Chapter Seventy-Four: Baotou Iron and Steel Plant, Hequ Yellow River Bridge

As soon as the train starts, the dining car is bustling. Everyone didn't want to stay in the sleeper car, so they all went to the dining car to drink tea and chat.

Lu Chengxiang was drinking tea with Zhang Zhimu, and when he saw Li Dong and Liu Bao coming over, he beckoned them to come and sit. Li Dong and Liu Baoxue sat down and began to drink tea, and Lu Chengxiang spoke, "I said, you two, can't you press more on the steel basin and steel bowl?" You can't press it out, and our enamel factory can't produce it. Now Quanzhou and Guangzhou have telegraphed that these enamel products are as many as there are. ”

As soon as Li Dong heard Lu Chengxiang's words, he said: "We have been working there all the time, and the stamping dies have broken down several times." ”

"Oops! Let me tell you, this enamel product was produced in the previous period and was used by our army. Each soldier has a basin and a water tank, you say that's how much. We have just given our school all the students again. Now it's time for you to expand your production capacity, and it's time for us to make a lot of money. ”

"The expansion of production will have to wait until the end of the year." Li Dong said, "We have to wait for the 100-megawatt generator in Niutoushan to generate electricity at the end of the year. ”

"In my opinion, even if the unit generates electricity at the end of the year, it is still not enough." Lu Bingyi squeezed over with a water cup, "Mr. Zhang, I've always wanted to say." Our electricity and steel need to be a little ahead of our time. ”

"Yes! We used to think that naturalization was quite advanced, thinking that this 100 megawatts of electricity would not work for a while. Zhang Zhimu said, "If only the Hutuo River reservoir could generate electricity." ”

"Huh! That's early. Lu Bingyi said, "We should prepare for the construction of another unit in Niutoushan." ”

"Good! After a while, Li Di came over and settled the matter. Zhang Zhimu said to Li Dong and Liu Baoxue, "When you arrive in Baotou and determine the minerals, you will immediately set the location of the steel mill." Then, the power plant and the cement plant were put on the ground first. Otherwise, everything will not be transported from the kiln. ”

"This time, several of Mr. Lu's disciples also went with us, just to set these plans in advance, and those who are capable will do it first." Li Dong said.

"Yes, this time I asked them to first determine the railway line from Baotou to Baiyunkuang. It would be convenient to repair this section of the railway and do something else. Lu Bingyi interjected.

"Baotou is full of coal, and when your power plant is planned, you have to set aside a few more places to build 100 megawatt units. The cement plant should also set aside a few more kiln locations. Zhang Zhimu said, "In the future, the electricity and cement produced by the hair will not only be used for our own use, but also for support in Ordos." Our Qinzhi Road will pass through the desert, and we will build an underground water diversion pipeline with cement pipes on both sides of the road. With water, you can plant trees and grass on both sides of the road. That's a lot of cement. ”

Liu Baoxue said: "The potential to build a steel mill in Baotou is also very large, as long as there is enough ore, the conditions there are much better than the current smelting field." We can directly build a large blast furnace from the beginning, and the blast furnace molten iron can be continuously made into steel, and the steel ingots can be rolled continuously. Everything can be laid out from scratch. I think at least the steel mill there is several times the size of the smelting yard. ”

Lu Chengxiang and the others were all stunned when they heard Liu Baoxue say this. In their opinion, the smelting field is already huge. But Zhang Zhimu said, "Changchang Liu, you are too petty. The size of the smelting plant is at least dozens of times larger. There's going to be a steel city there, so be bold in your plans. We can start little by little, but if we want to build the whole country in the future, we still need a few large steel enterprises like Baotou. You are now exploring a way to build a large steel enterprise. In this construction, you should make use of the lessons and experiences you have summed up in the smelting plant. The starting point should be high. ”

Everyone was stunned by Zhang Zhimu's courage, and even Lu Bingyi didn't expect Zhang Zhimu to set such high requirements for Baotou Iron and Steel Plant. However, Zhang Zhimu's words made Li Dong and Liu Baoxue a little enthusiastic, they knew that what they were going to build would be the largest steel plant in the world, so big that they couldn't imagine it now.

Suddenly, Liu Baoxue asked: "Mr. Zhang, you said that those molybdenum ores were shipped, what should I do?" I don't think that thing is any different from graphite? ”

"Huh! You treat them with nitric acid, and there is no reaction in graphite, and there is a reaction in molybdenum ore. Zhang Zhimu said, "The most important thing about molybdenum ore is sulfide, you can treat it into oxide and reduce it with carbon or hydrogen just like zinc." But if you want to make steel, just use oxide. The refined molybdenum can be made into molybdenum wire as a tool for cutting and processing. ”

"What are the benefits of molybdenum steel?" Li Dong asked.

"He's much more thermal. There are also permanent magnets that can be made. Zhang Zhimu said, "In this matter, after you return to the kiln, you can go to Master Qingfengzi and them." They need to know a lot about this. In the future, with molybdenum steel, the pipeline valves used in our high-temperature boilers can be made of molybdenum steel, which is safer. ”

After lunch in the dining car, everyone went back to their private rooms to rest. Zhang Zhimu looked at the workers outside the window for a while, who were working on the double line of the railway, and was about to go back to the private room to rest, when Xiao Hongyu finished eating and came over with a teacup and sat down. Zhang Zhimu couldn't leave all of a sudden, so he hurriedly asked, "You didn't go back to rest?" ”

"Why do you want to drive me away?" Xiao Hongyu was not polite.

"Where are the words," Zhang Zhimu said, "why do you have a ** smell when you speak?" ”

"Huh!" When Xiao Hongyu heard Zhang Zhimu's words, she almost spilled the water in the cup with a smile, "This is a ** taste?" ”

"Isn't it?" Zhang Zhimu said.

"Hey! I've always wanted to ask you, why have you been avoiding me lately? Xiao Hongyu put down the teacup and looked at Zhang Zhimu.

"Hiding from you? Am I afraid that you will eat me? Zhang Zhimu said, "I also want to ask you, why do you want to tell others what I told you?" ”

"What do you say? How so? Xiao Hongyu was a little anxious, but quickly stabilized.

"Didn't you say that Huang Yukun said that I didn't agree to marry you because I watched him and Yang Yulin save me?" Zhang Zhimu finally said what he had always wanted to say.

"Huh!" Xiao Hongyu laughed and said, "It turns out that you are a big hero, and you still have such a little careful eye?" I said you always avoid me, just for this? Hehe! Little Hongyu's smile trembled.

Zhang Zhimu was a little angry, and said in his heart that you don't know that you are wrong, and it seems to be reasonable, "Have you laughed enough?" Zhang Zhimu's words were also a little cold.

"Look at you, are you really angry? What like a big man. Xiao Hongyu saw that Zhang Zhimu was really angry, so she quickly suppressed her smile and said, "When my sister-in-law came to me to talk about it, I didn't think that my sister-in-law was an outsider, so I said it." It's nothing, right? ”

"What is Huang Yukun talking to you about?" Zhang Zhimu actually asked knowingly.

"Say she agrees to marry me!" When she said this, Xiao Hongyu didn't dare to look up this time.

"Humph! It's weird," Zhang Zhimu said deliberately, "She married you from a woman's family?" ”

"Don't play stupid!" Little Hongyu was a little dissatisfied.

"Why am I pretending to be stupid? Your business has nothing to do with me, and I don't know. Zhang Zhimu felt very uncomfortable, and they would give it to him without going through him. made Zhang Zhimu feel very funny.

"You! Not like a man at all? Little Ruby was a little angry.

"Don't talk nonsense, okay?" Zhang Zhimu doesn't want to say that this is something now.

"Good!" Xiao Hongyu immediately changed her face and said, "You know, where is the crisis in our kiln? ”

Listening to Xiao Hongyu's words, Zhang Zhimu was shocked, "Crisis? ”

"Our kiln is like a building now, but it is all supported by your pillars. People's good days depend on you alone. If something goes wrong with you, it's all gone. It is faster than the collapse of the Ming Dynasty. Xiao Hongyu didn't look up, and said softly while pulling the tea in the teacup.

"You're right, we don't have a complete system in place to get us on track. However, the law that Li Yan is engaged in now is to prepare for this. Zhang Zhimu said, "Now we can't replace the laws of the Ming Dynasty." In that case, it would be a rebellion. ”

"Actually, in the emperor's place, you are already a thief. It's just that the emperor needs the silver of the kiln, and he also needs to kill thieves for the kiln people. Maybe you're already a bigger thief in their eyes. ”

"Huh!" Zhang Zhimu said, "At this point, Emperor Chongzhen and I both know this and take what we need." But the initiative is in our hands. ”

Zhang Zhimu didn't expect Xiao Hongyu to see the problem so profoundly. However, Zhang Zhimu also felt that this little Hongyu was a little too smart, not only was she smart to see these things, but more importantly, she knew what she was willing to listen to. Fang Cai didn't have an appetite for that topic, she didn't look like a little woman, she didn't get angry right away, but directly changed the topic here. It seems that this little woman is definitely not ordinary.

"Alas! How's the preparation for the movie you're going to make? Zhang Zhimu diverted the topic.

Xiao Hongyu also knew that Zhang Zhimu didn't want to talk about it, so she replied, "We have a few plans." I also tried to shoot some films with the machine, and I thought the effect was good. If you don't go to Xi'an, you're ready to start filming now. ”

"When this movie is finished, you will not only be a famous actor, but also a movie star." Zhang Zhimu said, "At that time, everyone in the world could see your demeanor." ”

"When the time comes, just don't annoy people!" Xiao Hongyu was obviously still a little resentful, and got up and left after speaking.

When the train arrived at the meander, the meander suddenly became lively.

Here, the Yellow River flows around the river from the east, west and south, meandering, as its name suggests. The county seat of Hequ is the "ancient Saixiong Pass" that guarded the frontier in the past dynasties. During the stable years, this is the land and water wharf that the Jin merchants who come from the south to the north must pass through. The camel gang was loaded with furs from the Western Regions and Inner Mongolia and went to the Central Plains; The caravan, loaded with fine silk tea from the south, went to the northwest. The small county town of Hequ is often full of merchants and warehouses. However, due to the repeated wars, it has been a long time since there was a beautiful scenery here. Zhang Zhimu and his entourage had dozens of glass carriages, and when they arrived at Hequ, they quickly caused a sensation in Hequ. The magistrate here in Hequ heard that Zhang Zhimu from the kiln gang had arrived, and he also rushed over. Although this place is not yet under the control of the kiln gang people. But Zhou Yuji, who was in charge of them, went out to fight with the Yaogang people, and he was a county magistrate, so he naturally knew what to do when Zhang Zhimu arrived. When he arrived at the train station, the magistrate had to invite Zhang Zhimu to dinner. Zhang Zhimu refused, he knew that life here was not very good now, although the train was here, and the situation was getting better. Villagers can also earn some silver by participating in the construction of railways and roads. But this is just the beginning.

The Yaogang people have just built an inn by the ferry here, and they have just built a branch here. Lu Chengxiang went directly to that branch regardless of anything else. Zhang Zhimu, Yan Boju, Lu Bingyi, Yan Xing and others took Lu Qi, Li Dong, and Liu Baoxue to the bank of the Yellow River.

Lu Bingyi pointed to the Yellow River and said: "Li Yunhe, they sent someone to take a brief probe, the water flow here is faster, and the sediment at the bottom of the river is not thick, at most it is more than one meter thick. Most are less than a meter, that is, the river is too wide. ”

Yan Boju said beside him: "Zhimu, it's not easy for you to build a bridge here. It's going to take a lot of piers. The water is deep and rapid, and it is not possible to drill and drive piles. ”

Zhang Zhimu smiled, and after asking Lu Qi and the others to come over, he pointed to the river and said, "Let's build a real Yellow River bridge here." You see, I am more worried than building bridges at the bottom of the river, because the banks are too high. If my bridge is built too low, when I cross the river, I have to go down from both banks to the bridge deck to cross the river, and then go up to the riverbank. It takes a lot of effort. However, the bridge is too high, and the cost of building the bridge will be too high, so we need to choose a suitable bridge deck height. Pick a balance point. ”

Lu Qi stood by the river and looked at the Yellow River, and said, "Mr. Zhang, you still tell me how we can build bridge piers in the Yellow River, and then we can choose how high the bridge is according to the situation." ”

Zhang Zhimu reached out and picked up a branch on the ground, drew it on the ground, and said: "You see, it is very difficult for us to fix a boat that can be drilled with a straight anchor here like in the Fen River, because the sediment is too shallow and the straight anchor cannot be fixed at all. The water flow is too fast, and the position of the hole cannot be fixed if it is drilled too much. We can use caissons to build bridge piers. ”

"Caissons?" No one has heard of it.

"Yes caissons." Zhang Zhimu said, "There are many kinds of caissons. The simplest caisson is used here. We poured cement on the riverbank into a boxy box with no bottom at the top and bottom. Then it is taken by boat to the place where the pier is to be built, and it is slowly lowered to the bottom of the river by crane. The lower port of this cement caisson has a cutting edge, and when it is lowered, it will sink into the sediment at the bottom of the river by its own weight. At this time, we continue to dig out the sediment in the caisson, especially the sediment near the caisson wall. The caisson will fall all the way to the bedrock at the bottom of the river. Be careful not to let the caisson crooked. If necessary, drill several holes outside the caisson and fix them with stakes. When the caisson is stabilized, the caisson will not be affected by the water flow and will have a stable environment. We can drill holes in the caissons. We can use a big drill bit to drill a hole of 150 millimeters, and later we can drill a bigger hole, drill a dozen holes ten meters deep in the bedrock, and then put the bundled and welded steel bars into the hole, and then pour sand cement into the hole. Wait for the cement to solidify. We then poured half a meter of cement on the bottom of the caisson. Remember to remove as much sediment as possible from the bottom of the caisson when pouring water into the caisson. This requires a diver to go into the water to do it. Wait until the cement at the bottom of the caisson has set. We can pump the water in the caisson clean, lay steel bars in the caisson, weld the steel bars to the steel bars on the pile, and then pour them layer by layer. Pour until it is level with the top of the caisson. At this time, the caisson and the cement poured inside are a cushion cap. Its function is to distribute the pressure of the entire pier to all the piles. The cap is ready, and the rest is to pour hollow cement piers with cement on the cap. As for the bridge above, whether you want to use arch beams or steel trusses, it depends on your wishes. ”

After listening to Zhang Zhimu, Lu Qi couldn't help but say: "Wonderful, it's just wonderful." In this way, there will not be much problem in building this Yellow River bridge. ”

"Huh!" Zhang Zhimu smiled again and said: "There is a problem that you didn't expect that a large amount of cement is poured continuously, and it is simply not available by manually mixing cement." ”

"Yes, yes!" Lu Qi nodded and said, "There is such a problem on the Fenhe River, and the amount of cement used here is incomparable over there." This problem will be more prominent. ”

"Mr. Lu, after you go back, you have to discuss it with Li Yunhe. You're going to build a cement mixer. It doesn't matter if it's electric or diesel-powered. In the future, more cement mixers will be needed on the Hutuo River. Zhang Zhimu said, "There is another question, that is, after a large amount of cement is mixed, how do you transport it to the bridge pier?" Therefore, it is also necessary to develop a high-pressure cement pump and use a pipeline to transport it. Of course, it can also be conveyed by conveyor belt if possible. ”

Lu Qi said: "Okay, I'll organize and study these when I go back." It's not too hard. ”

"The hard part is the high-pressure conveying." Zhang Zhimu knew that this matter was not as simple as he thought.

Lu Bingyi asked: "Mr. Zhang, can we also build bridge piers like this in Tongguan in the future?" ”

"Huh! The situation at the bottom of the river there is not at all clear, and whether it is suitable or not depends on the specific situation. Zhang Zhimu said.

"It seems that there is really a way to build a bridge here!" Yan Boju said.

"In that case, this place will be connected to Shaanxi and Ordos." Yan Xing said, "Is it possible to drive the train over?" ”

"We don't have the experience of building a bridge, let's build a passing one first." Zhang Zhimu said, "When we have experience, we must build a bridge to cross the train." ”

It was still early in the morning, so Zhang Zhimu and others went to the railway site and the shipyard on the wharf to visit the workers there. When he returned to the inn in the evening, Zhang Zhimu invited everyone to a drink. Because tomorrow several groups of people will have to move separately. He also knew that everyone was willing to come out with him, otherwise they would go to different places separately, and they might not necessarily have to come to this meander. Everyone left the kiln, and they all let go of a lot of things here, and they could drink with confidence.

Early the next morning, Lu Qi and the others went all the way to Baode. Li Dong, Liu Baoxue, and Li Dong took a boat all the way to Baotou. Zhang Zhimu and his brigade crossed the Yellow River through a pontoon bridge and arrived in Shaanxi.
