Pier Construction in Flyover or Metro Viaduct Construction

By

                               Pier Construction :

          Pier is a substructure of viaduct that is supported by closely spaced piles and transfers all the loads from superstructure to ground through pile foundation.
          Two types of piers are used in the project :
1.    Station pier (square)
          Dimensions being 2400 mm x 2000mm.
2.    Eccentric pier (viaduct)
          Diameter of eccentric pier is around 1.8m.

Methodology :
1.    Vertical Reinforcement are aligned and supported with concrete blocks.
2.    Other reinforcements like rings and link rods are then tied according to design and bar bending schedule.
3.    Vertical alignment is assured by plumb bob and coordinates.
4.    Self Shuttering is placed with a cover of 75mm.
5.    M40 grade with slump of 160 - 175mm concrete is poured is compacted using needle vibrators.
6.    It is cured by watering and covering by wet cloth.

                                          Girder ●       Girder is the superstructure of viaduct on which the rail tracks are laid and train runs. ●       It rests on the piers, one at each end. ●       Since we have two tracks, each pier supports four U girders (two on each side) ●       U girder weighs around 140 Tons and is 25 m long. There are 3 bed in the Casting Yard for both U girders and pier cap – • Caging Bed • Casting Bed • Curing Bed Each Bed is Capable of Making four Girders simultaneously in a row. Methodology : 1.     Four Cages are fixed at the Cage Bed. 2.     Cleaning And Oiling of Mould/Shuttering of Casting bed is done. 3.     Lifting Of Cage and Shifting to Casting Bed is done. 4. ...

It allows human body to exercise all the body parts easily. In my opinion Mallakhamb is the only sport which anyone have to starts from the infant age because at this age the muscles are more flexible and it helps in exercising easily.

 Mumbai- Ahmedabad High Speed rail Project - A dream of many Indian Citizens. I think I’m enough competent to answer this question as in recent workshop with the Industry experts from Germany, Italy, Singapore, Japan, Thailand and Malasiya organized by Asian Development Bank Institute we have analysed the most potential high speed rail routes in India and overseas and discussed on various parameters like Economic benefits, Environmental aspects, Challenges, stakeholder management, Engineering aspects, Multi-modal Integration, Asthetics, Reduction in Carbon footprints etc. I can share one of the snap of the discussion. In the discussion, We have reviewed many reports on different high speed rails like Shinkansen, Intercity express, Trains à Grande Vitess, Alta Velocidad Española etc. Experts have come to the conclusion that the most competitiveness of HSR is high in distance from 500–700 km when compared to other modes of transportation like air, road etc while connecting two major ...
