The most arrogant in history

Chapter 218: Master of Passing the Buck.

Ye Qingyang shrugged: "The two masters who designed the plan are both dead."

There is no evidence to prove the fault if you put the blame on the dead.

It seems that Ye Qingyang is also a master at passing the buck.

Ye Kun sighed and called the other chefs:

"The river is 50 feet wide, and the bridge is designed so that the span can be increased to 70 feet, which will make it more solid. Because the river banks on both sides are easily impacted by the flowing water and cause landslides, a safe distance must be reserved."

The masters complained: "But the wood is not long enough. We designed it so that two pieces of wood are connected to form the length of the bridge deck. If it is extended to seven meters, three pieces of wood will be needed to connect them. The bridge piers below will need more..."

"You know nothing about the Arch Bridge and the Feihong Bridge."

Ye Kun sighed and asked his personal soldiers to bring him a pair of chopsticks and some bamboo strips.

In the middle of the night, Ye Kun was teaching everyone by the river.

Let’s talk about arch bridges first.

"This long bamboo strip, when supported at both ends, becomes a bridge. But it cannot bear the weight of half a brick."

Ye Kun demonstrated and explained:

"Now, we still use this strip of bamboo to make an arch bridge. The same material can bear the weight of a brick. This is an arch bridge. There is no need for piers under the arch. As long as the design is good and the material is durable, it can last for thousands of years."

The masters nodded one after another: "Small bridges can be repaired this way, but large bridges have never been repaired before, and the wood is not long enough..."

There were arch bridges in the Dading Kingdom, but they were all small bridges with a span of only one or two meters.

No one dared to imagine building an arch bridge with a span of sixty or seventy meters.

"The wood isn't long enough, I can't splice it together?" Ye Kun was upset and pointed at the river in front of him:

"For a small river like this, a wooden arch bridge can be designed. It does not need piers and can be used for decades. If it is made into a stone arch bridge, it will not break down for a thousand years."

The Zhaozhou Bridge from the Sui and Tang Dynasties is still in use today. The bridge is 50 meters long, with a large arch that is nearly 40 meters long.

The small river in front of me is only a dozen meters wide.

If we really want to build a stone arch bridge, we can do it. Building a wooden arch bridge is even easier.

The chefs were all afraid and didn't want to take responsibility, so they all said:

"If Lord Ye thinks it is feasible, please ask Lord Ye to provide the blueprints and we will be responsible for the construction."

"Okay, I'll draw up the blueprints. We'll have the main structure of the bridge ready in three to five days!"

Ye Kun was not embarrassed at all and continued teaching everyone: "You have seen the arch bridge I just talked about before. Now I will tell you about one you have never seen before, called Feihong Bridge."

The so-called Feihong Bridge is the wooden bridge in "Along the River During the Qingming Festival". It is made up of multiple square wooden frames connected end to end.

The shape is similar to an arch bridge, but it can only be made of wood.

In the West, such bridges only appeared during the Renaissance and were called the Leonardo da Vinci Bridge because they were invented by Leonardo da Vinci.

Ye Kun used chopsticks and thin twine to demonstrate the Feihong Bridge, explained the principle, and asked Lao He and his daughter to help.

Soon, a simple Feihong Bridge model appeared in front of everyone.

Ye Kun put a brick on it, and it was as stable as a mountain.

In the militia training manual, there is a temporary marching bridge built with bamboo, which is also based on the principle of Feihong Bridge. Ye Kun and his comrades had built it before.

Just looking at the frame of this thing, it doesn't seem to be sturdy enough.

However, as the two ends are deeply buried and fixed, and the bridge deck is covered with wooden planks, it is very strong and stable and can accommodate horses and vehicles.

If the wood is treated with anti-corrosion and properly maintained, it can be used for thirty to fifty years without any problems!

The bridge repairmen were amazed and exclaimed in amazement.

Ye Qingyang and other road officials also admired Ye Kun very much.

Ye Kun calculated the size of the model and made a decision on the spot:

"For the bridge ahead, let's use Feihong Bridge. Lao He, you and Tian Tian, ​​please work hard to make a standard model, mark the dimensions, and then start construction immediately."

The construction of Feihong Bridge was very fast.

As for the bridge in front of us, if there are enough bamboos to build a temporary marching bridge, Ye Kun and his twenty brothers can complete it in one day.

Lao He was happy to accept the challenge and said with a smile: "Master Ye, you go and have a rest. Leave this to me and the masters!"

"You guys go and have some rest too, we'll talk after lunch."

Ye Kun waved his hand and dissolved the meeting.

By this time it was daybreak and everyone was very tired.

Lao He, a scientific research fanatic, did not sleep. He went to work after eating something. Together with He Tiantian and several bridge repairmen, they made a standard model in an hour, determined the specific size of the bridge, and the construction plan for each step.

Ye Kun slept for two hours, got up to have lunch, and ordered Lao He and his daughter to go to rest.

Ye Kun personally supervised the construction work in the afternoon and repeatedly emphasized safe construction.

Without lifting equipment, a bridge with a span of seven meters would require springboards at both ends.

Place the huge tree on the shore, press down the back with a lot of sandbags, and let the front end protrude out of the river to serve as a springboard.

Lay some wood between the two springboards to make a flat bridge.

If the springboard protruding from the river surface is slightly raised and then connected with arch wood, it will become a wooden arch bridge.

Ye Kun considered the stress problem and found that neither the flat bridge nor the wooden arch bridge was as good as the Feihong Bridge. Therefore, he decided to build the Feihong Bridge and let everyone master the technology.

That afternoon, the gangplanks at both ends were set up.

Lao He and the craftsmen adjusted the size of the wood overnight and all the materials were ready.

By the evening of the next day, the main structure of Feihong Bridge was completed and it spanned the river, as stable as Mount Tai.

After dinner, Ye Kun gave everyone another lesson, explaining several types of suspension bridges.

Ye Kun was not an expert on roads and bridges, but he had seen suspension bridges of later generations, and after a little thought, he understood their mechanical principles.

According to Ye Kun's experience, there are only two types of suspension bridges in later generations.

One method is to drive piles in the middle of the river, set up a tall pillar in the middle, and pull ropes from the middle to both sides.

One method is to set up tall columns on both sides of the river to pull the middle bridge deck in opposite directions.

Ye Kun can demonstrate the theory and model of suspension bridge, but this technology cannot be promoted at present.

Because there is no steel cable.

Using hemp rope as a suspension rope can only ensure temporary use.

It would be a good idea to first develop the theory and model so that everyone can see them.

The next morning, Ye Kun left Fuling County and instructed Lu Caoguan and Ye Qingyang:

"Check all the roads and ancient bridges in this county, build more arch bridges and flying rainbow bridges, start with small bridges, accumulate experience, and slowly build large bridges. One is to facilitate transportation, and the other is to train our professional road and bridge masters. By the way, if there is a major safety accident again, military law will be imposed!"

Ye Kun gave generous compensation to the workers who were killed or injured in this incident, and also took Ye Qingyang and others to visit the families of the workers and solve their practical difficulties.

Ye Qingyang shrugged and said, "Master Ye, why don't you find someone else to repair the bridge and the road, and Qin Chou and I will be responsible for agricultural production."

Being responsible for agricultural production is much safer.

Ye Kun rolled his eyes: "No, it has to be you who builds the bridge and the road. If you are unsure about the technology, show the plan to Lao He."

The country of Dading is seriously bureaucratic and has few practical people.

Ye Qingyang is not very good at his profession, but he is practical and willing to work hard to climb mountains and cross rivers, so he is considered a talent that Ye Kun relies on.

If you are not good at your major, you can learn it slowly. There is not much high technology in building roads and bridges these days.

After returning to Dongba City, Ye Kun and Lao He brought craftsmen to manufacture standard models of arch bridges, Feihong Bridges and suspension bridges, and vigorously promoted bridge-building technology.

While making the model, Ye Kun had bad luck and cut his finger, spilling blood all over the laboratory.

He Tiantian felt very distressed. She bandaged Ye Kun and sighed softly, "Master Ye, you are really different from others..."

"What's the difference?" Ye Kun was stunned.
