Engineering work examiners have OKed the appraisal work and accepted a cast-in-situ simple-supported box girder, with a span of 50 meters as a movable formwork, which is prefabricated by China Railway No.4 Engineering Group Co., Ltd (CREC4) for the high-speed railway linking Xiongan New Area in North China’s Hebei Province with Shangqiu in Central China’s Henan Province.
CREC4 builders, working for the No 11 bid for the exterior railway lines for the 552-kilometer HSR, completed the acceptance work on August 10, 2023, representing the first item for engineering evaluation in building the HSR and ushering in a new milestone for casting the cast-in-place simple-supported box girders in the future.
The appraisal and acceptance work was organized by China Xiongan Group. Xiongan New Area, which was established on April 1, 2017 by the central authorities, spans the three counties of Xiongxian, Rongcheng and Anxin in Hebei, and is aimed to relieve Beijing of functions nonessential to its role as the national capital in a bid seek a new development model for densely populated areas. The new area, dubbed “a strategy crucial for a millennium to come,” will help advance the coordinated development of Beijing-Tianjin-Hebei region.
The cast-on-site simple-supported box girder, with a span of 50.7 meters between the No 799 pier and the No 800 pier, was examined by experts over its standardized management, resource allocation, quality records, and physical quality of the movable formwork. The examiners conducted on-site spot checks on its physical quality, and OKed the acceptance work.
The Xiongan-Shangqiu section, part of the Beijing-Xiongan-Shangqiu HSR running for 639 kilometers with 18 railway stations, will extend for 552 km with 16 stations allowing trains to run at a designed speed of 350 km per hour. CREC4’s job, or the No 11 bid for the new HSR, runs for 17.32 km, starting from Taiqian county in Henan’s Puyang and ending at Jining city of Shandong.
It has been learned that the Xiongan-Shangqiu section of Beijing-Xiongan-Shangqiu HSR will also be an important part of the Beijing-Hong Kong-Taiwan HSR included in the country’s “eight verticals and eight horizontals” HSR network. Upon operation, it will connect with the Beijing-Xiongan section, and some other high-speed railways in the country.
