Chapter 369: An accident is a natural and man-made disaster
Theoretical people will inevitably come up with many hypotheses, that is, they will make assumptions based on what may happen without actual data.
Of course, Sun Wu was not a pure theoretical person, but he tended to be more strategic and lacked data verification from on-the-spot observations.
Standing too high and unable to see the bottom of the mountain, a similar situation will not happen to just one person. Strategic mistakes caused by this have occurred many times in history.
Zhiyao decided to take "Puyang" as the level of "du".
The current "Puyang" city wall is about four miles long and three miles wide; the highest wall is nine meters, the lowest is seven meters, and the thickness is generally more than four meters; the wall is not completely straight, there are still some curves, and the overall appearance is still straight;
Even though there is a big river on the edge, the city still doesn't have a moat.
According to historical records, Duke Cheng of Wei moved the capital to "Puyang" in 629 BC. Since then, "Puyang" has become the political, economic and cultural center of Wei State.
Of course, according to the contemporary historical records of Zhiyao, the capital of Wei State was moved from "Chaoge" to "Diqiu". Later historians have repeatedly verified and verified. In view of the loss of too many documents, according to the discovered city ruins,
Near "Puyang", "Puyang" is used more frequently than "Diqiu".
"Have there been any wars in Puyang in history?" Zhiyao thought to himself.
There must have been many wars that took place in "Puyang", and three of them are particularly memorable. They were the battle between the Yellow Emperor and Chi You in ancient times, a contest between Xiang Liang and Zhang Han at the end of the Qin Dynasty, and a fight between Cao Cao and Lu Bu at the end of the Eastern Han Dynasty.
.
In those battles, there was no record of "Puyang" being attacked by water.
What Zhiyao can remember is Xiang Liang and Zhang Han, Cao Cao and Lu Bu. As for the battle between Huang Di and Chi You, it belongs to ancient times and is regarded more as a mythical story.
The number of unprecedented battles that took place in "Puyang" is too few, which to some extent can also prove that "Puyang" is not an important military location.
There are many strategic locations for military strategists, and great wars will inevitably break out again and again in their long history.
The reason is that the local area has too much strategic value. If it is a battleground, it will definitely be fought over, and repeated wars are inevitable.
Zhiyao and Sun Wu walked around the surrounding area and discussed a lot, including which places must have cities as barriers to the capital, and the construction of cities can also serve as strongholds to build up local agriculture.
"If Puyang is the capital, connecting the two sides of the Taiwan Strait is the top priority." Sun Wu said.
Now there is only one bridge spanning both sides of the river, which is on the "Mengjin" side of the Zhou royal family's territory.
Zhiyao looked at the surging river water sweeping eastward. Standing on the south bank, the north bank was already blurry. The width of the river was at least 800 meters, and she felt a little worried.
Big rivers, the most exaggerated width can reach 20 kilometers, it is located in Dacheji, Changtan County, Henan; the narrowest one is only more than ten meters, located in Yehu Gorge.
In the next few days, Zhiyao personally inspected the south bank of the river near "Puyang". After careful inspection, he found that the narrowest width was more than 400 meters, especially because it was far away from "Puyang" and was not suitable for construction.
The location of the bridge.
In order to solve the bridge problem, Zhiyao had to summon Gongshu Ban and Dou Shuo.
"Yao wants to build a bridge across the river." Zhiyao said straight to the point.
Gongshu Ban and Dou Shuo looked at each other. Neither of them spoke, quietly waiting for Zhi Yao's next words.
Zhiyao went on to say: "It is necessary for Dou to explore the riverbed near Puyang, find a slightly higher section of the riverbed, fill it with large ships with stones to make an island, and tilt the sand to form an island. How to prevent the river water from blocking it, and even
During the rainy season, the rivers flood both banks, relying on the many Dou clans."
The only one Zhishi who specializes in water conservancy engineering is Dou. If Zhiyao doesn't rely on them, who else can he rely on?
Dou Shuo was completely immersed in Zhiyao's talk about using big boats to carry big stones to fill the river. The more he thought about it, the more he felt that this was a historically unprecedented method and was definitely feasible.
Of course, every water conservancy project has the characteristics of affecting the whole body. A sudden increase in the riverbed somewhere will not have an impact on the height of the riverbed. It does require rational and rigorous consideration and design.
Dou Shuo said with confidence: "It is easy to explore the river bed. I just don't know where Zongzi wants to build a bridge and what kind of bridge he wants to build?"
What kind of bridge should be built? It can be like the one at Mengjin, with boulders and wood structures. However, the wider the river, the more difficult it will be to build.
Zhiyao said: "The river is filled with huge rocks to make an island, and mud is accumulated on the island to form an island. Do not use it too wide, more than 20 meters long and wide is enough. The distance between each island needs to be determined by the length of the Dou family and the Gongshu family.
.At that time, we may lay stones, erect timber, or use iron ropes for support. Is that okay?”
This method is a fool-like operation. The main reason is that it cannot be compared to modern times. When building bridges on river sections, there is a lot of technical support to build bridge piers in the river.
It is precisely because of the need to build artificial islands that Zhiyao's previous request was made, that is, the emergence of artificial islands should not lead to the possibility of flooding on both sides of the strait, otherwise it would be a man-made natural disaster.
Dou Shuo said with a thoughtful expression: "Perhaps we can build the dam in Cao first in the summer, so that the river water can flow into the north section, and the water level in the south section will drop, making it easier to fill with rocks?"
Now the river has two outlets to the sea, which were roughly divided into two in modern Huaxian County. This is a new situation that emerged after the Yellow River changed its course. It once caused Wei and Qi to suffer from floods, and the impact was for more than two hundred years.
After a long time, the place that was flooded by the river slowly recovered later in the late Warring States Period.
Zhiyao just puts forward an idea. Whether it is feasible or not requires technical personnel to discuss it. At least it needs to build a relevant model based on the actual situation, and only through repeated trials can a generally reliable conclusion be drawn.
Model? In fact, it is like a more sophisticated thing than a sandbox, but it is more sophisticated than a sandbox used for military purposes.
In addition, the sand table was not originally created by military strategists. It was actually created by a family engaged in water conservancy projects. Later, it was used many times in wars, and many people mistakenly thought that it was the military strategists who first created the sand table.
Zhiyao needs to wait for Dou and Gongshu to discuss a feasible plan, including which river section, how much labor is expected to be needed, and how long it will take.
"I can make up for the fact that 'Zhiyao' is the first operation to build large ships in the Central Plains!" Zhiyao felt something strange in her heart.
What? Zhiyao was actually the first person to build a large ship in the Central Plains? This is indeed the case!
In the original history, Zhiyao used the Wu envoy to go to Jin and built a large ship that could accommodate more than 2,000 people. He planned to take advantage of the opportunity of sending the Wu envoy to pass through the river to sneak attack on Wei.
The envoys of the State of Wu saw through Zhiyao's plan and were unwilling to take the Jin ship. As a result, Zhiyao had a plan but was unable to implement it, and the Wei State escaped disaster.
How big would a large ship be that could carry more than 2,000 people? Historical data only mentioned large ships, but did not record relevant data about large ships.
Of course, the Zhi family currently has shipbuilding factories. One is located in "Xiyang" southeast of "Ye" city, and the other is near "Shuzhou" near Yan State.
So far, the largest ship built by the Zhi family is 24 meters long and 16 meters wide. The shape is divided into two categories. The first one is similar to the lucky boats of the Song Dynasty, and the second one is more traditional in Zhuxia.
Building ships all have a keel.
There are two different styles of boats, and the design concepts are both from Zhiyao. Among them, the Lou boat is a flat-bottomed boat and the Fu boat is a sharp-bottomed boat.
The factory for building building ships is located in "Xiyang", while the construction site of Fuzhou ships is in "Shuzhou".
By the way, "Shuzhou" is a brand new administrative unit. There are actually not many Lishu there. It is geographically located near the outlet of the northern section of the river. It is precisely because of this that the construction of Fuchuan was arranged there.
.
In the current time period, Zhiyao pays more attention to Lou Chuan.
After all, running to the sea is not the main thing. The demand for ships in the inland river sections is more important. How can we do things regardless of the importance?
Three months later, Gongshu Ban and Dou Shuo came together to ask for Zhiyao. It seemed that the mission given to them had been concluded.
"How is it?" Zhiyao waited for three months without urging her once. In fact, she was already impatient with the wait.
Gongshu Ban and Dou Shuo looked at each other, and the former said: "The Gongshu family and the Dou family think it is feasible to fill in rocks to build an island."
Hearing the answer, Zhiyao breathed a sigh of relief.
Dou Shuo lowered his head and said: "If you are building a dam to block water, you need to pay attention to the year. In addition, if you are filling in rocks to build an island, you may need to build dikes on both sides to prevent accidents."
Zhiyao, who had been mentally prepared, breathed a sigh of relief and frowned again.
Building dams on both sides of the river? You can imagine how large the project will be and how much labor will be used.
Dou Shuo paused, and then continued: "Shuo thinks, maybe we can build one or two islands first, and then survey the water level for confirmation?"
The width of the river exceeds 600 meters. In fact, the impact of building an island with a diameter of 20 meters will not be too great. The difficult part is to what extent artificial construction of islands will cause changes to the river bed. If the base underneath does not cover an area of
Large, the impact will naturally be minimal.
Zhiyao didn't dare to joke about Dahe. Once there was a problem with Dahe, it would definitely be a big trouble that would cause long-lasting harm.
"If we continue to explore further, it won't be a problem if we are a little far away from Puyang." Zhiyao made a compromise.
The bridge must be built, and adopting the plan with the lowest difficulty and the least consequences will definitely be the first priority.
After receiving the signal, Gongshu Ban and Dou Shuo became less stressed and left after talking about what they needed to talk about.
Zhiyao thought about it for a long time and couldn't remember who built the bridge over the river in Hebei Province.
Zhiyao is wrong here. Historically, in the late Spring and Autumn Period, a cross-river bridge was built in a place called Jijin. Later, although the bridge was damaged, it was repaired and used repeatedly until the Sui and Tang Dynasties. The name also changed from "Jijin" at the beginning.
Jin" was renamed "Suxukou" in the Warring States Period, and "Baimajin" in the Western Han Dynasty. Later, the name "Jijin" was used in the Western Jin Dynasty for a few years, and in the Eastern Jin Dynasty it was changed to "Baimajin". The name was changed again and again.
.
Zhiyao had been worried for less than a month this time. After the conditions were relaxed, good news came from the Gongshu family and the Dou family.
It’s not a coincidence, it’s just the geographical location and environment. After the two families explored the area that still has no name, that is, the Jijin River section, they brought good news to Zhiyao!
