"The salt-drying area is the largest area among the four control areas, covering a total area of about 3,000 acres."
“Just walking from here to the seaside embankment would take two hours to get to the seaside embankment.
"In addition, it is not convenient to raise horses because it is close to the seaside. Moreover, if horses are raised within the controlled area, it is easy to bring pollutants such as horse manure."
“So in order to further facilitate travel and cargo transportation within the controlled area, transportation tools such as bicycles and transportation tools such as multi-person bicycles were invented.
While riding his bicycle, Yan Changqing turned his head and looked at the princes Zhu Biao, Zhu Fang, Zhu Fan, Zhu Di and other princes on the open carriage of the multi-person bicycle, and said calmly.
In the process of multitasking, the bicycle he was sitting on was controlled steadily, and there was no phenomenon of picking up or deviating from the route.
After all, in his previous life, he had learned to ride a bicycle at a young age like Zhu Xiongying, and then he rode a bicycle home with him in elementary school, junior high school, and high school.
When I went to university later, I was on the university campus, from the dormitory to the classroom.
Later, when he worked in the research institute, he basically used bicycles as his main means of transportation from the researcher dormitory to the working building.
After all, he has been driving bicycles for more than ten years, if not twenty years.
Not to mention being able to perform 237 downhill bicycle stunts, but he can also do ordinary tricks like letting go of the bicycle handlebars.
Not to mention simply riding a bicycle and talking while being distracted.
Prince Zhu Biao, Zhu Di, Zhu Fan, Zhu Di and other princes stood on the open carriage. They looked at Yan Changqing and others, each of them riding bicycles with great speed and freedom.
A flash of envy, curiosity, and desire couldn't help but flash in his eyes.
After all, in human nature, especially male nature, there is a part of it that chases freedom and the wind!!!
The manifestation of this part of nature is that from ancient times to the present, men have had an affinity for chariots, BMWs, cars, sports cars, and the like, which can allow their speed to catch up with the wind, or even surpass the wind. Extraordinary desire and persistence.
[When I get back, I will buy a bicycle like this and try it out!!!]
At this moment, the same thought flashed through the minds of Prince Zhu Biao, Zhu Di, Zhu Fan, Zhu Di and other princes.
Everyone rode for more than half an hour before arriving at the embankment on the coast.
Yan Changqing took Prince Zhu Biao, Zhu Di, Zhu Fan, Zhu Di and other princes to stroll on the three-foot-high embankment. He looked back at the salt-baking area from a high position and could almost take in the entire salt-baking area.
"Beach sun salt, the process summarized now is generally divided into several major steps such as embankment construction, beach construction, beach repair, brine production, crystallization and collection."
"Among them, embankment construction means building coastal embankments, and then building pipeline sluices on the embankments to regulate the inflow and outflow of tides."
"However, it also has another use, that is, it can also play a certain role in resisting attacks by Japanese pirates and bandits.'
"On this coastal dam, there are a total of twelve pipeline sluices, all buried three feet deep underground, and after entering the sea, they also extend to the bottom of the sea ten feet away!"
"As long as the valve of the submarine pipeline is opened, the submarine tide ten feet away will continue to flow into the salt field through the submarine pipeline."
Yan Changqing stood in front of a valve in a submarine pipeline and said with emotion.
In order to receive the tide conveniently and stably, he did not choose the method of receiving the tide with the rising tide, nor did he choose the method of transporting the tide with a human-powered water tanker.
Instead, they chose to directly build twelve submarine pipelines buried three feet below the ground, which is ten meters under the ground, and ten feet into the sea, which is about thirty-three meters into the sea!!!
Considering the huge corrosive effect of seawater on cement concrete and steel bars.
And the cement concrete he currently prepared is ordinary cement concrete, not special seawater cement concrete that is resistant to seawater corrosion.
Therefore, in order to extend the service life of these submarine pipelines as much as possible, the outer layer of his submarine pipelines is made of cement concrete wrapped with steel bars, and is specially made into a cement-rebar hybrid pipeline.
And inside the cement-steel (bhah) reinforced mixing pipe, there is also a glass pipe made of pure glass!!!
Because the corrosion of glass by sea water is negligible.
However, glass pipes are fragile, so they need to be wrapped with a layer of cement and steel mixed pipes to protect the glass pipes from accidental damage.
And in each section of the pipeline, there are also layers of wire mesh to block seabed organisms or the impact of seabed sand and gravel.
In this way, even if the outer cement-reinforced steel mixed pipe is corroded, as long as its overall structure remains, as long as the internal barrier wire mesh remains.
Then it can ensure that the internal glass pipe will not be damaged by accidental lifting.
At the same time, this hybrid submarine pipeline made of three-in-one cement, steel, and glass can be used forever.
After solving the problem of seawater corrosion of submarine pipelines, the remaining problem is how to bury the submarine pipeline ten meters below the ground and how to let it enter the sea ten feet.
The former is easier to solve. It is nothing more than digging a ten-meter-deep channel from the salt drying area to the seaside.
But after arriving at the seaside, how to make these underground pipes ten meters deep underground and reach thirty-three meters into the sea becomes a big problem.
The last issue is through the construction of temporary water transfer dams on the seaside.
On the other hand, the Ming Dynasty's navy ships dragged the trenching tools to quickly dig channels.
After digging the channel at the same time, the cement reinforced glass pipe was quickly pulled into the submarine channel through other ships.
In the end, we managed to make these submarine pipelines reach 33 meters into the sea.
It can be said that the biggest problem in the construction of the entire seaside salt drying area is this one!!!
However, after solving the problem, the advantage is also obvious, that is, there is no need to consider the head of the tide on sunny days and the tail of the tide on rainy days.
Because when drying sea salt in the past, the reason why we paid attention to collecting the head of the tide on sunny days and the tail of the tide on rainy days was actually the main reason for obtaining seawater with high concentration of salinity on the seabed.
Because of the distribution pattern of seawater salinity, seawater salinity increases with depth.
The head of the tide on sunny days and the tail of the tide on rainy days will roll up the bottom seawater with high concentration of salinity, so if you use the seawater at this time to dry salt, you will get twice the result with half the effort.
But with the submarine pipeline, Yan Changqing can directly obtain stable and relatively high-concentration submarine tides, without having to wait for the tide head on sunny days or the tail tide on rainy days.
