At this time, Tarim.
A lively and noisy scene, in the entire no man’s land, became boiling.
There were sounds of digging sand everywhere, and people shouting chants everywhere.
Tens of thousands of people participated.
Commander Li Ming looked at the text message sent by Li Qi on his mobile phone, and did not immediately reply, but stood at the highest point of the canyon on both sides and looked down. Seeing that the foundation pit is already bottomless at this time, and the foundation pit no longer drops sand, because the sprayed cement has dried up.
Li Ming shouted: “Jiuquan is about to launch. How about you?”
Someone reported: “Report to the commander-in-chief. The foundation excavation of the foundation pit has now been basically completed. The second stage can be carried out.”
A hint of joy flashed across Li Ming’s face, and he shouted:
: “Start the second stage!”
“Yes!”
With an order, tens of thousands of people, “803”, used their shoulders to resist sections of steel pipes, steel bars, and iron wires from a distance.
In the construction of a foundation pit, not only is cement poured, it can become a foundation pit.
In the cement, a steel frame needs to be prepared. This steel frame is equivalent to a skeleton, which can completely pull the entire large pile of cement.
Without these steel bars, such a large cement square tuft would be shattered due to uneven force.
Because after the space cable came down, it was fixed to a point of the concrete tuft. If there is no steel frame, once the cable pulling force exceeds the load, the cement can be torn apart.
But if there is a steel frame, although it is still fixed by one point, when the bearing capacity breaks through the limit, the steel structure inside the cement will spread the force evenly to various positions, and the force will be evenly distributed.
Li Ming immediately sent a text message to Li Qi after learning the news:
“Now we have entered the weaving stage of the steel frame. The weaving time of the steel frame takes about three hours. It takes three hours to pour the cement. So we are going to perform segmented weaving and pouring.”
“That is, weave a section of steel frame and pour a section of cement. The advantage of this is that the drying speed of the cement will become faster. The combination of the two will shorten the total time. The disadvantage is that the segmented and layered pouring will cause cement blocks. The whole is not strong enough. However, under this amount of steel and cement of 1.6 million cubic meters, the weak situation is negligible. Boss, please instruct.”
“…”
Jiuquan. ,
‘Ding Dong’
In the command hall, it was already 15:29 by this time. Everyone present was holding sweat in their palms.
Li Qi’s phone rang, took out the phone and took a look at the text message above. Li Qi thought for a moment, and replied to a text message:
“Can.”
After putting down the phone, Director Li looked over and said, ‘Is the news coming from Tarim? ’
Li Qi nodded.
Director Li said: “Can they keep up with the time? Our experts have calculated that it takes about three hours for the launch rocket to reach the predetermined position. After the predetermined position, the time for the advance reverse braking is about one hour. Then. It takes another hour to fine-tune it so that it follows the corresponding point in the sky above Tarim, and rotates and follows the earth.”
“This process takes about five hours.”
“And in five hours, we will start laying the ropes. The estimated time for laying the ropes is three to four hours, depending on the actual situation. In other words, the time left for Tarim is only eight at most. Hours.”
“Can you build Tarim well? If the construction is not good, then after the cable is put down, it is likely to escape if it is not fixed in the first time.”
Li Qi was silent for a while and asked:
“If there is a tractor, will it escape?”
Director Li said in a deep voice: “Don’t underestimate the gravity from space. In fact, the gravity of other planets alone can be controlled by fine-tuning. But the cable is too long, so you can’t just consider space issues. .”
“Then what else needs to be considered?”
“The most important thing to consider is the issue of centrifugal force. The rope falls in free fall, and during this process, it will not escape. But when the rope falls, the free fall physical strength disappears, and the rope is stretched straight and there is no room to drop. At this time, because of the force of the earth’s rotation, centrifugal force will appear, and the cable will be thrown out of the earth.”
Li Qi’s eyes widened in astonishment: “Will be thrown out of the earth? That kind of power can’t be achieved by a tractor, right?”
“Yes. The tractor can only tow the rope for the first time, but in the second time, that is, when the’force’ rebounds after the free fall body strength disappears, the tractor can’t hold it 0 .. Tarim must be used. Only super-giant concrete piers are available.”
Director Li said, frowning again: “In fact, centrifugal force is only one of these. There is also a force that is very terrible…”
“What’s the power?”
“After the cable hits the ground, we also need to consider the natural forces of the earth below the atmosphere. That is-the wind factor!”
Li Qi suddenly realized, he understood now.
Actually put the cable, this is just the beginning!
The huge centrifugal force generated by the rotation of the earth;
Hurricanes tens of thousands of meters below the atmosphere;
The gravity of extraterrestrial planets;
Each of these forces is irresistible to human beings.
But now, the task of moving mountains and reclaiming the sea has become, and it is contending with these forces.
Have fun with others.
Fighting against other countries is full of joy.
But now, moving mountains and reclaiming the sea will fight against the sky and the earth.
Fun?
Pooh!
How desperate and powerless this is.
‘Boom—’
The ringing of a bell in the command hall brought Li Qi back to reality, who was lost in thought.
Immediately afterwards, a radio voice appeared throughout Jiuquan, with a plain tone and simple words.
“There are 30 seconds left before launch.”
“Attention all units.”
Li Qi suddenly squeezed his fist and looked at the large screen divided into dozens of screens.
The Chinese reporters in the command hall also nervously squeezed the equipment in their hands, focused the camera on the big screen, and held their breath.
Director Li also took a deep breath, sat on the chair, brought back his headset, and said solemnly:
“Attention all units.”
At this time, the thousands of scientific and technical personnel in the thousands of offices in the entire hall became nervous at this time, staring at the various instruments and screens in front of them.
at this moment.
All the VIP guests from the periphery also sat upright.
All foreign journalists in the periphery also pointed their cameras at Long March 5 under the blue sky.
At this moment, all the viewers in front of TV sets around the world held their breath.
At this moment, the earth stopped still.
Everyone counted in their hearts, waiting for the greatest launch in the history of this earth. none of them. .
