ABSTRACT:
A ground anchor assembly comprises a looped cable 3 passing around a saddle 4 with one or more optional recesses 8 in its outer surface 7, all this being held in place by solidified grout or the like in an elongate bore 1. Extension 5 gives good transfer of forces when both cable ends are stressed outwards, and tubes 6 prevent internal cracking of the grout. After a period of use the cable 3 can be removed by pulling one cable end only.
More than one such cable 3 can pass round saddle 4, and more than one such assembly can locate in the bore 1.
