The first target plane, the sky above Wuhan City on the Yanhuang Continent.

In the Yanhuang Continent during the Republic of China, there was a group of songs along the Yellow River and the Yangtze River: the Yellow River water is not well treated; The Yangtze River Bridge can't be repaired.

Historically, except for the Taiping Army, which had built three pontoon bridges in the three towns of Wuhan in 1852 and 1853, there has never been a real bridge over the Yangtze River for more than 6,000 kilometers. Later, in the era of Beiyang warlords, George, a German professor of the bridge department of Peking University?? Miller, leading students to measure the site of the bridge. After the Bald came to power in 1930, an American bridge expert named Waldal suggested that the Bald government should carry out the preparatory work, so they sent people to drill a few holes in the Yangtze River, and then it was silent. Of course, the Bald Men did not do nothing, and their greatest achievement was to realize the direct ferry crossing of the river by the front car of the train, and called this an unprecedented and great progress in the history of Yan Huang.

"Ah~~~ It's really troublesome, in a crowded place, I just feel shrinking." Wang Fan is very entangled in whether to quickly complete the construction of multiple Yangtze River bridges in a few days or weeks under the noses of residents in Wuhan or Nanjing.

"Are you afraid of being discovered abroad that the Red Party has 'black technology'?" Yadi asked.

"There are considerations, but not all." Wang Fan explained: "Yadi, you also know that things that go against common sense, we can use the reason that there are many people and great power, and we can generally prevaricate foreigners. But what about domestic? Those water conservancy experts are not stupid, and it is no problem to cover them up on the grounds of military secrecy and so on. But I am afraid that in the future, it will lead to the evil consequences of thinking and logic of 'how bold people are, how productive they are'. ”

"Are you worried that the Yangtze River Bridge, which was built quickly in reality, will become the evidence and confidence of the revolutionary 'delusional faction'?"

"There is this concern, and now the national compulsory education has just begun. Not to mention the common people, ordinary grassroots cadres only know a few more words or do not know any words. I don't think about physics, geometry, chemistry, etc. And even in the later generations, when the popularization of basic education was completed in the 80s and 90s, when some people threw out the technology of 'turning water into oil', many people were still convinced and deceived. Therefore, I have always been hesitant to build the Yangtze River Bridge in a few days and weeks. Wang Fan explained.

"And what if you build slowly?" Yadi suggested.

"There was a bit of a lack of time. My plan is that in 1944, Yanhuang Continent will complete most of the country's infrastructure construction, so that more than 70% of the national tax revenue can be invested in the field of daily people's livelihood, so as to realize the real 'take from the people and use it for the people', so that the people who have been poor all their lives can live a really good life. Of course, it was also in order to practice internal skills, and gradually joined the world game from the second half of 1944 or 1945. ”

"So transportation is a big problem." Yadi answered.

"That's right! It is very important to build and improve the north-south material corridor. Even without my participation, after the establishment of the Yanhuang Republic, the main plane, it still has the 1,220-kilometer-long Beijing-Hanzhou Railway and the 1,102-kilometer-long Guangdong-Hanzhou Railway. However, because Wuchang and Hankou face each other, they can only rely on wooden boats and ferries to transport supplies and pedestrians from south to north. If you use wooden boats and ferries, one has a small carrying capacity, the other is time-consuming, and due to the weather, the sailing will be suspended from time to time. I have checked the information, the real history of the main plane is only in 1956, and the railway ferry has carried more than 6 million tons of goods to and fro, not to mention now with my influence? It is not an exaggeration to add a zero to reach more than 60 million tons! In addition, in Wuhan City, which has a population of more than 1 million, the average number of citizens who rely on ferries and wooden rows to travel every day is more than 110,000. Without bridges, both macro and micro are inconvenient. ”

"If it's a pedestrian and highway only, I suggest building a tunnel across the river. The Wuhan Yangtze River Tunnel is a ready-made example. Technically, it is not difficult for me, and the robot will not be noticed by anyone underground, and the subjective shock and impact are much smaller than that of the Yangtze River Bridge on the river. Yadea came up with a solution.

"Crossing the river tunnel? That's a good idea. When Wang Fan heard the word cross-river tunnel, his eyes couldn't help but light up.

"As for the Yangtze River Bridge, you can decide it yourself, anyway, at this stage, it is not realistic to rely on the Red Party to repair it by itself." Yadea suggested, "I just checked the database. Although the construction of the first Wuhan Yangtze River Bridge took only two years, these two years were not simple. ”

"Isn't it easy? What do you mean? ”

"I mean, it's not an exaggeration to say that the Wuhan Yangtze River Bridge is a national effort. At that time, the Central Ministry of Heavy Industry was able to supply rolled steel of the required quality as accurately as possible. The Central Ministry of Communications will make every effort to supply as many ships as possible for the construction of the bridge, and cooperate with the relevant shipping aspects during construction, the Central Forestry Department will supply the timber needed for the construction of the bridge as much as possible, the Central Ministry of Fuel Industry will ensure that there is sufficient power for the construction of the bridge, and the Central Ministry of Water Resources will ensure the supply of hydrological data for the design of the bridge. Of course, these are not impossible to solve with you, but the most troublesome are the Soviet specialists. ”

"Soviet specialists?"

"Well, according to the reminiscences of Teng Daiyuan's children, the 'string drilling method' used by the Wuhan Yangtze River Bridge was proposed by the Soviet expert Xilin. Then, most crucially, the Soviet Union sent a large number of experienced water conservancy experts and skilled workers to guide and help. Although we now use various methods to abduct and bring in many Soviet workers and specialists, there is still a very big gap between us and the 'systematic' 'passing' of later generations. For example, we have a full set of mathematics textbooks from primary school to university, but most of the students are at the level of the third and fourth grades of primary school, and there is a shortage of teachers in junior high school and high school. ”

"I understand, that's why I have a headache, and it's a talent problem! Always stuck here every time. Grandma's~~ In that case, I'd better build it first and use it before learning. ”

"What do you mean?"

"As you reminded me, build more tunnels across the river, and then build bridges over the Yangtze River in sparsely populated areas to solve the problem of railways and freight roads. As for the Yangtze River Bridge in terms of people's livelihood, it can allow Red Party workers to build it themselves while exploring and practicing, so as to grasp this technology in a down-to-earth manner. ”

Two days later, Shaanxi Northwestern Polytechnical University.

Shikov, a former Soviet water conservancy expert. Due to Stalin's purge and other reasons, the family was imprisoned in a Siberian prison, and was later introduced into the country by the Red Party in exchange for food and talent. It has been more than half a year since he first set foot on the Yanhuang land, and Shikov himself and his family have become accustomed to the Yanhuang life.

Because he belongs to the technical talents urgently needed by the Red Party, their family enjoys various benefits and is given priority. Shikov lives with his wife and two children in a large three-bedroom, two-room apartment. Inside furniture, kitchen utensils, bathroom life, small household appliances are complete. Shikov himself taught at Northwestern University, his wife worked in a textile factory, and his two children attended the free compulsory public primary school established by the Red Party for free.

Shikov's salary every month is 80 merit coins, twice the income of Lao Mao and others, and his wife is 25 merit coins, adding up to 105 merit coins (equivalent to 10,000 yuan per month in later generations, but because the price is cheap, the purchasing power is equivalent to 20,000 yuan), because the rent is very cheap, only 1 merit coin per month, so they can have a lot of spare money every month to buy their favorite food, clothing, books and toys. Every time he went shopping and looked at the dazzling array of goods on the counter in the store, Shikov could not help but sigh that Yanhuang, a "backward" country, had an unbelievably strong productivity of various products in the field of people's livelihood.

"Comrade Shikov, excuse me. I would like to ask you when you were in the USSR, did you participate in the construction of a large bridge across the river? Zhao Gang, director of the school's general affairs office, asked after entering the house.

"Huh? Comrade Zhao Gang, hello! Shikov, who was correcting his homework, looked up and saw the person coming, and quickly greeted and replied: "I have participated in several projects. However, there are no large ones, and I have only participated in the design and construction of 2 medium-sized bridges and 3 small bridges. ”

"That's fine, great! In this way, the central government requires that the list of experts with experience in bridge engineering in each unit be reported, and I remember that you wrote it on your resume, so I plan to report it to you. However, you may need to travel a lot in the future, is that okay? Difficult? ”

"No, no, of course." Shikov, who has always felt that he has enjoyed a too 'beautiful' life in the past six months, and is very unsteady in his heart, heard that he needed to "dedicate" himself, and immediately expressed his position without the slightest hesitation or words.

"Then let's do it first, I'll sign you up first, and I'll notify you when there's news."

"Thank you!"

A few days later.

Shikov, who received the written notice, carried two suitcases and got on a train from Xi'an to the south along with Soviet and Yanhuang experts from other schools and factories.

Outside the city of Hankou, on the side of a hill near the Yangtze River, there is a temporary camp for construction workers. It is also a large-scale comprehensive construction base built by Wang Fan: the color steel houses are neatly arranged, the ground of the road is paved with cement, the street lighting equipment is 100% in place, and the rainproof warehouses such as large-scale piling equipment are lined up one after another, like a group of mighty and majestic, ready to go out at any time, waiting for the arrival of the commander.

In the large conference room in the engineering base, the bridge experts at home and abroad who arrived began to look through the design plan and construction technical data of the Yangtze River Bridge. Considering the difficulty of construction and the quality of technical personnel, Wang Fan chose the design scheme of the Wuhan Yangtze River Bridge, which generally continued, but considering the navigation requirements of later generations, Wang Fan greatly increased the height of each bridge pier to prevent the situation that after the completion of the Three Gorges, large ships could not be navigated because of the height of the bridge piers.

"I agreed to use the hills on both sides of the Yangtze River to shorten the length of the approach bridge and embankment. It's just that the steel performance parameters mentioned in the plan are too high? Can it be produced domestically? Can I buy it abroad? Even if it is bought, can it be shipped in large quantities now in the war? An expert kindly asked.

"Please don't worry about the material. We have all found the source of goods and properly solved the transportation problem. Li He, who was in charge of the coordination work, explained with a smile.

"Is there too many piles to assist in the construction? Will this lead to a significant increase in engineering costs? The domestic expert, who was used to suffering, asked distressedly.

"For safety reasons, we are equipped with 120% redundancy to ensure the safety of construction personnel to the greatest extent.

"I've never heard of this 'string drilling method'? How can it be guaranteed? Why not use the 'pneumatic caisson method'? ”

"The danger of the 'pneumatic caisson method' is too great, the workers work in deep water, bear the changes in air pressure and water pressure, and are prone to blood poisoning, which is commonly known as "caisson disease", and now there is no effective treatment for this disease at home and abroad, so we have chosen a new technology 'string drilling method'. ”

"But unproven new technology is even more dangerous!"

"Regarding the validation of new technologies, we are already conducting a variety of tests on shore and in the middle of the river. The results have been compiled and can be consulted at any time. And the large-scale machinery and equipment that need to be redesigned and manufactured have also been produced, installed and commissioned. These include drill bits, drill rigs, vibrating pile drivers, etc. ”

"Although what you said is very certain, I think it is better to go to the field to see it first, recalculate it again, and then draw conclusions." Shikov, who had not spoken, expressed his opinion.

"Of course, I've got the vehicle ready, and everyone can go at any time." Li He said with a smile.

In this way, the Wuhan Yangtze River Bridge, which was built nearly 10 years ahead of schedule, slowly began in the bumpy cooperation of experts and technicians from all over the world inside and outside Yanhuang.
