Our project is successful due to the effort of those people who have given their valuable time and advice.We sincerely appreciate the inspiration,support and guidance of all those people .

We,the student of “NARULA INSTITUTE OF TECHNOLOGY“ are extremely thankful to “GAMMON INDIA LTD“ for giving us the opportunity to practically experience their metro project at site.

At this juncture we feel deeply honour in expressing our sincere thanks to Er.Kousik Rakshit sir,Er.M.Haque sir,Er.Bittu Bawalisir,Er.Arghya Das sir,Er.Partha Chakraborty sir,Er.Abhinav Chatterjeesir for making the resources available at right time and providing valuable insights leading to the successful completion of our project.

I would also like to thank all the faculty member of NARULA INSTITUTE OF TECHNOLOGY for their advice and guidance without which this project would not been possible.

SUBJECT:PARAPET CASTING(SITE:NEAR TECHNOPOLIS)

PARAPET :It is a structural member which is fix over the segment. As a technical view, parapet basically used for walk way for maintenance and surveillance and also used for cable transmission. Parapet also gives beautification of the structure.

MATERIAL USED IN PARAPET MAKING :Two different Dias of rods (8mm & 10mm) are used for parapet reinforcement and M40 grade of concrete is used for this structure.

Reinforcement of Parapet-

Steel of SAIL and RVNL is used as reinforcement,

PROTMAX inhibitor solution is used as an

anticorrosive treatment with cement slurry which is applied on the rod.

Bed-

Bed is that on which the parts of reinforcement are joined together by diamond binding. Bed is fabricated by M.S Plate, Rubber Pad & G.I member.

Concreting procedure -Parapets generally concreted on the bed, with a concrete

of particular w/c ratio required. In some case vibrator is

used at the time of concreting to ensure zero void inside.

Admixture-

In case of parapet casting STRUCTRU 201admixture is used for increasing the workability.

Part of Parapet Structure –

Parapet structure mainly consisting of three parts-(generally)

Walk Way (0.179 sq.m) Web(0.188 sq.m) Parapet Bottom(0.141 sq.m)

SUBJECT:SEGMENTCASTING

(SITE:NEAR MANI SQ) BASIC STEPS OF SEGMENT CASTING:1)ROD BENDING(according to drawing)2)Rod binding 3)Placing of rod cage into bed.4)Shuttering.5)Concreting and Curing.

STEPS OF CONCRETE MIX DESIGN :

According to IS 10262:2009

STEP 1 : Target Strength for Mix Proportioning

STEP2 : Selection of Water-Cement Ratio

STEP3 : Selection of Water Content

SETP4 : Calculation of Cementitious Material Content

STEP5 : Estimation of Coarse Aggregate Proportion

STEP6 : Combination of Different Coarse

Aggregate

Fractions

STEP7 : Estimation of Fine Aggregate Proportion

STEP8 : TRIAL MIXES

We have learnt so many things about kolkata metro project from the respected site engineers.

We want to say thanks to the engineers to spend their valuable time with us.

They energized us for this work.
