ー。[Scope of Claim for Utility Model Registration] (1) A backflow prevention packer for an earth anchor that is installed to prevent sand and gravel from flowing into a casing pipe when turning the earth anchor, which has a circular hole in the center; A plate-like body made of an elastic material having radial notches extending radially from the circular hole is axially blocked by the notch of one of a pair of adjacent plate-like bodies by the other plate-like body. A backflow prevention packer for an earth anchor, characterized in that a plurality of backflow prevention packers for an earth anchor are attached to the inner periphery of the tip of the casing pipe at predetermined intervals in the axial direction. (2) In the backflow prevention packer for earth anchors as set forth in claim 1 of the above utility model registration claim,
A backflow prevention packer for an earth anchor, wherein the diameter of the circular hole in the plate-shaped body is smaller than the diameter of the tensile steel material inserted into the casing pipe.
