A traveling soil compacting device and method for detecting a layer E modulus of a topmost layer of said bottom layer structure

摘要

The present invention relates to a movable device for compacting a soil layer structure (2), with at least one vibration means, such as a vibration roller (6) or a vibration plate (4), via which load pulses (P.) Compressing the soil layer structure (2) in at least one load introduction region (8) ) can be introduced, at least a first and a second detection means (10, 12) being provided for the detection of the modulus of elasticity of the base layer structure (2), which are arranged on the device (1) at a distance from one another such that the first detection means ( 10) detection in the load introduction area (8) and at least the second detection means (12) allow detection outside the load introduction area. The invention also relates to a method for determining a layer E module, the first detection means (10) being designed in such a way that it allows detection of a first value w1 of a depression depression (14) of the bottom layer structure (2) in the load introduction area, and the second detection means (12) is designed such that a second value w2 of the depression trough (14) can be detected outside the load introduction area (8).
