steel structure bridge

In the past ten years, steel structure bridges have become the main structural form of large bridges because of their good quality.

The steel structure is made by customization. According to the actual geological environment of the bridge, the exclusive bridge steel box is customized, and the quality and construction period can be guaranteed. Steel structure bridges have good wind resistance and stability, and are light in weight, which will be much more convenient in construction projects.

Of course, steel bridges also have shortcomings. In terms of bridge deck paving, the temperature difference of steel bridge decks is large, the requirements for waterproofing and rust prevention and interlayer bonding are high, the stress of bridge decks is very complex, and the local strain is large, all of which determine The use conditions of steel bridge deck pavement are far harsher than that of ordinary asphalt bridge decks.

At the same time, the service life of the steel bridge deck is much lower than that of the ordinary bridge deck. Therefore, the paving scheme of the steel bridge deck adopts a special method to improve the service life of the bridge deck.
