Abstract: An apparatus for laying sheet material securely over a ground surface. The apparatus includes a first device configured to roll along the material. The first device creates a groove in the ground and simultaneously presses the material into the groove. A second device follows the first device and presses the ground together on opposite sides of the groove to secure the material into the groove.

Abstract: An anchoring apparatus for securing a pole into ground, which includes a tubular section being retained in the ground for supporting the pole. A support element is disposed on the open end of the tubular member, for supporting the pole proximate to the open end. The support element includes an annular outer member, which is rotatably disposed on the tubular section, and includes a support aperture eccentrically offset with respect to the center of the outer member. An annular inner member is rotatably disposed within the support aperture, and includes a receiving aperture eccentrically offset with respect to the center of the inner member, for supporting the pole. The outer member and inner member are respectively rotatable to vary the positions of the support aperture and the receiving aperture, so as to selectively tilt the poles longitudinal axis to a desired position with respect to the direction of the longitudinal axis of the tubular section.

Abstract: A device for the vertical arrangement of a pole or post-like object is disclosed. A securing device is disposed at the ground end and includes a substantially cylindrical, elongated mounting mandrel which projects upwards from the free upper side of the securing device. This mandrel can be inserted into an accommodating bore in the underside of the pole or post-like object. A support plate on which the underside of the pole or post-like object rests, has at least one securing projection that protrudes upwards from the support plate and penetrates the material of the pole or post-like object. The mounting mandrel is substantially thinner than the accommodating bore in the underside of the pole or post-like object such that a play is provided between the outer periphery of the mounting mandrel and the inner circumferential area of the accommodating bore seen substantially over the entire axial extension of the mounting mandrel.
