auxiliary is in advance
Filling.Fill sand and may be selected to fill sand removing hole direct filling or groove profile funnel at left and right sides of case and fill.
Compared with prior art, the beneficial effects of the utility model are：
It can be used to fill the sand for determining volume in the experiment of soil arching effect research model in Piled Embankments, aid in sand
Soil fills operation, is convenient for the placement in layers of sand, and controllable sand fills speed, slowly can equably fill sand, make
In model test sand fill link operation it is easier, make bulk testing easier, accurate, it is workable, structure
Simply, it is readily produced, it is easy to utilize.
