THE IDEA
30 GULF TUNNELING
7/17/2019 Gulf Tunneling Company Profile
http://slidepdf.com/reader/full/gulf-tunneling-company-profile 33/54
▌ MICRO-TUNNELING As the name implies, micro-tunneling is the term for constructing small tunnels. These small diamtunnels make it impossible to have an operator inside the actual machine. Instead, the micro-tunning machine (“MTBM”) must be operated remotely.
▌ OPERATOR The operator directs the machine remotely from the safety of a control room on the ground’s surfaThe operator is given constant feedback about the machine location, orientation, and correspondindraulic devices via a computer console. Machines also have video cameras and laser guidance thatthe operator more information. The operator controls the MTBM and the jacking frame with millimprecision.
▌ PIPEIn most micro-tunneling operations the pipe is inserted from the entrance and pushed behind the chine. This process is often called “Pipe Jacking”. As the machine advances, more tunnel liner is pufrom the entrance; thus, the speed of the advancing machine is controlled by the speed at which tpipe 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 thner edge of the tunnel and the outer edge of the liner. This requires a cutter wheel with a diameterinch (12mm) to 4 inches (100mm) larger than the outside diameter of the liner. Second, an econoand 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 fromlapsing.
▌ LONGER TUNNELSIn addition to the jacking frame, smaller jacks, called “interjacks,” may be inserted between sectiolonger tunnel liners. These interjacks push the two sections of liner apart, while friction on the line
tions between the interjack and the tunnel entrance prevent the liner from sliding backwards. Therthe liner behind the interjack does not move, and the sections in front of it receive additional pushforce.

GTuses the world’s most reliable Micro-Tunneling machine, Herrenknecht
AVN type—complete with all equipment—to drive non man-entrytunnels, using pipe-jacking techniques in the trenchless concept of
pipe works. This modern machine type now allows access to the working facefrom the jacking pit via a door just behind the cutting face. Obstacles such as sheetpiles, steel girders, and boulders can now simply be removed. This new accessalso provides the ability to replace worn cutter rings, allowing tunneling in hardrock to be extended to retention lengths of over 500m.
This system is ideal for use in urban areas. Additional ground-improvementprocesses will be unnecessary (such as compressed air, ground treatment, orfreezing), and the convenient size of the launching and reception shafts allow for:
▌ Minimal disturbance to traffic ▌ Maximum possible conservation of protected landscape areas
▌ Compact containerized equipment design on the surface
CREW
The Gulf Tunneling crew that is responsible for the Herrenknecht AVN machinesoperation and maintenance are:
▌ MT engineer/operator ▌ MT fitter & welder ▌ MT electrician ▌ 5-7 laborers
M/S Herrenknecht will provide direct technical assistance and/or presence on a
need-to basis in the rare case of unforeseen difficulties during execution.
SYSTEM COMPONENTS
Micro-tunneling system components used on most projects include:
▌ Micro-tunneling machine c/w cutting head ▌ Control container c/w power pack module ▌ Jacking frame ▌ Interjack stations ▌ Separation plant c/w tanks with fresh water storage capacity ▌ Mobile crane to set up the machine and to handle the pipes ▌ Bentonite pump and bentonite system ▌ Feed and slurry pumps ▌ Pipe rack to hold feed and slurry pipes ▌ Shaft feed and flexibile slurry lines ▌ Launch seals ▌ Laser guidance system ▌ Generator with sufficient power output for all components’ requirements ▌ Launch and reception shafts
▌ Jacking pipes 3 meters long ▌ Water supply
KEY ADVANTAGES TO MICRO-TUNNELING/PIPE-JACKING
Micro-Tunneling and Pipe-Jacking is reliable and cost-effective. Key advantainclude:
▌ Minimal earth moving (only for launching & receiving shafts) ▌ Absence of ground-water lowering (thus preventing dangerous settlemen
building foundations and road services) ▌ Optimal protection for people and nature ▌ Minimal effect to traffic and pedestrian mobility above ground ▌ Flexible driving alignment (i.e. curved or linear)
▌ All-weather construction (thus allowing for rapid completion and meetingdeadlines)

7/17/2019 Gulf Tunneling Company Profile
http://slidepdf.com/reader/full/gulf-tunneling-company-profile 37/54
2.1 Micro-Tunneling Machine c/w Cutting Head
The cutting head of the tunneling machine is fitted with disc cutters to cut theentire face of the tunnel, and is designed in a manner to operate in saturatedground with water pressure.
The excavated material passes through openings in the cutting head to the crushing& mixing chamber. The conical crushing chamber reduces the excavated materialto a size suitable for conveying to the surface separation plant. Transportation ofcrushed material is achieved by using injected water through the feed nozzles,which carry it through the back pipe. Crushing the excavated material minimizesblocking of system components.
The cutting wheel is driven by means of hydraulic motors located within the cuttinghead assembly. This renders both excavating and crushing powers independentfrom the distance to the launch shaft.
The rotation of the cutting head and transportation of the excavated material iscontinually controlled and operated while the TBM progresses forward.
The advance movement of the cutting head is achieved by the jacking forces fromthe pipes behind as they are pushed forward with hydraulic rams located in the
jacking frame.
The following are special features for AVN machines:
▌ Designed for soft ground, mixed ground, and especially hard rock conditions byuse of different cutting wheels (full face excavation)
▌ Central access to cutting wheel for tool replacement (back-loading system) ▌ Highly reliable steering operation due to inductive measuring system ▌ Variable flushing modes / jet systems to suit different ground conditions ▌ Superior cone crusher ▌ Heavy-duty, long-life main bearing and high torque peripheral drive ▌ Hydraulic power pack in machine can ▌ Completely remote-controlled
(All machines compatible with U.N.S. Guidance System.)

2.2 CONTROL CONTAINER
Both the control station and the power pack modulesare housed within the same standard controlcontainer, thus facilitating the setup and relocationaround the site. For the machine, the container willbe located adjacent to the launch shaft.
The control container is a management device,where all system components can be operated andmonitored via the on-board computer system andan array of measurement devices. Three steeringcylinders enable millimeter boring precision from theoperator’s panel in the control container. Steeringmovement in any direction allows operator to correctalignment or curve the drives with the simple pushof a button.
The control room is set as close as possible to theexcavated shaft, so convenient monitoring by theoperator is continuously available.

2.3 JACKING FRAME
The jacking frame consists of hydraulic rams, which constantly push the jackingpipes into the bored tunnel. The jacking frame rests on the floor of the launchshaft. The shaft wall provides the reaction to the pipe thrusting forces by meansof a concrete thrust pad, that is cast into place after the frame is positioned.

2.4 LASER & GUIDANCE SYSTEM
7/17/2019 Gulf Tunneling Company Profile
http://slidepdf.com/reader/full/gulf-tunneling-company-profile 40/54
A laser guidance system was developed specifically for use with this Herrenknecht AVN machine. An electronic laser is preset to the desired grade and alignment(i.e. vertical & horizontal axis) where the target plate is hermetically sealed withinthe cutting head. This enables the laser beam to define the exact position of thecutting head at all times during the drive.
The system consists of a target unit and a laser set. Via the main processor, theactual position for the cutting head is calculated and displayed graphically on a
monitor conveniently located in the operator’s control panel. A measuring wheelalso provides continuous measurement of the tunnel length.
The computer-controlled guidance system constantly monitors all operatingfunctions of the system, with continuous data updates that enable print-outswhenever necessary. A complete time-log of each drive is a lso recorded for futurereference.
Furthermore, the guidance system provides a constant record of the following data:
▌ Date & time ▌ Total drive length (m) ▌ Line & level (mm) ▌ Vertical & horizontal angle of the cutting head assembly (mm/m)
▌ Stroke of all steering cylinders (mm) ▌ Thrust of the jacking rig (tons) ▌ Torque at the cutting wheel (bars)

2.5 MATERIAL CONVEYANCE AND SEPARATION
A feed pump located next to the fresh water tank on the surface pressurizes thefeed water to the crushing chamber/cone nozzles. The reduced excavated material
mixes with feed water to form slurry. This is pumped out by slurry pumps (locatedinside the tunnel and at the bottom of the launch shaft) towards the separationplant where materials are separated from water and clean water is returned totanks.
GULF TUNNELING
7/17/2019 Gulf Tunneling Company Profile
http://slidepdf.com/reader/full/gulf-tunneling-company-profile 42/54
The bentonite mixture acts as a lubricant and face support medium in the pipe jacking process. Through injection nozzles in the pipe, the mixture is forced into anannulus that results from a deliberate diameter difference between the tunneling machine and the concrete pipe. The resulting upward pressure reduces pipe frictionand, subsequently, the necessary jacking forces.
In any desired product pipe, a bentonite station with three ball valves may be installed. This station connects each valve to the evenly-distributed nozzles on the
circumference of the product pipe. An electrical signal from the container activates the individual pneumatically-controlled valves. A pneumatic actuator opens the ballvalve and enables bentonite to flow through the selected nozzle.
2.6 BENTONITE PUMP& BENTONITE SYSTEM
The bentonite pump and system’smain purpose is to reduce friction.The activity of the slurry pumps (usedto remove the spoil) is constantlymonitored to maintain maximumrecovery of excavated material. Thisis necessary because the spoil tendsto flow towards the pipe/soil annulus,and that increases the external frictionbetween these surfaces.

2.7 LAUNCHING SEAL
7/17/2019 Gulf Tunneling Company Profile
http://slidepdf.com/reader/full/gulf-tunneling-company-profile 43/54
A steel launch seal, coated in flexiblepolyurethane foaming agent, will befixed onto a concrete eye properlylocated on the launching shaft wallface. The cutting head starts its boringat precisely that specified location. Thepurpose of the seal rubber is to preventany injected materials and fines fromcoming through the opened boundary.
2.8 INTERJACK STATION
Interjack stations are used for long distance pipe jacking to move the pipeline in separate sections. The skin friction rein feed resistance is divided by the number of interjack stations; consequently, the allowed jacking force of the pipe wbe exceeded.
The position and number of interjack stations in line are subject to change, depending on the soil conditions. Thinterjack station is installed at a distance of approximately 50m behind the machine with subsequent stations instaapproximate distances of 150m.

Directional boring, commonly called horizontal directional drilling or “HDD,” is a steerable trenchless method of installing underground pipes, conduits, andin a shallow arc along a prescribed bore path by using a surface-launched drilling rig, with minimal impact on the surrounding area. Directional boring is usedtrenching or excavating is impractical.
Directional boring minimizes environmental disruption. It is suitable for a variety of soil conditions and jobs including road, landscape, and river crossings. Insta
lengths up to 2,000m have been completed, and diameters up to 56” (1,200 mm) have been installed in shorter runs. Pipes can be made of materials such as Ppolyethylene, ductile iron, and steel, as long as the pipes can be pulled through the drilled hole.
Directional boring is used for installing infrastructure such as:
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,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 damaexisting utilities, however; so, the HDD method necessitates that the operator has complete information about the existing utilities so that he plans the whole alignma way that prevents any damage to them. Different government agencies have established legislation to ensure safe work execution and to authorize such work inenvironments. Different trenchless-technology promoting organizations have developed guidelines for this technique in order to standardize of the techniques.
