Chapter 22 Bridge Building Plan Shaanxi Raiders

After listening to Yan Boju's words, Zhang Zhimu glanced at Lu Bingyi, who was directing his disciples to hang drawings in front, and said, "What to do, let's listen to Mr. Lu!" ”

Lu Bingyi turned around and said, "Wait a minute, it'll be right away." ”

After hanging up the drawings, Lu Bingyi cleared his throat and said, "Okay, then I'll tell me how the Fenhe Bridge was built, right?" In fact, the scheme of this bridge was suggested by Mr. Zhang, and we only designed it in detail according to Mr. Zhang's suggestion. The idea of this plan was simply incredible, and when I saw a few sketches that Li Yunhe brought me, I was simply stunned. But when I heard that it was the plan given by Mr. Zhang, I understood. Hehe! It's not the first time that Mr. Zhang has given us such a surprise. ”

Lu Bingyi combined with the drawings to introduce how to use 50 steel pipe piles to make the bridge pier foundation, and then build cement piers on it, use double round arches to cross the bridge piers with 50 meters apart, and use box girders to make the general technical concept of the bridge deck.

Needless to say, the expressions of these leaders of Yaogang were shocked. It's something they've never heard of.

"Have you figured out how to build it?" Chen Yufeng was a little uneasy, "Let's just say that the steel round arch that spans fifty meters how do you get the bridge pier, and how do you think about how to get the steel pipe pile?" Also, how high is this bridge deck from the water, and when our warships enter and exit, the mast shadow does not affect? ”

"Mr. Chen's questions are very good, and these are what I will talk about below. According to calculations, this round steel arch can be completely welded on the shore and transported by ship under the piers. We built a tower crane on each of the built piers, and the tower cranes on the two piers hung the two ends of the round steel arch respectively. This allows it to be hoisted onto the piers. Of course, there are some specific technical issues that need to be solved. We can install a drilling rig on the boat, drill holes in the bedrock of the river bottom, and then pile the steel pipes into it, and then fix it with cement. The height of this bridge deck is like this, we finished driving the steel piles at the normal water level, and the height of the steel pipes was not high above the water, so we used a steel box and 50 steel piles to weld together, and built a 15-meter-high bridge pier on top of the steel box. In order to reduce weight, T-shaped piers were adopted. This round steel arch has a sagittal span ratio (ratio of the height of the round arch to the span) of a quarter. Then the height of the round steel arch is 12.5 meters. Our deck passes through the middle of the arch, at the bottom of the bridge five meters from the top of the pier. In this way, when the box is one meter high, the bottom of the bridge deck should be twenty-one meters from the water. Our average sailboat can pass normally. If there is a heavy flood, if the ship's mast cannot be passed, it is necessary to avoid (sound) the mast (put down the mast). ”

At this point, the people below began to discuss.

Someone said: "Ordinary ships more than 20 meters high are fine, and ships with higher masts can't get here." ”

"Even if the water grows longer, the average boat will be fine."

Ouyang He was also interested in this bridge, "How is your bridge deck connected to the round arch?" ”

"As you can see from the map, we have three piers in the Fen River, and the other two piers are on the shore. There are two round arches with a span of 50 meters and two round arches with a span of 30 meters. Our deck passes five meters from the piers, which is 7.25 meters from the top of the 50-meter dome and 2.5 meters from the 30-metre dome. Our principle is that the bridge deck under the round arch is hung with steel cables, and the top above the round arch. In order to be able to better hold on, we also build a small round arch between the two round arches to support the two round arches. The bridge deck is topped with small round arches. In addition to the four round arch bridges, we need to make the approach bridge a little longer. The approach bridges are solved by cement piers with a span of 10 meters and cement bridges. Lu Bingyi seemed to be very well prepared, and he introduced the main part of the bridge in one go.

"Do we have such a long steel pipe for the pillars now?" Yan Xing asked.

Li Yunhe replied for Lu Bingyi: "We have an eight-meter-long seamless steel pipe that can be welded and used. The steel pipe of the round arch is too thick, and it needs to be welded with steel plates rolled into cylinders, and then welded into round arches in sections. ”

Lu Bingyi also said: "We have added a place to Mr. Zhang's plan. It is to add a round steel pipe to the 50-meter round arch and the bridge deck flush between the round arches. As we all know, the round arch bridge is to break down gravity into gravity and horizontal thrust, both of which act on the piers. We counteract this horizontal thrust with a transversely drawn steel tube, which reduces the horizontal shear force on the pier. The 30-meter span of the round arch also has a horizontal tension rib. ”

Yan Boju suddenly remembered a question, "Have you ever thought that the upper reaches of the Fen River have to put wooden rafts downstream every year, and if such wooden rafts come down, won't your bridge piers be knocked down all at once?" ”

Everyone is talking about it again, because what Yan Boju said is the truth, and there are many people who live by releasing the Fen River.

"There is no other way, you have to choose between building a bridge and putting a row. If the bridge is built, the upstream of the bridge cannot be discharged. Lu Bingyi said firmly, "As for the other collisions, we have considered it, and we are adding a few piles in front of the fifty steel piles in the direction of the water." These piles are non-load-bearing, triangular in shape, and are designed to block the impact of upstream objects. ”

Lu Chengxiang, who had not spoken, said: "I see, what Mr. Zhang said is okay. No matter how much money you spend, you have to do it. However, after the bridge is built, you will have to charge money for crossing the bridge. One copper plate for one person, two for a horse, and three for a cart. Not much, right? ”

Lu Chengxiang's deliberately greedy appearance amused everyone.

Zhang Zhimu said: "Mr. Lu is right, there should be a toll for crossing the bridge. However, we can only collect one-way fees, and the cost of building the bridge will never be recovered, but the fee collected will be enough to maintain the bridge. ”

Another key project of this kiln gang was unanimously approved without any objection, and Duan Jingzhong was instructed to be the general responsibility of the highway and bridge construction committee, and Lu Qi was the chief commander of the bridge construction. Lu Qi was required to take office immediately after the kiln cement was put into production and delivered. Start preparing for construction now. It was imperative to convert a water drill vessel with two tugboats, as well as several tower cranes.

After the meeting, everyone left, Chen Yufeng and Ouyang He didn't leave, and they also let Zhang Zhimu and Li Yunhe stay in the conference room.

Chen Yufeng said: "Zhimu! If you arrange for something like building a bridge, you can leave it to them. Let's discuss the matter of Shaanxi. ”

"Huh! Shaanxi has you and Mr. Ouyang, what do I care? Zhang Zhimu said with a smile.

"There's a little thing, Yunhe is here, you can arrange it." Chen Yufeng said: "We used to use heavy fire oil bombs before, and that thing worked very well against targets such as enemy camps. Are we going to make some heavy fire and oil shells with mortars, 120 heavy mortars, 130 guns? ”

"Leave this to me." Li Yunhe said, "I'll just arrange it." ”

"Actually, we have something better now, and it is better to change the fire oil to gasoline." Zhang Zhimu said.

"That's right! What Mr. Zhang said was that the gasoline was even worse. Li Yunhe said affirmatively.

"You can also use gasoline to make more terrifying weapons," Zhang Zhimu said very cautiously, "If we make it into coagulation, it is a lethal weapon, as long as napalm is stained on the body, we will definitely die, and we will die very miserably." It is not to deal with the great evil enemy, and it should never be used lightly. ”

"What's so powerful?" Li Yunhe asked, and Chen Yufeng and Ouyang He also looked at Zhang Zhimu.

"If you dissolve rubber in gasoline to form gelatinous gasoline, it will collapse into a person's body, and it will burn people's bones until they are burned, and if they don't burn to death immediately, they will also be poisoned to death, and if white phosphorus is added to it, it will be even worse. That thing could never be extinguished, because the white phosphorus spontaneously ignited when it saw the air and ignited the gasoline. If our aluminum can be produced in large quantities, the combustion temperature will be higher if we add aluminum powder. When Zhang Zhimu said it, he thought that this thing would be used again when dealing with little Japan in the future!

Listening to Zhang Zhimu's words, Chen Yufeng and Ouyang He looked at each other. Ouyang He said: "Mr. Zhang, we may not use it, but we will develop it." With this thing, the deterrent effect is even greater. ”

"That's it," Li Yunhe said, "I'll go back and let them develop both ***, and then we'll see what the effect is." ”

"This thing must be kept strictly confidential. We call this kind of thing a kind of bullet, we just know it. Zhang Zhimu said.

Chen Yufeng said to Ouyang He: "Then let's talk about the big thing!" ”

Ouyang He nodded and said to Zhang Zhimu: "According to the trouble that General Ningde went to the south bank of the Yellow River some time ago, we found that Li Zicheng will not have many men and horses north of the Great Wall of Shaanxi, and the army there is unstable and does not have much fighting spirit. We just want to revise the strategic arrangement and speed up the pace of the military settlement of Shaanxi. ”

Zhang Zhimu nodded and said, "Yes, I don't think Li Zicheng wants a place either, to be honest, it doesn't make much sense for them to send out a lot of people to guard the Mu Us Desert." The soldiers sent out also knew that as long as we attacked, they would be meat on the cutting board. There won't be much combat power. ”

Ouyang He said: "So, we don't want to waste much time with them north of the Great Wall. As long as we solve the place south of the Great Wall, there will naturally be solved. ”

Zhang Zhimu smiled and said, "Let's talk about your specific opinions!" ”

"Originally, our plan was to attack in the north and south at the same time to solve the Shaanxi problem. Now we want to march into Shaanxi in three ways. One way or the south road, through Tongguan, we can enter Weinan by land and water at the same time, straight to Xi'an; On the east road, we are going to cross the Yellow River from the meanders of the river and directly enter the Great Wall, regardless of the Great Wall, and march south. Take Yulin and then run to Yansui, Yan'an, Qingyang, Pingliang, and Guyuan; After marching along the Yellow River in the west to capture Ningxia (Yinchuan), it continued to attack and advance along the Yellow River, passing through Lingzhou, Ningxia Zhong, and Jinglu to Lanzhou and the confluence of the South Road, and after solving all the Dashun troops in Shaanxi, they would advance westward as appropriate to completely solve the western problem. ”

"I agree with the idea. However, after we divide our troops, we will not have enough soldiers. We can borrow troops from Zhou Yuji's general army, and they will send people to guard the various passes of the Great Wall, which is more than 1,000 kilometers long. We just give them food. After we have solved the target in Shanxi, we will go back and reorganize Zhou Yuji's army. Now that the imperial court no longer pays them food and wages, we will directly take over their soldiers and horses. Don't let it be sinned again. Zhang Zhimu suggested.

"That's a good idea, but what if the emperor asks us for someone?" Ouyang He asked.

"Pretending to be stupid, we don't admit it." Zhang Zhimu said, "Arrange a place for Zhou Zongbing to lead troops in a separate place, and don't let people know." Hi! The emperor is a smart man, and if he dares not to give Zhou Yuji food and salary, he knows that we will definitely take over. The emperor knew that even if he gave Zhou Yuji food and salary, he couldn't use them. So everyone just knows it. ”

"Huh! Mr. Zhang counted the emperor in his heart. Ouyang He said.

"Who are you going to send to lead the troops?" Zhang Zhimu asked.

"The South Road is still personally carried by me and Mr. Chen, because this way, we need to control the speed of the march, too fast, too slow; If Mr. Zhang does not replace General Ningde, the West Road will be led by him. He is familiar with the situation in the northwest, so let Li Kui be his deputy. Once he met Sun Chuanting and them, Li Kui was a person who didn't rub sand in his eyes. It can also start to work; We haven't decided on the east road yet, whether to send Liu Yun or Zhao Jinli. There is still time for this, so let's think about it again. Ouyang He replied.

"The question is, who is responsible for all the Baotou lines?" Chen Yufeng said, "I think when we do it, the Mongols and the Manchus will definitely make a move." I'm going to be prepared. So far, we have been able to solve Shaanxi militarily very quickly, and there is not much suspense. It doesn't hurt to just think things through a little bit more comprehensively. ”

"We also found that there is another advantage to solving Shaanxi, that is, Shaanxi is relatively closed. We solve it here, without scruples about other places. We can solve the Shaanxi problem and train the team and our generals. The next time we march into Henan, it is likely that it will not be Henan, and the entire Central Plains needs to be solved together. At that time, it was necessary to divide the army into several routes, and each road needed to have generals who could solve problems independently. A very important task this time is to train and inspect our generals. Ouyang He said.

"Mr. Ouyang thinks long-term. When we get to that point, we can send Li Mao and Li Yan, two Li Gongzi, to participate in military operations with you, and they will also share some of the burden for you. Otherwise, it's all up to you and Uncle Chen, it's too tired. Zhang Zhimu said.

"That's great." Chen Yufeng said, "It is time for them to start a role in the military." ”

"Now each of them is very important. Hehe! Ouyang He smiled after speaking.

"Also, I suddenly remembered that the wind and sand in the west are particularly strong, and we must equip each officer and soldier with a goggles, which should not only breathe the wind and breathe, but also block the wind and sand, and it is best to bring brown and white lenses that can be switched. Masks were also distributed to the soldiers. Zhang Zhimu said.

"This soldier is simply so blessed, it looks like going to war, I think it is like a groom who is going to pick up the bride." Chen Yufeng said with a smile, "Now everyone has given them two pairs of knitted gloves. Look at this soldier, it's like an uncle. ”

"In the future, they will shed blood and sacrifice, and we will try our best to treat them well, and if the conditions are good, we can greatly reduce non-combat attrition." Zhang Zhimu said.

It's not yet May, and everyone is looking forward to the fact that the kiln cement has not yet been put into production, and Qingfengzi and their phosphate fertilizer and ammonium sulfate have been put into production respectively. Lu Bingyi and Lu Chengxiang were so happy that they immediately sent a lot of fertilizer to Dongshengzhou, Baotou, and at the same time, Lu Bingyi and their agricultural technicians also followed.

Seeing Zhang Zhimu, Lu Chengxiang said happily: "Mr. Zhang is good this time, the yield in the fertilizer field can be at least 30% more." ”

Lu Bingyi said: "Mr. Zhang, our fertilizer production line is continuously produced, and the output is not small. This year, we can allocate some fertilizer throughout Shanxi. But we don't have many technicians who understand fertilizers, so let's study it. Otherwise, the fertilizer will be distributed, and it will not be used well in various places. ”

"Yes," Zhang Zhimu patted his head and said, "Call Yan Xing, Li Mao, and Old Dong's Qiu family and ask them to come over." ”

"What are they doing here?" Lu Bingyi asked.

"Hey, hey!" Lu Chengxiang understood, "Zhang always wants to borrow troops, right?" ”

"Yes!" Zhang Zhimu gave a thumbs up and said, "I can't hide anything from Mr. Lu." ”

After these people came, Zhang Zhimu told them about the mass production of fertilizer. They also know that fertilizer is a very magical thing, and that crops can produce more food with it. But they don't know what the matter is to bring them here.

Zhang Zhimu said: "You are now training a lot of cadres, and now you are arranging a specific job for them as a practical course. ”

Seeing that they didn't understand, he said with a smile: "There are certain skills in the use of this fertilizer, and when to use it, how much to use, and how to use it are very interesting." Most of our technicians have gone to the reclamation sites outside the gates. We need a large number of people to go to all parts of Shanxi to promote the use of chemical fertilizer technology, we Mr. Zhang said, this year's fertilizer will be distributed to farmers around the country for free. It is also a lot of work for these fertilizers to be distributed to various places, and it is more necessary to guide farmers to use chemical fertilizers. So we want to train these training officials on the technology of using chemical fertilizers first. Let them work as technicians to guide farmers in various areas. In the future, when they become officials in various places, they also need to understand the use of chemical fertilizers. ”

Li Yan clapped his hands and said, "Great, I don't even know what to tell them again." We don't say anything else, Mr. Lu, you send someone to give them a course on chemical fertilizer, and then we arrange practical courses for them, and they are all assigned to various places to guide the use of chemical fertilizer, which is also an exercise for them. ”

Yan Xing also said: "This is really a good thing, if this is the case, we will produce a lot more grain this year than last year." ”

"You all have a lot to do, so my old man will be in charge of this matter! I also accumulate some virtue for the people of Shanxi. Qiu Laodong said.

"Huh! Old Uncle Qiu, I invited you to come over just to ask you to come forward to do this. Because you are familiar with the situation in Shanxi, you can study the distribution plan according to our fertilizer production, fertilizer production progress, and the distribution of crops grown in various places. Zhang Zhimu said, "I haven't opened my mouth yet, your old man has asked for war first." ”

"Hey, hey! This is the benefit of being old, knowing what you are suitable for? Qiu Laodong said, "But after all, your officials have to listen to my arrangement." ”

Li Yan hurriedly said, "Don't worry, no one dares to disobey you." As long as you're not satisfied, don't even think about scheduling work. But old man, this is a worrying job, you must pay attention to your body. ”

"My body, you ordinary young people may not be comparable, besides, I still have a group of people in that office. It's time for them to do something, too. ”

Following the production of chemical fertilizers, Qingfengzi brought two more good news to Zhang Zhimu. and sulfonamides were mass-produced.
