Today, more than 60 years ago, there was no advanced technology, whether mining equipment or transportation equipment, which was far from today's technology. If you want to transport such a boulder, you can only use the ancient method of rolling wood, and then use the train with the largest passenger capacity at that time to successfully bring this boulder to Beijing.
The boulder used to make the stone tablet successfully came to Beijing Square thousands of miles away by the following two methods:
The first method: Dig out huge stones made of rolling stone slabs in Fushan, Qingdao, with an initial weight of over 300 tons; Then after polishing, it lost dozens of tons. Even in this case, there are 280 tons left in the boulder.
After many times of carving and polishing, the boulder still has the weight of 103 ton. This weight is not a big project for today's large-scale mechanical equipment, but it was very difficult for people 60 years ago to transport and move.
Facing the transportation problem, people thought of the old method of rolling wood; Just facing such a heavy object, it is no longer wood, but seamless steel pipe, thus completing the transportation of huge stones to the station and the station to Beijing Square.
The second method: Although Qingdao is the nearest quarry to Beijing, it is still very difficult to transport 100 tons of boulders within this distance.
At that time, the largest heavy-haul train in China could only bear the weight of 90 tons; As a result, the boulder was polished again, and finally the weight was reduced to 94 tons, so that it was successfully used by trains and transported to Beijing.
Finally, the boulder made into a stone tablet, weighing 60 tons, was transported all the way; It not only reflects our efforts and wisdom, but also reflects our determination to overcome difficulties.
