NEED OF METRO SYSTEMPopulation 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.

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
READY MIX CONCRETEReady-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.

PILE CAPA 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.
16
PIERGrade 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.
17
PIER
18
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
DRAINAGE
The drainage pipe is used for drain the rain water fromtrack level.
The diameter of drainage pipe is 200mm.
For the drain of water a drain hole is also construct inthe crash barrier.

CANTILEVER PIER ARMA 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.

PRECAST GIRDERThey 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.
24
PRECAST GIRDER
25
PRECAST SLABThe 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 weldedconnection.
26
LAUNCHING OF PRECAST GIRDER
HYDRA DEMAG HC-400” is used to launching orErect the Precast Slabs and Precast Girders onPier 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.

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
SAFETYSafety 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 isprohibited.

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.
