in Western Hunan, there are two phoenix: one is written by Shen Congwen, One is in Huang Yongyu’s painting

on December 6, Zhang Ji Huai high-speed railway connecting Zhangjiajie, Jishou and Huaihua will be opened to traffic

another Phoenix, spreading its wings — surrounded by mountains, the ancient Phoenix Station on the Zhang Ji Huai high-speed railway line looks like the legendary “divine bird”

“eight mountains, one water and one field”

in Western Hunan, the mountains are beautiful; The terrain in Western Hunan is dangerous

the 247km Zhang Ji Huai high-speed rail line winds through the clouds, stringing 162 bridges and 118 tunnels

Wang Yinghe, 38, said, “we have measured every mountain road, subgrade and tunnel with our feet.”

for six years! “China’s most beautiful poverty alleviation high-speed railway” has become a reality from drawings

six years! Wang Yinghe leads the geological survey and design team of tiesiyuan, like a Phoenix, to “spread its wings” between Chongling and Jue gullies in Western Hunan for more than 300 days a year

■ “he wrote his most brilliant paper in Zhang Jihuai”

in early November, the reporter of Changjiang Daily drove to visit Fenghuang ancient city station, Guzhang west station, Furong Town station and other stations along Zhang Jihuai high-speed railway

all these stations in the mountains are built by digging mountains

Wang Yinghe, deputy chief engineer of geological subgrade design and Research Institute of tiesiyuan, has been here countless times. “When I first came here, there was only mountain”

in 2015, Wang Yinghe became the design director of geological subgrade discipline of Zhang Jihuai high speed railway

Wang Yinghe said that the geological conditions along Zhang Jihuai high-speed railway are extremely complex: the total length of bridges and tunnels along the whole line accounts for 90% of the total traffic mileage, and adverse geology such as karst underground rivers, rock pile landslides, dangerous rocks and rockfalls are widely distributed along the line

protection design of dangerous rock and rockfall in 118 tunnels and 173 openings; The slope protection design of 162 bridges and 158 bridges…

a series of numbers came out with both feet by Wang Yinghe and the team

97%! The high accuracy of advanced geological prediction effectively avoids the construction risk

standing in front of Furong Town and looking around, the reporter was surprised that it was more than 80 meters higher than the surrounding counties

survey and design is the “leader” in railway construction! Wang Yinghe takes Furong Town station as an example

Wang Yinghe said that the site selection of Furong Town station is a difficult problem: the line must pass through Daqingshan with strong karst development and dense underground river network

the front and back of Furong Town station are respectively connected with two karst tunnels and a bridge across Youshui River Valley. Wang Yinghe said that from the perspective of geology, the site selection of the station is too low. When crossing the karst tunnel, the risk of mud water suddenly gushing out during construction and operation is higher; If the site selection is too high, it will affect the use of the station, as well as the later bridge selection and construction cost

during the survey of Zhang Jihuai high-speed railway line, Wang Yinghe and his team spent one third of their time in Furong Town: they conducted 588 square kilometers of geological survey, completed special studies on Karst Hydrogeology and environmental geology in Furong Town, and conducted ten rounds of safety demonstration of station setting scheme in combination with geophysical exploration and drilling results

due to the successful geological route selection during the survey, only one large karst cavity was encountered in the construction of 12 km long Yongshun tunnel, which was indicated in the preliminary survey data; Accurate geological prediction and early warning during construction. After the cave was revealed, they went deep into the cave for the first time to accurately find out the shape, engineering geology and hydrogeological characteristics of the cave, which provided a solid foundation for determining the cave treatment scheme

“President Wang is busy with professional coordination and design communication during the day, and only after 11:00 p.m. can he have time to review the drawings.” Zhang Qian, a professional partner of Dilu, said that Wang Yinghe fainted in the office at noon when the construction drawings of Furong Town were completed

Wang Yinghe said that in the past six years, the team has completed 454 volumes of survey reports and 313 volumes of design drawings. “The survey reports and drawings are spliced together for several kilometers.”

Zhu Jiang, the overall design director of Zhang Jihuai high-speed railway, said that in the past six years of Zhang Jihuai, Wang Yinghe published many papers, but “he wrote his most brilliant papers in Zhang Jihuai and in the mountains”

during the survey in Zhangjiajie, you can see the tourist cable car shuttling through the mountains every day, “when can you sit up and see the scenery?” Wang Yinghe said that after three years of this wish buried in his heart, the project came to an end in 2018, and they felt the beauty of Tianmen Mountain on the cable car for the first time

■ “since you choose this road, you must stick to it”

“no matter which job you choose, you will experience a painful period. As long as you work hard, you will make a difference.”

after 12 years, Wang Yinghe still remembers the sentence given to him by his mentor

in 2009, Wang Yinghe, who graduated from Hehai University with a doctor’s degree, had three employment options: go to college; Go to a design institute in Shanghai; Go to tiesiyuan

after thinking for three days, Wang Yinghe made a choice, came to Wuhan with a shoulder pole, walked into tiesiyuan, and became the first doctor of geological subgrade design and Research Institute. “China’s high-speed railway development has entered a golden period, I studied geotechnical specialty, and I believe I can make a difference.”

in the summer of that year, Wang Yinghe participated in the first project after joining the post – Guangdong Western Coastal Railway

Wang Yinghe’s hometown is located in Yuexi County, Anqing City, Anhui Province, at the foot of Dabie Mountain. Although he had climbed mountains and forests since childhood, he was not used to the work in the mountains at first

“in the mountainous area of Guangdong in midsummer, in order to prevent leeches, we should not only wear long clothes and trousers, but also tighten the trouser legs.” Wang Yinghe occasionally lost when communicating with his classmates working in the city

“compared with Zhang Jihuai high-speed railway, these were nothing at the beginning.” Wang Yinghe said that a compass took him out of the “painful period” mentioned by his mentor

that was an experience in Yuhuang mountain in Sanmenxia City, Henan Province

in the spring of 2012, the Haoji railway running through the north and South entered the preliminary geological survey stage

at 4 p.m. that day, when he and a colleague finished the geological survey and prepared to return, they “couldn’t get out of the mountain anyway”

“at that time, there was no navigation system in my mobile phone.” Wang Yinghe said that the night was getting darker and there were wolves on the mountain

in fear, two young men with wooden sticks decided to “rush in one direction” with the help of a compass

two hours later, they finally saw the car lights on the road

Zhang Yong, the design director of bridge discipline, and Wang Yinghe had the experience of surveying together

in Zhang Yong’s eyes, geological survey is more like “jungle exploration”: there are dense mountains and forests. When going up the mountain, he never leaves his hand except with survey tools

Wang Yinghe explained that in addition to beating snakes, the wooden stick is also used to check the animal trap laid by hunters

Wang Xiaoting, Wang Yinghe’s wife, once received a photo from her husband. The sign “there is a wolf clip on the mountain, and the white clip is dead” in the photo worried her

Wang Xiaoting didn’t know that her husband had experienced more dangerous things: traveling in the valley, the falling boulders on the mountain would suddenly fall in front of her

“I saw with my own eyes that two sheep were smashed not far from me.” Wang Yinghe said that his fear was unforgettable

in 2011, after Wang Yinghe, 28, became a senior engineer, units successively extended “olive branches” to him, and he declined these “no need to enter the mountain” invitations one by one

Zhang Jihuai’s high-speed railway has become a reality from the drawing. Wang Yinghe can’t help thinking of the compass in those years

the doctor who came out of the mountain had already understood the truth from the second half of his mentor’s sentence: “if you have firm confidence and rush in one direction, you will succeed.”

■ “I also jump with them, laugh and cry”

a group of Tujia cadres and villagers, dressed in national clothes, sing around a group of “people who come to build the railway”, Jump, laugh…

Wang Yinghe said that such a scene appeared more than once during the scheme study of Furong Town, “I also jumped, laughed and laughed with them until tears came out”

Wang Yinghe said that such a scene reminded him of a plate of bacon deep in the mountain

“that dish of bacon is really delicious.” after many years, the aroma of bacon still remains in Wang Yinghe’s memory

during the survey of Shiyan Yichang railway, Wang Yinghe and two colleagues entered a deep mountain in Fangxian County, Hubei Province

at about 2:00 p.m. that day, the party was hungry and accidentally met an old man living alone in his 70s

seeing three “children from the city”, the old man was happy and had to stay for dinner, “I haven’t seen anyone for more than half a year”

Wang Yinghe recalled that the old man took out the bacon he was not willing to eat

after dinner, the old man resolutely refused to accept money. “It’s not easy for children in the city to go to the mountains to build railways”

railway is the expectation of generations of mountain people

at the high-speed railway stations built on the hillside of Zhang Jihuai high-speed railway, the reporter found an interesting picture: the locals in the scenic spot regard the newly completed station as a “clock in point”

“many of them have never seen a high-speed train.” Wang Yinghe thought of himself when he was 22 years old because his hometown had no railway

Wang Yinghe grinned as she watched the villagers punch in

Zhang Jihuai’s twin daughters were born in the year of the preliminary survey of the high-speed railway

Wang Yinghe often compares this railway to his daughter, “it changes every time and is very kind”

during the field work of more than 300 days a year, Wang Yinghe was moved and engraved with the memory of tears

in 2016, when her grandmother was critically ill, Wang Yinghe rushed back to her hometown, but failed to meet the old man who brought him up

in 2018, before his death, his mother kept talking about his name. Wang Yinghe leaned over the hospital bed, and the old man could not recognize his son looking forward to the night

in February 2020, the bus to return to work in Jishou drove alone in the empty streets of Wuhan, and Wang Yinghe burst into tears

Wang Yinghe said that in China’s current railway construction, many specialties no longer need to climb mountains, but geological survey is the only exception. “Although remote sensing, UAV and other technologies are helpful to geological specialties, the mountains are lush with vegetation, and it is still necessary to rely on feet to obtain first-hand geological data”

Zhang Jihuai high-speed railway was opened to traffic, and Wang Yinghe has begun to participate in the preliminary study of Yichang Fuling section of high-speed railway along the river

“a man should have Ling Yunzhi to protect the mountains and rivers and the villagers.” just as he sent this circle of friends, Wang Yinghe stepped into the mountains again
