My Daming New Empire

When Zhu Zhanji rode a steed and galloped towards the scene of the car accident, they couldn't hold back their curiosity and ran to follow.

Xiamaqiao Farm is now the most famous neighborhood in the outer city of Yingtianfu besides Chang'anfang and Taipingfang.

The earliest underground passage in Daming, the earliest concrete road in Daming, and the earliest greening scenic spot, the residential area and the research institute area with strict uniform design form a large garden area.

Because of the existence of the research institute, the Xiamaqiao Farm is not open to the public. Even if outsiders can see this beautiful land from the north road of the farm, they cannot enter.

In the south of the farm, there is a tributary of the Qinhuai River, which just separates the farm from the Temple of Heaven and Earth in the south.

When building the farm, Zhu Zhanji strictly prohibited the construction of houses within 100 meters from the river, and built a park within 200 meters north and south of the river.

The innermost part of the park is dominated by weeping willows, the middle is a large area of ​​various flowers, inlaid with various bonsai-like landscape trees, and the outermost part is the evergreen pines and cypresses transplanted from the mountain.

Although this park is not wide, it is very long. From the Zhengyang Gate of the Imperial City to the east, it stretches for about three kilometers, forming the largest scenic spot in the southeast of Yingtianfu.

After it was built, it became the favorite outing place for the people of Yingtianfu.Including those whorehouses and painting boats, they also like to come here to do business when the river is busy.

However, because of the blockade by Habayashi Guard, they cannot set foot on the north bank. Otherwise, they will be imprisoned for at least a month, and then they will be punished after they are found out to be not spies.If it were a spy, no one would hear from him again.

The newly built railway surrounds the residential area, and the southern line is between the park and the residential area.As an experimental railway, although it is only three kilometers, it is enough.

The scene of the car accident is not far from the departure point, on the east side of the Northern Line, where it turns south.

Now, apart from the fact that the front of the car has not turned over, two of the four carriages behind have turned over, and two more have also derailed.

But fortunately, because the car did not have a roof, when the car overturned, although some people were severely thrown, and even a few unlucky ones were seriously injured, most of them were fine.

When Zhu Zhanji arrived, they had already started to save themselves, and moved the injured people aside to wait for treatment.

Many of the spectators were imperial physicians from the hospital. They immediately treated the people on the spot, and then sent people to pull the carriage to take the seriously injured to the hospital for treatment.

After all the injured people had been transported away, Zhu Zhanji and a group of engineers started on-site surveys, wanting to know why the car overturned.

Car accidents were not uncommon even in the Ming Dynasty.

Since livestock was used as power and the main means of transportation, various car accidents have emerged in an endless stream from ancient times to the present.

There are dozens or even hundreds of car accidents caused by crazy livestock and car accidents caused by the wrong car every year in Yingtianfu.

But there has never been a car accident as serious as this one.

The cause of the accident was quickly found out. When the train was turning, because the rails were made of wood, they couldn't bear such a heavy force, so they couldn't fix the vehicle and the wheels fell off.

"Your Highness, the wooden rails cannot be effectively fixed when the vehicle's center of gravity shifts due to insufficient correction rate. But...if all the rails are replaced with iron ones, the cost will be too high."

Zhu Zhanji looked at the torn stubble on the rail, shook his head and said, "No, just use the wooden rail."

He is well aware of the development history of the railway. The tracks were made of wood at the very beginning.

Now Daming has directly transitioned to the final stage of wooden rails. The wood is dried, and then asphalt is added for anti-corrosion and insect-proof treatment. In this area, the problem should not be too big.

Now that the car is overturned, on the one hand, the load-bearing structure of the vehicle lacks spring shock absorption, and on the other hand, the design of the wheels is unreasonable.

Today's wheels are only about [-] centimeters in diameter, which is pitifully small compared to the train wheels of later generations.

After Zhu Zhanji saw it at the beginning, he didn't care, because the wheels of the mine carts of later generations were also very small.

But he neglected that the reason for the small size of the wheels is that the rails are made of iron, so the fit between the two sides is relatively stable.

Now the track is made of wood, but small wheels are used, so naturally it cannot be fixed now.

He looked at the exposed wheels under the overturned carriage again, and said, "Enlarge the wheels. In addition to the fixed support on the inner side, the outer side is also curved to wrap the rails."

Ma Zhicai said with some embarrassment: "Your Highness, if this is the case, the wheels will be too big and heavy, and it will be difficult to quench them."

Daming's materials and craftsmanship are not up to standard. Although refined steel can be obtained today, they are basically used to make guns and guns.

Civil goods for train seats need to pay attention to cost control.It is too expensive to make wheels entirely of stainless steel.

So the current wheels are made of iron, and after the wheels are processed, they are quenched to increase their strength.

An iron wheel with a diameter of more than fifty centimeters is nearly ten centimeters thick at its widest point. The weight of this wheel is several hundred kilograms.

At this time, the quenching process is carried out, and all corresponding technologies need to be improved.

Zhu Zhanji asked again: "Is the problem of the transmission part easy to solve?"

Ma Zhicai looked at a deputy in his 40s, and he immediately came out and bowed: "Your Highness, it is not difficult to solve. Nowadays, the use of connecting rods to drive the wheels has gone through many tests. We have tried many times before, but there is no problem." Something went wrong, and this time it was also because there were too many people on the car and it was too heavy, which caused the car to overturn."

Zhu Zhanji shook his head and said: "In my opinion, there are still many problems. First, the load-bearing structure of the load-bearing wheels and the carriage needs to be improved. I think that adding shock absorption at the joint can not only increase the safety of the people on board. Comfort, also prevents rollover.

Second, there is a lack of connection between the wheels on both sides. We should design a connecting rod to connect the wheels on both sides so that the wheels on both sides always keep the same direction, which can also increase power and stability. "

Although Ma Zhicai didn't know if it would be useful, he immediately bowed and said, "Your Highness is wise, I will immediately organize people to solve these problems."

Zhu Zhanji shook his head and said: "My idea is not necessarily correct. As a researcher, you must always face any problem with a skeptical attitude. Only when the new technology has been verified, it is not too late to flatter me. "

At this time, a carriage slowly drove over, and Zhu Zhanji knew it was Lan Yan's driver just by looking at its appearance.

Baiguan immediately gave up a driveway, and after the car stopped, the two court ladies immediately stood at the door of the car and opened it.

Zhu Zhanji took a few steps forward, came to the side of the carriage, stretched out his hand himself, and Lan Yan, wearing a hedge on his head, helped Zhu Zhanji's hand to get off the carriage. "How did you come here?"

Zhu Zhanji's actions are somewhat deviant in this era.

Because in this era, the status of women is very low.But in order to support Lan Yan, Zhu Zhanji doesn't mind being more gentlemanly at this time.

Lan Yan was arranged by Zhu Zhanji at Xiama Bridge, which actually caused quite a disturbance. Several times in the early courts, the censor of the Metropolitan Procuratorate persuaded Zhu Zhanji that women should not be shown in public.

It's just that Zhu Zhanji didn't respond. It's just that Maqiao is his private property, and he let one of his wives take care of it.

Lan Yan took over the Institute of Chemistry and the Institute of Medicine. The staff of the Institute of Chemistry did not dare to say a word when they saw Lan Yan's ability.

They can't wait to learn how to make explosives from Lanyan right now.

As for the Medical Research Institute, Lan Yan didn't take care of it for the time being, and only when they made achievements would everyone be convinced.

In fact, Zhu Zhanji has already decided to let Lan Yan manage the entire Xiamaqiao area, but he has learned to keep a low profile now.

Many things don't have to be known to everyone from the beginning, it is only necessary to let Lan Yan do things first, and when everyone gets used to her presence and cannot do without her, it's not too late to announce.

Seeing the scene in front of her, Lan Yan said in a low voice: "I heard that there was a car accident here, so I came here to see if I can help."

Zhu Zhanji nodded and said: "You came just in time. More than 40 people were injured today, and all of these people were treated as work-related injuries. Even if they were admitted to the hospital, their salary would still be paid, and they would receive free medical treatment. You can help me take care of this matter." .”

When the others heard this, they immediately raised Lan Yan's status a lot.Many people are wondering, if the development continues like this, will His Highness be handed over to Lan Liangdi to take care of Xiamaqiao Farm in the future?

But they didn't have much resistance, because there are more than 3000 Xiyi people living in Xiamaqiao.They have all heard that there are not only female ministers in Xiyi, but also women who became kings.
