“Its current vertical depth is around 120 meters.”
“The first stage of the underground fortress is currently excavating horizontally at this depth.”
“The device lifting set is a cage, and the equipment, personnel, and excavated stones basically go in and out of here.”
As he said that, he pointed to another similar cubic building in the distance, and introduced:
“It is an auxiliary well of the underground fortress, its depth is the same as the main well.”
“and it is primarily responsible for ventilation and drainage. of all underground work surfaces.”
Charlie nodded, and said:
“Today’s spy satellites and drones are too advanced, and ground facilities can’t even escape Google’s satellites, so underground fortifications will be a top priority in the future.”
Joseph immediately said:
“Don’t worry Mister Wade, over 65% of the infrastructure budget is currently allocated to the underground fortress.”
“In the future, the underground fortress will not only meet the needs of all the personnel and storage materials, but also shoulder Most of the daily training needs.”
“We will build secure energy storage and back-up energy systems underground, sufficient to deal with most emergencies.”
While talking, the lifting device under the cubic building lifted a large square steel cage.
Interestingly, this steel cage has two layers, the top layer for humans, and the bottom layer for the rail mining car.
After the steel cage completely stopped, more than a dozen helmeted men standing upstairs came out and walked from the second floor to the first floor.
The workers waiting on the first floor walked directly into the steel cage downstairs, setting traction ropes on the mine carts filled with gravel.
Then pulled the mine cart along the track to the loading yard hundreds of meters away.
Meanwhile, at one end, workers pushed an empty mining car into a steel cage.
Next, the entire steel cage was lowered back down to the ground.
After witnessing the whole process, Charlie couldn’t help frowning and said:
“Joseph, rely on this kind of cage to transport people and materials straight up and down.”
Isn’t the turnover efficiency too low?”
“This time, dozens of people can get on and off at most, or a few tons of stuff.”
“Even if it takes a few minutes, the efficiency is not enough in an emergency.”
Joseph hurriedly said:
“Mr. Wade, you are right.”
“The current two shafts are actually an under-construction configuration.”
“Now the underground construction is just in its early stages, so these two shafts are used for underground construction;”
“However, at a later stage, we will build a hub building of more than 100,000 square meters on the west side of the airport runway.”
“Then immediately dig a two-lane road for vehicles to enter and exit. the first floor of the hub building. well;”
“The inclined shaft will lead directly from the building ground to the underground fortress.”
“Like a tunnel with a steep slope.”
“Once done, all personnel, vehicles and equipment will be on and off from here.”
“The overall rotational speed will increase geometrically.”
“The comfort is comparable to that on the ground. No difference.”
