Zusammenfassung:A soil core sampler is provided to allow a user to exactly observe a cut surface of a test sample by using a divided sample tube and to prevent the test sample from being dropped when the test sample is lifted on a ground surface. An outer tube(200) is introduced into or withdrawn from a ground layer. The outer tube is connected to a first connector of a power generator. An inner tube(300) is connected to a second connector of the power generator inside the outer tube, so that the inner tube is introduced into or withdrawn from the ground layer. A sample tube(400) is inserted into the inner tube. A core catcher(500) prevents a test sample of the sample tube from being dropped when the inner tube is withdrawn from the ground layer.
