KARCHAM WANGTOO

INTRODUCTION• Himachal Pradesh is the INDIA’s gateway to the Himalaya

region and key to unlock energy problem.• run-of-the-river hydroelectric power station on the Sutlej

River in Kinnaur district of Himachal Pradesh, India. • Jaypee Karcham Hydro Corporation Limited of JSW Group

signed a memorandum of understanding to develop the dam in 1993 and after years of delays, construction on the power station began on 18 November 2005.

Location of dam• The dam is

located at 31°30'N, 78°10'E

• located between the villages of Karcham and Wangtoo

Construction of dam• The all work is carried

out by the Jaypee group.

Amazing fact…• Large amount of cutting and filling need to establish the

base camp• 1 year time is required to construct base camp for 14500

people• 541 m divergent channel constructed for diverting water

to river

Construction

• construction on the power station began on 18 November 2005.

• The first generator was commissioned in May 2011, the second in June and the final two in September.

• Two coffer dam are constructed first and a divergent tunnel is constructed to divert water

Challenges for the work• Weathering conditions• No electricity facilities• Road are not available to rich site• Removal of excavated material from site• Leakage of cofferdams and cement grouting• Sedimentation of particles in water• Construction of head raze tunnel• To establish transmission line up to Haryana

DR. K.K.satiChief project geologies

• We made corning hole through a core drilling machines

• We found sound rock profile at 52 m depth for dam

• Actual depth of foundation measured after construction is 53 m

Vipin Kumar(Vice president of Jaiprakash power ventures Ltd)

• Removing excavated material is major challenge

• 6 wheel drive articulated dumpers imported by Volvo

• The truck carries up to 37 tone material at a time

• Huge amount of cement grouting needed for coffer dam

Sanjay gupta(dam site incharge)

• The cement grouting get damage and water comes to the main site

• If coffer dam damages and water comes in site the we will lack schedule up to 1 year

• Every one is there “top to lower management”

• “the present of all management feels something different and give total satisfaction”

• We used truck and damp boulders over cofferdam and make new trance drainage to remove water

Ashish bajaj Project manager

• Sedimentation is big problem in plant

• 2mm particles can stop the power plant

• Water comes in sedimentation tank in 4.1 m/s speed and reduces up to 3 m/s

• 53 no of hoppers are provided to remove this particles

• 504 m3/s water can discharge through channel

• World’s largest chamber volumetrically and get chance to place in Guinness book of world record

• Length : : 424 m • Depth : : 35 m• Width : : 80 m

Ashish bajaj Project manager

• Head raze tunnel : : 17 km long• Velocity of water : : 4.8 m/s• Diameter of tunnel : : 10.5 m

• Construction of tunnel

• Drill holes up to length of 4 m

• Charge the explosives

• 3 m depth at every fire

DR. M.M.SinghSr. principal scientist ,CIMFR

• Extreme steam comes to the rock and site converts in to the presser cooker

• We did thermal scan of site

• The temperature found in site is about 60 to 98 c

• No one can work in at site time line going dead

Samrender kumar The mountain driver,SR. project enginner(civil)

• we are working on the solving problem

• I found a alternative that spray cool water on the rock and simultaneously do the wok

• Built of shaft vertically down and serge tank is big problem for me because of,

• There is no road to get site• We have to climb mountain abut 1080 m

to reach site

Ashish bajajProject manager

• EDT crane large equipment used in project

• In the first time we design a profile on the rock and put the rail of EDT crane on the profile directly

• The grate achievement got by survey team of construction group

• It saves time of erection and fabrication.

Ravinder singh,G.M. transmission line,Jaypee power grid Ltd.

• Toughest site in India to work in my career

• 270 km long transmission line up to Haryana

• 5000 transmission tower built by hand

• 50 tone material required to built a single tower

• Wire, cables and other tools transporting manually

• 30 tone of erection of bolt done manually

• 7000 workers work together for 253000 tone work

It is 11th five year project of INDIA

• 1st chapter of Himalayan megastructure is over • It help to produce 1000 GW power for consumptive people

of INDIA• It is joint mission of man – money – machine – nature.
