Once, the first railway in China was built by the British,Nowadays, our country has become the "infrastructure demon" praised by everyone in Western countries.

Over the past century of ups and downs, Chinese people have not only stood up, but also obtained business cards that they can handle. Among them, the most representative isHumen Bridge .

During the peak period of traffic flow,600Humen Bridge .

But yesterday's glory has disappeared,Humen Bridge .

A bridge dedicated to the return of Hong Kong

1997.

Since 1992, more than 1600 engineering and technical personnel, cadres, and bridge construction workers have been rooted in Humen,They spent four and a half years,199769.

At the initial design stage,1212.

Such a high traffic volume inevitably requires higher load-bearing capacity for the bridge body, and at the beginning of construction, we wanted to seek the help of foreign engineers,.

The reason why the maintenance department was established so quickly is that although the bridge is open to traffic, there are still some remaining problems,.

On the surface of the steel structure, we can repaint and undergo anti-corrosion treatment, but what should we do inside the steel structure?

Without foreign engineers providing advanced technology,Humen Bridge .

Combined with the previous Thai Bridge on the Gulf of Thailand in Scotland, an accident occurred in a strong wind in 1979,Causing 75 deaths.

The advantages of suspension bridges are obvious, such as the maximum crossing capacity, relatively economical engineering cost, and high traffic space on the bridge deck,.
