He overcame more than 80 difficulties and laid the foundation for China's modern bridges

bridge

It is an important symbol of a country's modernization

Hong Kong-Zhuhai-Macao Bridge, Hangzhou Bay Bridge, Wuhan Yangtze River Bridge

When we return to the starting point of China's modern bridge

There is a name we will never forget.

He is Mao Yisheng

1935

Mao Yisheng presided over the construction of the Qiantang River Bridge

However, the Qiantang River is turbulent and the water is high.

Construction on water is very difficult

Mao Yisheng recorded and observed

Taking advantage of the unique hydrological laws of the Qiantang River

The first to create technologies such as "caisson method", "water jet method" and "floating method"

More than 80 major and minor problems in the construction were solved one by one

After two and a half years of hard construction

The Qiantang River Bridge was finally opened to traffic on September 26, 1937.

This is a great feat of Chinese people to independently design and build a modern bridge.

But no one would have thought

Just 89 days later

This bridge is filled with all the hard work of Mao Yisheng

Because of the need of the war

He destroyed it himself

It was not until 1954 that Mao Yisheng presided over

Fully restored and opened to traffic

Building a bridge is patriotism, destroying a bridge is patriotism, and restoring a bridge is also patriotism

In Mao Yisheng's heart

Building bridges for the country is the duty of scientists

It is also a place where we should serve our country

In the history of Beijing Association for Science and Technology

Several famous scientists have served as chairmen

Bridge expert Mao Yisheng is one of them.

Today let us

A special topic on the achievements of popular science in the past five years of Beijing Association for Science and Technology

Tribute to bridge scientist Mao Yisheng
