PURPOSE: A tension device for an earth anchor is provided to increase the stability of an earth retaining wall structure, and to prevent a tension member from being slid onto a wedge member. CONSTITUTION: A tension device for an earth anchor comprises a tension device for an earth anchor, a lower hydraulic cylinder(100), and an upper hydraulic cylinder(200). The lower hydraulic cylinder is detachably connected to the upper part of a fixing head, and prevents a tension member from being separated from a wedge member insertion hole by pressurizing the upper surface of a wedge fixing head. The lower hydraulic cylinder fixes the tension member with a tensile force from the wedge member after the tension member is stretched. The upper hydraulic cylinder is connected to the upper surface of the lower hydraulic cylinder, and stretches the tension member. The upper hydraulic cylinder buffers the sliding of the tension member. |
