Ganjiang Bridge connects the railway "cecum"

Yangtze Island, located downstream of Bayi Bridge, has a highway and railway bridge running through the north and south. Old Nanchang, who is familiar with history, knows that this is a bridge connecting Nanxun Line and Zhejiang-Jiangxi Line, and it is the second river-crossing bridge built in Nanchang after Bayi Bridge-Nanchang Ganjiang Bridge.

"Ganjiang Bridge connects Nanxun Line. It is precisely because of this bridge that this railway' cecum' can enter the urban area and connect with the whole country. " Talking about the history of Ganjiang Bridge, Liu Jianping of Nanchang Railway Bureau Archives said.

Nanxun Railway was completed in June 1907 and June 1, which is the second railway line in Jiangxi Province (the first line is Zhuping Railway completed in June 1899). Liu Jianping said that according to the initial planning of Nanxun Railway, it is divided into three feeder lines, one is Jiujiang to Nanchang, Ji 'an and Ganzhou to connect with Guangdong-Shanghai Railway; The three feeder lines are respectively connected with Zhejiang Nanchang to Shangrao, Fujian Nanchang via Fuzhou, and Zhuzhou Nanchang to Pingxiang, Hunan.

However, due to the limitation of national strength and the influence of war at that time, the repair of Nanxun Railway stopped. 1965438+In June 2006, the Jiujiang-Niuxing section of Nanxun Railway was completed and officially opened to traffic. However, at that time, because Niuxing at Nanchang Station was separated from downtown Nanchang by the Ganjiang River, passengers entering and leaving Nanchang had to cross the river to ferry, which was extremely inconvenient.

On September 1937, the Zhejiang-Jiangxi line was completed and opened to traffic. Because the Ganjiang River is separated by a river, Nanxun Line and Zhegan Line can only face each other across the river and cannot be connected. Especially Nanxun Line, the Yangtze River in the north and Ganjiang River in the south. Since its completion, it has been a separate line, which cannot be connected with the national railway and has become the "cecum" of a railway. Therefore, there is a folk proverb in Jiangxi, which is called "the son of Hedong and the daughter of Hexi, it is difficult to get married."

Jiangxi people look forward to building bridges for nearly half a century. With the establishment of new China, it is very necessary to connect the two lines. 1956 In May, the Ministry of Railways decided to build Nanchang Ganjiang Bridge.

advanced technology

The pipe string with a diameter of 5.8 meters is the largest in China.

1958, Jiangxi province formulated the railway network plan of 10, and planned to add railway lines of1722km, among which Ganjiang Bridge was impressively listed. In August of that year, the Ministry of Railways decided to design Nanchang Ganjiang Bridge according to the dual-purpose railway and highway bridge.

"According to the original design, Nanchang Ganjiang Bridge is divided into north and south bridges, with a total length of 126+08 meters. South bridge 1 1 hole, 66 1. 12m long; The North Bridge has a 14 hole and is 565.06 meters long. The connecting line of the Yangtze River North-South Bridge is about 1.6 km long. " Liu Jianping told reporters that the Ganjiang Bridge was officially started on September 30th, 1958, when three famous Wuhan Bridge Bureaus were built.

Liu Jianping said that as the "big brother" of domestic bridge construction at that time, the third branch of Wuhan Bridge Bureau adopted the most advanced large pipe pile structure technology at that time in the pier construction of Ganjiang Bridge in Nanchang, that is, each pier at the lower part of the bridge used reinforced concrete pipe piles with a diameter of 5.8 meters as the foundation, which was the largest pipe pile in China at that time, saving about 2.9 million yuan compared with the original planned 1.55-meter pipe pile foundation scheme.

A tragic accident

89 people were killed when they capsized and fell into the water.

"In fact, in order to build the Ganjiang Bridge, we also paid a very painful price." During the interview, Liu Jianping also told the reporter a sad tragedy:1March 6, 959, 100. When more than one bridge builder was carrying a tugboat to the center of the river for construction, a strong wind of magnitude 5 or 6 suddenly blew on the river. Because the tugboat was illegally overloaded, it caused a serious rollover accident, and all the people on board fell into the water. Despite the rescue efforts, due to the stormy weather, things were in a hurry, and 89 people were killed except some people who escaped from danger. This is the biggest tragic accident in the history of bridge construction in China.

"Most of the workers killed at that time were skilled technicians, which brought great difficulties to the normal construction of the project." Liu Jianping said that due to the lack of construction strength, the Ministry of Railways transferred more than 200 people from the Xiaoshan-Ningbo railway project to Nanchang to participate in the bridge construction.

Touching memories

Reward rice and encourage workers to pick earthwork.

From June 65438 to June 0959, the Ganjiang Bridge project lasted 8 and a half months, and 27 piers and abutments of the North-South Bridge were completed. At the same time, the railway lead project between the two ends of the bridge and the south-north bridge has also started. The total length of the main line is 14km, connecting Nanxun Railway and zhejiang-jiangxi railway.

In order to speed up the construction of Ganjiang Bridge, the Jiangxi provincial government mobilized more than 6,000 migrant workers from Ganzhou and Fuzhou to take the lead in earthwork construction. Liu Jianping told reporters that the connecting line between the south bridge and the north bridge of Ganjiang River is 1.4km long, which is located at Zhoutou of the Yangtze River in the middle of the river, with low terrain, which is the same as the embankment at the south end of the bridge, and needs to be backfilled with a lot of earthwork. However, because there are sandbars at both ends of the Ganjiang River and there is no soil filling, the source of backfill earthwork has become a big problem.

"The earthwork of the southern line needs to be excavated outside Liangjiadu Station, more than 40 kilometers away, and transported to the bridgehead of Ganjiang Bridge by railway to unload the fill. The earthwork on the northern line has to be pushed by trolleys in other places, which adds a lot of workload. " Liu Jianping said that the construction of Ganjiang Bridge coincided with three years of natural disasters, which was the most difficult period. At that time, food was in short supply. Many migrant workers left the construction site because they didn't have enough to eat, and the project was forced to stop.

Later, the Nanchang municipal government organized government officials to borrow soil from the construction site, and the effect was not obvious. Therefore, leaders of Jiangxi Provincial Party Committee Shao Shiping, Liu Junxiu and others decided to allocate more grain, and encouraged workers' enthusiasm by launching soil-borrowing competitions and rewarding rice, which achieved remarkable results and greatly improved the speed of subgrade filling.

Premier Zhou delivered steel for the bridge.

Just as the whole project was gritting its teeth and advancing step by step, a crisis came quietly.

"Because the country was in a difficult period at that time, the steel beams used to build the bridge could not be supplied, which led to a long interruption of construction." Liu Jianping said.

One day in June, 1960, when the workers were wandering around the construction site, they found a group of people standing by the bridge, including Premier Zhou Enlai, who often read in the newspaper.

In fact, Premier Zhou has been paying close attention to the construction of Ganjiang Bridge. When Nanchang Bayi Bridge was opened to traffic, Premier Zhou Enlai said that another Ganjiang Bridge would be built, and the Ministry of Railways would build Ganjiang Bridge into a bridge with trains in the middle and pedestrians and carriageways on both sides, thus conspiring for the future Hongdu Avenue. This time, Premier Zhou Enlai came to Nanchang to inspect the construction of Ganjiang Bridge which he cared about.

Liu Jianping told reporters that the Ganjiang Bridge was originally planned to be completed at 1960, but Premier Zhou only had eyes for the piers. He asked the staff why they stopped working. After learning that there was no steel, Premier Zhou said, "I will go back to solve the problem of steel, but I must take the train to cross the bridge next time I come to Nanchang."

Later, under the personal coordination of Premier Zhou, the steel beams urgently needed by the bridge were manufactured by Shanhaiguan Bridge Factory and delivered to the construction site one after another.

It took five years to build the "steel artery"

196 1 65438+February, Nanchang Ganjiang Bridge was completed, connected with the southern section of the lead, and began to pass through the engineering train. 1 962 April1day, Ganjiang Bridge was completed and temporary freight transportation began. 1962 In May, Nanchang Railway Bureau and Wuhan Bridge Engineering Bureau jointly conducted a preliminary inspection. 1.963 1.00 was officially accepted by Jiangxi provincial people's government and other relevant units, and the bridge was officially put into operation on 1.963 1.00.

"After more than five years of hard work, tens of thousands of builders starved and finally set up a steel artery on the Lancang River." Liu Jianping said that the completion of Ganjiang Bridge ended the embarrassing situation of Nanxun Line operating independently for nearly half a century, and laid a solid foundation for the Beijing-Kowloon Railway to be completed three years ahead of schedule in the 1990s.
