Auxiliary anchor

Abstract

This product is an auxiliary anchor that suppresses the displacement of driven anchors due to load. This product is mainly used on slopes, and as shown in the first and second reference diagrams showing the state of use, the two cylindrical parts of the auxiliary anchor are positioned on either side of the direction (arrow) in which the central anchor is displaced when in use. When load displacement occurs in the anchor, as shown in the third and fourth reference diagrams showing the state of use, the auxiliary anchor contacts the anchor to resist its displacement and absorbs the external force acting on the anchor, while moving in a direction that has a component approximately perpendicular to the direction of the anchor's displacement, so that the two cylindrical parts move away from each other, thereby distributing the external force acting on the anchor to the surrounding ground. At this time, the range of movement of the cylindrical parts is restricted by a stopper. With this product, anchors used for holding fences, etc., can be installed even in soft ground (e.g., N-value of 4 or less) with boulders or bedrock present.
