Description

The Lanzhou-Chongqing Railway Overpass Bridge in the Guangyuan-Mianyang section of the Beijing-Kunming Expressway is located in Guangyuan City, Sichuan Province. It features a continuous steel structure of 70+130+70 meters, with a double width and cantilever form traveler suspension casting construction.

The main bridge box girder is a three-dimensional prestressed structure in the longitudinal, vertical and transverse directions, with a single box and single cell section. The top plate of the box girder is 16.85 meters wide and the bottom plate is 8.85 meters wide. The top plate of the box girder is set to a 2.0% one-way cross slope. The cantilever pouring section has a maximum control weight of 211 tons.

The project adopts a leasing model. The project site is only 200 kilometers away from the Sichuan base. The materials can be delivered to the project site within 24 hours. This not only reduces transportation costs but also saves time, ensuring the project's construction period.

Boyoun has established three bases in Guizhou, Sichuan, and Jiangxi to provide coverage in the southern region of China for the southern market. The southern region has a coverage radius of 600 kilometers. Each base has complete product support and sufficient materials, allowing nearby projects to be quickly assembled, saving customers a lot of procurement and time costs.

Boyoun focuses on customer experience, providing professional, proactive, and efficient services to reduce construction management costs and ensure construction safety. We strive for high-level service and continuous self-improvement to continually enhance customer satisfaction.

Currently, the mid-span of the Lanzhou-Chongqing Railway Overpass Bridge is nearing closure. Boyoun will continue to work closely with the project construction team to open the full-line bridge as soon as possible and contribute to Guangyuan's regional transportation and economic development.
