Description

The Jiashan Bridge project is located in the Eastern New District of Mingguang City, Anhui Province. It is a rare tower-beam-pier-consolidated system of cable-stayed bridges across high speeds. Route length of 1.22 kilometers, the bridge length of 715.9 meters, of which the main span of 270 meters, was 43 ° diagonal across the Ningluo high-speed. The main girder is 36meters wideand has 17 blocks on one side and 34 blocks in total. There are ladder bridges set up on both sides, and the ladder bridges are 4meters wide and constructed by underslung form travelers. The main tower adopts the herringbone bridge tower, which is 107.8 meters high, using a single tower double cable plane tower beam pier cementation system structure. The total project cost is 225.5 million yuan.

Jiashan Cable Stayed Bridge

Since the project entered the site, it has faced technical issues such as constructing variable-section herringbone tower columns, laying steel anchor beams and diagonal cables in the tower, and constructing high-speed form travelers across the large-section front fulcrum. 

Despite difficulties and hardships, Boyoun and all the staff of the project, undaunted by difficulties and hardships, gave their full effort to the project's enterprise style of being capable of suffering and fighting, constantly innovating the application of new technologies, such as the variable-section herringbone tower columns, the technology of the all-in-one machine for tower construction, the accurate positioning technology of steel anchor beams and cable ties of the main tower, the new type of crown structure of main tower and its sub-section installation program, the form traveler suspension casting of the front support point of the big section, and the construction of the tower. The innovative technologies such as front pivot forming traveler casting technology, high altitude tensioning anti-falling blocking box device, sinkhole "center island" sinking construction, and others have overcome a series of problems and fully guaranteed the smooth progress of the project.

With high-quality products and attentive after-sales service, the underslung form traveler provided by Boyoun were highly appreciated and praised by the project team!
