<strong>Wiborex</strong> <strong>Injection</strong> <strong>Drill</strong> <strong>Bolt</strong><br />
Self-<strong>Drill</strong>ing Anchor System<br />
for Mining and Tunneling<br />
Solutions from Materials Technology
<strong>Wiborex</strong> - <strong>Injection</strong> <strong>Drill</strong> <strong>Bolt</strong> System<br />
Application Areas<br />
<strong>Wiborex</strong> injection drill bolts are steel rods made of finegrained construction steel<br />
equipped with coarse thread that can be used as consumable drilling bar, reinforcement<br />
pipe, and injection pipe. Elongation with coupling sleeves, the ability to use<br />
different drill bits and the ability to brace with nuts and a plate is possible due to<br />
the continuous thread on the bar.<br />
The <strong>Wiborex</strong> injection bolts make it possible to drill, inject, anchor and stabilize<br />
all in one easy step with considerable time saving compared with normal bolting,<br />
boring and injection methods. <strong>Wiborex</strong> injection bolts are used as rock bolts, as<br />
pins, or as piles in mining, tunneling and specialized civil engineering. The permits<br />
of the <strong>Wiborex</strong> 30/16, 30/11, 40/16, 73/53, and 103/78 systems have been obtained.<br />
Application Areas<br />
System anchors<br />
Interception and stress relief bolting<br />
Application as bonding shields<br />
Tunnel repairs<br />
Securing of slopes and excavation pits<br />
Strata consolidation<br />
Installation against avalanches<br />
Securing of side-strips<br />
Underpinning<br />
Repairing of retaining walls
Used with Resins and Grouts<br />
<strong>Wiborex</strong> injection drill anchors are offered in different dimensions for numerous<br />
applications. <strong>Wiborex</strong> injection drill bolts are available in different corrosion<br />
protection coatings (hot-dip galvanized, Duplex, INOX).<br />
Used with resins and grouts<br />
The two-component injection resins Carbolith Thix and Carbolith Flex are<br />
especially suitable for bonding <strong>Wiborex</strong> injection drill bolts because the resins<br />
cure within just a few minutes and the bolt can be loaded in a very short time.<br />
Carbolith Thix is a rapid-hardening and rapid-curing silicate resin. It is CFC and<br />
halogen free. Carbolith Thix may be used with overhead boreholes with large<br />
diameters as well since it hardens very quickly right after mixing. Once both<br />
components have been mixed together, the resin begins hardening, becomes<br />
viscous and cannot flow even into large cracks on its own but has to be pumped<br />
in. The mixture then cures into a viscoplastic silicate resin.<br />
<strong>Wiborex</strong> injection<br />
drill bolts facilitate<br />
drilling, injecting,<br />
bolting, and stabilizing<br />
all in one easy<br />
step.<br />
Carbolith Flex is a medium setting, non-foaming two-component silicate resin. It is CFC free. Carbolith Flex<br />
also reacts in the presence of running water. Its short setting time prevents material from being flushed<br />
away by ground water movements. Once both components are mixed, the resulting viscous emulsion does<br />
not absorb any additional water and does not mix with water either. The initially liquid resin mixture<br />
quickly reaches a consistency where it no longer flows freely and then cures without further foaming.<br />
All commercially available materials can be used in connection with the anchor grout and the cements.<br />
For example, hydraulic ready-mix grout is suitable for rock anchors and injection work. The grout has to be<br />
easily handled and pumped, has to be suitable for injection, and should not have a tendency to bleed or<br />
segregate. To guarantee overhead work, the utilized grout should also be thixotropic.
<strong>Drill</strong>ing Rigs<br />
Ideally mounted pneumatic or hydraulic hammer drills are<br />
used. <strong>Wiborex</strong> injection bored piles up to 40 / 16 rotate counterclockwise;<br />
from 73 / 53 upwards they rotate clockwise.<br />
<strong>Wiborex</strong> 52 / 26 is available as counterclockwise or clockwise<br />
rotating bore pile.<br />
Stressing/grouting of the <strong>Wiborex</strong> injection drill anchors can<br />
be carried out<br />
during the drilling procedure using cement suspensions.<br />
This requires inserting a drill adapter into the flushing<br />
head.<br />
after drilling to the back of the borehole using<br />
two-component resins, anchor grout or cement.
