Jingbin High Speed Railway

The Jingbin high-speed railway breaks through with the core of “air rail intermodal hub” and “complex geological shield technology”. The shield section is 7.72 kilometers long and needs to pass through airport taxiways, Jishan Expressway, seismic liquefaction layers (11-20 meters underground), and double layered pressurized water layers. The settlement control accuracy requires millimeter level precision. Not only does it reshape the “half-hour economic circle” of Beijing Tianjin, but it also sets a technological benchmark for the Beijing Tianjin Hebei rail transit network with innovations such as CRTSIII track and fully prefabricated assembly.
