Chapter 1547: Super Project (Part 2)

"The area of ​​Huangyan Island is about 130 square kilometers. My initial idea is to fill up about 100 square kilometers of land. The southeast part of the island that connects to the external waterway retains a deep-water inner port of about 20 square kilometers. The inner port requires large-scale berthing. Ships; build an artificial lake with a surface area of ​​about 10 square kilometers in the middle of the island, which is used to store freshwater resources; after completion, Huangyan Island needs to have the capacity to accommodate a permanent population of 300,000 people, and the island needs to plant trees to prevent wind disasters The island does not develop a high-pollution, high-energy-consuming industrial system, and focuses on high-tech agriculture, fishery and tourism. The development plan of high-tech agriculture is to grow tropical high-yield fruits and vegetables for self-sufficiency; at the same time, take advantage of the surrounding geographical location. Develop near and far sea fishing and fishery processing industries; the tourism industry needs to have the capacity to receive 5 million tourists annually. If these goals are achieved, Huangyan Island will become an island of gold and silver, a new economic growth point for Qiongzhou Province ."
Tan Zhenhua’s laser pointer drew a circle around the map of Huangyan Island and said:
Huangyan Island is surrounded by an annular reef disk between 0.5 meters and 3 meters above the water surface. The circumference of the reef disk is 55 kilometers long, and the area is 150. Square kilometers, the shape of the reef plate is an isosceles right triangle, and a lagoon with an area of ​​130 square kilometers and a water depth of 10-20 meters is formed inside. Huangyan Island is developed in a 3,500-meter-deep sea basin and is a huge on the deep sea plain. The part of the submarine mountain peak above the water. At the southeast end of the lagoon, there is a 400-meter-wide channel connected to the open sea. This waterway is 9-11 meters deep and 360-400 meters wide. It is the only waterway connecting the island and the outside. Based on this landform, I imagine The general steps of the construction plan are as follows:
First, build a permanent wave breaker with an altitude of 5-10 meters along the ring reef with a water depth of 0.5 to 3 meters, and temporarily close the waterway.
2. Drain the sea water from the dam;
Based on 130 square kilometers and an average water depth of 15 meters, there are about 1.95 billion cubic meters of sea water. Considering that there are sea breeze in various directions in the South China Sea every day, the windmill power generation drainage method used when the Helan encloses the sea to build land can be considered.
3. After the water is drained, excavate the soil in the lagoon;
The total land area is 100 square kilometers, and the design altitude is 5 meters. Based on the current average water depth of 15 meters, the height of the filling is 20 meters, which means that about 2 billion cubic meters of earth and rock will be filled. These earthwork can be taken from the planned port of 20 square kilometers in the southeast and the artificial lake of 10 square kilometers in the middle. Based on the area of ​​30 square kilometers, approximately 67 meters of earth and stone will be excavated. In the process of digging and filling, some necessary underground facilities can be easily constructed.
After the excavation and filling work is completed, you can see the general outline of the new Huangyan Island: 100 square kilometers of land area with an average elevation of 5 meters, in the middle is an artificial lake with an area of ​​10 square kilometers and a depth of about 87 meters, the southeast of the island is a An internal port with an area of ​​20 square kilometers and a water depth of 82 meters.
Fourth, strengthen hardened ports and artificial lake dams and bottoms, build docks, airports and living and residential facilities. Some soil was transported from the mainland and spread on necessary places to improve the soil on the island, plant trees, reclaim arable land, and grow food, fruits and vegetables.
5. After the above work is completed, the dam of the southeast port can be blasted, which is the exit of the previous lagoon. After the seawater fills the inner port, the channel is dredged and the water depth of the channel is dredged to 30 meters, which can satisfy the entrance and exit of the Cape of Good Hope. At the same time, a ship lock is set up at the entrance of the passage to manage the entry and exit of ships. Taking an area of ​​20 square kilometers and a deep-water inner port of 82 meters deep, it is enough to meet the berthing requirements of hundreds of giant ships, and a part of the water can be set aside to develop mariculture. The inner harbor is not affected by the open sea, and no matter how big the waves outside are, it is still calm here, so Huangyan Island can serve as a haven for freighters and ocean-going fishing boats.
Here, I need to specifically explain the supply of fresh water on the island: the South China Sea has a tropical oceanic climate. According to the historical climate records of Huangyan Island, the annual rainfall in the waters around the island is about 1500~2000 mm, which is equivalent to per square meter. The rice area can drop 1.5 to 2 tons of rain a year. Even with a precipitation of 1500 mm, as long as the 100 square kilometers of land area of ​​New Huangyan Island and the 10 square kilometers of freshwater lake are all collected in the artificial lake during the construction of the island, there will be 165 million tons of fresh water in that year. This amount of water is enough for 1 million people to use for a year. The artificial lake in the center of the island has a depth of 87 meters and a surface area of ​​10 square kilometers. It can store about 870 million tons of fresh water. Under normal circumstances, it can be filled in about six or seven years. In addition, I also plan to build two seawater desalination plants with a daily output of 1,000 tons on the island for system redundancy and emergency purposes. "
Here we need to explain the origin of the seawater desalination device that Tan Zhenhua said-this thing was not on his investment list, but in Ningdu, he invested in a national-level polymer microporous membrane laboratory, by the former president of Beijing University of Chemical Technology Chaired by Chen Jianyuan, the initial task of this laboratory was to break through the technical difficulties of lithium membranes. After so many years of hard work and research, lithium membranes have been able to achieve mass production. At the same time, the laboratory has also developed another polymer micropore. The research direction of the membrane-RO reverse osmosis membrane. This membrane is the most basic and core material of the "reverse osmosis method" among the three major technological directions of seawater desalination. China has not been able to make domestically produced in the past, so this breakthrough is also complete. It can be said to be an important achievement to fill the gap in Huaxia's science and technology, because the successful development of reverse osmosis membranes indicates that Huaxia has finally solved one of the most important technical problems in the field of sewage purification and desalination.
The news of the successful development of reverse osmosis membranes immediately attracted the attention of China’s business community, which was already very active at this time, and soon some companies launched a series of products on this basis, from large-scale desalination plants to medium-sized urban sewage treatment systems Even small units and personal water purifiers have enterprises involved, and soon opened up the international market-this is also normal, right? The cost advantage of Huaxia's products is beyond the reach of Western companies that have always used technology monopoly as a means to obtain high profits.
So this time Tan Zhenhua only needs to put forward technical requirements, be a party A steadfastly, and purchase directly on the market.
And this also prompted Tan Zhenhua to make an important decision: "Matrix" laboratory will focus more and more on the most basic theories and core basic materials in the future, and leave the stage of engineering application to the Domestic enterprises that are booming.
This decision was endorsed by Dr. Yang Zhensuo, the director of the laboratory. At the same time, the "Matrix Laboratory Global Headquarters Park" also broke ground in the Steel Wire Bay in the southern part of Xiangjiang River. In the plan, it will be built into an integrated scientific research center, With a large-scale complex of administrative offices, residences, hotels, retail and entertainment facilities, Xiangjiang will also become one of the world's technological centers.
The reason for this decision is that the "Matrix" laboratory has a large number of senior scientific researchers with rice nationality, and Xiangjiang is their most accepted oriental city.
After Tan Zhenhua introduced the overall idea, the audience naturally burst into applause. Lin Yichong stood up and said: "For Dr. Tan’s magnificent idea, our company has also organized forces to make corresponding preparations in recent years. Let me briefly introduce the preliminary budget for the implementation of the project we have demonstrated."
This is the intention to ask for money.
