Last box girder completed for Weifang-Suqian high-speed rail section in Tancheng

The Tancheng girder yard of Section 10 of the Weifang-Suqian high-speed railway completed its 939th and final prefabricated box girder on Nov 5, clearing the way for bridge deck work on the Linyi stretch of the line.

The yard, built by China Railway Shanghai Engineering Bureau Group, produced 873 girders of 32 meters and 66 of 24 meters, all double-track simply supported box girders. Section 10 covers 40.822 kilometers of main line.

Prefabrication, rather than casting on site, is standard practice on China's high-speed rail projects because it allows girders to be produced under controlled conditions and installed in a single lifting operation, reducing disruption to roads and farmland beneath the alignment.

The yard reported what its parent company described as "six firsts" among the sections of the project — achievements in areas including early site preparation, first girder production and first girder installation. It received five commendation letters from the Linyi project headquarters and one from the Jinan-Zhengzhou project headquarters.

The yard's team won the Shandong "Lu'an Cup" safety competition and was named a "Pioneer Worker Team" by the Linyi Federation of Trade Unions, while its youth league branch was cited by China Railway and by the Shanghai bureau as a "May Fourth Red Flag Youth League Branch".

The Weifang-Suqian high-speed railway forms part of the auxiliary corridor to the Beijing-Shanghai high-speed railway, intended to relieve capacity pressure on the main line by offering an alternative route through Shandong and northern Jiangsu.
