发明名称 POINT ANCHORING
摘要 An anchor bolt (20) is quickly point anchored in a borehole (10) by means of a capsule (1) having two compartments (A and B). Compartment (B) which, in use is nearest the blind end of the borehole (10), contains a first anchoring means to form an adjustable load bearing annulus (C), and compartment (A) defines a second anchoring means to provide a permanent load bearing annulus (D), e.g. of set resin. In use, the capsule (1) is pushed up the hole (10) followed by the bolt (20) which is driven through the capsule and rotated.
