CREG designed and manufactured a Ø10.5m EPB TBM with active articulation and 180m horizontal radius curve turning capacity to satisfy TBM deviation correction and direction adjustment during tunnelling for Algiers Metro Project, Algeria. This was China’s first TBM exported to the African continent.

The TBM was used for the construction of Algiers metro extension line from Al Harrach Central Station to Huari Bumaiding Airport Station. With a total length of 9,565 meters, this tunnel will greatly enhance the passenger throughput of the airport and shorten the transit time from Algiers city to the airport.

The TBM celebrated its FAT in Tianjin, China on the 15th of January 2019 and started to bore the tunnel on the 8th of January 2020.
