Later, the School of Water Conservancy of Wuhan University will become Wuhan Institute of Water Conservancy and Electric Power, referred to as Water Institute.Finally, in the 21st century, it merged with Wuhan University.
Tang Hua came to the School of Water Conservancy because Xilin, the chief designer of the Wuhan Yangtze River Bridge and an expert from the Soviet Union, also came to the School of Water Conservancy of Wuhan University on this day.
"Konstantin, hello, I am Tang Hua who has communicated with you several times in the air." Tang Hua went up to greet Xilin in Russian.
Xilin and Tang Hua shook hands, "I'm so glad to meet you. Before we met, you helped me a lot twice, and I would like to express my solemn thanks."
Tang Hua: "You are building the first bridge on the Yangtze River. You are helping China, and I am helping you for the same purpose."
"It's a pity that Director Peng Min didn't come today. He is always very busy," Xilin said, "Peng also hopes to meet you."
"I will stay in Wuhan for a while, and I will have a chance to meet you. Are you here for an academic exchange or a lecture?"
"It should be regarded as a lecture, about some new technological advances in hydraulic engineering. If the pipe string drilling method is implemented, I still need more engineering design and technical strength, and I want to find an assistant in this university."
Tang Hua: "If you want to find an assistant, I have a suggestion. In the northeast where you stayed, two railway divisions have just withdrawn from North Korea recently. If you look there, you will definitely find the person with the most experience in bridge construction in China. engineer."
Chapter No.16, submarines are really hard to build
Wuhan is China's "university city", which probably started after the founding of the People's Republic of China.
Everyone thinks that there are many universities in Wuhan, but in fact it has about the same number of universities as Beijing, but the city’s ranking in the country does not match the number of universities. This “contrast” makes everyone understand that Wuhan has many universities. impression.
Because Wuhan is defined as a regional central city in Central China, it exists beyond Hubei, and its radiating area is several provinces in Central China.
The country positions this place as an education center in central China, and opens a series of universities to invite students to study, not to allow students to work and build in place after graduation, but to allow you to graduate and go around, build several provinces in central China, building the motherland.
As for Wuhan, it perfectly fits the personality of the regional education center.Wuhan is located in the land of Jingchu, with outstanding people, extremely spicy food, cold and humid winter, and extremely hot summer.Few of the students could stand the horrible weather. They all ran away as soon as they graduated, escaped from the stove and went to participate in construction all over the country, and the talents were sent out smoothly.Wuhan will continue to guard the university as its education center in Central China.
(fog)
In the 30 years before the founding of the People's Republic of China, no, in the first 40 years, students couldn't run away by themselves.University graduates are assigned by the state, and you can go wherever you are told.
Wuhan was indeed the center of education in Central China at that time, and the college students here would disperse to Central China and Southwest China after graduation. In the 6s and 70s, most of them went to the Southwest, because the country was engaged in the third-line construction.
As for the third line...that's another huge thing, but it shouldn't be considered in recent years.
In short, the development of Wuhan and the size of the city were determined by the national plan in the first 30 years, and the national plan was determined based on factors such as economic development goals, industrial layout planning, and national defense strategy.
Apart from the heat, there is nothing wrong with Wuhan: the transportation is extremely convenient, there is no shortage of water, and there is no shortage of urban land.
At least in the foreseeable future, the development of China's Detroit and China's Nizhny Novgorod (the nuclear submarine construction base on the Volga River) should be in line with the national strategic positioning.
……
I visited Huagong and Water Conservancy College respectively, but Tang Hua did not dare to go to the headquarters of Wuhan University.
It is not because Wuhan University is a university of the Ministry of Education and the first two schools are industrial colleges affiliated to the Ministry, but because Wuhan University was demolished some time ago.
Wuhan University's radio broadcasting major and communication major were cut off and moved to Guangzhou to establish South China Institute of Technology (South China University of Technology).
Huawei has gradually expanded its scale from a TV factory, and the more people it wants.Especially after getting involved in the field of telephone switches, Tang Hua found that Huawei's demand for talents could no longer be met by Sun Yat-sen University. It was necessary to establish another engineering college, which is now South China University of Technology.
Well, two majors were cut off just now, so it's better not to provoke Wuhan University.
……
"Old Sa, the military boat is busy now, and dozens of people are busy on the berth. It seems that the situation is not so bad, right?"
In Wuchang Shipyard, Tang Hua said to the factory director Sa Benqi with a smile.
"It just so happened that we took over the task of building a Yangtze River ferry, which temporarily solved the problem of unemployment," Sabenqi said, "but the ferry was not a big project ten years ago."
300-ton Yangtze River ferry, flat-bottomed iron hull, single-engine and single-axle.
Not only is the ship small and does not have much technical content, but the materials used in military ships are not considered high-end.The main engine is a Soviet diesel engine shipped from Dalian, the shafting and propulsion propellers are shipped from Shanghai (the propellers for 300-ton ferries can still be manufactured in Shanghai), and the steel for ships is made by Hanyang Iron and Steel Company (soon to be transformed into WISCO), except for the keel The steel used is a bit particular, and the others are not very good. The hull is simply made of wrought iron.
Tang Hua: "No matter how low-level the ship is, at least it can give engineers and workers the opportunity to practice their skills. But just put a little thought into the construction process. You can also build these small broken ships as warships, so that the workers can constantly improve their skills. Raise the requirements.... Dig another berth and open two inland ship production lines."
Sa Benqi: "Huh? Another slipway to build inland ships?"
Tang Hua: "On the one hand, it is the need for construction. WISCO's project has reached the stage of high-speed construction, and soon a large amount of materials and machines will be transported to Wuhan for installation by water. After installation, it will be put into production. Coal transportation and steel transportation are needed There are a lot of inland river freighters. On the other hand, as I said just now, practice hands. I just read that for this level of inland river ships, 20 to 40 people on the berth are enough. The labor of [-] people."
Sabenqi: "Understood."
The Ministry of Heavy Industry directly grasped the national key shipyard in Wuhan, and now it is building inland river freighters and ferries...
Tang Hua: "There are a group of international students who study ships and will return to China next year. Among them are students who are studying submarines. From now to this time next year, Wuchuan will draw two teams of 15 people each to Shanghai Jiangnan Factory Go for an internship with Hudong Zhonghua. Those two factories are now assembling frigates relying on the parts and materials provided by the Soviet Union. In addition, each of them is assigned to the modernization project of 3 destroyers. The workload is very substantial and the technical level is relatively high. .”
……
Inland ships are actually not without technical content.After the dredging project of the Yangtze River channel is completed, ships with a capacity of 3000 tons can pass between Wuhan and Shanghai. At that time, barge fleets pulled by high-power diesel engine ships, large flat-bottomed ro-ro ships, and bulk carriers will all be indispensable means of transportation.
But before the diesel engine factory and WISCO could make their own wide-rolled steel plates, even if WISCO built these ships, they would only assemble imported parts.
Wuhan is different from Shanghai and Dalian. The shipbuilding industry in the latter two cities is at least somewhat basic. The current construction is from 1 to 2 and then to 10, while Wuchuan is from 0 to 1.
This going from 0 to 1 is probably the hardest, but also the most meaningful.If Wuchuan survives the beginning and grows in Wuhan, it will have a foundation for future upgrades, transformations, and expansions.
In terms of submarines, after the signing of the Sino-Soviet agreement last year, the M-class and S-class submarines. Although these two submarines are in stock of the Soviet Pacific Fleet, our naval personnel have not yet been able to drive submarines.
Two batches of submariners have been sent to study in the Soviet Union, and they are expected to study for two years. In December 1954, four submarines drove home.
That is, it was not until December 1954 that the workers of the military ship could see what a modern submarine looked like for the first time.
Moreover, after seeing the M-class small submarines and the C-class medium/small fleet submarines, the next task for military ships is not to imitate the M-class or C-class submarines, but to prepare to receive Soviet shipbuilding equipment and Type 613 (W level) medium-sized submarine drawings, and then use the materials and parts provided by the Soviet Union to assemble 2 Type 613 submarines.
In last year's naval transfer agreement, Tang Hua neglected to imitate the C-class submarine—the Soviet Union had discontinued production of this submarine a long time ago, and it was difficult to imitate it. It is better to directly ask for the W-class—the Soviet version of the German XXI submarine.
现在W级是苏联最先进的中型柴电潜艇，1950年3月首艇在高尔基市建造，1950年10月下水，1951年12月服役。
The W-class follow-up, the R-class, is also being designed and built by the Soviet Union itself. It is a bit difficult to ask the Soviet Union to transfer the introduction of the Type 56 destroyer. After our request, the Soviet Union also said that it will not be so fast.
……
Tang Hua is not alone in worrying about the submarine.
The Moscow Institute of Chemical Machinery, considered the Soviet Union's top secret "Project 627" design team had a rough outline of the hull.
В·Н·Pelegudov, the chief designer of the 627 project, looked at the wooden model made according to the first version of the drawing.
With an underwater displacement of more than 3000 and nearly [-] tons, it has an epoch-making blunt round bow.The propeller and rudder surface are a bit like the large Soviet diesel-electric submarines of this era, but the underwater speed should be able to reach a very high level.
If you look at its internal structure, you will also find a shocking bold design:
The head of this submarine is a giant torpedo tube that accounts for almost 2/5 of the length of the boat.
苏联人要把一种长度为24米、口径1550毫米、射程40~50公里、携带核弹头的T-15型鱼雷装备在627型核潜艇上，为了自卫还要安装2具533毫米鱼雷发射管。
