But I'm sorry for my family. Colleagues reminisce about the water conservancy expert Ni Feng who sacrificed his life in flood control. He deserves to be a work expert | Ni Feng | water conservancy expert

In the torrent, the figure of a scientific researcher

——Remembering Ni Feng, a water conservancy expert who sacrificed himself on the front line of flood control

Design drawings cover half of the desktop; A yellowed, curled and missing cover of the Hydraulic Calculation Manual was spread out on the table, and the open chapter was titled "Hydraulic Calculation of Protective Engineering and River Structures"

The owner of this table is a hydraulic engineer - Ni Feng. Before each business trip, Ni Feng and his colleagues would walk by the Songhua River - the Jilin Water Resources and Hydropower Planning Institute where they are located stands by the bay.

But this time, Ni Feng will not come back.

Ni Feng. On August 3rd, Ni Feng was on his way to Qingsong Forest Farm in Kaiyuan Town, Shulan City to organize the rescue of workers trapped by floods when he encountered a catastrophic mountain flood and sacrificed himself on duty.

In a nine second video, the figure of Ni Feng appeared. He was carrying his backpack diagonally and an orange life jacket in his left hand, walking in a hurry. This is the scene on August 3rd at 21:00, and it is also his last image left for the world.

Marx said that the essence of human beings is the sum of all social relationships. Ni Feng, born in 1982, is playing a crucial role in multiple social relationships.

In the impression of his colleague Chang Wei, Ni Feng is a down-to-earth and not very talkative young man. "He is usually willing to read professional books and is a hardworking person."; In the eyes of Zhang Xiaodong, a junior college student, Ni Feng is a senior and senior who knows everything and speaks endlessly, teaching himself techniques hand in hand and always taking good care of himself.

"I really thought it was an ordinary business trip," Zhang Xiaodong recalled. "Upon receiving the notice, he grabbed his backpack and left in a hurry to go to the front line."

Ni Feng sacrificed himself on the way to the front line. Wang Bingkai, the lucky driver who accompanied him and survived, recalled that when he arrived at Xinkai Village in Kaiyuan Town, the flood suddenly rushed towards him like a black wall. "We climbed to the roof to avoid it, but soon a big wave scattered us..."

Upon learning of Ni Feng's loss of contact, Bo Rubing, Vice President of Jilin Water Resources and Hydropower Planning Institute, and his wife stayed up all night. Bo Rubing also graduated from Changchun Institute of Engineering, serving as Ni Feng's senior brother and the leader who introduced him to the field. Bo Rubing watched Ni Feng grow from a young and inexperienced student to a water conservancy expert and senior engineer for 18 years.

The past flashed by like a movie.

In 2006, Bo Rubing led Ni Feng and others to Zhongshan and Zhuhai, Guangdong to cooperate and exchange ideas with local design institutes, and participated in the task of designing seawalls. When I first arrived in the south, thorny problems came one after another. The main problem that needs to be solved in Northeast China is antifreeze, while the hydrological and meteorological conditions and design points of the local seawall are completely different. "We technicians with over a decade of experience at the time all had headaches," recalled Bo Rubing.

Without experience, Ni Feng started learning from scratch. He consulted the Vice President of the project during the day to study and design proposals; In the evening, read a large number of books and study calculation methods. Learning and working at the same time, Ni Feng quickly grew into a backbone of the hospital, and his over ten projects also received praise from the evaluation experts.

Ni Feng left the deepest impression on Bo Rubing, which was extremely dedicated and serious. "In the engineering design of Erdao Reservoir, he independently completed the comparison and selection of 12 schemes, solving this core technical problem," said Bo Rubing.

In the eyes of his parents and wife, Ni Feng is undoubtedly the backbone. His son is in fifth grade and always shouts, "I want to play basketball with my dad."; My father was bedridden for thirteen years due to cerebral thrombosis, but now he is suffering from the pain of sending someone with white hair to someone with black hair.

"He is worthy of work and water conservancy, but he is sorry for his family," said Bo Rubing with emotion.

Zhang Xiaodong's other identity is a member of the expert group dispatched by the Flood Control and Drought Relief Command of Jilin Municipal People's Government. Ni Feng is the team leader, and Zhang Xiaodong is a member of the team. A total of 9 expert groups, totaling 18 people, were dispatched by Jilin Water Resources and Hydropower Planning Institute to be responsible for the urban area and counties of Jilin City.

The work of the expert group is to use technological means to provide data support for flood control decision-making. Firstly, they need to regulate and calculate the rainfall and water conditions to determine whether there is a possibility of danger. At 16:00 on August 1st, as experts who have participated in flood control work multiple times and are familiar with the situation of water conservancy facilities in Shulan, Ni Feng and Zhang Xiaodong received a request from the municipal flood control department and rushed to Shulan City to attend the dispatch meeting. They combined the forecast from the meteorological department and calculated until late at night.

It rained all day on the 2nd. At night, villagers reported that there was a landslide in the urban section of Xilihe River. "A deputy director of the emergency bureau led the team, and we went to the scene to check the situation," Zhang Xiaodong recalled. After two people's judgment, the collapse is located outside the riverbank and there is no risk at the moment. Construction and repair can be carried out after dawn.

This is the second task of the expert group, which is to assist local prevention and control measures on site, conduct water situation analysis and risk assessment, and provide data support for whether it is necessary to transfer people and whether there is a risk of flooding in the village.

This requires a lot of experience and work practice. In the chat records between Zhang Xiaodong and Ni Feng, the reporter noticed a 51.5MB sized electronic document titled "2021 Xiejiadian Reservoir Situation". Obviously, Ni Feng saved it in the phone's memory and sent it out as soon as needed.

"He has participated in many flood control works and is very familiar with the situation of Shulan Reservoir and embankments. I often send him on-site photos and hydrological conditions on WeChat to discuss solutions," Zhang Xiaodong told Science and Technology Daily reporters.

On the evening of August 3rd, Ni Feng and his team went to Qingsong Forest Farm in Kaiyuan Town; Zhang Xiaodong, accompanied by local officials, went to Xinsheng Reservoir. "At that time, the water on the road was already over one meter deep, and vehicles could not pass through. We took a 'four wheel' ride and walked a 4-kilometer road for two hours. Later, the surging flood caused interruptions to the power and communication systems, and Zhang Xiaodong 'lost contact'.".

At that time, Zhang Xiaodong didn't even know that Ni Feng was in danger. At that time, he was also facing thorny problems. The fierce water flow is only 20 centimeters away from the top of the dam. Due to road interruptions, large machinery cannot enter and there is no time to excavate the emergency spillway. The risk of dam collapse is right in front of us.

Zhang Xiaodong cooperated with village officials to organize villagers to use sandbags to raise the dam top while laying anti-seepage film behind the dam - he told reporters that this is the last resort. This is the work of water conservancy experts on site: providing rational suggestions and technical solutions for dangerous situations in embankments and reservoirs, and minimizing risks as much as possible.

The good news is that the reservoir dam survived three rainy nights. Due to signal issues, Zhang Xiaodong did not contact the rear until August 5th, and it was only at this time that he learned of Ni Feng's loss of contact.

Residual sound

Recently, the Jilin Provincial Committee of the Communist Party of China and the Jilin Provincial People's Government decided to award four comrades, Luo Xudong, Zhou Kunxun, Ni Feng, and Zhang Zhizhao, the honorary titles of "Jilin Role Models", and carry out learning activities from them throughout the province; The Jilin Provincial Government approves Comrade Luo Xudong and Comrade Ni Feng as martyrs

The sadness has not yet subsided, and this land is facing the invasion of a typhoon. When the reporter walked into Jilin Water Resources and Hydropower Planning Institute, two engineers had already served as members of the expert group and rushed to Yongji County; The other members are waiting for instructions to depart at any time.

It only takes a few minutes to walk from the Planning Institute to the bank of the Songhua River, and Ni Feng and his colleagues occasionally come here for a walk during their break.

The water of Songhua River rolls forward in the sturdy embankment. The shore is shaded by green trees, and the scenery remains as usual. A childish, golden squirrel darted past the journalist's feet and hid in the bushes. As the wooden leaves swayed, an old man in a raincoat sat still holding a fishing rod.

In this peaceful scene, I can no longer see Ni Feng's familiar figure
