Displacement-suppressing anchor

Abstract

This product is a displacement-suppressing anchor that suppresses displacement caused by the load of a driven anchor. This product is mainly used on slopes, and when in use, as shown in the first reference diagram (before displacement) showing the state of use, the two cylindrical parts 2a and 2b that form the auxiliary anchor 2 are positioned on both sides of the direction (arrow) in which the central anchor 1 is displaced. When load displacement occurs in anchor 1, as shown in the second reference diagram (after displacement) showing the state of use, the two cylindrical parts 2a and 2b of the auxiliary anchor 2 come into contact with anchor 1 via the filler material 3, resisting the displacement of anchor 1 and moving away from each other while receiving the external force acting on anchor 1. That is, they move in a direction having a component in a direction substantially perpendicular to the direction of displacement of anchor 1, distributing the external force acting on anchor 1 to the surrounding ground and suppressing the amount of displacement of anchor 1. At this time, the range of movement of the cylindrical parts 2a and 2b is restricted by the stopper bolts that connect them. 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.
