PURPOSE: A double sealing pressure type soil nailing method is provided to securely reinforce the ground and to easily install a packer in a reinforcing member. CONSTITUTION: A double sealing pressure type soil nailing method is as follows. A reinforcing member with a packer(110) is inserted into a perforated hole. The packer is filled with grout materials using a packer filling hose(150) and is expanded. The grout materials are injected into a space between the top end of the expanded packer and the ground. The grout material is injected into the perforated hole through a grouting injection hose(130) using a pressure pump. Air and water in the perforated hole are discharged to outside through an air exhaust hose(140).
