Heavy Commuter Rail from Zhengzhou Airport to Xuchang, Henan, China
The new 35km commuter rail from the Zhengzhou Airport to Xuchang is designed as a precast segmental bridge using the short-line match casting method. The 25m / 30m long single bridge spans consist of 10 / 12 precast segments. There are two type of segment length with 2.45m and 2.50m, with a weight of up to 50tons. The Xuchang project is the first heavy rail project in China using the short-line precast segmental bridge technology and is designed by China Railway Siyuan Survey and Design Group Co., LTD (CRCC). SECI / SETI are responsible for the geometry control, quality control and precasting technology consulting support for the entire 35km long project. We are also responsible for the global, local and erection coordinates for the precast segments, including the fabrication and erection camber.
