Shihe Bridge

Shihe Bridge

Shihe bridge, located in the west section of Hepeng at the junction of Luoshan and Xinyang, spans the East and west sides of Shihe River. It has been standing for nearly 80 years and abandoned for 30 years without collapse. It is called "living fossil of the bridge". On December 6, 2012, netizen microblog revealed that the bridge was supported by wood, which aroused social concern.

Brief introduction to the bridge

On December 6, 2012, netizen "@ free man reborn" tweeted that there is a reinforced concrete highway bridge in Luoshan County, Henan Province, which is actually supported by wood. Pictures attached to the microblog show that the bridge has many piers, but at least two of them are supported by many wooden piles.

The microblog was repeatedly forwarded, and many netizens accused Jianqiao of cutting corners in comments.

Luo, Vice Minister of the Propaganda Department of the Luoshan county Party committee, said at 8:45 p.m. on the 6th that it was preliminarily confirmed that the bridge was Shihe bridge, the old 312 National Highway in the county, built by the Japanese during the Anti Japanese war. "This should be the old construction technology, can not be completely measured by modern construction technology."

In addition, the Highway Department of Xinyang city also carried out investigation and verification, confirming that the bridge was built in 1938 and abandoned for 33 years after the national highway 312 was changed in 1979. comprehensive

County records: "bridge strong" by the national government construction, has been 78 years

Luoshan county annals, published in 1987. The book records the information of the bridge in detail, which is different from the information disclosed by the Propaganda Department of Luoshan county Party Committee on the night of December 6——

Shihe bridge, located in the west section of Hepeng at the junction of Luoshan and Xinyang, crosses the East and west sides of Shihe River and is 21 kilometers away from Luoshan county. It is one of the main large bridges of Xinye highway. In 1923, Fang Shaoyao, director of Luoshan public funds Bureau, built a simple wooden bridge 244 meters upstream of the existing bridge to allow small cars. In 1925, it was destroyed by floods. In 1932, the KMT government built a 47 hole low water level wooden bridge with a length of 64.8 Zhang and a width of 1.05 Zhang, which could pass through ordinary cars. Soon, it was destroyed by water. In 1934, the KMT government built a permanent bridge on the site of Muqiao. A total of 29 holes, each with a span of 12 meters, are reinforced concrete T-shaped beams, with a total length of 360 meters and a width of 5 meters, and railings on both sides. At that time, it was one of the largest bridges in Henan Province. In 1938, the Japanese army invaded Southern Henan. When the Kuomintang troops retreated, they blew up the two holes at the east end of the bridge. After the victory of the Anti Japanese War, it was repaired and opened to traffic. But the bridge deck is narrow and the traffic is not smooth. In 1978, the state built a new bridge 244 meters downstream of the old bridge (now in use on national highway 312).

Multiple proposals

Hot discussion among netizens

This is a "living fossil of the bridge", which should be repaired and protected as soon as possible. Wang Yaoping, author of the Treaty of Luoshan, tells the history of the Shihe bridge in Luoshan.

"The wooden piles under the piers of Shihe bridge are hard to pick by hand. The wood is very hard. Listen to the old man at the end of the bridge, it's red pine from Northeast China." Wang Yaoping said, "during the battle in Wuhan in 1938, Hu zongnan blew up the Shihe bridge in liangkong in order to prevent the Japanese from attacking. Because the bridge was so strong, hundreds of people were killed and injured just by blowing up the bridge." Wang Yaoping said that according to various materials, it should be misinformation that the Shihe bridge was built by the Japanese, because from the end of the Luoshan battle in October 1938 to the end of the Wuhan battle in December, the Japanese army had no time to build the Shihe bridge.

Wang Yaoping said that although the bridge may not be called a cultural relic, it should be a "living fossil" of the bridge construction in the 1930s and 1940s. It has high specimen value and should be well preserved.

Many netizens echoed this suggestion on the Internet. A netizen said: "this bridge can stand for nearly 80 years, abandoned for 30 years without falling down, and still stands tall, fully qualified to become a strong bridge. There are not many living old bridges in China. Although the bridge is not 100 years old, it is after all the building of the Republic of China in the 1930s. It's better to keep it, maintain it, and make a living textbook. "

As for the question of "how do you think the government should deal with Xinyang's" strong bridge ", an online survey launched by dahe.com also shows that 88.89% of netizens hold" protect it ".

Decrease of river sand and exposure of wooden piles

In fact, the "strong bridge" is similar in length to the 312 National Highway Bridge in the north and the Ningxi railway bridge in the south, with spans of about 800 meters. The Shihe River under the three bridges basically flows north-south, while the bridge basically crosses the riverbed of Shihe River from east to west.

In the dry season, with the river closure being carried out 300 meters upstream, there is basically a dry beach within 200 meters from "qiaoqiang" to Ningxi railway road bridge (which has been built and used). The eastern part of Shihe River bed is obviously higher than the western part. The lowest part of the whole river bed is between the three piers in the western part. The thin and shallow river flows under two piers, and the wooden piles supporting the bridge are exposed.

At the scene of Shihe bridge, with the help of the strong light searchlight carried by Li Jun, deputy director of Luoshan County Highway Bureau, the reporter saw that the wooden piles supporting each pier were between 23 and 27. According to the situation, at the beginning of piling, the wooden piles under each pier should be divided into 9 rows, 3 piles in each row, neatly and evenly distributed. The reporter can still feel the fineness and firmness of the wood when touching the stake.

After careful inspection of the site, the highway technicians believed that these wooden piles should be wedged into the river beach, drilled through the sand layer, and firmly penetrated into the river bottom to form cement pier pile foundation; then, the construction personnel nailed a circle of dense wooden piles around the pile foundation to protect the pile foundation, and poured reinforced cement pier. The pier was stably located on the pile foundation that penetrated into the bottom of the beach to form a stable pile foundation Set a solid pier. As the river has been scouring for many years, especially in the past 20 years, a large amount of river sand has been dredged, resulting in less and less river sand under the piers, and finally exposed the wooden piles.

"The eastern part of the river bed is close to Luoshan County, where little sand is dug, and the wooden piles under the piers are not exposed, while a large number of wooden piles are retained to protect the piers; the western part of the river bed is Wulidian town in Pingqiao District, where sand is dug frequently and the river sand is lost much, so the wooden piles are exposed seriously." Zhang Tian, a villager, said.

Official response

There are hidden dangers in Shihe bridge, and Luoshan County advocates joint demolition

Wang Yaoping also admitted that although there are no obvious main body deformation, cracks and other problems of Shihe bridge at present, villagers on both sides still have some potential safety hazards due to the lack of guardrails in the past, including the safety of exposed wooden piles of piers, which needs the attention of local villagers and government departments.

On December 7, the person in charge of the transportation department of Luoshan County said: "we have long been considering eliminating hidden dangers and demolishing the bridge. Just a bridge across the two counties, has not taken action

"Within a distance of less than 1000 meters, this section of river bed is densely covered with a highway bridge and a railway bridge in use. Another railway bridge is also under intensive construction and will be completed soon. The abandoned bridge is meaningless and has many hidden dangers. We suggest that the municipal highway bureau come forward, coordinate and organize the two counties and districts, and jointly demolish them. " Luo Shan said.
