Summary:The present invention relates to a supporter type compression expansion ground anchor comprising: a load transfer member (body) (110) longitudinally divided into a plurality of pieces while having a mounting groove (111) formed on the inner periphery thereof, a support piece (113) formed on the front end thereof toward the rear inner side thereof, and a band (117) coupled to the rear outer periphery thereof; a supporter (120) having a guide piece (121) formed on the rear end thereof to fit and restrain the support piece (113) while being elastically coupled to the support piece (113) of the inner member (body) (110) to protrude forward; a fixing head (130) for fixing the front end of multiple PC strands (150) while being coupled to the mounting groove (111) of the load transfer member (body) (110); the PC strands (150) tensioned by coupling the front end thereof to the fixing head (130) and coupled to the fixing head (130) at predetermined intervals by a heat shrinkable tube (150) or epoxy, wherein only the PC strands (150) between the heat shrinkable tube (153) and the fixing head (130) are maintained in a spiral state; and a corrugated tube (140) coupled to the fixing head (150) to embed the PC strands (150) therein. The supporter type compression expansion ground anchor of the present invention can improve tension, friction, and cohesion and suppress the generation of cracks due to the compression and expansion of the load transfer member (body) at the same time by firmly supporting the inside and the outside of the corrugated tube (140), firmly coupling the spiral part of the PC strands (150) to a grouting material to extend a bonded length, and filling grease (154) in a covered hose (152), thereby efficiently stabilizing a structure etc.
