The present invention relates to a packer expansion type ground anchor body. The packer expansion type ground anchor body comprises: an inner body (120) enclosing the outer circumference of a packer (150) and having a hanging protrusion (123) at a rear end, wherein the inner body (120) includes one or more bending members (125) and the outer circumference is in contact with an excavation hole (1); a support unit (130) including a fixing unit (131) having a hanging groove (132) corresponding to the hanging protrusion (123) of the inner body (120) and improving adhesion; and a tension member (140) connected to the inner side of the fixing head (110) by a compression grip (131). The inner body (120) connects an expansion piece (121), a control piece (124), and a finishing piece (126) by the bending member (125) to be bent against each other. Multiple hanging protrusions are formed on the surface of the inner body (120) so the inner body (120) is in contact with the inner circumference of the excavation hole (1) in a horizontal state in order to increase a frictional force and a pressing force so that the anchor body can be strongly anchored. Therefore, the packer expansion type ground anchor body can prevent a large scale accident due to a ground failure by reinforcing strength in the excavation hole. Also, the packer expansion type ground anchor body can be used for multiple purposes as the length of the inner body can be easily adjusted and applied as necessary. |
