The combined barb type anchor rod comprises an outer sleeve, wherein one end of the outer sleeve is used for being driven into the ground, theother end of the outer sleeve is inserted with an inner pull rod; a barb which can rotate relative to the inner pull rod is arranged on the side wall of the inner pull rod; a long hole which can enable the barb to extend out is formed in the side wall of the outer sleeve; and when the inner pull rod is pulled to enable the inner pull rod to axially move relative to the outer sleeve, the barb can extend out of the long hole. Therefore, the combined barb type anchor rod has the advantages that the barb which can rotate relative to the inner pull rod is arranged on the inner pull rod, the long hole which can enable the barb on the inner pull rod to extend out is arranged on the outer sleeve, and after the outer sleeve is driven into soil or placed into a pouring pool, the inner pull rod is pulled outwards relative to
