Chapter 937: Let Liu Qingjing also sigh

A day later, the railway passed the acceptance.

But Gao Fangping, who was persecuted and delusional, was still not at ease, and specially invited the Empress Dowager Liu Qingjing and several elite craftsmen from Beijing County to accompany him and walk along the Beijing Railway.

Every place and every embankment is inspected, so let's think it's a hike.

Of course, Gao Fangping understands the principle of the railway, but whenever he encounters a place where the roadbed is relatively densely spaced, Gao Fangping has to stop and deliberately ask: "Then why is the previous section, the roadbed is fifty centimeters apart, but here it is thirty-five centimeters apart?" ”

In the face of his deliberate inquiry, Liu Qingjing felt very presence, and said: "Xiao Gao Xianggong doesn't know, this is the theoretical point about pressure, after the initial geological survey, although the selected road sections are relatively qualified, there is no need for special heavy pressure." However, there are still some differences in the hardness of the soil layer between the road and the road. The road sections with loose subgrade horizontal strips are relatively hard places, and an interval of 50 centimeters is enough, but now these relatively soft soil places, in order to increase the focus point and reduce the pressure on the local land, not only the subgrade beam arrangement needs to be more dense. ”

"Oh." Gao Fangping touched his chin and nodded, pretending to be stupid.

He also asked: "In order to catch up with the construction period, we built in a hurry, a bit like a face project, this is the first railway designed by the Royal Academy, and the tonnage of our temporary simple rollers is not enough, I am careful that in the rainy season, this railway will still have an embarrassing situation?" ”

Empress Dowager Liu smiled proudly: "Xianggong doesn't need to worry, this is measured and designed." It is indeed a face-saving project, but according to the fact that your first line is only a special train of less than 100 tons, a speed of less than 20 knots, and the load and speed will increase by one layer every year in the future, then the mourning family is sure that this railway can withstand it in ten years, and there is no need to repeat the construction excessively. ”

In this way, Gao Fangping is really relieved. This railway is limited to the current technology and equipment, and then added the suspicion of rushing work, which is too different from later generations, and it is indeed a bit like a tofu scum project. However, it is still necessary to respect the science model proposed by Gao Fangping himself, which has made enough margins, measured and designed. Gao Fangping also believes that such a railway will definitely not be able to support a 1,000-ton special train and run at a speed of 40 knots, but the bearing capacity of the current large bearings and the thrust-to-weight ratio of the backward turbines of the engineering institute will be enough for this railway within 15 years.

Fifteen years later, it was enough to redesign it according to the technology and trends of the time, and that was not a big price. The biggest problem in railway construction lies in the ownership of the right of way, in fact, the cost of man-hours and materials is not too expensive......

Jingxian County is on the periphery of Bianjing, and it happens that this large-scale industrial base is next to the Ring Railway, and they have their own railroad tracks to connect with the Ring Railway.

Therefore, after the arrival of the ship from Jiangzhou, a group of specially dispatched craftsmen from the engineering institute began to assemble the turbine and locomotive in the large workshop in Jingxian.

In the large-scale open workshop, Gao Fangping was watching the whole process, and at the same time, he was also psychologically booed.

The equipment and tools here are already comprehensive, and the internal coordination of the team is also very orderly and skilled, and everything seems to be professional.

Back then, this Jingxian County was still a place mainly used for raising pigs, and a small number of craftsmen were also quite grassroots inside, doing things roughly, almost one did not accept the other, and each was busy with their own personal heroism.

All this is like a world away from each other.

At the last moment, everything was ready, and the primitive and bulky, stupid locomotive had been assembled.

Then the chief engineer of the trip came over and saluted: "Gao Xiang, the front of the car is assembled, and I request an ignition test." ”

Gao Fangping was disappointed for a while, this ghost thing is really not a thing compared to the bullet-like high-speed rail locomotive in his memory. However, it is a milestone-like thing, and it is the family foundation accumulated by the Great Song Dynasty for many years.

So Gao Fangping also said with some excitement: "Approve the ignition test." ”

Bang...... Boom Boom Boom......

After the ignition of the fire, the smoke was billowing and the sound was shocking, as if the demons in Journey to the West were born, and everyone was choked and ran around.

Gao Fangping ran the fastest, ran out of the big workshop to take a few breaths of air, and then saw that the entire large workshop was "smoking from seven holes".

Oh - Oh -

In the blink of an eye, after the powerful air horn roared, and in the booming and rumbling sound, the stupid and thick locomotive really drove out of the workshop with three carriages and along the tracks.

Niu Gao looked black and did not slip in the autumn and stood on the locomotive Golden Rooster Independence, looking very excited.

An engineer stuck his head out of the humble train room and cursed Niu Gao: Your saliva will corrupt this big guy, don't drool anymore.

Eventually, the train left Jingxian and followed the Beijing Ring Railway. Gao Fangping wanted to get in the car, but was forcibly dragged away by a group of people, saying that it was unsafe and he couldn't get in the car for the time being. After the commissioning is completed, confirm that the turbine is stable.

So Gao Fangping, who has never run, also ran like a marathon this time, chasing the train farther behind.

The entire railway around Beijing is under martial law by the forbidden army, and it is an exaggeration to say that there is a post in ten steps, but every five hundred steps there are two forbidden troops standing guard to guard the railway that is about to cut the ribbon for the emperor.

These big-headed soldiers also felt shocked, looking at the stupid big stupid bear with black smoke, running really slowly, but it looked muscular and strong, and they also felt unaware.

Yes, the current 2.1 belt wheel is very frustrated, Tao Zhiming and they are not wrong, the thrust-to-weight ratio is still too low, and the degree of thermal efficiency is still very large. So the train is very slow now, and it is possible to catch up with running.

In the case of such a low thrust-to-weight ratio, the self-weight of the unit greatly squeezes the load of this train.

After running for a while, the maximum speed of this train will look like thirteen knots.

However, it is now an empty train, and it is a certain challenge to achieve the first phase goal of a special train, three carriages, and a load of 30 tons required by Gao Fangping.

For this reason, the Jiangnan Engineering Institute specially designed a new gearbox system, but it is also stupid and coarse, and the backward original gearbox further loses efficiency, but the advantage is that it can be exchanged for load by sacrificing speed through the principle of leverage.

After the new tuning of the turbine by the Engineering Institute, it can temporarily maintain this fixed power output for a long time. However, the shortcoming is in the gearbox, the current process technology, even if relying on new materials, the gearbox is also designed to be very grassroots, and not durable, will be scrapped soon.

Without gearbox, direct output, it will retain a part of the power without loss, so that the thermal efficiency in the relative environment is improved, the weight will be smaller, and because of the simplicity of the structure, it can reduce mechanical failure and prolong the service life, but the fatal thing is that it is impossible to achieve the load requirement of 30 tons of high square level, which can not be done at all.

In other words, this is a targeted face-saving project for the emperor to see. In fact, the 30-ton transportation mode is not commercially available and mature.

The current gearbox is specially made, and it was forged by Han Yihui and countless elite craftsmen who tried their best and spent a lot of resources. The only task is: to fool the emperor.

However, this "labor and money" is worth it, and the start of any business is like this, starting from scratch, burning money, and tackling tough problems. Now it is necessary to fool the emperor in order to lay the groundwork for the school of science in one fell swoop, and then it will spread and multiply like a virus. Damn, it's not just Taoist priests who can play this set, Gao Fangping is better than they can play.

In the future, with the progress of various technical processes, the gradual rationalization of design principles, and the rise of material science, 30 tons is just the beginning, and the 2,000-ton special train will eventually connect the east, west, north and south at a speed of 35 knots. That's the real Imperial Chariot.

It's night again, and Jingxian is brightly lit.

Countless black and non-slippery participating members lined up neatly, and said in unison: "The special train test and acceptance have been completed, please instruct the senior minister." ”

Gao Fangping stood on the turned off locomotive and said: "Everyone has worked hard, and everyone involved has worked hard. ”

"In the service of the rise of the empire!" All the guys are stupid and righteous, and they are very neat, whether they are the science party of the engineering academy or the sergeants.

Gao Fangping was speechless, Xiao Li Gang was really awesome, he had been a general judge in Jiangzhou for two years, and he had actually trained them like this.

Yes, this must be Xiao Li Gang, Shi Jingjie's kid has a different style, just his words, he won't train people like this.

Cold, Uncle Zhang pretended to be forced into this big workshop at night. He carried his hands behind his back, tilted his head, and wore sunglasses.

Yes, Jiangzhou has developed and produced sunglasses, which can be regarded as a niche luxury, and there is not much use. However, this time, the team brought some and gave them to the royal family and several powerful ministers, and Lao Zhang also had a pair. So he wore it stupidly, and now it was clearly night, and he wore it too, and refused to take it off.

As a result, he tripped and almost hit the street, Gao Fangping went over to take it off, "Xianggong, this thing is not used like this, I will help you keep it when you take it off." ”

"You don't understand, this is something new, the old man is testing its magic, you are careless, don't break it." Uncle Zhang opened Gao Fangping's hand and did not allow anyone to touch his sunglasses.

The rest of the people saluted Lao Zhang one after another.

The light here is not bright, at night, people are clearly standing in the east, the old Zhang Abing's shape waved to the west and said: "Busy with you, don't worry about me, I can't sleep, I heard that there is a boom and boom here, come and take a look, and investigate the disturbance of the people in Jingxian County." ”

"......" The subordinates who stood on the east side waiting for the praise were all embarrassed.

Finally, accompanied by Liang Hongying, she helped Lao Zhang to walk around and point out the introduction.

Although he has not seen the load of this thing with his own eyes, he has only heard about the weight of this thing called a train, and has tested it three times today, and there are no moths, Lao Zhang already knows that there will be a lot of gambling plates that will be looted this time.

On this issue, Lao Zhang really didn't believe that dozens of tons of things could run on those two thin rails without falling into the mud. When Lao Zhang inspected the surrounding counties in an ox cart, he often encountered the problem of getting stuck in the mud.

Thinking about it, Uncle Zhang pointed to Niu Gao in front of him and said: "Xiao Gao, two days later, the old man and the courtiers will look at you with wide eyes, anyway, you bought these lands from Kaifeng Mansion with money, and these materials are also your money, if something happens, you are the one who loses money, and you are the one who loses face." If it succeeds, let's discuss how to divide the benefits, don't be unconvinced, although the materials and land are yours, but the workers are the old man's soldiers, you can't rely on this, at least the imperial court participates in the construction of shares. ”

Sister Liang had a headache for a while, and reminded in a low voice: "Xianggong, this guy in front is Niu Gao." ”

"I know he's a cow." Lao Zhang wore sunglasses and turned his head around and said, "Xiao Gao, where are you hiding?" ”

Gao Fangping walked over to the side and said: "Now just wait to win, wait for popularity, it's easy to talk about popularity, because no matter how you talk about it, there are benefits." ”

"That's it." Lao Zhang planned to leave.

Gao Fangping said embarrassedly: "Why don't you take off your sunglasses first and wear them again?" ”

"You don't understand, this thing is new. It's not called sunglasses, it's called sunglasses. Lao Zhang left under the escort of his entourage......
