Ed TITAN Injection Anchors V:1 The difference in the application for soft soil stabilization 7 simple principles were realized in a standard application The flushing and supporting fluid is simple cement grout with a water to cement ration (WIC) of 0,4 to 0,7 (40 to 701ftres of water to 2 sacks =100 kg of cement). Under a flushing pressure of 5 to 20 Bars the walar Is quickly absorbed by noncohesive soils leaving a cementitions surface which cures and stabilizes the annulus. This method is also known when using supporting fluids for bored plies to DIN 4014. 2. Controlled bulb and Infiltration dowelling All TITAN drill bits have a radial flushing hole, which can be used to control the size of the bulb of the grout body. Excavated grout bodies having an average diameter of 1,5 to 2,5 times the drill bit dia- meter confirm that radial flushing at 5 to 20 Bars pressure -reams the sell and also causes the grout to penetrate into the grain structure of the soil. 3. Grouting pressures up to 60 bars In an open bore hole, a grout pressure of up to 60 Bars can be achieved, because camentituous grout with a W/C ratio of 0.4 is pumped while the pile/anchor is constantly rotated with slowly increa- sed grouting pressure. As with postgrouting the cured grout is cracked again by the rotation and the partly cured cement blocks move outwards and are wedged & ween the cured annulus and the rotating anchorlpile tube resulting In a natural packer. Since the TITAN method includes a similar effect to post grouting it eliminates this labor intensive porti- on of the job. 4. Improved anchoring capacity and reduced sett- ;ement Anchurs, piles and Soil nails are evaluated on their load and settlement characteristics taken from the load/settlements diagram. The calculated constant settlements are much less with the TITAN piles than with traditional bored piles or minipiles for identical soils under the same loads. The TITAN method grouted piles have much less settlements than traditionally Installed ones (see load/settlement diagram). Shear deformations (soil friction) between soil and the grout body are Important factors for uniform settlements. 5. The vibrating TITAN hollow anchor sets like a concrete vibrator during the drilling and grou- ting process and consequenty results in a homogeneous and compacted grout body. 6. Minimum grout cover, maximum corrosion pro- tection The down -the -hole circular centralizers, which are attached prior to each coupling along with the soft soil drill bit Incl, guide tube, maintain directional sta- bility during the drillingh process, and centralize the TITAN anchors in the bore holes, thus achiving a minimum grout cover of 20mm around the pile/anchor. A hollow soil nail creates a much higher shear resistance in the soil than a solid rod of the same cross sectional area The stiffer a nail is, the smaller the required shear movements need to be to activate the normal fares in the nail. TITAN Injection Anchors are 2 to 3 times stiffer than high tensile strands or bars under the same loads, since its cross section is larger. Prestressed TITAN anchors create much less movement in the sal than strands or bars under the same bad conditi. ons.
