<p>The method involves first irrupting borings into the ground with a hollow boring rod (9). Pointed bars or anchors (19) are set into these borings with some clearance. A hardenable mass is injected into the borings while simultaneously removing the boring rod. The bars or anchors remain in the boring. The hardenable mass is injected with a viscosity between 1,500 and 5,000 cP (centipoises).</p> |
