Once, a wire was broken, causing the line to be paralyzed for several days, causing damage to public property.
Then the person who secretly cut the wires was seriously injured himself.
The vehicle manufacturer was so angry that he reported the case.
In the final result of the court hearing, not only was the vehicle factory not ordered to pay compensation, but the family members were also required to pay compensation and the injured person was sent to jail.
From then on, no one dared to make trouble again.
When Hunan Province was trial-operating electric locomotives, Li Wenjun asked Yang Shouzhuo to expand the high-speed railway to the northernmost part of Guangdong Province.
Yang Shouzhuo refused without thinking.
This line is already very busy and cannot be stopped to increase speed, so the Shinkansen can only be built.
Northern Guangdong is full of mountains.
Anyone who builds roads knows that bridges and tunnels are the most expensive.
Especially in tunnels, if the geological conditions are not good, there will be no sound at all when money is thrown into it.
And this area happens to be a typical Danxia landform, full of caves and underground rivers.
When building the existing north-south line in Suicheng, the Guangxi Bureau suffered a lot.
A hole collapsed and an entire construction team was buried inside.
Yang Shouzhuo's heart still trembles when he mentions it now.
More than a hundred people died just like this...
Li Wenjun smiled like a wolf grandma: "Don't be afraid, I am here. Besides, technology has advanced so much now, and I am so much more advanced than others, so what are you afraid of?"
Yang Shouzhuo narrowed his eyes and looked at him: "Tell me, what are your plans?"
Li Wenjun took out a set of drawings: "You are the only one who dares to take a look at such a confidential thing. This is what I am developing and producing. It is an artifact for digging holes."
Yang Shouzhuo looked suspicious and took a look.
A large cylinder with fan-like blades on the front.
Like a steel earthworm with a wide mouth, it eats rocks from the front, transports them out from the back, and then keeps crawling forward.
Yang Shouzhuo narrowed his eyes and asked, "Are you sure you haven't watched too many science fiction movies?"
Li Wenjun sneered: "Illiterate. The United States has been using this machine a hundred years ago. Its scientific name is a tunnel boring machine. The subway to be built in Haicheng next year is in cooperation with France. Why should it be built jointly with France? Because they have shields. It has an electric locomotive and tunnel construction experience.”
Yang Shouzhuo looked at the picture carefully and remained silent.
When he heard what Li Wenjun said, he remembered that this was the case.
He snorted: "This thing is quite troublesome. Why don't you just buy it from Germany, America and France?"
Li Wenjun said: "Haha, why the Qing Dynasty fell behind is because of this kind of comprador thinking. Think about chips, think about fuel engines, airplanes, and all kinds of countless technologies. If you just want to save trouble and buy from others, in the future everything will be taken care of by others. It’s stuck. They have gone through three generations to reach the fourth generation. We have just started, and if we don’t find a way to catch up, it will take many more years.”
Yang Shouzhuo said: "It's easy to talk, but it's hard to actually build a machine that can run safely and reach the sky. It's absolutely impossible to achieve it based on your cartoon-like concept. Even if I just read your cartoon, All involve disciplines, such as mechanics, optics, machinery, civil engineering, electrical, hydraulics, sensing, materials and other disciplines. And each subject must be strong to be successful."
Li Wenjun hurriedly put a high hat on him and said: "As expected, it was Comrade Yang Shouzhuo who saw the essence of the problem right away. However, the industrial categories you mentioned are all my strengths. In fact," Researcher Wenjun ', we have been researching it for more than half a year. It's just that they don't know what it is. We have made more than 20 types of blades and more than a dozen types of hydraulic equipment. We will assemble the first ground machine next month Dragon One is coming."
There are actually only three key points in the manufacturing of a shield machine, the power part, the transmission device and the blade.
Li Wenjun and others can even make aircraft engines, so there is no difficulty in the first two items.
The blades should be equipped with blades of different materials and shapes according to the different softness and hardness of the rock.
When the geology is hard rock, a hob is generally used. When the geology is soft rock, a toothed cutter is generally used. If you are in the middle of the two, you can choose a cutter for work.
So it’s mainly a question of materials and metal processing.
Li Wenjun asked the machinery factory, with the cooperation of the Materials Research Institute, to make more than ten types of blades, which should be strong when used and easy to replace.
The Machinery Factory had been building armored vehicles before and had gained a lot of prestige. Now that it had received a new task, it was the first of its kind in the country. They were very excited and went all out as if they were full of blood.
Yang Shouzhuo naturally knew Li Wenjun's urine properties, and if he dared to tell the specific time, he would be 100% sure.
He frowned: "You don't want to engage in such a big battle just to test the electric locomotive."
Li Wenjun smiled: "That's definitely not the case. You also know that the next five-year plan mentions accelerating infrastructure construction. I can tell you responsibly that the next thirty years will be the golden thirty years for our country's infrastructure. This shield The market for institutions is very large, beyond your imagination.”
In his memory, in 1996, a TBM was purchased from Germany for the Qinling Tunnel, a choke point project on the Xikang Railway, at a cost of 300 million yuan per unit. The 300 million yuan spent at that time was enough to complete the railway from Suicheng to Shaoguan.
The key point is that they are still unwilling to pay attention to you, and they will not come to check if there is a problem. It is obvious that they are deliberately blocking China's neck.
Not to mention 1996, Haicheng's subway will soon use this technology next year.
In the future, cities will become more and more prosperous, and roads, subways, railways, and municipal pipelines will all go underground and tunnels will be dug.
You can't always be controlled by others.
He asked Li Wenjun: "Are you sure it's safe and won't collapse?!"
Li Wenjun said: "Don't worry, we have repaired the tunnel wall while digging. How can it collapse? Besides, there is basically no need to enter the front end. It is all electric equipment. Just install a camera in the front."
Yang Shouzhuo: "Okay, Xiu. Where does the money come from?"
Li Wenjun: “Guangdong Province’s infrastructure funds.”
Yang Shouzhuo narrowed his eyes and stared at him: "You are quite good at calculations."
Li Wenjun coughed dryly: "I will also sponsor some. But you have to buy a shield machine from me."
Yang Shouzhuo pursed his lips: The left hand gave money to the right hand again.
This bastard is as slippery as a loach.
With the support of Li Wenjun, Yang Shouzhuo proposed to the railway authorities and Guangdong Province to electrify the main north-south railway lines in Guangdong Province.
The Guangdong Province thought about the speed of the section from Suicheng to Huadu, and quickly approved it and started designing it.
Li Wenjun participated in the entire design process. After all, the shield machine must be designed and manufactured according to the size of the tunnel.
After the drawings were finalized, he went back and asked the factory to start making the first shield machine.
After all the preparations for railway construction were completed and construction was still underway, when it was time to excavate the first tunnel, Li Wenjun's super-large truck transported the shield machine to the site.
