Chapter 301 Different Attitudes
Shengli Desalination Plant near Shengli Oilfield.

After three months of continuous construction, an overhead water pipeline with a length of more than 120 kilometers was extended from Yong’an to near Huimin.

The entire construction time of the overhead water pipeline took only about 96 days.

At this time, a large number of concrete foundations have been started along the straight line of about 100 kilometers from Huimin to Dezhou.

A large Blue Whale transport airship, carrying an overhead bridge made of foam silicon weighing 2000 tons, flew from the Yecheng Special Component Factory to the vicinity of Huimin.

The foam silicone overhead bridge was slowly lowered, and then with the cooperation of the ground personnel, the bridge was accurately connected to the two concrete foundations below.

At the same time, the steel water pipeline that had already been transported was also lifted up by another engineering airship at the construction site and steadily hoisted onto the overhead bridge.

Although the airship hoisting connected this section of steel water pipeline to the previously laid pipeline, there was still a small gap between the two. The welding team immediately entered the pipeline and fully welded the connecting seam from the inside of the pipeline.

at the same time.

At the Shengli Desalination Plant, some of the desalinated water has actually been transported to Kenli District, Lijin County and other places through pipelines.

However, the amount of crude salt produced these days has reached hundreds of thousands of tons. Originally, the factory planned to follow the example of the seawater desalination plants in the south, seal the crude salt in containers woven with silicon wire, and then carry out land reclamation on site.

But after some research, I still feel that this is not appropriate.

A key point is that the area of ​​Bohai Sea is too small. In addition, the Yellow River, Liao River and Haihe River inject silt into the Bohai Sea every year. Over the past few thousand years, the continuous injection of silt has caused a large reduction in the area of ​​Bohai Sea.

If we add another crude salt reclamation now, it is estimated that the water area of ​​Bohai Sea will be further compressed. As Bohai Sea is an inland sea, land reclamation is very uneconomical.

Therefore, the company cooperated with the Chinese Academy of Sciences, and after several months of research and discussion, finally found a compromise solution.

At this time, on one side of the desalination plant, a large deep-water port had been built using foam silicon material extending toward the distant sea surface.

This is a crude salt conveyor belt, which continuously transports the crude salt produced by the factory to the dock. At this time, several “ships” are docked at the berth of the dock.

If you look down from a high altitude, you can find that these ships are very square, almost a standard rectangular block.

These ships are actually simple containers made of foam silicon and silicon bean silk as raw materials. The maximum weight of each container plus its contents is 2000 tons. The reason for 2000 tons is that the current maximum lifting weight of a transport airship is 2000 tons.

Of course, these square ships were not transported by airships, but by barges and transported by sea to the coast of Su Province as raw materials for land reclamation.

The reason why it is pulled to the coast of Jiangsu Province is that the East China Sea is an international sea, and land reclamation will naturally not cause the loss of one’s own inland sea.

On the other hand, due to the drastic climate changes this year, the sea level in coastal areas around the world has risen significantly since May.

According to this trend, if the Antarctic ice sheet melts on a large scale in the future, the consequence will be that low-lying coastal areas will be completely submerged.

Therefore, the country is already planning to build new coastal dams, especially in the low-lying coastal areas of Jiangsu Province, the Yangtze River Delta region, and the Pearl River Delta region. These are the most important areas in the country, and we naturally cannot allow the sea water to flood these areas.

In the past, if it were to build such a large-scale dam, everyone would probably feel that it would be a waste of time and money. But now it is different. Foam silicon materials can reduce the construction cost by nearly half, and the dam construction time can be shortened to about one-third.

This makes coastal dams possible.

In fact, the coastal areas of Jiangsu Province, the Yangtze River Delta region, and the Pearl River Delta region have already taken action. They have each obtained technical authorization from Hailufeng Company and are now working at full capacity to produce foam silicon materials, preparing to first build a circle of coastal dams with a height of about 20 meters above sea level.

At the same time, in order to ensure that sea transportation will not be affected in the future, these areas plan to build artificial islands in shallow sea areas outside the coastal dams as new artificial ports.

There is no way. China is now the best region in the world for carbon reduction, but it still cannot suppress the general trend of global warming.

The reason for this situation is that, on the one hand, carbon emissions in other parts of the world are still high, especially in India, which has been clamoring to become the next world factory in recent years. Various pollutions in its industrial development process are becoming more and more serious.

Europe and the United States are burning forests every other day, resulting in a continuous increase in carbon dioxide.

Even if China has reduced a large amount of carbon dioxide by transforming deserts and growing soybeans, it still cannot stop the world’s increasing carbon emissions.

Increasingly extreme weather has forced the country to think about the negative impact of future sea level rise.

Since the rise in sea levels is difficult to stop, making preparations in advance is naturally a top priority.

However, the previous project in cooperation with Egypt can delay the rise of sea levels.

The depression is about 1.5 square kilometers and can accommodate at least part of the new seawater.

In addition, the continuous extraction of seawater by desalination plants can also reduce the amount of water in the ocean by a small amount.

These projects are, after all, a drop in the bucket. Faced with the ever-melting Antarctic ice sheet and the volatile Arctic ice sheet, sea level rise is almost certain.

At present, the crude salt produced by Shengli Desalination Plant is directly pulled to the coast of Jiangsu Province by square ships similar to the centipede ships commonly seen on the Beijing-Hangzhou Grand Canal. The watertight compartments of the square ships are then pierced and the square ships will automatically sink to the bottom of the sea.

The design of the square boat is divided into three compartments, the front and back compartments are filled with coarse salt, and the middle compartment provides buoyancy.

At this time, on the dock, there was a square ship that had been filled with crude salt. The staff poured some mud and sand into it to form a barrier layer on the surface of the crude salt.

Next, the steel plate composited with silicon bean silk fabric was hoisted in, the steel plate was firmly fixed, and finally the entire panel was welded together using electric welding.

Several staff members took anti-corrosion paint and sprayed several layers of the welding position, and also attached several layers of sparse silicon bean silk gauze to increase the overall strength and corrosion resistance.

After the square ship was sealed, 20 square ships were connected together, pulled by barges, and slowly sailed towards the coast of Su Province along the coastal route.

These square ships are disposable products, and their buoyancy compartments are directly pierced when they reach their destination.

As aggregate for coastal reclamation, it can reduce a lot of raw material costs for reclamation and also make use of crude salt waste.

At the same time, a project was launched along the Yellow River, which is a sand pumping and damming project. This project is similar to the crude salt reclamation of seawater desalination plants.

One is to use discarded coarse salt.

One is to use the difficult-to-use Yellow River sand.

There is no way. The sand from the Yellow River is different from the sand from other rivers. The particle size of the sand from the Yellow River is relatively small and it is very smooth. It is not a qualified building material, otherwise the country would have pumped sand from the Yellow River long ago.

The purpose of launching this project now is, on the one hand, to solve the problem of siltation in the lower reaches of the Yellow River; on the other hand, to provide raw materials for coastal dams in the coastal areas of the Bohai Sea.

The pumped-out river sand is passed through a large electromagnet to absorb the iron sand and some magnetic metals in the sand. The iron sand is used as iron ore. Then it is sieved to select the river sand with larger particle size for use as building materials.

The remaining mud and sand were all filled into containers similar to square ships and transported to the coast of Bohai Sea by airships to be used as raw materials for artificial mountains.

After more than a month of continuous sand pumping, a coastal dam with an altitude of about 20 meters has been formed in the Bohai area near the Nanpai River.

However, unlike coarse salt, these containers filled with Yellow River silt are not sealed but completely open to the sky.

In order to increase economic benefits, the open mud and sand above these coastal dams are planted with genetically modified rootstocks and used as a site for growing cherries.

Residents living near the Nanpai River have gone from being surprised at first to being used to it now.

Large transport airships fly back and forth every day, lifting dam bodies filled with mud and sand and building them on the dam like stacking building blocks.

It seems that this kind of dam is not very reliable.

But what if the dam is several kilometers wide?

That’s right, the design standard for dam width along the coast of Bohai Bay is at least 5 kilometers.

Unless there is a place nearby that is 30 meters above sea level, the pile will fill a width of 5 kilometers.

In this way, even an ordinary gravity dam can block the water pressure impact caused by rising sea levels.

These embankments can be used as new farmland, orchards, roads and residential areas.

The lower reaches of the Yellow River, which is constantly being drained of sand, will become a new, deeper river.

Of course, in addition to this, there is also a man-made lake.

The authorities are already planning to transform part of the desert south of the desert into farmland and use it as a resettlement area for immigrants from Qi, Lu, Hebei and Henan provinces.

Because the government plans to build 15 to 20 large artificial lakes along the lower reaches of the Yellow River. These lakes will be located in some low-lying areas or ancient lake sites.

These artificial lakes can store rainfall from summer rainstorms and regulate the climate of the North China Plain. The excavated silt can also be used as raw materials for coastal embankments.

Although part of the plains was lost, this is a better result than the rising sea level that would flood the low-lying coastal areas.

As for whether these artificial lakes will drain the Yellow River, there is actually no need to worry about this issue.

Because desalination plants are popping up all over the Bohai Bay like mushrooms after a rain, the continuous injection of fresh water into these lakes will solve the local water shortage problem.

As for the precipitation caused by global warming and rising sea levels, there are actually still many controversies among many scientific research teams of the Chinese Academy of Sciences regarding their research on this trend.

No one dares to guarantee that global warming will lead to more precipitation in the North China Plain.

Because the global climate is changing suddenly and more and more extreme weather is occurring, weather forecasting has become more difficult.

If we look at it on an annual scale, precipitation in the North China Plain may have indeed increased.

But if we look at it on a monthly scale, we may have a rainy season in the summer with heavy rains and a dry season in the winter with no snow.

This situation is even more deadly.

You should know that winter wheat is widely grown in the North China Plain. Winter wheat requires snow in winter, and the amount of snow must be relatively heavy.

If there is no snow in the North China Plain in winter, the winter wheat harvest will be very poor.

Therefore, a number of artificial lakes are being built to deal with this situation.

Artificial lakes can store water in the rainy season, increase local flood storage capacity, ensure agricultural water use in the dry season, and regulate the local microclimate.

The emergence of these projects is to cope with an unpredictable future.

However, compared with the positive response at home, the foreign response seems much more passive.

Even the old developed countries such as Europe and the United States still look indifferent.

Indeed, for example, in America, they really don’t care. Even if the coastal areas are flooded, they still have large tracts of wasteland to use inland. With the area of ​​North America, let alone 300 million people, even 500 million or 600 million people would be more than enough.

What’s more, each state in America has its own ulterior motives.

Coastal states like Texas and Florida naturally want to respond proactively; but those inland states and California, which has a relatively high terrain, don’t care and are even secretly creating obstacles, hoping to take the opportunity to attack the states along the southeastern coast.

Faced with this great force of nature and the intrigues, America’s decline is inevitable.
