Beijing-Tangshan rail construction gears up for enhanced regional links

Construction of the Beijing-Tangshan Intercity Railway — an infrastructure project aiming to boost integration of the Beijing-Tianjin-Hebei cluster — has been making rapid advances, reflected by faster tunneling progress reports from participating State-owned builders.

During a recent media event, China Railway 14th Bureau Group Corp Ltd, a unit of China Railway Construction Corp, said its major tunnel boring machine Jingtong is inching closer to completing its mission — digging the Yunchaojian River Tunnel — which is currently 30 meters underground in Beijing's Tongzhou district.

Taking into account the geological and environmental conditions in the capital city, CR14G's shield machine design team customized the domestically produced super-large diameter Jingtong TBM.
