PURPOSE: A hydraulic wedge press device is provided to prevent the sliding between a wedge and an anchor member and the inequable compression of the wedge, thereby improving an efficiency and safety of a compression work. CONSTITUTION: In the hydraulic wedge press device(20) for preventing the generation of sliding loss between a wedge(11) and an anchor member(10) caused during a steel wire(12) is tensioned and anchored with a tortuous hydraulic cylinder(30) as well as the inequable compression of the wedge, the steel wire freely pass through the inner wall of an inner cylinder(22) and an outer diameter of a piston(23) is set in consideration of the insertion of the steel wire. A hydraulic pressure of a hydraulic chamber(28) between the inner cylinder, an outer cylinder(21), and the piston is used to push the piston to compress the wedge into the anchor member, and the piston is assembled with a screw(25) so as to be returned to its original position by a spring after the hydraulic pressure is canceled.
