President Joko Widodo Inaugurates the Drilling of MRT Connecting HI-Lebak Bulus
President Joko Widodo inaugurated the operation of tunnel boring machine (TBM) of Jakartas Mass Rapid Transit (MRT) project, at Patung Pemuda (Statue of Youth), Senayan Roundabout, Jakarta, on Monday (21/9) morning.
The machine that drills approximately 8 metres per day will operate 24 hours a day, starting from September to December 2016.
President Joko Widodo gave a name Antareja to the first drilling machine referring to a character of underground wayang.
According to the plan, the MRT project will use four drilling machines. Two machines will be used to drill a tunnel from Senayan, specifically under the statue of Api Nan Tak Kunjung Padam/eternal flames (Senayan Statue), South Jakarta, to Setiabudi, Central Jakarta. The other machine is still at assembly process.
The TBM machines use the first earth press balance technology in Indonesia. Constructed by Japanese company, the machines will be operated by Shimizu, Obayashi, Wijaya Karya and Construction Service.
The underground drilling is guaranteed to be safe, not causing vibration or landslide. People do not have to worry about the rainfall because the underground station is constructed with layered wall.
