ABSTRACT:
Anchoring rods which have one end thereof secured in a bore hole of the earth or rock by surrounding cement are sometimes made more secure in the earth by one or more devices which surround different parts of the buried portion of the rod and have means for supplying additional cement at high pressure thereto to crack a portion of the surrounding cement and press additional cement into the earth adjacent the area of the device thereby forming a bulge in the anchoring cement. This disclosure relates to a device of this type which, however, has an elongated body of elastic material with a longitudinal slit or opening adapted to surround the anchoring rod and be retained thereon at the desired site and which body contains an opening or channel spaced from the rod-surrounding opening or slot substantially parallel to the latter which defines a distribution channel and has an orifice therein which is ordinarily covered by the body of the device. Under pressure, however concrete will pass out of the orifice and to the outside of the device to crack the surrounding concrete.
