Chapter 242 Dock and Connection
Gansu Province, Minqin County.
A large area near the western desert was already planted with a lot of soybeans.
The soybeans that had just grown for more than a month have dyed the nearby yellow sand into green.
In the open space near the west side of the county town, a continuous industrial area of more than ten kilometers is under construction.
In addition to industrial areas, there are also supporting staff communities, large water storage stations and other facilities.
As for why such a huge industrial facility is built locally, on the one hand, it is to get close to the origin of raw materials, and on the other hand, it is to keep it confidential.
Xiansi soybeans are very important. Not only does Hailufeng Company think it is very important. The official also believes that Xiansi soybeans are related to many strategies. For Hailufeng Company, it plans to build an isolated industrial zone and planting area in Minqin County. The official support is fully supported by the idea.
This support includes changing the industrial structure of Minqin County. Starting next year, Minqin County will no longer allow crops other than fairy beans, fairy soybeans, and natural-growing grasses.
The reason why other crops are not allowed is to transfer local agricultural water share to domestic and industrial water, and increase the local population carrying capacity upper limit.
You should know that Minqin County currently has a population of only 170,000, while the annual available water resources in the local area is only 120 million cubic meters. After deducting 30 million cubic meters of ecological water replenishment, there are still 90 million cubic meters left.
You cannot have both fish and bear's paw.
Since you want to develop industry, you can only sacrifice other local agriculture. Not only does the planting industry not allow it, but even the animal husbandry industry does not allow it, because raising pigs, cattle and sheep requires a large amount of fresh water.
As for whether the ban on other agriculture and animal husbandry will cause local farmers to lose their livelihoods, there is no need to worry about this. Local farmers are either recruited to work in the farm or work in the service industry in the city.
In the future, the entire Minqin County will develop a series of high-tech industries around Xianshi soybeans.
Including bean silk fabrics, high-strength modified bean silk fiber materials, composite materials, soybean oil refining, biodiesel refining, high-strength ultra-light parts production, airship manufacturing, etc.
These industries are estimated to require more than 100,000 industrial workers, so they must ensure their daily water and the industrial water for this high-tech industrial park.
In the planting area near Xiansi soybeans, a desert isolation belt with a width of more than ten kilometers is also reserved.
The edge of the isolation belt is planned with three layers of barbed wire, outposts, fire points, drone shielding towers and independent monitoring networks.
These facilities are currently under construction.
Including the pressing factory and the soybean meal preliminary treatment factory, they are all inside this isolation belt.
After all, the value of fairy-silk soybeans is too high, much higher than fairy-silk soybeans. It is necessary to delay the time when foreign forces obtain fairy-silk soybeans as much as possible.
As long as the early technology and patents are controlled by the domestic market and the industrial layout is completed, even if foreign countries obtain fairy soybeans, they will not be able to threaten Cyris in related industries.
At present, a total of 800,000 mu of fairy-silk soybeans have been planted in Minqin County, which will increase to 3 million mu next year. The subsequent planting scale will be adjusted according to market changes and industrial needs, but the overall planting scale will not be less than 1,000 Ten thousand acres.
The 800,000 acres of fairy silk soybeans this year can be extracted about 80,000 tons of soybean silk fibers. After modification and treatment, they will be almost 120,000 tons of high-strength soybean silk fibers.
In order to promote the development of the Minqin County Dousi Industrial Park, Hailufeng Company has lent 20 billion yuan of special development funds from local banks, and at the same time introduced state-owned assets to enhance the overall strength of the entire industry.
In the current shareholding structure of Hailufeng Minqin Development Group, Hailufeng Company holds 51% of the group's shares and management rights, and state-owned assets hold 49% of the shares as financial investment, and participates in financial supervision.
Such huge investment has made the entire industrial park grow like mushrooms after a rain.
In order to catch up with the progress, the construction workers in the entire industrial park reached tens of thousands.
In order to support the implementation of this project as soon as possible, the official temporarily joined a large number of freight high-speed railways on the Lanzhang High-speed Railway, which was just opened to traffic this year, using the high-speed railway to transport steel bars, cement, various construction materials, as well as various daily necessities. .
This allowed the progress of the entire project to be carried out at a speed visible to the naked eye.
The first phase of the oil pressing plant and the soybean meal initial treatment plant has been completed, and can process 1 million tons of soybeans and 1 million tons of soybean meal each year.
At this time, the airship manufacturing factory invested by Hailufeng Company itself was also in full swing.
However, this project is not that fast, mainly because the docks of several airships are very large and require a completely airtight indoor dock.
Because these new airships being designed are very large.
Blue Whale 1, with a maximum load capacity of 200 tons, a hydrogen airbag of 270,000 cubic meters, a length of 275 meters, a diameter of 48 meters, and a maximum take-off weight of 320 tons.
Blue Whale No. 2, with a maximum load capacity of 500 tons, a hydrogen airbag of 670,000 cubic meters, a length of 350 meters, a diameter of 60 meters, and a maximum take-off weight of 800 tons.
Blue Whale No. 3, with a maximum load capacity of 2,000 tons, a hydrogen airbag of 2.7 million cubic meters, a length of 580 meters, a diameter of 100 meters, and a maximum take-off weight of 3,200 tons.
This is the three types of airships currently being designed by Hailufeng Airship Manufacturing Factory.
Due to the different processes, in order to ensure that the strength of the airship skeleton reaches maximum, the skeleton must be weaved, and then the airship skeleton can be formed integrally to avoid structural defects in the skeleton.
Only by manufacturing the airship skeleton in this way can we ensure the maximum compression of the airship's self-weight and increase its payload.
There is not a big problem in length, the key is the height and width generated by the diameter.
For example, Blue Whale No. 3 has a diameter of 100 meters, plus the cargo fixture and autonomous driving bin at the bottom, the height must reach about 105 meters, plus the redundant height and width of the construction area. The width and height of the entire dock must reach at least 150 meters.
This large-span upper dome structure tests the difficulty of construction and the material strength of the building.
Considering cost issues.
Hailufeng Company does not use traditional steel structures and steel cables, nor does it use carbon fiber, but plans to use modified soybean silk fiber.
The foundation and base of the bottom layer are constructed with reinforced concrete, while the walls and skeletons in the upper half are made of soybean silk fiber composite material, plus internal and external fire-resistant coating and external ultraviolet-resistant coating.
The design team responsible for designing this dock, after careful calculation, it was found that after using new materials, the weight of the upper half of the indoor airship dock would be reduced by about 80%, and the overall construction cost of the factory could be reduced by about 60%.
The reason why the cost has been reduced so much is that the structure of the upper part is 80% lighter, so the weight required by the foundation will be reduced by 80%. The cost of foundations with different load-bearing weights must exist. A huge difference.
Hailufeng's modified soybean silk fibers have a production cost of about 8,000 yuan per ton. Among the composite materials, the added amount of modified soybean silk fibers is generally between 30% and 80%.
The ex-factory price of new material building components of Hailufeng Minqin Group is 20,000 yuan per ton, and the gross profit per ton is about 12,000 to 14,000 yuan.
This price is not high, and those traditional large-span steels cost four or five thousand yuan per ton.
And the high strength of the new material allows the components to be manufactured very lightly, which is conducive to transportation, loading and unloading and installation.
If it is traditional high-strength steel, steel factories are willing to manufacture large-span integrated components, and there are probably not many cranes that can be lifted.
The integrated components using new materials are about 80% lighter than steel components of the same proportion, and even small cranes can play with them.
However, at this stage, the component factory of Hailufeng Minqin Group has not been completed, and the raw materials have not been planted. Therefore, the first half of the airship dock can only wait for the local fairy silk soybean harvest in September before production and installation.
At the same time.
The bean silk laboratory at the headquarters of Hailufeng Company has also used the fairy silk soybeans harvested in the second quarter of the experimental field these days to work overtime to produce a lot of modified bean silk fibers, fabrics, components and other things.
In a town in Lufeng.
The company has set up a temporary airship experimental base here.
More than 50 aviation engineers, airship designers and technicians recruited from across the country are assembling a large airship in the open air.
Jiang Miao also came here for inspection.
Wan Gaofeng, general manager of Hailufeng Airship Company, Hou Xin, technical director, and Yang Yuanzhen, head of Dousi Laboratory, are all here.
This site used to be an abandoned quarry. Jiang Miao and others stood halfway up the mountain and could overlook the quarry valley. Several large tower cranes were set up inside the valley, and several cranes of different specifications were used for lifting auxiliary components.
"Boss, the keel of Experiment 1 has been laid. We have also installed all the airbags, and the customized hydrogen liquefaction storage tank and inflatable and exhaust equipment are in place." Hou, technical director of the Airship Company and designer of the Blue Whale Airship. Xin clearly introduced the progress. "Can you test it now?" Jiang Miao asked this because Wan Gaofeng, general manager of the Airship Company, invited him to participate in the test flight ceremony two days ago.
Hou Xin nodded: "Okay, there is a skeleton and airbag, plus a part of the control system, so you can test it. Other skins and electric propellers will be tested later."
Hearing this, Jiang Miao also reacted: "In other words, today is mainly to test the payload?"
"Yes, boss."
"Depending on the current situation, it will take another one or two hours, right?" Jiang Miao estimated the situation at the scene.
"Yes, after all, it will take some time to fill 2.7 million cubic meters of hydrogen."
Jiang Miao picked up the telescope and looked at the valley about one kilometer away, which was underway. Inflatable operation, dozens of high-power industrial fans, plus pipelines, are constantly breathing.
Obviously, Hou Xin knew very well the power of 2.7 million cubic meters of hydrogen. If an explosion was accidentally triggered, its power would be approximately equivalent to more than 8,000 tons of TNT explosives.
No mistakes, one poem, one post, one content, one in 6, one book, one bar, one read!
Therefore, they strengthened ventilation to avoid the accumulation of too much at the valley bottom after hydrogen leakage, causing the concentration to reach the critical point of explosion.
Many hydrogen concentration detectors have been installed in advance on the valley bottom and on the airship skeleton, and several staff members are always watching the feedback data of these detectors.
The behind this half-mountain observation deck is an explosion-proof bunker created by natural caves.
This is also the reason why the experimental base is set up in the valley. There are fewer residents in the area. Hailufeng Company has paid for dozens of local villagers to move to other places to live, just because they are worried about hydrogen explosion. question.
Time passes by minute by minute.
Two hours passed without realizing it.
The staff responsible for monitoring the inflation progress of the airbag reported to Hou Xinhui: "Director Hou, the inflation has been completed, and the current hydrogen concentration of the skeleton does not exceed the set value and is within the safe range."
"Good, continue to monitor." Hou Xin picked up the intercom: "Counterweight group, please return after receiving it."
"Counterweight group received."
"Counterweight group According to the original plan, the No. 1 test plan will be implemented. ”
"The counterweight team received it."
Several counterweight team staff connected the airship shelf cables to the container underneath.
A total of 50 containers are connected, and the weight of each container is 20 tons, which is a total of 1,000 tons.
"Director Hou, the counterweight connection is complete."
"Recheck the connection again."
"Yes."
Half an hour later. "Director Hou, the inspection has been completed and the connection meets the requirements."
"Evacuate."
Evacuate with the counterweight team.
"The evacuation is completed."
"Received." Hou Xin then ordered: "The fixed group began to relax the tied cables in an orderly manner."
"The fixed group received." >
The 8 tied cables loosened little by little, the airship began to float upwards, and the 1,000-ton counterweight also slowly moved upwards.
Jiang Miao's telescope looked at the skeleton under the airship, especially the load-bearing beams. The weight of thousands of tons was not stressed.
In the telescope lens, the load-bearing beam does not show obvious deformation, which is obviously not exceeding its tolerance limit.
The detectors installed on these load-bearing beams also did not detect too severe deformation data.
The test continues.
The staff continued to increase the weight of the counterweight and tested whether the 2.7 million cubic meters of hydrogen airbag had a payload of 2,000 tons.
Three hours later, the weight of the counterweight finally exceeded 2,000 tons, but the configuration team continues to increase the configuration, because the counterweight needs to be considered later skinning, autonomous driving bins, electric propellers, and auxiliary control equipment. , battery box and other weights.
It was not until the total weight of the experimental airship reached 3250 tons that the airship was pressed near the ground by the counterweight and could not continue to float.
But when the total weight of the airship is reduced to 3150 tons, it will continue to float upward, which is obviously basically the same as the designed floating critical point of 3200 tons.
After the freshly released test data, Hou Xin reported to Jiang Miao: "Boss, the maximum load-bearing capacity is basically in line with expectations. When floating to an altitude of 1,000 meters, the airship payload is reduced due to the decrease in air density and airship payload. It has dropped by about 11%. If you want to safely cross areas with higher altitudes in the future, you may need to reduce some of the payload."
"Yes." Jiang Miao touched the stubble on his chin, and he asked with a smile. Question: "Director Hou, do you think our company's airship can be used for canal connection?"
"Canal connection?" Hou Xin was stunned for a moment, then thought carefully again and passed After a while, he picked up his phone and used the AI on his phone to investigate some of the current situation of inland transport ships.
After browsing the data of various inland transport ships collected by AI, he raised his head and replied: "Boss, if the 2,000 tons of near-ground payload of Blue Whale 3 is used, the payload of 1,500 meters above sea level is 1680 tons is an inland transport ship that can carry 1,000 tons of diptons. Because the inland transport ship with 1,000 tons of diptons, plus its own weight and fuel, the limit is about 1,600 tons, generally around 1,400 tons to 1,500 tons." >
Wan Gaofeng, who was standing by, was also analyzing this idea. He expressed his own views: "At present, among the domestic canals, the Ganzhou Canal, the Jiangxi-Zhejiang Canal, and the Hunan-Guangxi Canal are still under construction at the altitude of the watershed. The heights are around 1,000 meters. If you can use airships to connect, you can really consider it. In terms of cost..."
Hou Xin added the data to Wan Gaofeng: "In terms of cost, I just checked it , The cost of passing the lock of the Three Gorges of the Yangtze River is more than 400 yuan for a transport ship with a load of 1,000 tons. If the container ship is a little lower, it is usually 350 yuan."
"Is this how?" Wan Gaofeng knew the load cost of the Blue Whale Airship:
"Our energy consumption cost per kilometer is about 0.01 yuan. If we want to bypass the Three Gorges Dam and take 50 kilometers as the range, the energy consumption cost per ton will be 0.5 yuan, with 1,500 tons as the standard. The energy consumption cost will be 0.5 yuan. It is 750 yuan, plus depreciation costs and other expenses, and the cost is about 1,000 yuan, so you can really consider it."
Hou Xin nodded slightly: "Nothing wrong, especially on both sides of Nanling and Wuyi Mountain Due to the limitations of the terrain, even if the canal is built, the passage of the canal will have a limit in the future. "
While Wan Gaofeng is not a practitioner in the inland transportation industry, he is slightly After analyzing it, you will know that this kind of canal with dense locks has very low navigation speed and navigation efficiency.
He continued: "Our large airship has a lot of hydrogen, and it is estimated that it cannot get close to the city. It can only be used as a supplementary transportation in areas with large and sparsely populated areas. The boss envisions the canal connection business, There is indeed great potential."
"Well, if you can plan a safe low-altitude channel near the canal, you can consider gondola connection." Wan Gaofeng added:
"Of course, if you can design a container cage that can be transported quickly and used on a container ship, you may be able to lift the container directly without raising the ship together, and the cost can be reduced by about one third."
Yang Yuanzhen, who had been silent all the time, suddenly spoke: "In fact, finding the shortest low-altitude channel near the lock is the most cost-effective solution."
Hou Xin shook his head: "Yes! He is just worried that the dam management will not be Agree that the airship is too close. After all, during the lifting process, once thousands of tons of items are smashed down, the damage to the dam will be too serious. "
Wan Gaofeng also knows that the transfer distance is the key: "If it is near the lock, The transfer accumulated within 20 kilometers, so our cost was very close to the lock."
After everyone's discussion, Jiang Miao immediately made a decision: "The airship company will form a research team with the logistics department, and follow the Project to connect airships in the canal. ”
"Okay." Wan Gaofeng naturally had no objection.
