Chapter 1025 Visiting Xingang County
"Blast the mountain?!"
"What's a tunnel?"
She Xin and You Fu were shocked by Luo Chong's words. They didn't expect the leader to come up with this method.
"A tunnel is a man-made cave that is dug from one side of the mountain to the other side, connecting the two ends of the mountain and opening a road. Isn't there a saying that goes "build a road when you encounter a mountain, build a bridge when you encounter a river?" Digging a tunnel is also a way to open a road." Seeing the two people's surprised and puzzled expressions, Luo Chong explained to them.
"Build a road when you encounter a mountain, build a bridge when you
encounter a river?" She Xin and You Fu both said that they had never heard of it at all, and they didn't know who the leader heard this from, but it did make sense. Since there is no road, then just open a road out. However, digging through the mountain? Isn't this a huge amount of work?
So I heard You Fu say it again.
"Chief, it's not impossible to dig caves, but we don't know how many caves we need to dig to open up the entire railway line. This project is too large, difficult, and time-consuming. If we build the road in this way, the total length can indeed be shortened, but the time may be several times longer."
"No, didn't I just say that we can just use explosives to blow it up. First, send people to survey the terrain and find the most suitable location, and then dig from both ends towards the middle.
"When digging a tunnel, first use an air hammer to drill holes in the stone wall, then fill those holes with explosives, and then pull the fuse. When the time comes, detonate them all at once, and you can blow off a layer of the stone wall at a time. After the middle is hollowed out, use a pneumatic hammer to manually trim the stone wall of the tunnel. It only takes a while to repair it, and then use steel bars to make an arch support, support it with a wooden mold, and pour concrete into it to reinforce the tunnel. At the same time, you can also use concrete to smooth the stone wall of the tunnel. "
Hearing You Fu's concerns, Luo Chong once again talked about the construction method. She Xin and You Fu were speechless after hearing it. It turned out that the leader had even thought of the construction method, and he talked about it as if he had seen how to dig a tunnel.
However, the two of them were no longer surprised. They knew that the leader was a god. Anyway, as long as Luo Chong said it, there was basically nothing that could not be done. There were some things that they had never seen, and the leader could also talk about them clearly, as if he had seen them with his own eyes.
"Since the leader has thought of a way, there will be no problem. However, digging a tunnel should be a technical job. I wonder who should be sent to be responsible for it?" You Fu nodded, indicating that he agreed with the leader's idea, and then asked again about the candidates for digging the tunnel.
"We can mobilize from all over. We can gather some people from the cross-sea bridge construction site in Qiongzhou. The people there have very rich experience in the use of explosives. The stones they use to build the bridge are all blasted from the mountains on the shore. As for the use of reinforced concrete, they also have the most experience.
"In addition, we will mobilize some people from the coal mines in Dongxin County. The coal mines they dig are actually similar to tunnels, but this time they have changed from digging coal seams to digging rocks. The technical difference is not that big.
"Finally, we will mobilize some people from Xingang County who are good at using machinery. I will see if I can ask them to rush to build a large rock drill. This should increase the progress of the project." Luo Chong talked about his arrangements again.
The rock drill is actually the bucket on the mechanical arm of the crawler excavator removed, and then replaced with a large air hammer as thick as a calf. This thing is very convenient for digging rocks on the top of the tunnel. Otherwise, if you want to dig the top of the tunnel, you have to build a scaffold for people to go up and dig. That is not only unsafe, but also slow.
Modern rock drills are basically the same thing, but they are specially used for digging tunnels. They are professional types, not those that are temporarily modified from excavators. The most obvious difference is that professional rock drills generally have more than three mechanical arms on the body, and some can be equipped with five or six mechanical arms. Like a spider, baring its teeth and claws.
As for the shield machine that specializes in drilling holes, that thing can only be used to drill holes underground. It digs soil layers, not rocks. It is generally only used to dig underground tunnels or subway tunnels, and does not have the function of digging rocks.
Even in modern times, the combination of chisels and explosives is still used to dig mountain tunnels. The only difference is that the chisels have become large-scale machinery, and the power of explosives is also very considerable, but the essence has not changed.
She Xin and You Fu both nodded again, and You Fu continued, "In this case, let me take the task of exploration. I have led people through there once, and I am more familiar with the situation there."
Luo Chong agreed and instructed again, "For the matter of digging tunnels, you must survey the local geological conditions. If it is a dirt mountain, just flatten it and dig out a road. There should be no steep slopes on both sides to prevent landslides when it rains heavily, blocking the road and ground collapse. That would be even worse, so you must pay attention to the geology.
"If it is a rocky mountain, you also have to pay attention to the terrain. Never dig a tunnel on the side of the center of gravity of the mountain, otherwise you will hollow out the bottom and the top may collapse. And when planning the route, you can't just say that we can dig a tunnel and then really dig directly from the middle of the mountain. Don't dig if you can avoid digging. If there is no other third method besides taking a detour and digging a tunnel, then you can consider how to dig the tunnel.
"When digging a tunnel, try to find the weak point of the mountain, a position closer to the edge, and don't dig in the middle.
"Also, you must pay attention to the water source and springs on the mountain. At the same time, you must bring more water pumps when digging tunnels. If the mountain leaks water when digging the tunnel, use a water pump to pump it out in time. You must also do a good job of waterproofing afterwards, so as not to turn the tunnel into a water curtain cave.
"Another way is to build a bridge. Some places with water, places where you need to cross the river, or some canyons in the mountains, if you have to take a long detour, then build a bridge over the canyon.
"So, the planning of this route is very important. You must do it seriously and responsibly. In principle, there are four requirements. First, shorten the route as much as possible. Second, reduce the cost as much as possible. Third, shorten the construction period as much as possible. Fourth, the above three must be carried out under the condition of ensuring the safety of construction and future use."
Luo Chong said some precautions for digging tunnels and surveying terrain. You Fu was also listening carefully there. After listening for a while, when he felt that he could not remember, he quickly took out a pen and paper and started to take notes.
After You Fu finished taking notes, he asked Luo Chong some things he did not understand, and then Luo Chong began to speak.
"Okay, let's make this arrangement for the layout of the southern industry for now. Next, you two will follow me to Weishan County, and then we will call the governor of Weishan County, Lu County, and take the train to Xingang County to have a look and learn. I will also let you see the scientific research results of our Han tribe this year, especially several types of engineering machinery. Youfu, you must take a look. If you see it, you will know how simple and fast it will be to build roads in the future."
"Hehe, then I must see it." Youfu said with a smile.
"This is good, this is good. I don't know how their tractors are made, how many have been produced, and whether they can complete the production task before the New Year's Day." She Xin was also happy when he heard this. You know, the 60,000 mu experimental field in the west is his responsibility, and She Xin has long been interested in mechanized farming and large-scale planting.
Luo Chong proposed to visit Xingang County at this time, mainly to check how the research and development of the two harvesters were going. If he had a harvester, he could harvest more straw as feed or green manure. If he didn't have a harvester, he could only hire people to break the sticks, and the remaining straw would have to be burned, all wasted.
The group set out that afternoon, took a boat to the Weishan County dock, and then went ashore in Weishan County to spend the night. They had dinner with Weishan County Magistrate Lu Guangzhu, and told him to go to Xingang County for a visit and inspection tomorrow.
That night, Lu Guangzhu asked the train to Xingang County to take a message back, asking them to bring a passenger car when they came tomorrow morning, and the leader would take the train to inspect.
At five o'clock the next morning, Luo Chong and his team arrived at the train station on time. A train full of coke and limestone had stopped by the platform, spewing white gas. There was a passenger and freight carriage at the end of the train. Xingang County knew that the leader was coming, and they put an iron coal stove in the carriage for heating, and it was boiling hot water for passengers to drink.
Luo Chong and his team got on the train wearing heavy coats. After running for a whole morning, they arrived at the Xingang County train station just before lunch. As soon as they arrived, Xingang County Magistrate Dali and Institute Director Lin Fei came to greet them.
"Hello, leader." The two of them bowed and saluted.
"It's so cold, and you still come out to greet us? How come you have so much time? Don't you have to make arrangements for work?" Luo Chong asked them with a smile as soon as he got off the train.
"The chief is here. I have to come out to greet you no matter how busy I am. Besides, the work has been arranged long ago. Now all factories have implemented a double-shift system, with the old bringing up the new, and training more workers as soon as possible." Lin Fei smiled bitterly, and then introduced the situation here.
"Well, did you receive the task document issued to you yesterday? It's about the research and development task of molybdenum steel." After the group got off the car, Luo Chong followed them and said.
"I received it, but the Comprehensive Research Institute hasn't sent anyone over yet, and we don't know how to do it. We just need to wait for them to bring the experimental materials over, and we will definitely cooperate with them." Dali was responsible for this matter, so he answered it.
Luo Chong knew that this formula would not be done in a day or two, so he nodded and asked Lin Fei on the other side, "What about the research institute? Is there any progress on the harvester? How is the task of the tractor completed?"
Lin Fei's face was a little bitter when he heard this, because he didn't have any outstanding progress to show for the two things Luo Chong asked, but he couldn't help but say it when the chief asked.
"To the leader, we are now making the prototype of the first corn harvester. The progress is quite fast, but we can't experiment. There is no corn for us to experiment in this season, so we can't guarantee that it will be useful. As for the grain harvester, it is still in the stage of drawing parts drawings. Because you said there is no rush, let's make the corn harvester first.
"As for the tractor, we don't have a finished product yet. The whole factory is producing various parts according to the standards. When the parts are gathered, they will be assembled at one time."
Several people walked and talked. Lin Fei was also introducing the progress of the task, and Luo Chong nodded from time to time. When passing by the outside of the factory, he found a group of teenagers aged fourteen or fifteen tinkering with the tractor, so he said.
"Okay, let's go to dinner first. Let's talk about the tour after dinner. Also, don't wait for the parts. Assemble a few first and let the trainees train first. Now there is only one car. How can you let dozens of people learn to drive. "
Hearing this, Lin Fei turned his head and looked over there, nodded and replied, "Yes, I will arrange it in a while and see how many can be assembled with the current materials."
He also knew that what Luo Chong said was the truth. Just for this one car, dozens of people had to be trained. Even the driving school had never been so nervous when teaching driving. At least ten cars had to be made, and the six of them could use one car for training.
During lunch, everyone also talked about the vehicles that were mainly developed this year. You Fu was away all year round and didn't know the technological development of the tribe. Now he was shocked to hear that the tribe had developed a vehicle that could travel on dirt roads by itself.
Although the Han tribe had developed a steam locomotive two years ago, the train was huge and heavy, and could only travel on the railway. It did not have the ability to travel on dirt roads at all, so the land transportation of the Han tribe still mainly relied on horse-drawn carriages.
Now, not only do we have trucks that can go on dirt roads, but the locomotive can also be used to grow crops, and there are even self-harvesting machines specifically for harvesting grain. How could he not be shocked by the harvester?
When Lin Fei told him that he had developed a small hand-cranked rice transplanter, You Fu was even more excited. This was different from those tractors and harvesters. This thing was similar to a train, and they were all big. It was impossible for it to be popularized among the people. However, the hand-cranked rice transplanter was different. This thing had higher practical value and low cost. Even ordinary people could afford it. It was very suitable for popularization among the entire tribe at this stage.
As soon as he finished his meal, You Fu couldn't wait to take everyone to visit. He was really curious about these mechanical monsters. The same was true for Lu Guangzhu. Although he was the governor of Weishan County and often received news from the Xingang County Research Institute, he had only heard about it and had never seen these magical machines with his own eyes. This time, the leader finally brought him here. How could he not be interested?
