While carrying out excavation work the excavated material/earth shall be placed at
least 3 meter away from the trench edges or ½ of the trench depth, whichever is more.
All excavated material shall be stacked in such a manner that it does not endanger the
work and avoids obstructing laying works. Natural water courses shall not be
obstructed.
During construction work if it is necessary to close the road, suitable signs indicating
that a road is closed shall be placed and necessary diversion signs for proper
maintenance of traffic shall be provided.
Temporary support, adequate protection maintenance of all underground and surface
structures, drain, sewers and other obstructions encountered shall be provided.
Trees, shrubbery fences and other properties shall be protected unless their removal is
shown in the drawing. Where trees have been cut, the tree roots within a distance of
half meter from the side of the pipeline shall be removed or killed.
A minimum clearance of 150 mm shall be provided between the pipeline and such
services.
3. INSPECTION
The alignment of the trench will be checked as per the survey drawing.
4. BEDDING
When rock or boulders are encountered, the trench shall be trimmed to a depth of at least
300 mm below the level at which the bottom of the barrel of the pipe is to be laid and filled
with non-comprising material like sand to give curved seating.
The class of bed and surround to be used are indicated Below
Class of Bed Description of bedding
Class A Mass Concrete
Class N Well Graded
Class S Granular materials
The concrete to be used for Class A bedding and surrounding shall be M15. Class A
bedding shall be used at all road crossings under the road and for a distance of 5M back
from the back edge of road or foot path. Concrete shall not be placed until the pipes are
jointed, inspected and tested. Before placing concrete the pipes shall be supported near
each joint a padding of compressive material on a Pre cast concrete block. The concrete
shall be placed to ensure full contact with pipe barrel through out its length.
Class N bed materials shall only used where the pipe trench is found hard rock or other
wise as directed by the engineer.
The graded granular bed materials for use in Class S bedding and surrounding shall consist
of durable gravel crushed stone dust or disintegrated rock. All Class S graded materials
shall pass through test sieves to IS 460 (part1). The granular materials shall be evenly

required minimum cover of 1.2 meter above the top of the pipe,
d) Trench shall be adequately widened at bends before hand to avoid tension in pipe
section while lowering.
e) Where water is present in the trench, no laying shall be permitted. The pipe shall be
laid after complete dewatering of the trench.
f) Pipes shall be laid in trenched on suitable supports such as sand bags to facilitate
the welding and coating of the field joints.
g) Pipe laying shall be carried out with help of shear legs or cranes using belts or
slings covered with suitable non- abrasive material, to ensure that no damage is
done to the coating of the pipe.
h) At first two pipes shall be laid. After completion of the circumferential welding
further laying operation shall be started.
i) Where the trench is sheeted, the pipe shall be lowered into the trench by removing
at a time one or two struts only. Care shall be taken to ensure that no part of the
strutting is disturbed or damaged. If necessary additional struts may be fixed
during lowering.

IS 11906 & CLIENT Specifification
MATERIAL
a. Ordinary Portland Cement conform to IS- 8112
b. Aggregate conform to IS 11906 Table – 1
c. Water as per requirement of IS 456.
METHOD:
The inside of the pipe shall be cleaned to remove all rust, chemical or other deposits, loose
mill scale and remains of old materials by chemical or mechanical (power Driven cleaner)
means to the approval of the Engineer. Immediately prior to the travel of the lining machine
through pipe line, all foreign materials to be removed.
Cement mortar in the proportion of cement and sand shall be applied 1:1.5 to such a
consistency so as to produce a dense and homogeneous lining that will adhere firmly to the
pipe surface. The cement mortar mix shall comply with strength and density requirements
specified in IS 11906.
The lining thickness shall be in 14mm with a negative tolerance of 1mm and with a positive
tolerance of 3mm.
In-situ Lining method is done in one course by hauling the machine with constant speed
through the pipe and the mortar is spinned against the inner pipe surface by an electric-
driven, fast-rotating centrifugal discharge head. The rotating trowels mounted on axially
aligned arms behind the centrifugal head are pressed with a certain spring tension against
the mortar surface granting a smooth finish. The service lines for electricity and mortar are
pulled through the pipeline by means of a winch whose speed is adapted to the operating

speed of the lining machine. The otherwise automatic operations performed inside the
pipeline are monitored by a machine operator.
The electric propelled lining machine mounted on pneumatic tyres passes (at constant
speed) through the pipe at (a constant speed).
The lining machine is equipped with a funnel-shaped hopper serving as intermediate
storage for the cement-mortar pumped through the pumping hose towards the machine. A
conveyor screw then forces a constant amount of mortar from the hopper to the
centrifugal head (Consequently), the selected traveling speed of the machine determines (in
consequence) the thickness of the layer.
Steel finishing towels shall be used for hand application except at bends. All hand finishing
work in a section of the pipeline shall be completed within 24 hrs after completion of the
machine application of mortar lining to that section. After completion of the mortar lining
and hand finishing of a section of pipeline curing shall commence immediately. Curing
should not later than 8 hrs after mixing of mortar. The lining shall be kept continuously in
moist condition for a period as per IS code and as per specification of Employer.
Strength:
The compressive strength of cement mortar shall be 25 N /mm2
