TITAN Injection Anchors Al A new dimension for soft soil stabilization TITAN Drill -and Injection Anchors could cdso be used as piles or nails and are suitable for use as anchors, micro piles, soil nails, rock bolls or the reinforced soil method. DIN 4125 ",routed anchors" Nov. 1990 applies for all stressed anchors which have a free (unbonded) length, and which lal.e tensile forces only. DIN 4128 "grouted piles" April 1983 applies for micro piles and soil nails which take loads on tension and com- prossionand which are grouted over their entire length. Soto nails act like a frictional reinforcnhent (hooke) in rein- forced concrete or like dowels or nails in timber construction taking shear loads. This new anchoring technique began In 1983 and is covered by patent nos. P 3400182 and P 38 28 335. A unique feature Is the drill steel use as the tension- and I or compression member. The principle of the TITAN Drill- and Injection Anchor is based on the combination of 7 ideas: 1. Utilization of a drill steel as an anchor Promthe statir, point of view, a tube is superiur to a solid rod of the same cross sectional wren with respect to ban- 5 ding moment, shear resistance and surface bondlfnction. 2. Creation of an economically priced one-time use drill rod and drill bit Ibis technique eliminates two labor intensive elements namely irquirrd for anchor installations. They are: file insertion of the anchor itself and the remo- val of die drill rod and the casing. Consequently smaller drill rigs can be used, the amount of grout is teduc:ed and substantial labor striving-. ate achieved. 3. Utilization of the drill steel as grouting conduit for fil- ling the annulus from the bottom -up This guarantees a positive complete tilling of the annulus as well as all fissures and cracks. This method Is much ansicr than using additional tubes for grouting, air vents and post -grouting. 4. The choice of a high quality structural steel otters high notch toughness > 39 J in comparison to high tensi- le rods or strands having > 15 J or glass fibre anchors. This steel is riot affected by hydrogen embattlement or by post rolling heat treatment. In addition. it offers high shear resistance. The use of a ferritic-austenitic stainless steel TITAN-INOX for permanent anchors with a life span of 50 years and more This material (no. 14462) ib equivalent to -double corrosl- on- DIN 50929 part 3 - likeliness of corrosion in con- struction pans and underwater construction. working with this TITAN-INOX Material Is much easier than with tlx: standard permanent anchors which are surrounced by grout it, ccrrugnted plastic tube, especially as far as extension (Coupling) and the. preparation for the anchor head are concerned. 6. The threads on the TITAN anchors are formed much like the ribs on a reinforcing bar fabricated according to DIN 486 thin deep I IIAN lhicad:; resx'". at 2.4-limes higher bond friction compared to standard drill ;;te:d coil-tiveads of R 32 (1-;:') or R 38 (1- V') 7. Continuous threads guarantee the TITAN anchor can be cut or coupled anywhere along its length. Cutting, extending, pro stressing and load releasing on the anchor are possible. A thread pitch of 6' eliminatrs the. need far cuunter ruls al each coupling. TITAN 30/16 r TITAN 103i78
