Introduction: Many countries still retain the huge stone engineering of the ancient people, and many of the stones mined are large, so how was it mined at that time, now there are various construction machinery and explosives for mining stones, and the mining speed is very fast and very easy, but it is more difficult in ancient times, and more manpower is needed.
For example, this is a house carved out of rock by the ancients, not to mention, such a stone building will not collapse or collapse for hundreds or thousands of years, unless there is a major earthquake or other natural disaster.
The ancients could generally use the materials available in nature, such as stones, wood, and hides, so working with stones became an indispensable skill.
They first use chisels and hammers to cut a row of holes in the rock, this distance is designed according to years of experience, and then take the wooden wedges and drive them in, the tighter the better, and when all the holes are driven into the wooden wedges, the workers here begin to boil water, pour hot water on the wooden wedges of each hole, and continue to do so several times, the wood wedges expand, and the boulder will crack neatly.
This is the use of stone to excavate out of the building, the ancients limited tools, can only use the most primitive methods, day by day to excavate, some projects for decades, some even generations have been working.
Summary: There are still many skills of the ancient people have been lost, there was no audio and video recording at that time, and there was no camera, and later generations can only infer the work scene at that time from the words left by the ancients, so now archaeologists are most interested in what cultural relics, that is, words, such as Sanxingdui, and now there is an urgent need to unearth Sanxingdui's words, with words, everything has an answer.
