EXTENDING THE DELHI METRO SYSTEM, DELHI INDIA

Using post-installed rebars to mend cast-in rebars

The challenge

The Delhi Metro aims to change the way people travel not just in Delhi, but in the whole of India. Its sleek, shiny and air-conditioned trains are heralding a “new era” as it says, of mass urban transportation in the country.

And it’s setting its sights high – aiming to have the highest number of stations with the longest metro system in the world, even surpassing London’s 150 year old tube in length, all within just a few years.

It’s now going through Phase III of its expansion.

But while building at the Nehru Palace metro station, it hit a snag. Some of the steel couplers became misplaced during building, and we were brought in to see what could be done.

Our Hilti solution

The solution was to install post-installation reinforcement bars to give the structure more support and substitute the misplaced rebars.

We found that our Hilti HIT-HY 200-ft chemical adhesive was a good fit to fix in the post-installation rebars needed.
