ABSTRACT:
A method and device for anchoring a strut such as a stockade, ground mark or guardrail to the ground, in which a top plate is formed with a bore for accomodating the strut, and radial plates are secured to the bottom of the top plate. The radial plates radially extend outward from the center of the bore of the top plate and have a cut-out portion to support the strut. The bore of the top plate is sized to be larger in diameter than the strut so that the strut can be orientated within a given range. A plurality of clamping means are provided on the top plate and adapted to radially urge the strut thereby to determine the orientation of the strut relative to the center of the bore of the top plate. A strut anchoring device thus constructed is placed on the ground which is slightly digged and driven into the ground by driving a driving pope or tool abutting against a bearing surface provided in the radial plates until the top plate reaches the ground surface. Thereafter, the driving pope is pulled out of the device and the strut is inserted into a cavity defined by the driving pope until the lower end of the strut abuts against the bearing surface of the radial plates. Subsequently, the orientation of the strut with respect to the center of the bore of the top plate is adjusted by adjusting the clamping means provided on the top plate. To increase the resisting strength of the radial plates, a desired number of reinforcing or stabilizing plates are provided which are adapted to be driven into the ground through bores formed in the top plate at suitable locations.
