Among the water conservancy projects in all dynasties, there are many projects with earthworks exceeding the pyramids. Some water conservancy projects even date back to the third generation, that is, when metal products have not yet been popularized. In such an era, to complete a super project, the problems to be solved are: human organization and engineering design ideas.

Reflected to the context of civilization, it is the extreme precocious maturity of Chinese civilization and the extreme reality of technology application.

This is why "empirical science" appears in a large number of industries rather than summarizing a universal theorem.

The whole idea is that when I need a dam to intercept floods, what I think of is not to find a mathematical tool to calculate first, but... to find someone who has a great amount of soil calculating.

This idea was generally seen in various leadership positions until Lao Zhang illegally traveled through time, especially when outsiders led experts.

Fortunately, in the field of engineering dogs, even if you are a liberal arts student, you generally won’t be forced to do anything, and everyone is quite harmonious.

If there is a liberal arts leader who wants to force him... it is usually done in one go, and the people of the whole country will watch the court live broadcast and eat braised dog meat.

Who told you to do the tofu project? What did you do?

Although the scale of water conservancy projects is extremely large, they cannot intimidate the entire audience due to their geographical location.

After all, in the past dynasties, except for the emergence of the Three Gorges Dam on the Yangtze River thousands and hundreds of years later, it has formed the interest of the people to watch, allowing the onlookers to receive tickets to watch the "miracle". Before this, it was impossible for anyone to watch water conservancy projects on purpose.

Even the Three Gorges Dam... there are air defense missiles nearby. Several patrol and defense yamen were set up in Dujiangyan in all dynasties, which were all basic operations.

If you encounter someone who wants to learn from Guan Yu’s good example, Isn’t this a mess?

The combination of various reasons has made the "Human Emperors" who mastered the magical artifacts of the country often shocked their opponents and potential opponents when developing a major project of water conservancy projects, and then consumed a large number of stubborn elements in the project to achieve great success. As for the future, they would give the world a "hard dish", most of them would use their own private property.

For example, Changle Palace, Weiyang Palace, Tai Chi Palace, Daming Palace, Luoyang Palace...

When building a high platform on the flat ground, you have to look at the corners of the palace walls and walls. When the ordinary master passed by, he saw the bridge between the high platform and pavilion, he felt that the emperor was a god.

The Cangtou Guizhou leaders who had not studied were shocked at the time, so naturally they did not dare to think that "that can be replaced."

A rare hero like Liu Bang and Xiang Yu have always been a minority. Most of the time, I ask the locals why they don’t even dare to think about it?

The answers of the locals are also very consistent: This is how we uneducated people...

Of course, the "Human Emperors" who mastered the magical artifacts of the country will not only show off their family background and shock the audience, but also dragged the servants and guards out to show off their appearance. They would dance to the relatives at every turn. When the locals saw so many old brothers, they could not cut them, and they dared not move.

As the locals gradually produced cultural desperation, this deterrence effect was much worse, so the engineering wonders gradually decreased. After all, the wonders were so much a loser.

However, history is spiraling up. After entering the industrial age, the role of "miracle" once again bursts out with amazing charm. Because behind each "miracle" is reflected the industrial strength required to build "miracle".

Whether the country is strong or not can be seen at a glance.

Similarly, the way of showing off the housekeepers' hospital protection has also undergone drastic changes. The equipment used by the housekeepers' hospital protection is itself a "miracle". Giant cannon ships, heavy aircraft carriers... cannot be equipped with non-top countries.

The principle of being matched with the master is that the overlord must be counterweighted. This is the truth since ancient times.

A local dog in the 23rd year of Zhenguan did not want to control the entire venue. However, no matter how many miles of river embankment he built, how many ponds and dams he built, or moved mountains and filled lakes or "encircled dikes and built fields", the number of people he saw was a minority after all. Who had enough to eat and had nothing to do to calculate the project volume here and there, and then shocked the fierce strength of the dogs in Wuhan?

After all, there must be "hard dishes" on the desktop.

Just like Emperor Li’s Tai Chi Palace and Daming Palace, it will be a king’s bomb when throwing it out. Regardless of whether your aristocratic family or wealthy family, whether your military head or a rude leader, you will bow when you see it, and kneel when you see it.

The extraordinary aura that naturally produces will make Xiao Xiao despair.

Lao Zhang didn't mind being a little slaughtered. He suffered no less assassination every year than Emperor Li.

Death is no big deal for him, an engineering dog who illegally travels through time. However, someone wants to interrupt his hard work in the Internet... This is unbearable.

A local dog in Jiangnan who was busy with documentaries in Wuhan just wanted to say: I just want to go online, but the worst thing is that I want to practice typing with the Xiaobawang learning machine. Is there anything wrong?

Zhang De, who was severely "Internet addiction", and a group of Wuhan local dogs who wanted to "make trouble", naturally wanted to take out a guy. It was black and hard, thick and long. The man felt inferior when he saw it, and the woman cried when he saw it.

In the experimental area of ​​Hanyang Iron and Steel Plant and the inner factory, in front of a ditch several meters wide, the components that were riveting were passed through a counterweight crane to form an "X" shape. Next to it, the master who was debugging anti-rust paint frowned slightly, and Zhang De covered his nose and asked, "What's going on?"

"The mountain chief, this paint has been left for three days and has been a little solidified. I am afraid it needs to be adjusted and used immediately."

The red and yellow anti-rust paint uses lead elixir and tung oil, which is very low in cost, but the trouble is that it is easy to condense after being left to stand.

"Then use it now."

It is hard to say how strong the toxicity is, but it is still a bit toxic after all. The worker wearing goggles and homemade breathing masks constantly paints the components. This is a comparative experiment. What proportion of anti-rust paint is used depends on the experimental results.

"The mountain leader can actually use bolts."

"Do you think the people who steal iron are ordinary people?"

Zhang De glanced over and said that Hanyang Iron and Steel Plant was able to produce qualified bolts, but it was meaningless. In recent years, iron stealing skills were very strong. Wuhan just made a bolt structure, and there was an expert in iron stealing in Yangzhou who used copper coins to melt it and then processed a bronze wrench...

There are 10 or 20 guards around the entire Hanyang Iron and Steel Plant. In addition to the full guards, the steel mill workers also have security services.

Although pig iron can be mass-produced, looking at the supermarkets of 30 million people across the country, this amount is not enough.

Not to mention 30 million people, even if it is a market of 33 billion, the iron price is as low as mud, what should be stolen or what should be stolen... Iron must be used forever.

This is hard currency that can't be harder.

The iron bridges erected at the test site are not one or two, but they are most favored by people. They are a suspension bridge called "iron" by steel mills.

Suspension bridges have a long history, and "南" itself means bamboo suspension bridge. During the reign of Emperor Ming of Han, "南" was used extensively in the southwest, and there were also iron chain bridges. Regarding the experience on iron bridges, this is the only thing that can be learned from contemporary bridge engineering dogs.

Whether in terms of construction difficulty or processing and assembly technology, it is indeed the safest and easy. After all, chains can be used for suspension cables, which is the flagship product of Hanyang Iron and Steel Plant.

However, what Lao Zhang cares about is not technically, but rather that the suspension bridge is easier to pack, and the main beam of the bridge head is decorated, making the effect more shocking.

Whether it is the bridgehead made into a dragon's head and a dragon's tail, or the "divine beast" in the bridge where the main beams on both sides are poured with iron, it is enough to leave a deep impression on people.

Moreover, the suspension bridge can build the main beam very high. Even if it is not so high, for the sake of showing off, you can choose to be higher.

"How to solve the problem of thermal expansion and contraction?"

Zhang De asked casually.

“Trigger.”

A big worker responded, "Even if the span of the 'Lihe' is not cut, it will not affect too much thermal expansion and contraction."

However, the span of the "Lihe" is not large, but the bridge was not built according to the span of the "Lihe". The length extended on both sides was deliberately lengthened to give people the illusion of the view of this bridge that is particularly large.

There is no way to do this. "Hard food" needs to be raised, but the gullies are too wide... It is common to not be hard.
