Since everyone was clamoring to go, Yang Fan had no choice but to take his whole family to the construction site of the interception headquarters.
Yang Fan attaches great importance to this dam. After the dam is repaired, it will be able to irrigate millions of acres of land downstream as far as Beitangkou. At least 500,000 acres of paddy fields will be developed on Yang Fan's territory.
Coupled with the use of high-quality seeds brought here, feeding a million people will not be a problem.
If Yang Fan wants to develop industry in the Ming Dynasty, he must first have enough food to support it. Agriculture is the basis of industry. Without enough food, it is impossible to feed a large number of workers.
Moreover, the raw materials for light industry also come from agriculture, such as the textile industry. Cotton, linen and other silk fabrics all rely on agricultural output.
In addition to providing water for agricultural irrigation, this reservoir also plays an important role in providing a source of power for industrial production.
In the era before steam engines, if you wanted to develop industry rather than handicrafts, you had to find a stable source of power.
In this era, in addition to human and animal power, which were considered stable sources of power, wind energy was also barely available, but the power was too small and could only be used to build mills.
Only hydraulic power is the only option.
Whether it is rolling steel, forging, hammering, or driving textile machinery, the power of water flow can be stably output for production.
Ordinary small rivers will stop production due to freezing in winter. However, such a large reservoir will not be affected by seasons.
Because the power flow of the reservoir flows from the bottom, the factory's water tanks are also buried underground to prevent freezing in winter.
The underground power tank directly enters the lower layer of the river. Even if the river surface freezes, it can still drain water. It can basically maintain production all year round.
Yang Fan found a water conservancy engineer in modern times and got a complete set of drawings of this later reservoir dam. This dam was built in 1959. The conditions at that time were very poor. It was basically carried on people's backs and shoulders without any engineering machinery.
Therefore, it was possible to make use of Yang Fan's existing conditions.
Moreover, the performance of the modern materials shipped by Yang Fan is far better than that of the materials from 1959. Whether it is steel or cement, they are much better, and the quality is more guaranteed.
After the water is impounded here, the length of the lake reaches 35 kilometers from east to west and about 7 kilometers from north to south. The total storage capacity is 100 million cubic meters, and the normal water storage level is meters. The main buildings include a barrage, a flood discharge tunnel (also a power tunnel), a spillway, and a power station.
Because he used a complete set of drawings from later generations, which included a power plant, Yang Fan decided to start the construction of the dam first and reserve space for installing electrical equipment. He would wait until the technology tree was up.
In fact, hydroelectric generators are not a difficult technology. Using pure copper through small holes of different diameters, copper wires of various thicknesses can be pulled out.
The copper wire used on cloisonné in the Ming Dynasty was drawn in this way, and this technology existed during the Warring States Period.
Insulated enameled wires can be produced by spraying the natural lacquer produced on the lacquer trees of this era.
After drying, the enameled wire made of lacquer has very good waterproof performance and is corrosion-resistant and wear-resistant, no worse than today's plastic materials.
With enameled wire, it is not impossible to develop the electronic industry in the future, such as mineral radios, cable broadcasts, cable telegraphs, radios, etc.
The unearthed lacquerware has been as good as new for thousands of years, which shows how good its waterproof and anti-corrosion properties are. Ancient leather armor was repeatedly coated with lacquer, and its hardness can resist swords, which shows its wear resistance.
The only disadvantage is that it is expensive. You can only cut one or two large pieces of lacquer from a lacquer tree a year, otherwise it will cause damage to the tree.
With the enameled wire, you only need to wind it into coils of various specifications, cast the generator components, and then assemble them. Add the cast turbine blades, and you can produce the generator yourself.
Nothing difficult.
After completion, the reservoir dam has a total length of 2,222 meters and a maximum dam height of 24 meters. It also has multiple functions such as flood control, urban water supply, agricultural irrigation, and power generation.
Yang Fan, sisters Tu Shanyue, Lin Yueru, Mei Xiang, Yao Guang, Xiang Yi, etc. all changed into work clothes and wore safety helmets because they went to the construction site.
This helmet was also passed down from later generations. It is of the highest quality standard. Yang Fan doesn't want his girls to have their heads smashed by bricks from the construction site.
Not to mention, beauties look good in anything they wear. A few girls put on dark blue jackets and overalls, white cotton socks, sneakers, and safety helmets for a unique look.
Yang Fan felt itchy in his heart when he saw it.
These girls are more eye-catching when they wear modern clothes.
Yang Fan said in his heart, Damn it, it turns out that I can subdue this one easily.
Yang Fan took out a box and handed it to Tu Shanyue. Inside were ten Seagull Tourbillon women's watches.
"This is a timepiece, which can also be called a watch. Well, it stays on your wrist like this and you can tell the time. Each large scale is half an hour, also called an hour. The three rotating hands are called hour hand, minute hand and
Second hand. You guys will be divided into two pieces." Yang Fan introduced.
As soon as the watch was taken out, the girls immediately became red-eyed and all gathered around.
It can be seen that it is a girl’s nature to like watches.
These watches are all made of solid gold hardened cases and inlaid with Tanzanian diamonds. The small Kun watches are very exquisitely designed, especially suitable for girls' bright wrists.
There are many famous watches in the world, but Yang Fan just doesn't buy them and firmly supports domestic products.
This domestically produced Seagull Tourbillon is not cheap either, with a price of around 200,000 yuan.
Tushan smiled with a bright eyebrow. He picked the one he was satisfied with first, and then shared it with others.
She was very satisfied with Yang Fan's performance. She had the final say in the family. Any rewards given to them by the master must be distributed through her hands. This was her right.
Except for Yao Guang who brought an expensive Patek Philippe and looked down upon it, the others even got a piece from Xiao Hong and Xiao Yu. They were so happy that they didn't want to give it up.
Naturally, no one dares to compare with Yao Guang. She is a special existence in the Yang family's backyard.
Commander-in-Chief Song Yingxing and his students had been waiting at the gate of the construction site early. Today they got the news that the master and his wife were here to inspect the work and would stay here for a while to personally supervise the closure of the canyon. They all became nervous.
This chapter is not over yet, please click on the next page to continue reading! First it’s cleaning, and then the place is ready.
"Let's go see the diversion channel and the water diversion tunnel first." Yang Fan's first words when he saw Song Yingxing was to see the tunnel and the water diversion tunnel.
Song Yingxing quickly waved his hand and dismissed the gongs, drums and suona players. It seems that the master does not like this kind of welcome. It will directly depend on the progress of the project.
Song Yingxing quickly took Yang Fan and his party to the diversion channel.
Yang Fan saw that the channels here were made of granite and cement. They were very strong and were now dry enough to drain water.
Yang Fan nodded with satisfaction.
Song Yingxing quickly reported on the various engineering parameters of the open channel. To Yang Fan's surprise, Tu Shanyue and Lin Yueru actually asked a lot of very professional questions.
Song Yingxing knew that these two ladies were very important, so he respectfully explained them one by one in detail.
"After the flow was intercepted, the water flowed away from the open diversion channel, right?" Tu Shanyue asked.
"Yes, madam, this is equivalent to preventing the river from flowing along the river. Then only after the river is intercepted can a dam be built at the mouth of the river."
"Will this diversion channel and tunnel be useless after the dam is repaired?" Lin Yueru also asked a more in-depth question.
"Mrs. Lin, you can't say that. This can be used as a flood discharge channel during the flood season. In addition, I want to build an industrial zone downstream of the dam. In the future, part of the power water may also be diverted from here. I said that in the future, we can also use it in the tunnel.
A power plant is being built next to it. I don’t know much about this power plant, but there is a reserved factory building on the design drawing.”
Lin Yueru knew about electricity, because Yang Fan used solar panels to wire the house in Dongsi's mansion. He had also seen light bulbs. She nodded without asking any more questions.
Tu Shanyue and Lin Yueru both saw that what the master was going to do was an unprecedented big undertaking. If they wanted to always be favored by the master, they had to keep up with his development. Therefore, they competed with each other and both
Working very hard to learn all new knowledge.
Yang Fan is also happy to see this. He hopes that his wives can become new women instead of pleasing him.
"Okay, Tushan workers and forest workers, we're going to see the tunnel." Seeing that they didn't have any new questions, Yang Fan greeted them and left.
Tu Shanyue and Lin Yueru knew that this meant calling them engineers. Although Yang Fan was joking, they were quite excited to be called engineers.
At the end of the diversion channel is a tunnel that passes through the mountain. There are hard stone mountains on both sides of the gorge. Yang Fan looked at the diversion tunnel with a diameter of about five meters and said with emotion: "It's really difficult for you to dig such a long tunnel.
.”
"Master, this tunnel is really difficult to dig. Twenty-four groups of people took turns working day and night for half a year. Fortunately, new explosives were shipped later, which speeded up the process. It took three months to dig the 20 meters in front, and the tunnel behind
Forty meters, I used a steel drill to drill the holes and fired the cannons. The speed picked up immediately, and the digging was completed in a month."
Yang Fan was also very excited when he looked at the bright tunnel illuminated by carbide lamps. This should be the first artificially excavated tunnel project in the Ming Dynasty.
