Guide: a light snow passed by, the weather in Beijing was sunny, the sun was shining, the blue sky was clear, and the new and old buildings were covered with gold and silver, glittering. On the 11th, we worked with Beijing south to North Water Diversion Project 3 Screw speed control: the comrades in the office joined the car torrent, left the West Third and fourth ring roads, and walked along the southwest 70 of Beijing Shijiazhuang expressway. At the same time, they inspected the extrusion pressure to ensure that the system pressure would not be too high for kilometers, and came to

a light snow passed, and the weather in Beijing was sunny, sunny, and the blue sky was clear. The new and old buildings were covered with gold and silver, glittering

Juma River, as the name suggests, the water is big and swift, and the horse looks at the river and flinches. But in the past, the water of Juma River flowed rapidly, which only existed in people's memory. Juma River in front of us is dry and waterless. Sand and gravel are piled up like mountains on the riverbed, and tractors run back and forth

standing on the South Bank of the river embankment, there is a cement boundary monument engraved with the words "introducing Han and ending Hebei". The stone monument was erected by Hebei Province. After running for more than 1000 kilometers, the water of the Han River flows out of Hebei Province and into its final destination, Beijing

"Hebei Province will build trunk canals to the border, and Beijing will use underground pipe culverts, and finally point out that the car interior needs to give potential users and car owners a good perceived quality to divert water into the city." Muyongmei, a senior engineer responsible for the design of the section of the South-to-North Water Diversion Project in Beijing, explained to us on site

the pipe culvert project crossing Juma River, with a length of 1.8 kilometers, will be one of the first three major projects in the Beijing section of the South-to-North Water Transfer Project. The minimum buried depth of two parallel buried culverts is more than 2.5 meters, and the design capacity is 50 cubic meters per second. The south bank is equipped with a sluice gate to prepare for the maintenance of the culvert, and the north bank is equipped with a booster pump station to supplement the power for the Han River to enter Beijing

after crossing the Juma River, the pipeline goes up 60 kilometers to the northeast and reaches the Yongding River in the western suburbs of Beijing. It is the largest river in Beijing. In history, it was called Wuding River because of the erratic riverbed and frequent disasters. Later, it was changed to this name, which embodies people's good wishes to manage Yongding River

the Yongding River, which was associated with floods in history, has already become a dry river. The Yongding river bed in front of us is covered with dead grass, on which driving school students practice driving. At that time, Emperor Qianlong of the Qing Dynasty wrote "Lugou Xiaoyue" in his calligraphy, and its stone tablet stood at the head of Lugou Bridge on the Yongding River, which said that it was one of the eight scenic spots in Yanjing. Now, because there is no water in the river, it is difficult to shine on the moon, and the beauty is no longer there

"the Yongding River, which originates in Hebei and Inner Mongolia, is dry and waterless for many years due to the increase of production and domestic water in the upstream and the interception of projects." Mu Yongmei, who is in her 30s, said, "I grew up in Beijing and haven't seen water in the Yongding River since I remember."

this young intellectual, who graduated from Hehai University, devoted himself to the engineering design of Yongding River with the complex of loving and longing for water. She drew such a picture: four hole inverted siphon, allowing the Han River to cross the Yongding River and the Daning reservoir, which is the flood detention of the Yongding River, for 2.5 kilometers

here, the relevant construction technical report has been approved by the relevant national departments, and Beijing has completed the pre construction preparation of "three supplies and one leveling". A large sky blue tent was set up on the wide and flat riverbed of Daning reservoir; Inside and outside the sub dam of the reservoir, lime marks about to be excavated were spread, and various engineering vehicles and long arm forklifts were on standby on the river embankment, waiting for the order of the State Council to announce the commencement of construction

Yongding River is the mother river of Beijing. Lugou Bridge, lying across the Yongding River, is 2 kilometers upstream of the construction site. The 485 weather beaten stone lions on the bridge witnessed the tragic scene of the "Lugou Bridge Incident" launched by Japanese militarism more than half a century ago, when Chinese soldiers and civilians rose up to resist. Today, these stone lions will also witness the first shot of the construction of the middle route of the South-to-North Water Diversion Project in Beijing, the magnificent construction scene on the Yongding River, and the great creation and world-shaking feat of the Chinese people in reallocating water resources

the culvert crosses the Yongding River and enters the urban area of Beijing. It will pass through Fengtai Railway Marshalling Station, Beijing Guangzhou railway, Beijing Shijiazhuang Expressway and cross the railway at 11 places. Its underground geological conditions are complex, the construction is difficult, and there are many buildings crossing, which is rare in the middle line

the middle route of the South-to-North Water Transfer Project is more than 80 kilometers in Beijing, and the buildings to be crossed account for three fifths of the total mileage. In particular, the Fourth Ring Road project, with a total length of 12 kilometers, is an eight Lane urban road above and an underground river will be built below. The pipe culvert used weighs dozens of tons and requires a gantry crane to lift it, which is a difficult problem in the construction of concealed excavation

Li Dawei, senior engineer of Beijing south to north water diversion office, introduced: "The most difficult thing is the underground culvert crossing Wukesong subway station. Above the subway is the pier of the Fourth Ring Road, and the underground culvert passes through the bottom of the subway station. The soil in the lower part of the subway is hollowed out, and the humidity after water is very high. Will it cause the displacement of the underground soil? Will it affect the safety of the subway station above? These technical problems are challenging, and they are encountered for the first time in similar projects in China and even the world."

the total investment of the underground Fourth Ring Road project is 1.1 billion yuan, accounting for one sixth of the total investment of the South-to-North Water Diversion Project in Beijing. The construction period is only two years, and it is required to be completed in 2006, so as to ensure that the Beijing Shijiazhuang section of the middle line project can be supplied with water before the 2008 Olympic Games, and Hebei Gangnan, Huangbizhuang, Xidayang and Wangkuai reservoirs can provide emergency water supply to Beijing

before the middle line reaches the terminal Tuancheng lake, there is an 800 meter open channel, which is the only appearance of Han River on the way into Beijing

jiaozhizhong, director of the Beijing Municipal Bureau of water resources, talked to us about the Han River entering Beijing with great passion

"the South-to-North Water Diversion Project is a great century project, and many people have worked and contributed to it. We designed an open channel so that Beijing citizens can see what the water transferred to Beijing from afar looks like, drink water from its source, and carry out patriotic education for the majority of young people. "The reason why Beijing has used pipe culverts to introduce Hanjiang River water at all costs and built an underground river of more than 80 kilometers in Beijing is mainly to protect the water quality and prevent it from pollution. The people of water source areas in Hubei and other places have protected such a basin of good water for Beijing, and we can't live up to the wishes of the people in the south!"

when we arrived at Tuancheng lake, the end of the middle line project, the sun was shining, willows swayed gently, and the ice in winter could not cover the green surface of the lake. 2. Sensor capacity, Wanshou mountain was tall and vigorous, and the Buddha fairy Pavilion had red walls and green tiles. According to comrades in Beijing, the Han River flows thousands of miles into here, and then introduces the water source No. 9 plant with a daily processing capacity of 1.5 million tons, which flows into the National Party and government organs, enterprises and institutions through the arteries of large and small tributaries, and into the homes of tens of millions of Beijing citizens

we seem to see that from the dripping source of Zhongshan in Hanyuan village, to the vast expanse of clear water in Danjiangkou reservoir, from the gurgling clear flow at the head of Taocha canal, to the living source of water, it continues to benefit Beijing. The middle route of the South-to-North Water Transfer Project connects the hearts of the people in the South and north of the motherland, the water source area and the water receiving area. The blood of the Chinese nation is interlinked, and the flowing water of the Chinese earth flows
