2112741 9301360 PCTABS00019 A soil anchor body (11) of folded sheet steel is hammered down into the soil by means of a rock drill rig. It carries with it a hose (19) coupled to its rear end and one or more steel ropes (29) deviated over its front end. The drill rod is withdrawn and cement grout is injected through the hose into the anchor body to inflate it. The steel ropes are now anchored and both ends of each rope are above ground and ready to be used to take tension load. If the soil anchor is only temporary used, the steel ropes can be withdrawn simply by being pulled at one end.
