The engineering team used 24-hour batch construction in batches. After three days of mining, two-thirds of the trees and plants on the entire island were leveled, and countless pieces of wood were thrown into the garbage ship as waste. The center of the island A lot of open space appeared.

In these three days, the freighter was not idle, more materials were transported to the island, a simple dock was built, a large crane lifted back and forth, and boxes of stamped steel plates passed through the Caribbean Sea and were transported to the beach.

The construction efficiency of the clone engineering team was extremely fast. On the tenth day of construction of Stellar Island, the foundation of the human freezer was dug out.

The depth of the foundation is forty meters, which is still circular, and the bottom area is 50,000 square meters. The deeper the structure, the more able to resist natural disasters such as tsunami and hurricane.

In Zhang Heng's plan, the structure of the human freezing center is made of special steel, even the underground structure. It's like building blocks. It only needs to be set up and welded. In the case of five cranes working at the same time, it took two days to lay a thick steel plate on the ground floor depth of 40 meters. , But in the center of the foundation, there is a circular blank with a diameter of 30 meters.

This circular blank part is not intended to place Yuehua. After the foundation was laid, I did not know whether it was intentional or not. The engineering team suddenly suspended the construction of the foundation, and covered a huge curtain on the foundation to cover this huge deep pit.

At this moment, in the deep pit of the foundation, Zhang Heng and the person in charge of the clone engineering team nodded, and then suddenly disappeared, and went to the radiation plane again. When he returned 24 hours later, there was more in front of him. A huge cylindrical machine with a diameter of ten meters and a length of five meters!

If anyone who has dealt with tunnel engineering all year round, when I see this machine, I'm afraid I can recognize it at a glance-this is a full-section tunnel boring machine!

The full-section tunnel boring machine is a combination of a rotary cutter head and a hob, which specializes in digging a tunnel in mountain rock formations by rotating extrusion to cut soil and rock. It is generally abbreviated as 'tbm' in foreign countries. Huaxia calls this machine a 'shield machine' because its drill bit is like a circular shield.

Obviously, Zhang Heng was going to use this tunnel boring machine to dig a secret base under the ground.

Compared with the use of drilling and other methods, the digging speed of the tunnel boring machine is several times the conventional drilling speed, the maximum daily drilling depth can reach 500 meters; it has the advantages of fast, safe, economical, and small interference to rock formations. The tunnel boring machine is an advanced machine taken from the radiation plane, which has faster efficiency and speed and higher safety.

The huge volume of ten meters in diameter means that the diameter of the tunnel it digs is more than ten meters, and this roadheader uses extrusion tunneling, so there will be no excavated soil, and the machine will open up directly at the ground. In one passage, all the dirt will be squeezed around and become extremely dense.

Based on the working efficiency of the tunnel boring machine, which is about one hundred years more advanced than reality, a tunnel can be drilled on the Stellar Island to a depth of several kilometers.

That's right, this is the third secret base Zhang Heng is going to build besides the clone production center and the hive. This base will be many times more secretive than the hive!

Because in the design, the location of this base will be located inside the Caribbean seabed rock formations, at a depth of two kilometers. In this case, even if there is a huge irreparable disaster in the world, such as the outbreak of sunspots, nuclear war, and so on, it will not affect this thousands of meters of seabed base unless the earth is destroyed.

As for the so-called subsea base structure, Zhang Heng is designed to be spherical, which is also the most resistant to crustal extrusion. Zhang Heng wants the base to not damage the subsea base even if it encounters crustal movement.

As for the soil excavated from the ground, Zhang Heng also has a solution. He directly transported the last molecular conveyor of the radiation plane here, and then connected the hive and the Stellar Island to directly transport the excavated soil there. The solution was perfect. Efficiency issues and dangers discovered.

When the full-section tunnel boring machine was drilling towards the ground, the human body freezing center on the ground also continued to work, and the ground surface works obscured the huge movements on the ground. Even if some curiosity travellers drove the boat to the side of the island to observe it secretly, It is impossible to notice that under the construction site of this island, there is still a secret that shocks the world!

Time has passed slowly, the old years have passed, Zhang Heng ’s plane has reached a new year, and the development and transformation of Stellar Island has also entered a steady period. The surface can be completed in three or four months, but it may also need to be underground Longer.

However, these are not big problems. There are guards of the Clone Corps, and Zhang Heng does not need to continue to stay here. At the beginning of the new year and January, he received a call from Yuehua again.

"Hello Commander, the good news is that the US fda has officially announced that‘ anti-freezing nano-medicine ’has passed clinical trials and new drug applications and has reached certification standards. You can already make anti-freezing agents.”

"Very well, those consortiums are really quick to work out. If they are placed in normal times, it will take at least two to three years for the antifreeze to pass the application, right?" Zhang Hengsong breathed.

"Yes, without Williams and other US consortiums putting pressure on the authorities, antifreeze is expected to take about five years to pass the application. Unlike now, certification is only six months away, ten times faster." Yuehua excited.

"It seems that the cryonics center in India is ready to open. Yuehua, you specifically selected a public relations team from the company. I need to distribute advertisements, especially online promotions, on a large scale throughout the world. I can buy Google and Hot search terms such as Baidu tell them about the existence of the Indian Cryonics Center and the Virgin Islands Cryonics Center! "Zhang Heng ordered.

"understand."

"Also, the company's pharmaceutical factory is finished. Can we start manufacturing antifreeze?"

"My Excellency Commander, I'm afraid it's not yet possible." Yuehua suddenly felt a little bit frightened. "We have already obtained the international gmp certification certificate and also passed the certification of the provincial drug regulatory bureau, but because we are injectables, we must also pass. National-level certification is considered to be qualified, but the country has been slow to let us pass the certification on the grounds that our factory has quality problems and refused to issue us a 'drug manufacturing enterprise license'. "

Zhang Hengwen said that he suddenly looked cold, "Since this is the case, we are not forcing ourselves to buy a pharmaceutical factory in India directly. We must start the production of antifreeze before the end of the month!"

"But what about Huaxia?" Yuehua was a pity. "If it is impossible to start a large-scale pharmaceutical factory with an investment of 300 million US dollars, wouldn't it be a pity?"

"Sooner or later this matter will be resolved, but not now, all we have to do now is to open the cryonics center as quickly as possible." Zhang Heng said, "The sooner it is opened, the better for us."

"understand."

After telling Yuehua, Zhang Heng silently hung up the phone, frowned suddenly, and murmured, "Sure enough, because the antifreeze has not been reviewed in the country, has the country been dissatisfied with me?" (To be continued) .) 2k novel reading network
