PURPOSE:To enable to apply a consolidating force to earth of a slope and to obtain a spring water drainage path, by a method wherein, after a plural number of hollow anchor bolts is secured to a slope, head parts of every 2-3 anchors rods are tightened together to form a group. CONSTITUTION:A plural number of anchor bolts 11 is driven into a slope, at least a part of the anchor bolts 11, for example, 2 or 3 anchor bolts form a group, the anchor rods are stretched by coupling the head part of the anchor rod 11 by means of a tightening means 3 such as turn buckles, and the earth of the slope is previously consolidated by the tensible force and reaction force. In this case, the inside of the anchor bolt 11 is formed in a hollow so as to form a drainage path for underground water springing through the earth of the slope. |
