The Yuanjiang Railway Bridge has the longest span between the world’s tallest pier and two piers. It is part of the 925.5-kilometer Chinese section of the China-Laos Railway. After the builders completed the installation of 18, they were significantly promoted by 56 steel truss composites. The body forms a bridge.
This 832.2-meter-long railway bridge spans the Lancang River, with four piers in the middle and two platforms at the two ends. It is considered to be a arduous project on the China-Laos railway and a major project of the “Belt and Road”.
Zhou Jihong, project manager of China Railway Fourth Engineering Group Co., Ltd. (CREC4) said: “We are now heading to the highest terminal and hope to arrive before the end of October this year.”
Zhou said that the main span of the Yuanjiang Railway Bridge is 249 meters long, and its No. 3 high pier is 154 meters high and the upper level is 54 stories high.
Chen Changguo, deputy secretary of the CREC4 Fifth Division Committee, said that the highest terminal foundation is 78 meters underground and built for 22 months. Even without trains, it can withstand more than 150,000 tons. Participated in this project.
The double-track bridge spanning the V-shaped Red River Canyon in southwestern China is one of the 134 bridges built on China’s 508.5-kilometer railway, connecting Yuxi City in Yunnan and Vientiane in Laos. It will be fully operational in December 2021.
According to Chen, the construction of the Chinese section, also known as the Yuxi-Mohan Railway, began to invest 51.6 billion yuan (US$7.9 billion) in April 2016, of which 86.12% consisted of bridges and tunnels and joined Mohan-Boten Laos. The border gate in the north.
The 417-kilometer Laos section between Mohan-Boten and Vientiane operates at an annual speed of 160 km and an investment of 37.4 billion yuan. Corning, the head of the fifth department of CREC4, said.
As a demonstration project of China’s high-speed railway “going out” strategy, the China-Laos Railway is the result of cooperation between China and Laos under the BRI. She added that they will also strive to make it an important link between China and economic and cultural exchanges. channel.
“China’s goal is to build a 5,500-kilometer Trans-Asian Railway, starting from Kunming, the capital of Yunnan Province, through Laos, Myanmar, Thailand, Vietnam, Cambodia and Malaysia, and then ending in Singapore,” said Ding He, deputy project manager. For railway projects also from CREC4.
Mr. Ding said that earlier in 2009, China and Thailand began construction of Thailand’s first high-speed railway, which will connect the China Railway.
Yuanjiang Hani, Baiyun Xi, deputy director of Qiaotou Community of Honghe Street in Yi and Yi Autonomous County, said that she has a total of 3,347 people in the community. She hopes that the railway will start operations as soon as possible, making transportation more convenient and making the local economy more convenient. prosperity.
After arriving at the south bank of the Red River and climbing the huge steel truss of the Yongjiang Railway Bridge, I looked down on the valley more than 100 meters away, a little scared.
“Fear?” asked Si Ming, 46, and Shidian County, Yunnan Province, to travel with me. “Yes,” I admit, holding on to the steel safety bars around the steel trusses.
“Look at them,” he said, pointing to two young workers who were sitting on steel trusses and resting after fixing some high-strength bolts on them.
They are surrounded by safety belts and safety nets below, and they seem to be used to working at such heights with little fear.
Chen Siyuan, 35, from Wuhan, Hubei Province, China, said that after years of work on railway construction projects, he has become accustomed to working at peak times.
He earns 8,000 yuan ($1,270) a month, and he says he can support his family: his wife, his 13-year-old daughter and his 9-year-old son.
“Once the railway bridge is completed, I will pass it on the train and imagine how proud I will be,” said Chen, pointing to the 925.5-kilometer bridge of the Chinese-Laotian railway in China.
Ding He, deputy project manager of the railway project from China Railway Fourth Engineering Group Co., Ltd. (CREC4), said that during the busy period, about 200 workers participated in the construction of the 832.2-meter-long Minjiang Railway Bridge, which began on April 16, 2016. .
Ding said that there will be 56 steel truss complexes connected to the Yuanjiang Railway Bridge, spanning the V-shaped Red River Canyon in southwestern China, requiring 420,940 sets of high-strength bolts.
“Every set of bolts needs to be fixed in perfect condition to ensure complete safety of the railway bridge,” he said.
