The present invention relates to a pressurized micro-pile with intensified bearing power and a method of constructing the pressurized micro-pile. The method of constructing a pressurized micro-pile comprises the followings of; inserting a corrugated pipe and a reinforcing material in a bored hole and a casing, which is installed inside the bored hole, in regular sequence and injecting a first grout material into the bored hole and the casing by using a gravity feeding method; closing the corrugated pipe and a connection member fixed on the corrugated pipe by using a cap, which is combined with a reinforcing material, when the casing is drawn; sealing a space between the corrugated pipe and the bored hole by expanding the corrugated pipe and a packer installed on the upper end part; and instilling the first grout material into the ground by additionally injecting a second grout material through a grout injection hole, which is disposed on a cap, into the bored hole and the casing by using a press-feeding method. Therefore, the pressurized micro-pile has intensified bearing power for maximizing a friction force between the ground and the micro-pile. |
