I was engaged in infrastructure construction in the Han Dynasty [Transmigration Book]

Liu Tan actually doesn't have a particularly organized approach to doing things, and most of the time he just thinks about it.

It was the same this time. After having this idea, he felt that this idea was a bit unreliable.

The water park should have water first. The Northern Kingdom does not lack water, but it lacks clean water.

Because Liu Tan wants to build a water park, there must be water slides, and then there are some other water projects, anyway, the project is definitely not small.

He listed the preliminary goals on paper, intending to divide them into water play area and water play area.

The two areas are not connected to each other, and the water play is to watch the water features such as lotus by boat, so the pool must be pure and natural.

In the water play area, because the water quality needs to be clean, it is best to have a swimming pool directly.

But these two need to be taken as a whole. Liu talked and decided, not to mention other things, I am afraid that it will take a month to build these two pools. Even if other things are manufactured at the same time, it cannot be done in a month.

He sighed deeply: "Father, why didn't you come later."

He even began to think about whether to write a letter to Liu Che to make him come later.

Looking at Liu Tan, Zhu Shanyan frowned and said in a low voice: "Your Highness, don't worry, Your Majesty is only traveling in mid-April, and it will take some time to get from Chang'an to the capital, and there is Tongda City in your majesty's itinerary, so His Majesty can do it." Arrange for His Majesty to go to other places to play first, and start construction here at the same time."

After hearing this, Liu Tan realized, yes, he doesn't need to do everything well before Liu Che comes, as long as he can play with Liu Che, it's not Longevity Palace.

Liu Tan patted Zhu Shanyi's shoulder with satisfaction: "Young man has a bright future."

Zhu Shanqian couldn't laugh or cry immediately, he was much older than Liu Tan, but it was cute to see his highness pretending to be old-fashioned.

According to what Zhu Shanzhang said, Liu Tan calculated the time and found that according to Zhu Shanzhang's calculation, he had plenty of time, and there was no need to combine the two water activities together.

Because it is easier to watch on the water than in the swimming pool.

After making up my mind to do it, it is crazy design, first of all, the water play part.

Boats must be used for water play. In fact, Dahan’s building boats have developed pretty well. At least Liu Tan wants to get a cruise boat. It’s not a problem. The flower boat is only two floors at most. Inlaid with glass.

He doesn't need to bother about the cruise ship, just order it casually.

What needs his attention most is actually the item of going into the water to play.

First of all, he has to solve the water quality problem. It is impossible to use groundwater for swimming pools. It must be diverted from the Yellow River, so the water quality needs to be filtered.

Liu Tan chose to choose, and chose at the foot of Yangshan Mountain. First of all, because the river here has not passed through the Loess Plateau, it has not yet carried a large amount of sediment, even if it is filtered, it is easy.

Because Liu Tan doesn't have a particularly good filtering method, he can only use relatively sparse gauze to filter, and prepare multiple filters.

The first filter uses a thinner fishing net to block all the fish and aquatic plants in the water, the second is a finer one to block smaller aquatic organisms, and then the third filter starts from the water sediment and plankton.

Of course, plankton is not easy, there will always be some microorganisms, but it doesn't matter, he will also disinfect the water in the swimming pool with alum.

In this way, at least the water quality can be guaranteed to the greatest extent.

Just as Liu Tan was about to enclose the land on the map, he suddenly remembered his passive "golden finger". After thinking for a while, he handed the map to Zhu Shanzhang and said, "Choose a place at the foot of Yangshan Mountain. I want to use it as a pool."

He didn't want the entire project to be terminated because of digging out the mine, and there was really no place to cry when the time came.

Zhu Shanyu was a little dazed, and didn't understand why His Highness asked him to choose, but he thought that His Highness the King of the North had been preparing for the pick-up.

Even if he didn't know what this place was used for, he instinctively wanted to choose a place with beautiful mountains and rivers.

Before Zhu Shanzhang came to take part in the imperial examination, he was also a person who traveled all over the world. He did go to the foot of Yangshan Mountain. After thinking about the scenery there, he carefully chose a place and said, "Your Highness, the scenery here is not bad. You can see Mountain, but not very close to the mountain."

After all, the Great Wall is above Yangshan, which means that it is too close to the Huns, which is not good.

Liu Tan gave him a very good look, and initially chose this place.

Then he designed the shape of the swimming pool. Because it is not used for competitions, the shape of the swimming pool does not have to be as square as the later generations. He just made it into the shape of a panda's head.

For the panda ears, one is used as a shallow water area for entering the water, and the other is used as a place for slides.

There are no slides these days. Liu Tan is more cautious. He asked people to make a model first, and then experimented a little bit to see which height enters the water with splashes, but it is not so exciting.

He didn't dare to make it too high, if something happened in the middle, he just waited to be a sinner through the ages.

Anyway, it's just an addiction, not these days, so Liu Che won't think it's not exciting enough.

In fact, Liu Tan hesitated for a long time between the slide and the slide.

The difference between slides and slides is that one is driven by water into the pool from top to bottom by boat, and the other is to slide in by yourself.

In the end he thought about it and decided to do both.

It’s just that the slides of later generations are single-person boats made of rubber. There is no rubber these days, and probably only kayaks can be made.

As for the material of the slideway and the slide, Liu Tan decided to make it different after thinking for a long time. The slide was made of wood, polished, and then painted with varnish.

After all, you may not be wearing any clothes when you are on the slide, so try to ensure that there will be no accidents that cause injuries during the slide.

The angle of entry into the water also came to a result after model experiments.

Of course, this cannot be used as the final basis, so Liu Tan asked people to build a slide next to his pool, and then asked people to conduct experiments, and then asked people to make a slide of a suitable height after ensuring everything was safe.

As for the waterproofing of the wood, anyway, Liu Che will stay here for three months, as long as he guarantees that the slide will be fine within three months.

After three months, the pool will be emptied.

Liu Tan himself is not interested in playing in the past, he is too busy, how can he have time to play that?

So this slide is basically a one-off. If it was in the past, Liu Tan would still think it was too extravagant.

Now... Forget it, let's be extravagant, at least he can give the people some work to do if he is extravagant, otherwise the money will not be able to be put in the treasury.

After the slide is done, there is the slideway. The slideway is different from the slideway. Because it spirals down from a high place, it needs to be stronger. Liu Tan simply used a stone slideway.

The height is still not set too high, for fear of accidents, and then the interception net must be laid outside the slideway, so that even if it falls from above, it can fall on the net without injury.

Because the spiral fall also has a certain acceleration, Liu Tan thought about it and added a little stimulation part-made a short ramp before entering the water at the end, and let the kayak rush up the ramp through the acceleration of gravity, and then quickly from the ramp slipped into the water.

This should make Liu Che feel interesting.

In fact, the slides and kayaks are not difficult to solve, the only difficult problem is the water flow inside the slide.

Because of gravity, it is impossible for water to flow from a low place to a high place, so how to transport the water up becomes a problem.

Seeing Liu Tan worrying there, Miao Rui couldn't help laughing and said: "Your Highness, don't worry, how to transport water in the coal mine, how to transport water here."

Liu Tan shook his head: "It's not the same, not to mention that the amount of water transported there is not large, but the equipment is problematic, which is too ugly."

Miao Rui shut up decisively, this is a playground designed for the emperor, of course no ugly things can appear.

There will be no ugly things. Is it necessary to lift the water up by manpower?

Of course Liu Tan wouldn't be so mad, and the efficiency of manpower lifting water is too slow, I'm afraid it's not enough for fun.

He thought for a while and wrote two words on the paper: waterwheel.
