The inventor of the Luoyang shovel was a local tomb robber in Luoyang. Since the beginning of the last century, the magical Luoyang shovel has caused the Mangshan area of ??Luoyang, where my country's ancient tombs have the highest concentration, to be empty, and many cultural relics have been leaked out. Luoyang Shovel gained notoriety. But everything has two sides, and the invention of Luoyang shovel is not without its good side. After the famous archaeologist Wei Juxian witnessed tomb robbers using Luoyang shovel in 1928, he used it in archaeological drilling and played an important role in the excavation of famous ancient city sites such as Yin Ruins and Yanshi Mall in my country. Nowadays, learning to use Luoyang shovel to identify soil quality is a basic skill for every archaeologist. Professor Qin saw that everyone was very interested in the Luoyang shovel, so he picked up a Luoyang shovel and explained it to everyone: "Our common Luoyang shovel has a 2-inch wide clamp, which is shaped into a U-shaped semicircle. Although the long-handled Luoyang shovel installed on the upper part looks semi-circular, the shape is actually neither round nor flat. The most important thing is to create the arc during molding. " "If a good Luoyang shovel is made, then it is installed with strong toughness. A waxwood pole is connected to a special rope, and after being installed with a flexible wooden pole, it can be driven into the ground to a depth of more than ten meters or even tens of meters. When the shovel is lifted, a tube of soil will be brought out from the inside of the shovel head. " "By continuously drilling deeper into the ground, we will analyze the soil structure, color, density and various inclusions of the different soil layers extracted. If it is Wuhua soil that has been disturbed by later generations, there may be tombs or ancient remains underground. Construction." Li Beibei tried the Luoyang shovel in her hand with great interest when she heard this. He asked curiously: "Professor Qin, what is Wuhua soil?" Professor Qin smiled and explained: "The ancients built a cave tomb. They had to dig a rectangular opening in the ground and dig down several meters. After the burial, the tomb door was sealed, the excavated natural soil scattered on the ground was filled into the tomb passage, and the natural soil was excavated and backfilled layer by layer. , disrupting the original layers and color boundaries, and turning it into a flower soil that combines multiple soil layers. This is Wuhua soil or Dahua soil. This kind of soil cannot be combined even if it is old. " "Except for Wuhua soil. In addition to flower soil, if ceramics, iron, copper, gold, and wood are found in the soil, we can infer the nature and layout of the underground collection. "In addition, some of our experienced staff can use Luoyang shovels to collide." The different sounds coming from the ground and the feeling on the hands can be used to judge the situation underground. For example, the solid walls are definitely different from the hollow tomb chambers and tomb passages.¡± After hearing Professor Qin¡¯s explanation, everyone nodded in understanding. At this time, Chu Chen observed the exploration holes on the ground. Asked: "Professor Qin, are there any specific requirements for these exploration holes? It seems to me that there are quite some rules here." Professor Qin said with a smile: "Of course there are requirements. Like us, we usually meet the requirements as needed. The size of the drilling area. Organize a certain number of drilling teams to conduct general exploration within the designated area. "The general exploration process is to drill holes every one meter regardless of the length and breadth of the ground. , forming a square grid. In addition, a hole must be drilled in the center of each square, which is commonly known as the "plum blossom point" within one square meter. , so that the nearest distance of each hole is within one meter, and the holes are intensively explored to ensure that no problems are missed. Then a technician is sent to check the suspicious holes found during the general inspection process to explore the range, diameter and edge shape of the problem. " After Professor Qin introduced the work process to everyone, he asked the staff to demonstrate the actions for everyone, so Chu Chen and Li Beibei followed the actions demonstrated by the staff with great interest and used the Luoyang shovel. But some things look easy, but in practice they are very difficult. Fortunately for Chu Chen, he had a photographic memory and a strong hands-on ability. After a few attempts, he got it right. When Professor Qin saw him, he laughed and praised him as a natural archaeologist. . On the other side, Li Beibei's performance was undoubtedly much worse. She often punched holes crookedly due to her poor posture when holding the shovel and her personal usage habits, so the staff next to her kept yelling at her. Correction was made, but even so, the hole she made was still a little crooked. She often made crooked holes, and the poor posture made her palms very painful, which made Li Beibei very discouraged. However, she saw that Chu Chen next to her was already very skilled in using it, and she was praised by Professor Qin from time to time. This made her feel very unconvinced, so she gritted her teeth and persisted. Two exploratory holes less than one meter apart, two people dug down at the same time, one vertical hole and one skewed hole. Then, at a depth of seven or eight meters, the skewed hole will intersect with the straight hole, and the two shovel heads will collide. Come together?Although this situation is rare, it is not unheard of. Especially for newbies, even if they receive guidance, this situation will still happen. The current situation is like this. I saw Chu Chen and Li Beibei shoveling down at the same time. However, Chu Chen was stronger and reached the bottom first, while Li Beibei's shovel followed closely behind. Then the two of them felt their hands shake. Chu Chen was fine when he arrived, but he felt something hit his Luoyang shovel. Li Beibei didn't expect to encounter such a thing at all. In addition, in order to catch up with Chu Chen's speed, she shot fast and hard, and because she was a novice, she already had blisters on her hands. When she reacted, the blisters on her palms were immediately scratched by the handle of the shovel, and she screamed out in pain. Everyone thought something had happened and quickly ran to Li Beibei to ask. After Professor Qin learned about the situation, he asked a female staff member to bandage Li Beibei, and then took out her Luoyang shovel. When she saw a dent in the head of the shovel, she immediately guessed what caused it. , said: "It should be that the exploration hole was drilled crookedly, and it went to Xiao Chu's side." Qi Baolin now also knew Li Beibei's stubborn temper, and said helplessly: "Li Beibei, since you can't do this, don't do it." Is it okay to show off? " Li Beibei retorted after hearing this: "Captain, I'm not trying to show off, I'm just inexperienced. If it goes by normal circumstances, I'm deeper than Chu Chen!" " Qi Baolin! Frowning, he said: "You also know that you are in an abnormal situation now, and Mr. Chu is not as embarrassed as you, right? Li Beibei, let me tell you, in our job, the most taboo thing is to do something that does not overestimate our capabilities. If you Use this method at work, and I will ask your superiors to transfer you back. " Li Beibei opened her mouth to complain when she heard what Qi Baolin said, but she thought that she was Qi Baolin's soldier after all, and she would suffer the consequences if she made the mistake. It was always herself, so she could only take back the words that came to her lips. Feeling aggrieved, Li Beibei scolded Chu Chen and vowed that when her plan was successfully implemented, she would torture Chu Chen to relieve her hatred. But thinking about the original plan, Li Beibei felt powerless again. During this period of time, she had been trying hard to show her kindness to Chu Chen, but Chu Chen refused to accept her words and only responded to her politely, which made her feel like a dog biting a hedgehog and unable to bite him. "Bah, bah, bah! I'm not a dog! But what's going on with this guy Chu Chen! Is it because I'm not charming enough? Or is he always holding a grudge because of what happened before? Isn't this possible? Is there still such a thing? A petty man? " After thinking for a while, Li Beibei couldn't think of a reason, and said to herself: "No matter, it won't be a problem if this continues. I have to find a way to deal with the relationship first, but in the end I should What method should be used? " Chu Chen didn't know that Li Beibei was racking his brains to plot against him. At this time, he was looking at the soil taken out from the cave with some excitement. "Professor Qin, come and take a look. This soil seems a little different!" Professor Qin was stunned when he heard this, and then quickly came to Chu Chen. When he saw the soil shoveled by Luoyang, his expression suddenly became happy and excited. Said: "This is fluttering soil, haha, Xiao Chu, you are so lucky!" "Plopping soil?" Chu Chen asked with some confusion: "Professor Chu, what is fluttering soil?" Professor Qin was a little excited. Explained: "Although the filling soil in the tomb passage has been rammed, its structure is not as tight and hard as the natural soil. The remaining soil that has not been filled in is scattered around the tomb passage, forming fluttering soil. It is the same as the flower soil in the tomb passage, but "It's not very thick." "Generally, after drilling and identification, the scope and depth of the original excavation of the tomb passage and chamber can be determined." After hearing Professor Qin's explanation, Chu Chen was very excited and asked, "So. "Say, is the tomb passage nearby?" Professor Qin said excitedly: "Yes, the tomb passage is definitely not far away. Xiao Liu, please explore the nearby area carefully and try to give the direction of the tomb passage as soon as possible. Found it.¡± Following Professor Qin¡¯s instructions, the staff quickly started surveying and exploring. Director Wang on the other side also became extremely excited after answering the phone call. Director Wang made this call for a full fifteen minutes. When he hung up the phone, he said to Chu Chen and others ecstatically: "Good news, good news! Captain Qi, the group of tomb robbers you came to investigate this time The thief already has news!" "Ah!" Director Wang's words made everyone stunned for a moment. When they came to their senses, Qi Baolin hurriedly asked: "Director Wang, what happened???What's going on? Please tell us the specific situation! "Everyone should have understood after seeing this that the information about the tomb robbers that Director Wang mentioned was obtained from Zhao Yiping.
