A bridge flying over the canyon,

Graben becomes a thoroughfare.

In the vast river of human civilization, bridges are not only physical channels connecting the two sides, but also the intersection of history and the future.

Over the years, Carpoly has participated in many bridge construction anti-corrosion coating projects, including Guizhou Qingshuihe Bridge, which has witnessed the historical changes of Guizhou and bears the future development of Guizhou.

Carpoly provides anti-corrosion coating scheme for concrete piers of Qingshuihe Bridge

"The land is not three feet flat" - this is probably the most suitable description of Guizhou. Karst landform accounts for more than 60% of the whole province. There are many ravines between the mountains. Two points are not far away from each other on the map. The middle distance may need to cross mountains and rivers up and down.

In order to shorten the traffic distance and improve the transportation efficiency, Guizhou has set up a number of high-speed bridges in the vertical middle of high mountains and canyons. Qingshuihe Bridge is one of the shining pearls.

The bridge has a total length of 2171m, a main span of 1130m and a height of 406m. When completed, it was the second highest bridge in the world and one of the suspension bridges of the world's largest span plate truss composite stiffening girder bridge.

The Qingshui River Bridge overlooks the Baling River Canyon. The winding road below is in sharp contrast to the straight and swift bridge deck.

After the Qingshuihe Bridge was completed and opened to traffic, the driving distance from Guiyang to Weng'an was shortened to one hour, ending the history of inconvenient local transportation and opening a more convenient and better future. When a highway network connects villages deep in the mountains with the outside world, at least everyone has the possibility to walk out of the mountains.

And if we turn our attention to other local

▲ Changchun three horizontal and five vertical viaducts

▲ Shanghai Yangpu Bridge

▲ Xia door Second East Passage

▲ Foshan Fengxiang Bridge

The urban agglomerations on both banks, once cut off by mountains, canyons and vast rivers, are closely connected in the "threads" of traffic arteries. These infrastructure integration and networking, represented by the bridge, have always been the basic driving force for regional economic development. They are not only a link connecting physical space, but also a bridge connecting history and future, witnessing the past of mankind and looking forward to the future of mankind.

In history, with professional ability

Create the future

The completion of super bridges has witnessed the history and technological development of bridge building in China, from iron cables to steel bars to steel cables, from ordinary ones paint reach epoxy Zinc rich, inorganic zinc rich Acrylic acid polyurethane Wait a series of weights Anticorrosive coating The continuous development of materials has achieved the iteration of bridges. And Carpoly is also lucky to be a witness and participant of history, to participate in it with professional ability, and to jointly build these bridges that have an important impact on the future.

For steel structure bridges and concrete bridges, Carpoly Industries coating Various targeted anti-corrosion protection supporting products are provided to provide professional and efficient coating schemes for bridges in different environments.

If the bridge is not protected by anti-corrosion coating, it may be difficult to resist the wind, sun and torrent erosion. But when the Carpoly coating is covered on the surface, they have better protection, can withstand the traffic load and external environmental impact, while maintaining good appearance and performance, greatly extending their service life, so that the bridge can stand in the canyon and sea for a long time.

With the rapid development of the times, these magnificent and tall construction projects are constantly changing our lives and leading us to a better future. Meanwhile, Carpoly also uses paint to protect and decorate these buildings, making them one after another monuments in the long history, so that they can accompany us for a longer time.
