SYSTRA Shanghai has contributed to the creation of two sections of the Zhengwan
HSL, which crosses China from the southwest to the centre and continues the development of high speed rail in China.
Movements on the new Zhengwan line began on 1st December 2019 between the
capital of Henan Zhengzhou and the second largest city Hubei Xiangyang. This incudes two sections for which SYSTRA supervised the construction, as technical asssistant to the local contractor ZTCY, for a length of 192km, half the 389km commissioned for this first section.
The first section covers the crossing and outskirts of Xiangyang over 143km, including the two stations of Dongjin and Nanzhang. The second section involves the crossing and outskirts of XinYe over 49km, including the station of Dengzhou East. SYSTRA experts were mobilised for the civil engineering works supervision of these sections mixing 44km of tunnels, 102km of single and twin-track viaducts, as well as assignments for earthworks and the management of five box girder prefabrication sites.
The works started in September 2016 and finished in 2019 on the XinYe section, and in October 2019 for the Xiangyang section. On site, SYSTRA also ensured the quality control, the safety inspections, the audits and the independent certification of all the construction sites (bridges, embankments, tunnels, concrete slabs, maintenance zones and stations).
By 2022, the Zhengwan HSL will link Zhengzhou to Chongqing in the south of the country via Wanzhou. Its length will therefore double to 818km for a complete journey in less than 4 hours, thanks to a commercial speed of 350km/h. China is today the country with the longest HSL network and since 2002, SYSTRA has made a strong contribution to its expansion.
A pioneer among international engineering companies in the country, our Group has won around 20 contracts to support HSL in China, which had close to 30,000km in 2020 and should reach 38,000km by 2025.
