It serves as a municipality directly under the Central Government, a national central city, a megacity, the economic center of the Bohai Rim region, and one of the first batch of coastal open cities. It is also a national base for advanced manufacturing and R&D, the core area for international shipping in Northern China, a demonstration zone for financial innovation and operations, and a pioneering zone for reform and opening-up. Binhai New Area It is a municipal district of Tianjin, a sub-provincial-level district, a national-level new area, and a national comprehensive pilot zone for institutional reform—making it the first national comprehensive reform and innovation zone approved by the State Council.

According to reports: Tianjin Metro Line Z4, It is one of the lines included in the Tianjin Metro’s rail transit master plan, with an initial phase spanning 43.7 kilometers and comprising 23 stations—10 underground and 13 elevated. The Z4 Line is a highly ambitious rail transit project, with a planned total length of 100 kilometers. It is not only intended to serve the Binhai New Area but also the eastern part of the entire city of Tianjin, offering broad prospects for future development.

During the construction of Tianjin Metro Line Z4, Dongfeng Shijing Template Group Co., Ltd. Designed and manufactured “Double-U+Box-Type” Segment Assembly It has played an extremely important role. According to available information, this formwork-beam structure is highly complex, featuring high precision, superior strength, a high degree of automation, light weight, and a sleek, streamlined appearance—truly standing out as a unique member of the “segmental assembly” product family. As noted by a responsible representative from China State Construction Third Engineering Bureau Co., Ltd., the distinctive design concept behind this segmental assembly approach, coupled with its innovative precast component demolding process, is also rare in the history of rail transit construction.

Recently, “Double-U+Box” Short-Span Composite Variable-Section Prefabricated Cantilever-Assembled Segmental Girder , the Z4 project in Tianjin was successfully concreted and smoothly demolded, with each segment measuring 3 meters in length and weighing 102 tons, thereby not only filling a gap in China State Construction Third Engineering Bureau A technological gap in the relevant field, while also Dongfeng Shijing Template Group Co., Ltd. Another powerful demonstration of a major innovative achievement.

Since taking on the order, technical personnel and frontline workers at Dongfeng Shijing Formwork Group Co., Ltd. have spent four months meticulously designing and manufacturing the project, successfully delivering to the client on time four sets of segmental formwork totaling over 500 tons in weight, along with all associated accessories, while also conducting thorough technical briefings and providing on-site installation guidance. This successful concrete placement and smooth demolding have been highly praised by China State Construction Third Engineering Bureau High praise from the relevant leaders, along with the hope that cooperation will continue to be strengthened to jointly strive for Tianjin Line Z4 Strive for early completion and opening to traffic.
