PRICKLE ANCHOR AND ITS FIXING

PURPOSE:To obtain a prickle anchor having great tensile resistance by a method in which plural bendable tension members having an uneven surface are driven into the ground in a form of tree roots, and the upper ends of the members are bundled by a fitting tool. CONSTITUTION:A bottomed cylindrical guider 15B is set on the ground G, and one ends of bendable tension members 12 having uneven surfaces penetrate through each cylinder 15b of the guider 15B. The other ends of the members 12 are housed in a guide tube 15A and then a piston 17 is pushed down. Whereupon, the members 12 are guided to the guide cylinder 15b and gradually penetrated into the ground G while being bent outwards. Afterwards, the guider 15B is removed out, and the upper ends 12b of the members 12 are bundled by a fitting tool 11. A prickle anchor having great tensile resistance can thus be constructed without use of grouting material.
