Mumbai Metro Line-2B: MMRDA completes the concrete casting of the Shunya Iconic Cable Stayed Bridge

The Shunya Iconic Bridge is a cable-stayed bridge that is under construction to support the Metro Line-2B Viaduct crossing Vakola Nalla. This extensive bridge accommodates a length of 130 metres in total, with 80 metres of the same solely dedicated to the long main span across Vakola Nalla.

More Details:

  • The remaining 50 metres of the length corresponds to the anchor span.Today, a huge pile cap has been cast for Shunya Iconic Bridge at P478. This event marks a major progress in the construction of this elegant bridge.

  • The measurements for the Pile Foundation Cap are 20.59 m x 11.979 m x 3 m. The concrete quantity of the pile cap is about 670 cubic metres, and it is with a reinforcement of about 197 metric tonnes including pedestal about 45 metric tonnes. 75 Dia VSL 835/1035 threaded stress bars (FFT Bars) were chosen for being embedded with the pile foundation cap. The FFT bars are 120 in number, and their utilisation reinforces the pylon base to greater proportions.

  • MMRDA has taken effective measures to maintain optimal temperatures using concrete temperature monitoring. Temperature monitoring devices and sensors are embedded across the pile cap on three different levels, categorised by the aspect of depth.

  • The concrete temperature monitoring system oversees the rises and falls in temperature, while cold water and ice flakes are employed to mitigate the effect of heat on concrete.
  • Water sprinklers are used to maintain the transit mixers in a wet state, while hessian cloth is used to cover the same. The methodical incorporation of planned activities alongside the unwavering dedication of the construction teams is leading to steady and significant progress.
