TBM S53 Makes a Breakthrough at Lucknow Metro’s Hussainganj Stn

Back on December 12, tunnel boring machine (TBM) S53 “Ganga” operated by the Tata – Gülermak JV made a successful breakthrough at Lucknow Metro’s Hussainganj Station on the 22.88 km Line-1’s 3.44 km underground section between Charbagh and KD Singh Babu Stadium.

After completing the Sachivalaya – Hazratganj section’s up-line tunnel in August, the Ø6.52m Terratec manufactured TBM was retrieved, transported and re-commissioned from Sachivalaya Station in early October, and took only 2 months to build the 613m up-line tunnel – its 2nd of 3 tunnels, aided by local geology which consists of stiff to hard clayey silt and medium to dense silty sand.

With this development, 4 out of 6 tunnels are now structurally ready.

In mid-January & early February 2018, both S52 and S53 were recommissioned one after the other from the Charbagh Ramp towards Hussainganj to build their final tunnels (roughly 446m each). This deviates from the original tunneling plan in which the TBM would have continued southward after being dragged on rails across Hussainganj’s platform level by hydraulic jacks.

Progress as of February 8 (1 ring = 1.4m)
• TBM S52 (Gomti) – 59 rings completed
• TBM S53 (Ganga)- 3 rings completed

      I see it opening sometime in 2019 along with the 8.63 km KDSB – Munshipulia section further north. Testing will be definitely begin by the end of this year.

    I due tunnel verranno scavati impiegando due TBM EPB da 9,77 m di diametro, capaci di sostenere il fronte di scavo con la contropressione del terreno già scavato.
