📋 Tender Overview
Recently a successful closure was made for the main spans continuous beams of Hangzhou-Quzhou High-speed Railway Extra-long Bridge over-crossing Jinhua-Qiandaohu Railway invested and generally-contracted by China Railway SIYUAN Survey and Design Group Co. Ltd. With the closure of continuous beams of the last bridge among the 7 extra-long bridges in Lot 2 of the civil works of the Hangzhou-Quzhou High-speed Railway it marks the breakthrough of the project construction laying a solid foundation for the follow-up beam construction and ballastless track construction.With a total length of 685.99m the successfully closed bridge over-crossing Jinhua-Qiandaohu Railway is located in Jiande City Hangzhou connecting Xitangwu Tunnel and Huangjianshan Tunnel. This bridge is the only one with continuous beams over-crossing railways highways and rivers successively over the whole line. It over-crosses Jinhua-Qiandaohu Railway which is an existing busy freight line as well as G330 National Highway and Nanpu Stream giving rise to great construction difficulty and high safety risks.During the construction process the project department of China Railway 11th Bureau focuses on three aspects namely existing line safety protection G330 national road traffic safety and the water resource protection of Nanpu Stream with a special construction plan prepared. In order to ensure the traffic safety below and the construction safety on the bridge the project department adopts the hanging basket for an overall protection in the main construction of the bridge to prevent small objects concrete debris and other debris from falling during the construction of continuous beam construction which affects the traffic running. During the construction of the main body of the continuous beam and the bridge deck system the contractor carries out near-the-edge protection of the flange board and untwines the traffic under the construction area to ensure the traffic safety and therefore ensure the smooth closure of the continuous beams.As one of the ten top typical major passage construction projects in Zhejiang Province Hangzhou-Quzhou High-speed Railway is the first high-speed railway operating in the mode of PPPEPC in China. The social investor led by China Railway SIYUAN Survey and Design Group Co. Ltd. dominates project investment and construction in EPC mode. China Railway Shanghai Group Co. Ltd. is entrusted as the construction agent. After completion it will achieve the multi-point and multi-passage connection between Quzhou and Hangzhou which is of great significance to relieve the transportation pressure of the Shanghai-Kunming Railway support the development of Hangzhouxi Railway Station as a hub promote the urban integration of Hangzhou and Quzhou and help the high-quality development and build a demonstration zone for common prosperity of western Zhejiang.
