4. INTRODUCTION
PHASE I
North-South(15.5 kilometers)
East-West (13.5 kilometers)
Totaling nearly 30 Kilometers, will be laid across the city at
an estimated cost of Rs 8,000 crores.,
The East-West corridor will be from Ramganj to Mansarover,.
A nine-km elevated track connecting Chandpole to
Mansarover be the first to be completed
The North-South corridor will connect Sanganer to Panipech

5. NEED OF METRO SYSTEM
Population growth rate of Jaipur is double the
average growth rate of other cities.
Significant reduction in environmental pollution.
Development of Delhi-Mumbai Industrial Corridor,
SEZ, International hub for Gem & Jewellery &
increasing tourist inflow will put additional burden
on transportation need.

6. ADVANTAGE OF METRO
SYSTEM
Metro systems are superior to other modes because
they provide higher carrying capacity, faster,
smoother and safer travel, occupy less space, are
non-polluting and energy-efficient.
Causes no air pollution in the city.
Causes lesser noise level.
Reduces journey time by anything between 50%
and 75% depending on road conditions. 6

7. READY MIX CONCRETE
Ready-mix concrete is a type of concrete is manufactured in
a factory or batching plant.
TRANSIT MIXTURE
The cylindrical portion is continuously rotating.
The rotation speed of cylindrical portion is 0-14 rpm.

16. PILE CAP
A pile cap is a thick Concrete mat that rests on concrete
or timber piles that have been driven into soft or
unstable ground to provide a suitable stable foundation.

17. PIER
Grade of Concrete M- 50
The Diameter of Pier is 2000 mm from Ground level to
Concourse level and from Concourse level it is 1600
mm.

19. CRASH BARRIER
It is constructed around the pier to avoid the direct impact
on the pier in case of accident. The thickness of crash
barrier is225mm and consist 25mm cover. The height of
crash barrier is 165mm.The grade of concrete use in crash
barrier construction is M-35.
19

20. DRAINAGE
The drainage pipe is used for drain the rain water from
track level.
The diameter of drainage pipe is 200mm.
For the drain of water a drain hole is also construct in
the crash barrier.

22. CANTILEVER PIER ARM
A pier is consist 2 pier arms at Concourse level.
M -55 grade concrete is used.
The size of one arm is 10230 mm from center of the pier.
The depth of pier arm at near to the pier is 2250 mm and at
end point is 1650 mm.

24. PRECAST GIRDER
They are precast at casting yard or on site.
The girders are placed on the corbel.
The sizes of girders are 350 mm X 1200 mm.
 Grade of concrete is M-50.

26. PRECAST SLAB
The dimensions of precast slab are 165 mm X 1000 mm.
The concrete grade is M-35.
The slabs and girders are jointed each other by arc welded
connection.

27. LAUNCHING OF PRECAST
GIRDER
HYDRA DEMAG HC-400” is used to launching or
Erect the Precast Slabs and Precast Girders on
Pier Arms.
Firstly Hydra must be stand on hydraulic jack.
 The capacity of this crane is about 150KN.
The Capacity of Hydra is Depend on its Boom
Length.

29. PROBLEM AT SITE
Allowing free flow of vehicular traffic on the already
congested along with chosen alignment.
Paucity availability of Land.
Existence of charted and uncharted utilities.
Problems to pedestrian.
Problems to existing residents.
 Environmental Impact including noise and vibration etc. 29

30. SAFETY
Safety is very important thing for any kind of
construction.
 The safety is for workers as well as for public also.
 The safety belts, helmets and Safety shoe is used,
without these things, the entry to the site is
prohibited.

32. CONCLUSION
Such types of construction actually is very
difficult.reduce the traffic volume, travelling time .
Summer Training is a golden opportunity for
learning and self development and really
experiencing the real scenario of the company
environment. It helped me to increase my
technical skills. It is also helped me to be with
latest and new technologies.
