structure
The total length of the bridge is1453m, which is divided into two parts: the approach bridge and the main bridge.
The main bridge has sixteen holes and fifteen piers.
The upper part of the highway bridge is 6. 1 m wide, and the sidewalks on both sides are 1.5 m wide.
Less than three months after the bridge was built, the Japanese army set foot on the North Shore Bridge, and the * * * army ordered it to be blown up. It was not until after the victory of the Anti-Japanese War that it resumed traffic.
Qiantang River Bridge (1 1 Zhang) Time
The host of the design and construction of Qiantang River Bridge is Dr. Mao Yisheng, a contemporary bridge expert.
In order to complete the important task of building the bridge, Mao Yisheng resolutely resigned from the chair of Beiyang University and came to Hangzhou alone.
The bridge construction scheme he formulated was not only feasible, but also reduced the investment by about 2 million yuan compared with the scheme proposed by American bridge expert Walter, and was finally adopted by the authorities.
1934165438+1October 1 1, Qiantang river bridge started construction.
Mao Yisheng, 39, was appointed as the chief designer and chief engineer of Qiantang River Bridge.
At that time, the Japanese militaristic invaders had trampled on the northeast of China and targeted North China and even China in an attempt to subjugate the country.
Although Mao Yisheng was not a politician, he loved his motherland, and his worries about the current situation kept him sober.
The completion of Qiantang River Bridge not only greatly facilitates the traffic between the north and south of Qiantang River, but also forms a magnificent landscape along the south line of West Lake Scenic Area with Pagoda of Six Harmonies.

important event
Bombing the bridge twice
In order to prevent the Japanese from bombing the bridge 1937, the Lugouqiao Incident broke out.
Mao Yisheng had a premonition that he didn't even want to face up to it, and made an important decision to wake the world up-leaving a long Pagoda of Six Harmonies and the bombed Qiantang River Bridge on Pier 2 south of the bridge.
A square hole.
Mao Yisheng didn't explain to anyone why the original design hadn't changed much.
In August 1937 and 13, the Sino-Japanese War finally broke out, and the whole September and June 10 was extremely intense.
War and smoke filled Hangzhou, and the construction of Qiantang River Bridge entered the most tense stage.
On September 26th, the single-track railway bridge under Qiantang River Bridge was opened to traffic for the first time.
Mao Yisheng hoped that Shanghai could stop the Japanese attack. However, the three-month battle between Shanghai and Song ended in the fall of Shanghai, and Hangzhou was in danger.
Exhausted Mao Yisheng has clearly felt that he is unable to grasp the fate of the bridge.
165438+1October16 Mao Yisheng received an order from Nanjing to blow up the Qiantang River Bridge if Hangzhou is not guaranteed.
The rectangular hole left by Mao Yisheng at South Pier 2 is actually to prevent this moment from coming.
That night, Mao Yisheng marked all the fatal points of Qiantang River Bridge with the rigorous and accurate attitude of a bridge engineer.
Throughout the night, more than 100 wires were connected from all the explosion points to a house on the south bank.
With the same pain as strangling his own baby, Mao Yisheng accompanied the bridge that he had worked so hard to build until he saw the last lead connected with his eyes.
This is the most unforgettable, uncomfortable and painful day in Mao Yisheng's life. In the memories of his family afterwards, that kind of pain and helplessness really made him want to cry.
165438+1October 17 is the first day that the bridge that Mao Yisheng longed for but dared not expect was fully opened to traffic. When the first car crossed the bridge, hundreds of thousands of people on both sides of the strait applauded hard and the applause lasted for a long time.
Mao Yisheng later recalled: "All the hundreds of thousands of people who crossed the bridge that day, and those who crossed the bridge every day after that, everyone had to walk on explosives, and explosives flashed on the train.
On the first day of opening to traffic, there were explosives in the bridge, which was unprecedented in the history of bridges at all times and all over the world! 1 93712/23pm1,Mao Yisheng finally got the order: blow up the bridge.
At 5 o'clock in the afternoon, the vanguard of the Japanese army was faintly visible, the crowd was forcibly blocked, and all the fuses were lit.
With a loud noise, the banks of Qiantang River Bridge
Nine piers of Qiantang River Bridge were destroyed, and five steel beams broke and fell into the river.
The Qiantang River Bridge, with a total length of 1.453 meters, lasted for 925 days and nights, and cost 1.6 million US dollars. Finally, on the 89th day of its opening to traffic, it was paralyzed in the bonfire of Japanese aggression.
Japanese soldier You Yonghe photographed the bombed Qiantang River Bridge in smoke.
Decades later, Mr. You Yong and Mr. Fu came to Beijing, and with remorse for the war, he personally handed this photo he took to Mao Yisheng.
On the night when the bridge was bombed, Mr. Mao Yisheng stared at the ruins of the bridge he bombed through the boundless twilight, and looked at the increasingly bright flames on the north shore. Mao Yisheng wrote eight words on his desk with indignation: "If the Anti-Japanese War is won, the bridge will be restored".
His wish was not realized until 1946.
After the victory of the Anti-Japanese War, the Qiantang River Bridge was restored and became one of the key projects on the Zhejiang-Jiangxi line.
* * * The authorities tried to blow up the Qiantang River Bridge. 1949 On the eve of the liberation of Hangzhou in May, the authorities attempted to blow up the Qiantang River Bridge and prevent * * * from going south.
With the efforts of Hangzhou underground party and railway workers, the amount of explosives was greatly reduced in secret, and the fuse of key parts was cut off.
In the end, when the engineers bombed the bridge, only a section of track near the approach bridge on the south side of the bridge was damaged, and a hole was blown out on the bridge deck, but the main body of the bridge was not damaged too much.
At this time, the 63rd Division of the 2nd1Army of * * * has approached the bridge, and the engineers of * * * can't carry out further damage, and the bridge is finally returned to the people in a relatively complete way.
"A bridge that can't blow up if explosives are not put right" More than 30 maintenance workers in Qiantang River Bridge Workshop of Hangzhou Works Section of Shanghai Railway Bureau are responsible for the maintenance of the bridge.
He Guangming, director of the workshop who has been with the bridge every day for 20 years, said that the current maintenance is mainly aimed at railway sleepers, and the structure of the bridge has been well maintained. /kloc-it took 0/5-20 years to repaint the steel beam-that is, it was painted with a layer of paint.
The bridge has not been technically overhauled so far, and the maintenance in 2000 was the biggest, just replacing the bridge deck of the highway bridge.
"I said one thing, you can know how strong the bridge is.
This is a bridge that can't blow up unless the explosives are put in the right place.
Piers 5 and 6 of the bridge were bombed at 1937, 1944 and 1945, but they can still be used normally.
"Zhong Guangming said.
1937 65438+On February 23rd, Mao Yisheng received a secret order to blow up the Qiantang River Bridge, leaving only the remaining piers.
After the victory of the Anti-Japanese War,1May, 948, under the personal auspices of Mao Yisheng, the Qiantang River Bridge was successfully repaired again, fulfilling his oath that "the war will be won and the bridge will be restored".
