China Gezhouba Group of Companies (CGGC) has completed the entire breakthrough of the top heading of the Diversion Tunnel 1 of the Mohmand Dam and Hydropower Project (MDHP) in Khyber Pakhtunkhwa (KP).
The total length of the Diversion tunnel No.1 is 1681.14 m. The CGGC team, while terming the completion of diversion tunnel one as a “big achievement”, held a short ceremony at the tunnel site on Saturday. The CGGC workers were carrying a banner with the inscription “celebration for the entire break-through of the top heading in DT-1”.
MDHP consists of two diversion tunnels namely T1 and T2. The accumulated length of both the tunnels is more than three kilometers. The excavation has been executed in three layers including heading, benching and inverting due to the 15 meters large diameters of the tunnel.
Earlier this month, the Project Director of MDHP in an appreciation letter had commended the “tremendous project management skills” that despite the corona pandemic they executed the construction uninterrupted.
CGGC and DESCON are executing the 800MW MDHP in a joint venture. MDHP, which is constructed on the River Swat, is the fifth highest concrete-face-rock-fill Dam (CFRD) in the world. The first unit of the project is planned to be commissioned in December 2025.
