GULF
TUNNELING
Gulf Tunneling (GT) is an engineering firm that specializes in planning
and executing complex boring & tunneling works. We are considered the
biggest self-contained Micro-Tunneling company in the GCC. Our acquired
technological & operational experiencecoupled with the rapid growth
of the regionallows us to partake in great infrastructure projects and
developments throughout the State of Qatar, with over 45,000 meters of
tunnel currently installed or ongoing.
Our underground installations have reached remarkable depths, on every type of
ground condition, with pipe diameters reaching several meters. We have served
government agencies, gas majors, private contractors, and private developers
using our field-expertise and our fleet of equipment (including TBMs,
separation plants, control containers, cranes, water tankers, and more). Our
services include installation of all kinds of underground gravity and pressure
pipelines for drainage, water mains, and utility tunnels.
Since inception in 2002, GT has become a leader in the field of MicroTunneling. Our technical & commercial team is multinational, comprised of
professionals with project experience from around the world. HSE has always
been a top priority: we have maintained a record of zero Loss-Time Incidents
(LTI) in every project.

MICRO-TUNNELING
THE
IDEA
30
Gulf TunnelinG
Micro-Tunneling
As the name implies, micro-tunneling is the term for constructing small tunnels. These small diameter
tunnels make it impossible to have an operator inside the actual machine. Instead, the micro-tunnel boring machine (MTBM) must be operated remotely.
Operator
The operator directs the machine remotely from the safety of a control room on the grounds surface.
The operator is given constant feedback about the machine location, orientation, and corresponding hydraulic devices via a computer console. Machines also have video cameras and laser guidance that give
the operator more information. The operator controls the MTBM and the jacking frame with millimeter
precision.
Pipe
In most micro-tunneling operations the pipe is inserted from the entrance and pushed behind the machine. This process is often called Pipe Jacking. As the machine advances, more tunnel liner is pushed
from the entrance; thus, the speed of the advancing machine is controlled by the speed at which the
pipe is inserted.
Friction
As the length of tunnel increases, the friction against the earth around the pipe also increases.
Two practices are used to minimize this friction. First, over-cutting gives a slight gap between the inner edge of the tunnel and the outer edge of the liner. This requires a cutter wheel with a diameter
inch (12mm) to 4 inches (100mm) larger than the outside diameter of the liner. Second, an economical
and ecologically friendly lubricant, often bentonite slurry, is injected into this gap.
In addition to the actual lubrication effect, the pressure of the lubricant also prevents the gap from collapsing.
Longer
Tunnels
In addition to the jacking frame, smaller jacks, called interjacks, may be inserted between sections of
longer tunnel liners. These interjacks push the two sections of liner apart, while friction on the liner sections between the interjack and the tunnel entrance prevent the liner from sliding backwards. Therefore,
the liner behind the interjack does not move, and the sections in front of it receive additional pushing
force.

It is used for crossing waterways, roadways, shore approaches, congested areas, environmentally sensitive areas, and areas where other methods are costlier.
HDD is used instead of other techniques to provide less traffic disruption, lower cost, deeper and/or longer installation, no access pit, shorter completion times, added
directional capabilities, and overall environmental safety.

The technique has extensive use in urban areas for developing subsurface utilities as it avoids extensive open cut trenches. Uncontrolled drilling can lead to damages of
existing utilities, however; so, the HDD method necessitates that the operator has complete information about the existing utilities so that he plans the whole alignment in
a way that prevents any damage to them. Different government agencies have established legislation to ensure safe work execution and to authorize such work in urban
environments. Different trenchless-technology promoting organizations have developed guidelines for this technique in order to standardize of the techniques.
