A re-tentionable anchor system is provided to prevent a tension member from protruding upwards by connecting an anchor tensioning device with the tension member via an anchor head. A re-tentionable anchor system comprises a tension member(100), an anchor head(300), a ground pressing plate(200), and an anchor tensioning device. The tension member is inserted in a hole(H) under the ground. The anchor head fastens the upper end of the tension member to cause the tension member to keep constant TS(Tensile Strength). The ground pressing plate is installed between the anchor head and the surface of the ground. The anchor tensioning device, which is connected with the anchor head, includes a support unit, a plurality of anchor bolts(240), a lift unit, and a cylinder unit. The support unit, which is located on the ground pressing plate, has a holed support plate, support legs(440), and support members(460). The support legs separate the ground pressing plate from the support plate. The support members are installed at the bottom of the support legs. The anchor bolts are mounted on the ground pressing plate. The lift unit, passing through the support unit, is fastened to the anchor head. The cylinder unit is installed between the support unit and the lift unit to move the lift unit up and down. |
