PERMANENT GROUND ANCHOR USING MULTI-STAGE BEARING PLATE

PURPOSE:To obtain permanent useful life by a method in which the tensile forces from a load bearing material to the surrounding ground is dispersed to places in the direction of depth by using a multi-stage bearing plate for ground anchors. CONSTITUTION:The first bearing plate 21 is attached to the tip of the first tensile steel material 11, the first load bearing material 31 is contacted with the extraction side of the plate 21, and the second distribution plate 22 is set on the extraction side end of the material 31. The second load bearing material 32 is contacted with the extraction side of the plate 22, and thereafter a desired stage number of bearing plates, tensile steel materials, and load bearing materials are connected in series. The load bearing materials 3 are bonded by a sleeve nut-like joint 15, holes through which the tensile steel materials 1 are passed are formed in the bearing plates 2, and an anticorrosive grout is packed into the hollows of the materials 3.
