The country will increase its support for prefabricated buildings and encourage other construction industries to adopt the prefabricated building model. In recent days, Guangxi has completed the construction of the lower structure and prefabricated beam erection of China's first prefabricated bridge.

The prefabricated construction process of bridges is like building blocks, using large cranes and other lifting tools to transport pre fabricated molds to the construction site and carry out assembly work. As this construction mode is still in the initial stage of bridge construction, the difficulty of the operation is relatively high, and reference cases are small. In order to quickly and safely complete the assembly work of bridge components, the project construction team used multiple large tonnage screw jacks to adjust the height between each component, so that the error of each part is within 5 millimeters, thereby ensuring the stability of the bridge during use.

By using multiple jacks, the installation accuracy of the prefabricated bridge has been controlled within a range of 5 millimeters, improving the strict control and safety efficiency of the construction work of the prefabricated bridge.
