PURPOSE: A backflow prevention type waterproof packer for a ground anchor is provided to integrate an injection nozzle with a seamless packer fabric, thereby preventing the fabric from being burst when pressurizing a grout solution. CONSTITUTION: A backflow prevention type waterproof packer (100) for a ground anchor includes an injection nozzle (20), a packer fabric (30), and a backflow prevention unit. Outer surfaces at the front and the rear end of the injection nozzle are threaded, and a bonding plate is integrated with an outer circumferential surface at the middle of the injection nozzle. The packer fabric is formed into a cylinder with one seamless fabric, and is integrally bonded to the bonding plate. The backflow prevention unit is fastened to the threaded front end of the injection nozzle, and prevents the backflow of a grout solution. |
