2.4 Information About Microtunneling
Microtunneling is a trenchless construction method used to install pipelines beneath
highways, railroads, runways, harbours, rivers, and environmentally sensitive areas.
Microtunneling is defined as a remotely-controlled, guided, pipe-jacking operation that
provides continuous support to the excavation face by applying mechanical or fluid pressure
to balance groundwater and earth pressures. Support at the excavation face is a key feature of
microtunneling, distinguishing it from traditional open-shield pipe-jacking.
Microtunneling requires jacking and reception shafts at the opposite ends of each drive. The
microtunneling process is a cyclic pipe jacking operation. A micro tunnel boring machine
(MTBM) is pushed into the earth by hydraulic jacks mounted and aligned in the jacking
shaft. The jacks are then retracted, and the slurry lines and control cables are disconnected. A
product pipe or casing is lowered into the shaft and inserted between the jacking frame and
the MTBM or previously jacked pipe. Slurry lines and power and control cable connections
are made, and the pipe and MTBM are advanced another drive stroke. This process is
repeated until the MTBM reaches the reception shaft. Upon drive completion, the MTBM
and trailing equipment are retrieved, and all equipment removed from the pipeline.
Most microtunneling operations include a hydraulic jacking system to advance the MTBM
and pipe string, a closed loop slurry system to transport the excavated spoils, a slurry
cleaning system to remove the spoil from the slurry water, a lubrication system to lubricate
the exterior of the pipe string during installation, a guidance system to provide line and grade
control, an electrical supply and distribution system to power equipment, a crane to hoist pipe
sections into the jacking shaft, and various trucks and loaders to transport spoil off site.
MTBMs have a rotating cutting head to excavate the ground material, a crushing cone to
crush larger particles into smaller sizes for transport through the slurry lines, a hydraulic or
electric motor to turn the cutting head, a pressurized slurry mixing chamber behind the cutter
head to maintain face stability, an articulated steering unit with steering jacks for steering
corrections, various control valves, pressure gauges, flow meters, and a data acquisition
system. Additionally, the MTBM has inline cameras to relay information to the operator and
a target system for guidance control. Precise control of line and grade is accomplished using
the guidance system and steering jacks to locate and steer the MTBM during a
15. 15
microtunneling drive. The guidance system usually consists of a reference laser mounted in
the jacking shaft, which transmits a beam onto a target mounted inside the articulated section
of the MTBM. This and other operational information is transmitted through wire cables to a
control cabin located on the surface.
Microtunneling machines are capable of independently counter-balancing earth and
hydrostatic pressures. Earth pressure is counter-balanced by careful control of advance rates
and excavation rates of spoil materials. Groundwater pressure is counter-balanced by using
pressurized slurry in the soil-mixing chamber of the MTBM.
2.5 Open-cut vs Microtunneling
Figure 4 Open-Cut Vs Microtunneling
16. 16
Because the microtunneling procedure involves a remotely-controlled steerable system to
install pipes and cables at the ground surface, it only requires a small tunnel boring machine.
As opposed to traditional open cut construction which can be destructive to the surrounding
site, microtunneling allows for a much more direct route.
Microtunneling techniques offer advantages over traditional open cut construction and
therefore, have become the primary means of underground construction methods.
Microtunneling is said to be one of the most beneficial underground construction techniques
for everyone involved and the surrounding environment.
The microtunneling method is very friendly on the environment because of its cleaner
process. Techniques used in the microtunneling and pipe jacking process ensure quantities of
both incoming and outgoing materials are reduced significantly. Not only is this less harsh on
the surrounding environment, but it boosts the safety benefits for the workers too.
Combined with pipe jacking techniques, the microtunneling method is one of the most
environmentally friendly and safer underground construction process. Because open cut
trench construction normally has to follow existing pipe utilities, roadways and other
unobstructed surface, microtunneling offers a trendless construction that protects the
environment rather than destroys it.
Microtunneling processes have proven to be an advantageous and practical method that not
only reduces environmental risks, but project costs too.
The risk of injury to workers and the general public are reduced by using methods such as
microtunneling with more accurate systems still being achieved.

CHAPTER 3: PROJECT EXECUTION WORK
3.1 Planning
The first consideration is determining the pipeline line and grade. This may sound simple but
locating the position of your pipeline requires an intimate understanding of the ground
conditions, and the microtunneling equipment and its capabilities, in order to save costs and
avoid problems during construction. Following is some advice in planning your line and grade:
Seek local knowledge of past construction projects. If you can obtain previous documents
from projects completed near the proposed site, you are that much ahead in getting started on
planning the line and grade of your project.
Physically establish a line of sight between shaft locations. Sometimes you can identify
obstructions like a bridge support pier or sheet pile wall along the proposed tunnel route.
Beware of existing utilities and service manhole inverts that “straddle” the tunnel route.
Therefor essential elements of planning are,
Gather information about past projects in that area.
Identify existing subsurface utilities and manholes.
Establish a sightline between shafts.
Data collection.
Lab testing.
Geotechnical investigation

3.2.4 Tests Performed
3.2.4.1 Three Edge Bearing Test
The external load crushing strength test with the load applied by three-edge bearing is the
accepted test method for both clay and concrete pipe. This same procedure may be employed in
the testing of concrete pipe if it is mutually agreed upon by the manufacturer and purchaser prior
to testing. Any mechanical or hand-powered device may be used in which the head that applies
the load moves at such a speed as to increase the load at a uniform rate of approximately 20
percent of the expected crushing load per linear metre per minute. The loading device shall be
calibrated within an accuracy of ±2 percent. The testing machine used for the load tests should
produce a uniform deflection throughout the full length of the pipe and shall be so substantial
and rigid throughout, that the distribution of the test load along the length of the barrel of the
pipe will not be appreciably affected by the deformation or yielding of any part of the machine
during the application of the load.
Figure 7 Three Edge Bearing Test
23. 23
3.2.4.2 Hydro Test
Hydrostatic testing is a type of pressure test that works by completely filling the component with
water, removing the air contained within the unit, and pressurizing the system up to 1.5 times the
design pressure limits the of the unit. The pressure is then held for a specific amount of time to
visually inspect the system for leaks. Visual inspection can be enhanced by applying either tracer
or fluorescent dyes to the liquid to determine where cracks and leaks are originating.
Figure 8 Hydro Test
3.2.4.3 Water Absorption Test
Cement will mix with more water than is required to eventually combine during hydration of
cement paste. As such, some voids will be left behind after the hydration process which affects
the strength and durability of concrete. With the presence of air voids in concrete, it is vulnerable
to penetration and attack by aggressive chemicals. Good quality concrete is characterized by
having minimal voids left by excess water and therefore, water absorption test for precast
concrete pipes is adopted for checking the quality of concrete in terms of density and
imperviousness.

3.3 Site Execution
Major Execution work can be sequenced as below:
Shaft construction by sinking method
MTBM lowering and launching
Pipe jacking
MTBM receiving
3.3.1 Shaft Construction
Shafts should be capable of withstanding pre-determined jacking loads required to propel the
MTBM over the tunnel drive length and facilitate safe entry into the ground and exit out of the
ground.
3.3.1.1 Trial Pit
A trial pit is an excavation of ground in order to study or sample the composition and structure of
the subsurface, usually dug during a site investigation, a soil survey or a geological survey. Trial
pits are dug before the construction. They are dug to determine the geology and the water table
of that site. Trial pits are usually between 1 and 4 metres deep and are dug either by hand or
using a mechanical digger.

3.3.2.2 Set up and Lowering of MTBM
The equipment is set up at and around the shaft in the pre-determined arrangement for the drive.
The tunnelling machine is set up at ground level and connected up to the control container and
services. A series of test run are then carried out to determine that all equipment is functioning
correctly, and the drive parameter entered into the computer program. The services are then
disconnected, and the tunnelling machine is lowered into the shaft in preparation for jacking.
Mobile crane or gantry crane of suitable capacities are commissioned over the jacking shaft prior
to lowering of machine. A laser theodolite is placed to guide and monitor the alignment of the
jacking line.

3.3.2.3 Important Points to be Consider for Jacking
Before any particular pipe jack length commences sufficient number of standard, lubricating
pipes and intermediate jacking assemblies shall be ensured for continuous operation
Suitably designed RCC pipes are to be used
The jacking force applied by the thrust pit jacks or an intermediate jacking station shall not
exceed the design allowable distributed or deflected load for any pipe being jacked
Pipe jacking, once commenced shall be performed as one continuous operation until
completion.
A lubrication or ground support fluid, such as bentonite, shall be injected into annulus
between the exterior of the pipe and the ground. This fluid shall be maintained till end of
jacking for the span.
3.3.2.4 Jacking Sequence
The shield is jacked until there is sufficient space for the first jacking pipe to be installed
The shield machine and slurry pumps are then stopped, and all electrical cables and slurry
lines are disconnected in the jacking shaft
The jacks are retracted, and all spacer removed in order to make space for the jacking pipe
The jacking pipe is lowered into the shaft and placed on the guide rail
After ensuring the pipe is joined properly to the tail of shield machine, the electrical cables
and slurry lines are reconnected
Jacking of pipe is then resumed and the whole process is repeated until the shield machine
reaches about 300 mm from the face of the receiving shaft
The exit ring and rubber seal are fixed if required depending on the ground water table
Demolish concrete wall & reinforcement in front of the soft eye and jacking operation
resume until the whole shield machine is driven into receiving shaft
The shield machine is removed, lifted up and transferred to next jacking shaft for
maintenance and to commence another line
The jacking pipes are advanced to their final position and the alignment, gradient and levels
reconfirmed
Upon completion of jacking the entire pipeline should be cleaned and repaired if required

The completed pipeline is then visually inspected
During jacking, the alignment of the pipes is constantly checked by means of the laser
theodolite and laser target. Alignment corrections can be made using the steering jacks
situated in the shield machine
Jacking force is monitored closely during jacking operations, bentonite slurry is pumped
through the grout holes in the jacking pipes to lubricate and reduce the frictional forces at
interface of the outside circumference of the pipe and the surrounding soil
In long span where jacking operations cannot be completed in a day, the alignment and
gradient of the laser targeting system is checked time to time against the survey reference
points, prior to commencing pipe jacking. The survey reference points are also checked
against other survey control as and when required

3.3.2.5 Spoil Removal System
The spoil removal system consists of counter flow unit, a charge pump, a pit by-pass unit, a
discharge pump, a flow meter, slurry tanks and slurry lines
The bentonite-based slurry is mixed at the slurry tanks and pumped to the work face through
the cutter head of the slurry shield via the pit by-pass unit installed in the jacking shaft
Spoil that has been excavated by the slurry shield machine is pumped through the discharge
line to the slurry tanks of the surface. The spoil is separated in the slurry tanks and the
remaining slurry is charged again to the slurry shield machine. The settled spoil in the tanks
is removed
Since the slurry lines extend as the shield advances, it is essential to keep a certain level of
the flow rate to ensure the effective conveyance of the spoil. For this purpose, a flow meter is
fixed to the discharge line to detect and transmit the slurry flow rate to the operation board.
The slurry is also used to balance the ground water head, which is detected by the cutter face
pressure gauge in slurry shield machine. The slurry pressure applied to work face is
controlled by the pressure control valve of the pit by-pass unit in the jacking shaft
The muck is pumped from the shield face to the sedimentation tanks at the top of the jacking
shaft. The solids are then removed from the sedimentation tanks and disposed off site
3.3.2.6 Removal of Equipment
When the head of the machine enters the receiving shaft, it is tools apart into two sections and
removed from the shaft using a mobile crane. The intermediate jacks are dismantled, and the
pipeline is pushed to its final position and tunnel eyes at each shaft are grouted with concrete or
sand cement grout and the entrance seal is removed.

3.3.2.7 Finishing Works
After completion of all inside manhole works RCC top slab as per approved drawing will be
casted along with extra heavy-duty manhole cover frame monolithically. The manhole frame will
project 25 mm above slab top. Necessary staging / shuttering will be done with support from the
steining walls. Staging and shuttering will be removed after 21 days i.e. after slab attains its full
strength. Bitumen carpeting will be applied on top slab expect on manhole cover area. It is
essential to avoid construction of manhole between shafts with in carriage way unless extremely
necessary.

CHAPTER 4: CONCLUSION
4.1 Conclusion
The training is a bridge between the theoretical knowledge and the practical or the reality work
at the field of construction or civil engineering work. I can conclude from my eight weeks of
training period that there was a great difference and bifurcations observed between the
theoretical aspects that I am taught about in the classes and the practical work aspects seen over
the construction site. As there is ample amount of scope for understanding much more when
practically experienced on the ongoing construction site. I achieved more knowledge in such
situation; while I had my endeavour over the practical work in that construction ambience around
me. I even observed that construction management was the most necessary subject on field
because there had been limited labours available and work was much more plus lots of restriction
and specifications were to be observed while working but if work in any case such as due to not
following the specifications written in the contract or the tender and etc. may be cause for
termination or deterioration in the working plan and schedule for the contractor resulting in
mismanagement over the site causing delay and even other great losses which were to be
experienced for both the firms that is the contractor and the client. Hence presence of mind and
human resource management with effective communication is necessary skills over the site.
Some of the benefits that I gain during training program are:
• Upgrading of theoretical knowledge and able to use it for practical work.
• Developing of communication skill.
• Developing skill of team work.
• Improving personal ethics and knowing work ethics.
• Being able to do different tasks.
