A ground pressure type anchor and the construction method are provided to fix an anchor in the earth by using bearing pressure of a wedge wing driven into the ground in the wedge type without using frictional force of grout, and to keep an anchor not to be drawn out and to shorten a period of curing by fixing a wedge wing in the earth before the initial tension of a tension member for fixing a wedge wing. A ground pressure type anchor includes a taper type fixing head(10) having the external diameter narrowing toward the rear, many wedge wings(20) arranged on the circumference of the fixing head in the circumferential direction and supported to slide and widening with the tension of the fixing head to get driven in the earth and to press, a fixing piece(30) connected to the circumference of the fixing head to move forward and backward and advancing the wedge wing to get driven in the earth and fixed, and many tension members(40) tensing the fixing head and operating the wedge wing. |
