1. A soil compacting device, comprising:
- a frame supporting a heel having a convex surface, from a front to a rear of the device in an advance direction of the device, with a convexity toward soil depth in a working position of the device, the frame including a vertical post,wherein a front wedge-shaped tool is on a front part of the heel, an edge of the wedge-shaped tool forming a leading edge provided at the front of the frame and parallel to a surface of soil, the leading edge having the same width as the heel, the front wedge-shaped tool being disposed closer to the vertical post of the frame than the convex surface of the heel such that a part or the entire convex surface of the heel is configured to be disposed below the surface generated by the leading edge when the tool is advanced parallel to the soil, the heel compacting the soil as the device is advanced,the soil compacting device is configured to compact the soil through forward advancement of the device parallel to the soil, andthe heel is formed with a smooth surface.

20. A soil compacting device, comprising:
-
a frame supporting a heel having a convex surface, from a front to a rear of the device in an advance direction of the device, with a convexity toward soil depth in a working position of the device, the frame including a vertical post, a front wedge-shaped tool being on a front part of the heel, an edge of the wedge-shaped tool forming a leading edge provided at the front of the frame and parallel to a surface of soil, the leading edge having the same width as the heel, the front wedge-shaped tool being disposed closer to the vertical post of the frame than the convex surface of the heel such that a part or the entire convex surface of the heel is configured to be disposed below the surface generated by the leading edge when the tool is advanced parallel to the soil, the heel compacting the soil as the device is advanced; an intermediate part provided with a known support, which includes a longitudinal hole configured to receive soil decompacting tools, a flat part being disposed on a lower portion of said support, said flat part being attached on a lower end of said support, the front end of the lower portion of the flat part being provided with a first vertical fin with a hole at the front, a rear end of the lower portion of the flat part being provided with three holes spaced in a height direction, the support/flat part assembly forming said intermediate part; and a compacting part provided with a blade having a curved shape whose concavity is directed upward, said blade reproducing a curve of settlement under a repeated effect of the passages of a compactor acting from the surface, said blade comprising a second vertical fin attached on the upper portion of the blade, the front of the second vertical fin being provided with a hole and, at the rear of the second vertical fin being provided with three holes spaced in the direction of the height, the two fins being positioned against one another by aligning the two front holes and by pushing into the two front holes fastening means which allow rotation of the second vertical fin on the surface of the first vertical fin, the rear holes on each of these fins being spaced so that when the second vertical fin is rotated on the first vertical fin, only one of the rear holes of the second vertical fin corresponds to only one rear hole of the first vertical fin, to obtain three positions of the fins relative to each other and thus three different eccentricities for said blade, wherein the soil compacting device is configured to compact the soil through forward advancement of the device parallel to the soil.
