Concrete anchors with self-expanding pile anchors and pile anchors (ANCHOR)

摘要

The present invention relates to a self-expanding file anchor and a concrete anchor fitted with the file anchor. Conventional concrete anchors were simply anchored by the magnetic weight acting as a vertical phase, so they were attracted to large waves or currents during typhoons, making it difficult to properly anchor them.;SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide a self-deployment type blade piece (5) by drilling holes (3) and (103) on the surface or right and left side surfaces of a concrete body And the blade pieces 5 are deployed by small currents and waves that are normally developed and are deployed by the sand and tidal flats to allow an anchor excursion. The load of the concrete body 1 itself acts in the vertical direction, and the blade pieces 5 of the piles 4 latch and act in the lateral direction, so that the anchor ecology can be remarkably increased.
