Drivable device for compacting a soil layer structure and method for ascertaining a layer modulus of elasticity of an uppermost layer of this soil layer structure
First Claim
1. A drivable device for compacting a soil layer structure, comprising:
- at least one vibration device configured to introduce load pulses (P) into at least one load introduction area for compacting the soil layer structure; and
at least one first and one second detection devices for detecting the modulus of elasticity of the soil layer structure, wherein the first and second detection devices are situated spaced apart from one another on the drivable device in such a way that the first detection device allows a detection in the load introduction area and the second detection device allows a detection outside the load introduction area.

Abstract
The present invention relates to a drivable device for compacting a soil layer structure, having at least one vibration means or device, such as a vibration roller or a vibration plate, via which load pulses (P), which compact the soil layer structure, can be introduced into at least one load introduction area. At least one first and one second detection means or devices for detecting the modulus of elasticity of the soil layer structure are provided, which are situated spaced apart from one another on the drivable device in such a way that the first detection means or device allows a detection in the load introduction area and at least the second detection means or devices allows a detection outside the load introduction area. The present invention also relates to a method for ascertaining a layer modulus of elasticity.

12. A method for ascertaining a layer modulus of elasticity of a layer of a soil layer structure during a soil compaction procedure, comprising:
-
introducing at least one load pulse (P) into a load introduction area via a surface of an uppermost layer of the soil layer structure; detecting a first value (w1) of a depression trough of the soil layer structure in the load introduction area via a first detection device, ascertaining an equivalent modulus of the soil layer structure from the detected first value (w1) of the depression trough; detecting a second value (w2) of the depression trough outside the load introduction area via a second detection device, ascertaining a bedding modulus of the soil layer structure from the detected second value (w2) of the depression trough; ascertaining the layer modulus of elasticity of the uppermost layer of the soil layer structure from the two detected values (w1, w2) of the depression trough and the ascertained equivalent modulus or the bedding modulus, wherein the load pulse (P) is introduced via a vibration device of a soil compaction machine into the soil layer structure. - View Dependent Claims (13, 14, 15)
