ANCHORING DEVICE IN BOREHOLE

摘要

A threaded anchor rod 3 is secured in a borehole 2 by driving it at an elevated temperature, into a rod-like plastics body 1 consisting of a thermoplastic or thermosetting granular plastics material, the shape of the body 1 being achieved by sintering or by enclosing the granules in a frangible container. The heat from the rod softens the body 1 and causes it to adapt itself to the interior of the borehole 2 and the exterior of the rod 3.
