Wiborex - Injection Drill Bolt System
Application Areas
Wiborex injection drill bolts are steel rods made of finegrained construction steel
equipped with coarse thread that can be used as consumable drilling bar, reinforcement
pipe, and injection pipe. Elongation with coupling sleeves, the ability to use
different drill bits and the ability to brace with nuts and a plate is possible due to
the continuous thread on the bar.
The Wiborex injection bolts make it possible to drill, inject, anchor and stabilize
all in one easy step with considerable time saving compared with normal bolting,
boring and injection methods. Wiborex injection bolts are used as rock bolts, as
pins, or as piles in mining, tunneling and specialized civil engineering. The permits
of the Wiborex 30/16, 30/11, 40/16, 73/53, and 103/78 systems have been obtained.
Application Areas
System anchors
Interception and stress relief bolting
Application as bonding shields
Tunnel repairs
Securing of slopes and excavation pits
Strata consolidation
Installation against avalanches
Securing of side-strips
Underpinning
Repairing of retaining walls

Used with Resins and Grouts
Wiborex injection drill anchors are offered in different dimensions for numerous
applications. Wiborex injection drill bolts are available in different corrosion
protection coatings (hot-dip galvanized, Duplex, INOX).
Used with resins and grouts
The two-component injection resins Carbolith Thix and Carbolith Flex are
especially suitable for bonding Wiborex injection drill bolts because the resins
cure within just a few minutes and the bolt can be loaded in a very short time.
Carbolith Thix is a rapid-hardening and rapid-curing silicate resin. It is CFC and
halogen free. Carbolith Thix may be used with overhead boreholes with large
diameters as well since it hardens very quickly right after mixing. Once both
components have been mixed together, the resin begins hardening, becomes
viscous and cannot flow even into large cracks on its own but has to be pumped
in. The mixture then cures into a viscoplastic silicate resin.
Wiborex injection
drill bolts facilitate
drilling, injecting,
bolting, and stabilizing
all in one easy
step.
Carbolith Flex is a medium setting, non-foaming two-component silicate resin. It is CFC free. Carbolith Flex
also reacts in the presence of running water. Its short setting time prevents material from being flushed
away by ground water movements. Once both components are mixed, the resulting viscous emulsion does
not absorb any additional water and does not mix with water either. The initially liquid resin mixture
quickly reaches a consistency where it no longer flows freely and then cures without further foaming.
All commercially available materials can be used in connection with the anchor grout and the cements.
For example, hydraulic ready-mix grout is suitable for rock anchors and injection work. The grout has to be
easily handled and pumped, has to be suitable for injection, and should not have a tendency to bleed or
segregate. To guarantee overhead work, the utilized grout should also be thixotropic.

Drilling Rigs
Ideally mounted pneumatic or hydraulic hammer drills are
used. Wiborex injection bored piles up to 40 / 16 rotate counterclockwise;
from 73 / 53 upwards they rotate clockwise.
Wiborex 52 / 26 is available as counterclockwise or clockwise
rotating bore pile.
Stressing/grouting of the Wiborex injection drill anchors can
be carried out
during the drilling procedure using cement suspensions.
This requires inserting a drill adapter into the flushing
head.
after drilling to the back of the borehole using
two-component resins, anchor grout or cement.
