TBM La Carolina completes its journey for the Quito Metro

On the 19.06.2018  TBM La Carolina reached the end of its underground journey after boring 3.55 km of tunnel and installing 2,281 concrete rings for the Quito Metro. The TBM began the excavation works in June 2017, at Solanda station and it reached its first station, Moran Valverde, in January 2018 after constructing 1.9 km of tunnel, where it underwent maintenance and upkeep work to continue its final journey to Quitumbe station.

The three TBMs, involved in the construction of the Quito Metro line 1, have completed 74% of the tunnelling works, 15.39 km of the total tunnel construction.

The overall project is 67% complete, with 73 action points between stations and supplementary works, such as ventilation shafts, emergency exits, terrain preparation prior to the arrival of the TBMs, and station accesses. To date, the foundations have been laid at 13 stations, and spaces on the surface that have been used to build the metro are being gradually returned to their previous use.

The future line 1 of the Quito Metro, which is being built by Acciona, who will have 22.6 km of tunnel and 15 stations to finish. Click here and ec/19 for tunnelbuilder archive. Visit http://www.metrodequito.gob.ec.  27/18.
