Wesley introduced Charlie, “Mr. Wade, this is the main shaft of the underground fortification.
Its current vertical depth is about 120 meters. The first phase of the underground fortification is currently excavating horizontally at this depth. The set of lifting devices is the cage, and equipment, personnel, and excavated rocks basically come in and out from here.” As he said that, he pointed to another similar square building in the distance, and introduced, “That one is the auxiliary well of the underground fortification. The depth is the same as the main well and it is mainly responsible for ventilation and drainage of all underground working surfaces.”
Charlie nodded, and said, “The current spy satellites and drones are too advanced and the ground facilities can’t even escape Google’s satellites, so the underground fortifications will be the most important thing in the future.”
Wesley immediately said, “Mr. Wade can rest assured that more than 65% of the current infrastructure budget is allocated to underground fortifications. The future underground fortifications will not only meet the needs of all personnel’s life and material storage, but also shoulder most of the daily training needs. At the same time, we will build a safe energy storage and backup energy system underground, which is enough to deal with most emergencies.”
While speaking, the lifting device under the cubic building lifted a huge square steel cage up. Interestingly, this steel cage has two layers, the upper layer is for people, and the lower layer is for a rail mine car. After the steel cage came to a complete stop, more than a dozen men wearing helmets, standing on the upper floor came out of it and walked from the second floor to the first floor.
The workers waiting on the first floor walked directly into the steel cage on the bottom floor, fixed the traction rope on the mine car filled with gravel, and then pulled the mine car along the track to the loading and unloading yard hundreds of meters away. At the other end, workers pushed an empty mine car into the steel cage. Subsequently, the entire steel cage was lowered into the ground again.
After watching the whole process, Charlie couldn’t help frowning and said, “Wesley, relying on this kind of cage to transport people and materials straight up and down, isn’t the turnover efficiency too low? This time, at most dozens of people can go up and down, or a few tons of goods. Even if it takes a few minutes, the efficiency is still a drop in the bucket in an emergency.”
