Soil compaction and its application

The present invention relates to a soil compaction and its application, the present invention includes a base, hammer, hit-like tube, a platen and platen bolt, characterized in that: said hit by an outer cylindrical casing-like, ring-like hit, the casing and clamp composition, wherein: barrel-like hit strike layer from bottom to top of the sample loop, the outer casing, the outer layer of the outer casing, the outer casing is provided with at least two fastening the upper and lower clamp; said outer casing and the ring-like hit at least two arcuate plates formed from a stitching circle, consistent with the inner diameter of the casing ring-like hit; strike-like base with a matching concave cylindrical, tube-like bases placed blow on the concave surface; flapper pressure to strike the top of the sample cylinder, and connected by bolts to the base platen; open resilient cage placed between said barrel-like strike hit the ring-like casing, open the closed resilient spacer the inner diameter of the circle coincides with the inner diameter of the ring-like hit. In the present invention, compaction of soil mechanics experiments in Preparation for the compaction of soil samples.
