Chapter 41 Liu Chenghuang sent the king to the king of the Tongguan Bridge smoothly and smoothly made a plan

Although Li Zicheng was very reluctant, he still began to secretly organize the retreat. Li Zicheng, who has been through a hundred battles and has been through ups and downs for a long time, will not fight to the death with the kiln gang people because of his emotions, he knows how to minimize losses.

Li Zhi's original shop in Xi'an, because they used grain to help Li Zicheng in the ancient road, followed Li Zicheng to Xiangfan. Because of Li Zicheng's care, the business is getting bigger and bigger, and he has bought a lot of shops in Xiangfan. On this day, Li Zicheng sent someone to inform them that it was best to follow him to Yingtianfu or somewhere in the south of the Yangtze River. Although the specific reason was not said, they immediately promised that we would follow the king wherever he went. In fact, they understood that Li Zicheng wanted to give up Xiangfan. Although they did not receive specific instructions from their families, they knew that the kiln gang people would take Xiangfan. Take Xiangfan, then Hankou is not far away. Thinking that the people of Yaogang were about to hit the edge of the Yangtze River, the intelligence officers of the Yaogang intelligence station were all jumping up with joy. But they didn't dare to expose it yet, their work was far from over, they wanted to follow Li Zicheng and report his every move to Yaogang. The most important thing is to cooperate with ** to send the information back to the kiln.

On this day, Liu Chenghuang, who had rushed to Hanzhong first, received a strange report that someone from Xiangfan had come and asked our tugboat fleet to help them transport their goods. It was also said that the tugboat fleet could dock at the Xiangfan pier and that they guaranteed safety.

Liu Chenghuang understood that the great retreat of the Dashun army began. There are simply not enough of their ships. There are hundreds of thousands of Li Zicheng's army officials and family members here, and it is not easy to withdraw to Jiangnan. They saw that Yaogang was constantly transporting goods to Hanzhong, and most of the ships returning were empty. Because there's not much to ship out right now. So they wanted to hire ships from the kiln to transport people and goods.

Liu Chenghuang is an old man from the kiln gang, and he immediately invited someone to come. Although the visitor was a little nervous, he quickly calmed down.

Liu Chenghuang didn't bend, "Are you the one who broke into the king?" ”

The visitor was stunned, but immediately said, "Exactly!" The general has good eyesight! ”

"It's not my eyesight," Mr. Liu said, "that if you want to transport people, we can give you a ride for free." We will have ballast stones on the return journey of our empty boat, and we will send your people to Yingtianfu or Zhenjiang. But when we arrive in Xiangfan, you are responsible for the safety of our ship. ”

Liu Chenghuang's words were so shocked that he couldn't close his mouth, and hurriedly said: "This, this, I didn't expect this." Oh! Okay, I'll send someone back right away and inform the family. I'll go back with your fleet. ”

"However, I have a word for you to bring back to King Chuang." Liu Chenghuang said.

"Good! You say. ”

"We are grateful to him for sending people to protect Hanzhong so well!" Liu Chenghuang looked at the man and said.

The man nodded and asked, "That's it?" ”

"That's enough! Let's go. Our fleet will arrive at Xiangfan Pier at night and set sail before dawn, understand? Liu Chenghuang said.

"Hey! Understood, understood. The man quickly agreed and ran out. He knew that the kiln people didn't want outsiders to see them and helped them transport. However, the capacity of the fleet of kiln man's tugboats was too great. He has done a great job in getting this done. He also knew that this condition was that they would protect Xiangfan as they protected Hanzhong.

He hurriedly wrote a letter and sent two men and four horses to run towards Xiangfan with a whip.

Liu Chenghuang's arrangement makes sense. Because he knew that Li Zicheng would definitely not be very happy when he left, and if he didn't get them to leave, he would cause great damage. If a fire were set in Xiangfan City, the damage would be huge. So he seized this opportunity to stabilize Li Zicheng. In this matter, Liu Chenghuang was bold and decisive. Although it was cut first and then played, it was unanimously approved by Zhang Zhimu, Chen Yufeng, and Ouyang He.

Zhang Zhimu couldn't help but say: "This is a handsome talent!" ”

Song Xiance received this letter and hurried to see Li Zicheng. Li Zicheng, who was worried in his heart, was in a much better mood when he heard the news. Say a word: "The kiln gang people have not yet rushed to kill the meaning!" ”

"With this, the kiln people will give us time to retreat." Song Xiance said, "It's not ....."

"But what? Don't spit out. Li Zicheng frowned and didn't say.

"Our cities can't be destroyed." Song Xiance said, "When they do this, they make it very clear!" ”

"Humph! Their kiln men deceive people too much! Li Zicheng was a little angry again.

Song Xiance did not speak.

After waiting for a while, Li Zichang breathed a sigh of relief and said, "It's all burned, and we can't get anything?" The people will still scold us! ”

Song Xiance understood that Li Zicheng had figured it out, "Your Majesty, our Yingtianfu and Zhenjiang are within the range of their cannons. It would be even more terrible for them to take revenge on us. ”

"Hmm!" Li Zicheng said, "It seems that our national capital cannot be moved to Yingtianfu yet. It's not easy to live under someone else's cannon. ”

"Then Lin'an (Hangzhou)!" Song Xiance said.

"I think that's all I can do." Li Zicheng said, "If all our people are withdrawn to Jiangnan, our forces will be concentrated. It's good to do something. You tell me not to destroy the city, since we are gone, we will give a big gift to the people of Yaogang! ”

"Shall we send a message to the kiln man?" Song Xiance asked.

"Nope! Don't. Li Zicheng said, "Let's save some face for ourselves!" ”

Li Zicheng knew that the two sides had already cooperated so tacitly, one was leaving, and the other was coming to send. If you still say something else to the kiln people, it doesn't mean that you are too timid. After listening to Li Zicheng's words, Song Xiance also understood that he had almost made a low-level mistake. This is the anxiety of the past few days, which makes his mind not very clear. Since receiving the news that the Yaogang people were going to attack, Song Xiance not only persuaded Li Zicheng to make a plan to retreat as soon as possible, but also persuaded Li Zicheng to reply to the Yaogang people to buy some time to retreat. But Li Zicheng never agreed, and Song Xiance has been thinking about this matter in his heart. Today, Li Zicheng finally spoke, and he persuaded Li Zicheng to reply to the kiln people, forgetting that the situation had changed. Song Xiance, who went out, felt a little embarrassed.

Song Xiance persuaded Li Zicheng to fight to the death with the people of Yaogang when he was in Shaanxi this time, but persuaded Li Zicheng to retreat as soon as possible. It is because Shaanxi is in danger to rely on, and the Central Plains is vast, and the attacker can choose to attack in any direction. To fight the kiln people here is to find death.

After the affairs of the Southern Expedition were arranged, Zhang Zhimu didn't care about it. He is now concerned about the Tongguan Yellow River Bridge, which is the most important project of the year.

For this reason, Zhang Zhimu invited Lu Qi and Tang Jingyao back from the Hutuo River construction site, and Duan Jingzhong also invited back from the construction site to Fenglingdu. Lu Bingyi, Li Yunhe, and Lu Chengxiang participated in the Tongguan Yellow River Bridge plan demonstration meeting.

At the meeting, first of all, the drillers on the drilling ship sent by Li Yunhe made a report on the geological situation according to the drilling results.

What makes Zhang Zhimu very pleased is that their report has been done in a very detailed manner. The situation here in Tongguan is very complicated, this is the confluence of the Wei River, the Beiluo River, and the Yellow River, if the upstream river rises, it will converge here, so that the flow of water changes drastically. However, the bottom of the river is basically stable. The thickness of silt to bedrock is 14 meters (this is the data before the construction of Sanmenxia), the upper layer is 12 meters of fine sand, and the stratum has a gravel layer of 2 meters.

What Zhang Zhimu asked was that a bridge for road and railway purposes be built here.

After the hydrogeological situation was reported, Zhang Zhimu asked everyone to express their opinions.

Some people say that the method of building the Fen River Bridge is used. Some people objected, because the hydrological conditions here are complicated, and after drilling holes in the torrent, they were covered with sediment before they could wait for the reinforcement to be poured with cement.

Some people say that the method of building the river meandering bridge is used. Some objected because the sediment was too thick for the cofferdam to sink to the bedrock at the bottom of the river. Besides, we don't have such a big ship, towing a bigger cofferdam. To build a road-rail bridge, large piers are required. If the cofferdam is made upside down on the shore and transported to the position by boat in the rapids, ordinary boats cannot do it.

In fact, Zhang Zhimu has long had his own ideas, which is the method seen from TV in his previous life. It's just that I haven't done it myself, but I can tell them the way. The reason why everyone is discussing is to let everyone use their brains, and through discussion, everyone can improve.

Waiting until everyone couldn't come up with a better solution, Zhang Zhimu said: "I have an idea, let's discuss whether it is feasible?" ”

Needless to say, everyone was waiting for Zhang Zhimu to speak at the end.

"My idea was to use a cofferdam because without a cofferdam to block the rapids, all the work could not be done. However, as everyone said, it is difficult for us to build a cofferdam that is too big, and we can't move it after it is built, let alone accurately locate it. Zhang Zhimu said, "My idea is that we will build a large platform with a pontoon tank at a predetermined location, and then fix it with a straight anchor." We built a double-deck cofferdam on the platform. This double-layer cofferdam should have a bottom, so that the cofferdam can float on the surface of the water like a boat, we pour cement from the bottom little by little, when the cofferdam is high, we release water to the middle of the double-layer cofferdam, let the cofferdam sink, and then raise the cofferdam. Repeatedly release water and raise it until the cofferdam sits at the bottom of the river. Do you think this will work? ”

"Great idea!"

"Good way!"

…

After Zhang Zhimu finished speaking, everyone talked about it for a while.

However, someone soon proposed, "Mr. Zhang, before the cofferdam reaches the bottom of the river, because it does not fall to the bottom, the force of the impact of the current will be very large, what if it is washed away by the water?" ”

Someone said: "You can put some straight anchors inside the cofferdam in the direction of the cofferdam facing the water to block the cofferdam." ”

It was also said: "In front of the cofferdam, you can lay a row of pointed straight anchors and then follow these straight anchors and lay some water retaining plates, so as to reduce the direct impact of the river water on the cofferdam." ”

Another said: "Such a cofferdam must be completed before the rainy season." Stay safe. ”

Someone even raised a question, "Mr. Zhang, the sediment here is 14 meters thick, and if the cofferdam sinks to the bottom, is the cofferdam too big?" ”

After listening to everyone's opinions, Zhang Zhimu said: "I think the waterproof impact measures that everyone just mentioned are very reasonable. We can use a combination of these measures. However, a cofferdam like ours does not need to sink to the bedrock. I think it just sank into the mud and sand, three to four meters. Because the flow rate of the surrounding water will increase after the construction of the cushion cap, it is easy to wash away the surrounding sediment, and it is best to let the large bottom of the cushion cap under the sediment, so that the bridge pier is safer. But the holes we drill in the cofferdam must go to the bedrock, and the piles must be driven into the bedrock. The cofferdam is what helps us to form the cap, and our piers need to be built on the cap. The piles were driven to the bedrock and our cap stabilized. The piers were stabilized. Also since our bridge is double-decker, I recommend using a steel truss bridge. In this way, the upper and lower layers can be racked at the same time. ”

With the big plan idea, the team organized by Ouyang He's disciples is needed to design it in detail. Zhang Zhimu no longer cares.

After the meeting, Li Yunhe said to Zhang Zhimu: "This matter is over, when do you have time, let's try the delta wing, that big kite?" ”

"Are you all right?" Zhang Zhimu asked, "Is that molybdenum tube done?" ”

"That's it!" Li Yunhe said, "It's this molybdenum tube that delays time, otherwise it would have been good a long time ago." Now molybdenum steel can also be mass-produced, and in the future, we can use molybdenum steel for pipes and valves for higher temperature pressure boilers. Liu Baoxue tested them, and the high-temperature strength of molybdenum steel is much higher. ”

"Good! Have you ever thought about whether it would be better to add some molybdenum to the steel used in our gun barrels? Zhang Zhimu asked.

"That's right! In the future, if our gun barrels are also made of molybdenum steel, and then coated with a layer of chromium, the life will be longer. Li Yunhe replied.

"I see, the delta wing test flight will wait a few more days." Zhang Zhimu said, "Wait a few days, the weather will be warmer, and it will be more convenient for the test." Now it goes without saying flying, but as soon as the wind blows at the shooting range, people tremble. ”

"Alright! I'm still staring at it these days, let's get a few more cars for Uncle Chen. Li Yunhe said, "However, I am afraid that the road to the south is a problem." I'm more worried about whether the tracked truck that gave Li Wei their cannon towing can have an accident on those small bridges in the south. A tracked tractor, plus a cannon, is enough for the average small bridge. I think the small bridges in the south are barely passing through the carriages. ”

"The cars used now are for the grassland," Mr. Zhang said, "and the reliability of military cars must be high." In the future, you will have to develop front and rear four-wheel drive cars, so that the off-road performance can be better. Today's rear-wheel drive is only used on good roads in the city. In the wild, it is used barely. ”

"Okay!" Li Yunhe said, "I'm going to arrange for them to build a six-wheeled car, and when they're done, I'll let them build the four-wheel-drive car you mentioned." ”

"There are a few things that we're lagging behind." Zhang Zhimu said, "I need the person in charge of them to write a report explaining the reason." The first is that by the end of the year, the 100-megawatt generator in Niutoushan should be connected to the grid as planned. But to this day, it is still being debugged; The second is that our passenger ship should also be launched for sea trials before the end of the year, but it has not been completed; The third, the Taiyuan Bridge, was supposed to be opened to traffic by the end of the year as planned, but it was not completed; The first dock of the shipbuilding base on the fourth Zhenjiang side should have been built a long time ago, but there is no news so far, and I am still waiting for them to build a 5,000-ton ship. ”

"That's right. Li Di has made great improvements to the unit on the side of Niutou Mountain. According to the situation of the previous unit, they thought that it should be improved, and it was said that if the boiler pressure was increased a little, after the change, the same equipment could generate 20 to 30 percent more electricity. I also support them in making improvements. As for the passenger ship you mentioned, there is something new in the technology we used this time. How to coordinate and control the propellers driven by several motors is a difficult problem for everyone. Even Li Di and their people didn't use it. So take the time to try it out, but you can't help it. But as soon as they are civilized, they will be able to test the sea. There is no way for the Taiyuan Bridge to delay a little time. When the Hutuo River is tense with cement, catch up with the bridge piers on the meander side of the river to pour, and the cement must be used first. You can wait for the pavement to be laid here, but you can't wait for continuous pouring there. The dock on the other side of Zhenjiang should be about the same. Mr. Lin Zongwei has already gone there. Their ships also had to be redesigned. Lin Zongwei's son put forward some suggestions, but the father and son disagreed. Mr. Lin rushed over. However, Mr. Lin said that it will take less than a year to build a wooden boat now, because large timber can be processed with a chainsaw and electric planer. The speed is incomparable to that of the hand. I heard that Lin Gongzi wanted to build the main girder of a large ship with a mixture of steel and wood. In this way, the steam engine will be placed and fixed in the future. Because the steel can be welded with the steel. There is also the matter of the ship's mast raising and lowering, Lin Gongzi also has his own opinion. It seems that the father and son will have to quarrel for a while. ”

After listening to Li Yunhe's explanation, Zhang Zhimu Factory breathed a sigh of relief, "Ou! That's right. That's good. ”

During this time, Qingfengzi and Yangchang did not go smoothly with their integrated circuits, and the yield was too low. It doesn't seem to be as simple as imagining, just a few transistors made at the same time. However, Zhang Zhimu encouraged them that everything has a process and will not be achieved overnight. In fact, Zhang Zhimu is most anxious about these things about them. Zhang Zhimu knew that the knowledge of his previous life that he brought now had a very huge impact on this society, but this was not fundamental. If computer technology could be developed in advance, the impact would be immeasurable. In the process of social development, it will even cut corners and straighten them, reducing many detours. Because no revolution in human society has had such a huge impact as microelectronic technology. And you should have a way to get the computer out.

On this day, Zhang Zhimu was designing a video-driven circuit, and Li Zicheng came with a few people. These people are familiar to Zhang Zhimu, but he doesn't know what they do. After Zhang Zhimu invited them in, Mr. Lu introduced: "Mr. Zhang, these are the masters of our Yaogang Printing Factory. They designed the pattern of our kiln coin last time. This time, we will show you the new design plan. ”

This time, they designed a plan of 100 yuan, Wu Shi Yuan, 2 Shi Yuan, 10 Yuan, 1 Yuan, 5 Yuan, 1 Jiao, 5 Points, 2 Points, and 1 Cent. Anything under one dollar is a coin.

The patterns are all double-sided. The 100 and 50 yuan banknotes are overprinted with watermarks in four colors, and the two and 10 yuan are watermarked with three-color printing. This time, as is customary, the coins have a square hole in the middle. The obverse patterns of the four banknotes are all well-known buildings in Yaogang, 100 yuan is the front pattern of Yaogang office building, Wu Shiyuan is the front pattern of Yaogang Cultural Palace, 20 yuan is the front pattern of Yaogang Library, and 10 yuan is the front pattern of Yaogang Museum. The back patterns are all figures, and 100 yuan is the side pattern of four portraits of workers, peasants, soldiers and scholars proposed by Zhang Zhimu; Wu Shiyuan is a side pattern of college students, middle school students, and elementary school students; The second circle is a pattern of a driver driving a tractor; Ten dollars is a pattern of a driver driving a car.

The design of the coin features Chinese characters on the obverse and Arabic numerals on the reverse. In addition, the coin pattern design is very fine, there are three Chinese characters of kiln gang coins, and only one time pressed into a mold. Zhang Zhimu of the one yuan suggested that it should be made of nickel-containing alloy steel, so that the one-yuan one seems to have some weight, the pentagonal one is made of aluminum-copper alloy with high copper content, and the others are made of silicon-aluminum alloy.

It can be seen that these people have spent a lot of effort. After reading the pattern, I listened to their report again. They also point out where the anti-counterfeiting mark is.

Zhang Zhimu said: "It can be seen that you are taking this work very seriously. I can't fault the slightest. Thank you so much. ”

These people were relieved to hear Zhang Zhimu say this.

Zhang Zhimu said: "I want to ask for the opinions of other leaders on these patterns, if everyone has no opinions." Everyone is about to make plates and start production. But this matter is to be kept secret, I don't need to say more. ”

After talking about the kiln gang coin, Zhang Zhimu chatted with them about printing technology again. These people are all in the printing business. The printing technology they are engaged in is already relatively advanced today. Zhang Zhimu focused on discussing color printing with them. These people are well aware of the color overprinting and screen overprinting techniques of wood boards. But Zhang Zhimu knew that their understanding of color was still based on experience. They know how to mix red, yellow and blue into various colors, but theoretically they don't understand it at all.

Zhang Zhimu learned this knowledge when he was learning the principle of color TV in school. In particular, when I was researching data image processing, I worked this aspect. I just didn't expect it to work now. It seems that everywhere is knowledge, and I don't know when it will be useful.

Zhang Zhimu introduced to them that the three primary colors in optics are red, green and blue, and these three colors can be combined into any color, and the three colors are synthesized together, which is white. This is known as the "additive method". However, this method cannot be used in printing, and "subtractive color method" is required in printing. The three primary colors of the "subtractive color method" are magenta, yellow, and cyan. In order to avoid confusion with the concept of "primary colors", they are called "three inverse colors" or "three complementary colors". The complementary color of red is cyan, the complementary color of green is magenta, and the complementary color of blue is yellow. We can print in three colors: red, yellow and blue. However, it is difficult to strictly control the three-color ratio to become true black, so it is necessary to add black to become four-color printing. However, in order to improve the color expression, we can also add light magenta and light cyan to make six colors.

When Zhang Zhimu told them, these people immediately took out a pen and paper to record it.

Zhang Zhimu knew that this was not enough, and he would have to tell them how to make color separation plates in the future.

Finally, Zhang Zhimu said: "I am just having some brief discussions with you today. Later, when we have time, we will prepare to tell you more about this printing. ”

After listening to Zhang Zhimu's words, Lu Chengxiang interjected: "You have seen it." I said it when I gave you the task. In front of our Mr. Zhang, you have to show all your skills. Nothing can fool Mr. Zhang. With what Mr. Zhang just said, you can go back and ponder it. ”

How could these people not nod their heads and say yes.

Zhang Zhimu hurriedly said: "Mr. Lu, don't say that. I chatted with you for a while, and I gained a lot of knowledge. There is a specialization in the art industry, and no one is omnipotent. However, let's talk about it when I schedule some time! ”

Zhang Zhimu showed the pattern they designed to Chen Yufeng, Ouyang He and others, but no one put forward any opinions. The plan for the new coin is settled.
