Abstract
PURPOSE: To form an anchor without any device for tightening anchor steel wires by injecting a fluid into a diameter expanding tube made of an elastic material which is with a plurality of anchor steel wires while an expansion preventing ring is provided at a proper point.
CONSTITUTION: A tube 1 for a diameter expanding tube made of an elastic material is covered with a plurality of anchor wires 2 while an expansion preventing ring 3 is fitted into the outside of the anchor steel wires 2 along the length of the wires at a proper interval. In addition, a retaining member 22 is mounted at the base end of the steel wires to form an expansion anchor 4. The expansion anchor 4 is inserted into an anchor hole 6 in the subsoil 5. After a primary injection tube 7 inside the tube 1, an internal pressure protective cylinder 10 and an external pressure protective cylinder 15 outside the anchor steel wires are separately closed with bands 12, 13 and 16, a fluid is injected into the tube 1, which is fixed firmly into the subsoil by tightening. Numeral 32 indicates an external cauking.
