Chapter 1048: The Underground Labyrinth of the Capital City
To be honest, the torpedo is much simpler than the naval gun in terms of both technology and manufacturing process. In addition to some precision parts inside the torpedo, the rest is just a frame wrapped in a layer of iron sheet. As for
the naval gun, even if it is a medium-sized caliber such as 152mm, assuming a barrel of 40 times the caliber, it is almost six meters long. If you want a longer range and use a barrel of 52 times the caliber, the barrel length must be eight meters.
Even with the technological level of the 21st century, only a few countries in the world can make an eight-meter-long barrel.
First, you need a four-axis precision forging machine. First, use a mechanical forging hammer to forge a barrel blank, then use a super-large lathe at least ten meters long to process the surface of the barrel, and finally use a super-large boring machine at least 17 or 18 meters long to drill the inside of the barrel, and it must be able to pull out rifling.
Compared with the iron plate of torpedoes, the difficulty is simply heaven and earth. However, although it is difficult, the role of artillery is irreplaceable by torpedoes. Naval guns can bomb land, but can your torpedo attack land targets?
Moreover, since the advent of torpedoes, they have not been eliminated even in the 21st century. Instead, they have extended several launch modes, such as ship-launched torpedoes, air-dropped torpedoes, submarine torpedoes, and even India in South Asia claims to have developed a torpedo that is launched remotely with a missile and then enters the water to attack.
Of course, these are not the key points. Just remember that the 500 kilograms of charge of this thing is simply incomparable to the naval gun shells, and you will know how powerful this thing is.
Luo Chong listed the technical indicators one by one on paper. These are the directions that the institute needs to study in the future, but they are not projects that need to be launched immediately. Such a complex ship is a comprehensive and large project, which includes countless small projects. Its complexity is no less than the relationship between aircraft carriers and various countries in the previous life. Even if the Han tribe wants to build it, it will probably take a lot of time.
Besides, there is no need now. There are only so many resources in total. If they are all used to build ships, other things will not be able to be produced.
First of all, the newly established Chengkang County in the central part has not been built yet, and there is no way to transport molybdenum ore on a large scale, so the materials cannot be met.
Secondly, the current scientific research resources are all focused on the development of engineering vehicles, and there is no extra manpower to start new projects.
In addition, several factories are currently producing agricultural machinery at full capacity. Who has time to produce guns and cannons at this time? Besides, there is no big war now, so it is useless to build them.
Therefore, Luo Chong was not stupid enough to let them build the ship directly. Instead, after receiving the news of the successful development of molybdenum steel, he first praised them, and then told them to take it to the machine tool for some tests, such as tools or turning tools, and pneumatic hammers, good things for chiseling stones, to see if the hammer head made of molybdenum steel alloy is more durable.
As for the design index list of the new coast guard ship, Luo Chong hid it in the cabinet of his study. It is better not to take out this "desperate" killer for the time being.
It can be foreseen that in the next few years, the industry of the Han tribe will definitely serve agriculture and transportation construction. This is also the policy goal he set for the year of his life. Storing food and carrying out construction are the contents of this five-year plan. Since the plan has been issued, it must not be changed at will.
At the same time, after more than ten days of sailing, the fleet transporting slaves to the south has arrived at the dock of Takuhai County. You Zhi, the commander of the Jinwu Guard, has also received the news from Luo Chong and arrived at Dashu in advance to wait for the slaves.
Since the Xin tribe on Zhudao was destroyed by the Han tribe, the role of Jinwuwei in collecting external intelligence has weakened. Because of the loss of the enemy, Luo Chong has sent all these intelligence personnel to a deserted capital to build a palace. Originally,
this was nothing, but Luo Chong gave too few people, and the workload was so large. After working here for more than a year, no decent building has been built. You Zhi even thought that he had displeased the leader and demoted him here to build the palace.
Of course, the above are purely his fantasies. Luo Chong is not not giving others, but other places in the tribe need more people. This palace is simply a home built for him. How can he have the nerve to use all the resources of the tribe to build a house for himself?
Now that he has new slaves, he immediately sent a batch to You Zhi.
You Zhi was happy now. With the addition of 5,000 young and strong slaves, the size of his engineering team finally took shape. A clerk who came to escort the slaves said to You Zhi,
"Commander You, the leader said that he will send you a few engineering machines in two months. Then you won't need to use manpower to do the work like digging and leveling the land. Just wait to receive them."
"What? No manpower? Then why do you give me so many slaves? They can't be sent here to eat for free, right?" You Zhi asked in confusion.
"How can that be? Slaves are used to work for us. As for what they are used for, the leader seemed to have said something. Oh, yes, it was about the sewer system of the capital city. The slaves can be used to dig and let them work. I don't quite understand this either." The clerk scratched his head and thought about it, and suddenly said.
"Oh, oh, oh, I understand. Go back and tell the leader to rest assured. You Zhi will complete the task." When You Zhi heard this, he immediately remembered that there was indeed such a thing in the capital city.
Actually, the Han tribe had sewers a long time ago. When the Han tribe built its first city, Hanyang, they dug drainage channels along the streets. However, they were not proper sewers. They only dug several drainage ditches of different depths, covered with a row of stone slabs, and placed a stone slab with drainage holes every once in a while. This became the most basic drainage system.
However, Hanyang was only a small city after all, not even the size of a palace, so how could it be compared with the capital city?
Luo Chong defined the capital city of the Han tribe as the largest city in the world. After all, it was the capital of the empire in the future. It must be very large in scale, and the population living there might exceed several million. Such a large city would not work without a sound sewer.
Therefore, the sewer that Luo Chong asked them to build this time was not the simple drainage channel in Hanyang before, but a real urban drainage system, a sewer comparable to an underground maze and combined with civil air defense fortifications. It could be used to discharge sewage at ordinary times and to escape at critical times. In general, it was no problem to say that it was an underground tunnel.
Of course, the idea of ​​connecting civil air defense fortifications and sewers is just an idea. If they were really directly connected, the basement would have been flooded with sewage long ago. However, it is not difficult to use the sewers to escape and avoid heavy artillery. You just need to build the civil air defense fortifications and sewers closer together, and when you need to escape, you can temporarily use explosives to break a hole.
Escape passages like this one are just in case. After all, Luo Chong has led the world's technology a little astray. In the foreseeable future, the Han tribe will definitely be an industrialized country with heavy artillery and machine guns. For such a force, building an underground shelter is nothing.
And since You Zhi is in charge of the construction of the imperial palace, it is natural that this matter falls on him.
After receiving the five thousand slaves, he immediately led his men to the direction of the imperial palace in the capital. The placement and training of the slaves was directly handed over to his subordinates. You Zhi directly found several foremen in charge of the construction of the imperial palace, that is, the group of skilled craftsmen who helped Luo Chong make the miniature sand table model of the imperial palace.
After arriving at a temporary project command center, You Zhi spoke to several people straight to the point.
"The leader said that in two months, there will be a batch of large-scale machinery and equipment coming to dig the soil and level the land, so we can put these basic projects aside for later, and these slaves don't need to be used for those projects. The leader means that we should use these slaves to dig the sewer system. You are the master craftsmen in charge of the specific project. What do you think?"
"This is easy. Since the leader said to dig, then we will dig. What's there to say? I have no problem." One person immediately expressed his opinion.
"Yes, in fact, this sewer should have been dug a long time ago. First, it is at the bottom. If the sewer is not repaired, how can we build things above? Second, the earth dug out when digging the sewer, according to the drawings given by the leader, the scale of this sewer is not small, and a lot of earth can be dug out. If we wait until the surface buildings are built, I will worry about where to put this earth." Another person immediately supported and said.
"Well, I don't object to digging a sewer, but brothers, how should this sewer be dug? Is there any technical problem? Don't forget that this is underground. How can people identify the direction after going down? What if the digging goes off?" An older kiln worker immediately raised his question.
"Well, this is indeed a problem, and it's not just the left and right deviations, but also the up and down slopes. You must know that water flows to the lower place, and this sewer must have a slope to allow the sewage inside to flow by itself." After hearing this, someone raised another question.
"Yes, the scale of this sewer is too large. Let's think about how to solve these problems, otherwise it will be difficult to construct." You Zhi frowned when he heard this. Although he was not responsible for specific engineering projects, he was the general manager of the entire project. If the people below could not complete it, he would not be able to report it. So he could only mobilize everyone to work together.
Everyone frowned and pondered when they heard this. Some people stood up and circled around the sand table model, as if they were verifying the feasibility of their ideas in their hearts.
Not long after, a young man really came up with a solution. This man was also a carpenter who came out of the Liuyang Shipyard. He suddenly said.
"I have an idea that should be feasible. Everyone listen and help analyze it."
Everyone nodded when they heard this, and the young carpenter continued.
"First of all, we must first clarify the structure of the sewer. It is composed of underground horizontal and vertical passages that extend in all directions, and vertical shafts connected to the ground, right?" Seeing everyone nod, he said again.
"And these vertical shafts are where the sewage comes in. They are distributed along the streets in the city, so we can first mark the location of the streets, and then find the locations of these wellheads along the streets. According to the leader's requirements, these vertical shafts will be covered with iron manhole covers of uniform specifications in the future. Am I right?"
Everyone nodded again. You Zhi was listening beside them, and then said, "Well, I understand after hearing what you said, but what you said only solves the problem of locating the sewer shaft. But what about the underground direction and slope I just mentioned?"
"Don't be anxious, Commander You, this project has to be done step by step, right?" The young man smiled and continued.
"This sewer project is very long. It can be said that there are as many streets and alleys in the city as there are sewers. We can't dig from one opening and then not come out. That would not only make it difficult to locate, but also inconvenient to transport soil and people to the ground. So we can use the segmented construction method."
At this time, the kiln worker who asked the question earlier suddenly realized, "Oh, I understand. You mean, we dig from those vertical shafts at the same time, and then dig from the position of the vertical shafts to both sides, so that we can open up the horizontal passages between each vertical shaft?"
Everyone understood it immediately and agreed.
"Not bad, not bad, this method is good. It can greatly speed up the progress of the project and reduce the construction period."
"Yes, and in this way, it is easier to manage personnel. We can divide the workers into groups, let them work in groups of several people, and be responsible for a vertical shaft, and then dig horizontally on both sides.
"In addition, this can also divide the particularly long sewer into sections, which is convenient for us to locate the direction of the underground. It is difficult to locate the entire street, but we can always think of a way to divide it into sections. "
When everyone heard the young carpenter's construction plan, they all began to agree with it. However, when everyone finished speaking, they found that the two most important problems seemed to have not been solved yet.
So at this time, the carpenter said again, "Don't worry, I haven't finished yet. Regarding the problem of underground positioning, I have actually thought of an idea just now. First, we draw a line on the ground to find a point, and then use a plumb bob to position it to dig a straight vertical shaft.
"After digging the vertical shaft, we can draw a line on the ground, and then use a spirit level and a plumb bob to measure the depth of each well, and locate the slope by making them deeper than the other, which makes it easy.
"As for the horizontal and vertical positioning, this is also easy, but we need the leader to make us a tool, a tool specifically for this kind of work."
"What tool can guide the direction underground? "Everyone asked curiously.
The young carpenter smiled proudly, and then said directly, "Of course it's light. Only light doesn't turn. It's said in the science textbooks at school that light always shines in a straight line. If we use the light to always shine in one direction, won't the people below be able to dig in the wrong direction?" Everyone
's eyes lit up when they heard this. Yes, why didn't they think of it? Use light to guide the direction!
