How can Luoyang shovel judge whether there is a cemetery? For many people, is the term Luoyang shovel very familiar? It is involved in many tomb robbing TV dramas, so how can Luoyang shovel judge whether there is a cemetery?
Luoyang shovel consists of two parts, U-shaped metal body and a long handle. The shovel body is generally 5-20cm long and 20-40cm long. The length of the shovel handle is made according to the user's needs. It is said that there are more than 20 processes for making Luoyang shovel, such as billet, calcination, heat treatment, molding, grinding, etc., because if the arc is not right, the shovel cannot be brought to earth.
In fact, Luoyang shovel does not use very complex technology, and it is not a new thing to use U-tube to insert and take things. A U-shaped or round steel tube is a common tool used by southern rice bank to check the quality of rice. After inserting the rice bag, the rice grains in the bag can be taken out for sampling. This is nothing more than the use of particles compressed into the U-shaped tube after the mutual extrusion of tension, so that it can not be moved in the tube.
A good Luoyang shovel requires a sharp and hard blade, even if the stone and other objects in the shovel do not roll the blade gap. The shovel body should have certain toughness, so that it is not easy to break. A good Luoyang shovel can insert into the soil and eat it sharp. It can quickly remove the soil after pulling it out. And can break through and extract broken brick thick tile. In the past, such Luoyang shovels were all made by hand. In addition to the need to use good steel forging, the cutting edge should be specially heat treated to increase the hardness.
For tomb robbers, the main function of Luoyang shovel is to locate the holes. An experienced tomb robber can analyze whether there is a tomb underground through the soil brought out by Luoyang shovel. If you drill several holes in one area, you can know the approximate location and area of the tomb, so as to know the scale and value of the treasures in the tomb. Experienced tomb robbers can judge the underground situation even by the sound and feel of Luoyang shovel colliding with the underground. The feeling of the rammed wall is different from that of the hollow tomb chamber and the tomb path. The experienced tomb robbers can accurately determine the structure of the tomb and determine the fastest and easiest way to dig into the tomb from that location.
When robbing a tomb, the thief will first look at the terrain. If he suspects that there is a tomb in the area, he will use Luoyang shovel to explore the road. He will dig a hole on the left and right to explore. Generally, if he feels hard after 3-5 meters, he will continue to dig. If he feels soft, it means that it is not a tomb. He will dig in another place. Generally, it takes about 20 minutes to dig a 5-meter exploratory hole. Experienced grave robbers will avoid the tomb path, and constantly use the exploratory hole to find the tomb -- because there are many mechanisms or access control in the tomb path to prevent people from robbing the tomb, and it is easier and safer to enter directly from the top of the tomb vertically.
When using Luoyang shovel to explore the hole, the user should stand up straight, stick a horse with two feet, hold the shovel bar with both hands, and drill down vertically. In the process of drilling, the shovel head shall be continuously rotated, and the probe hole shall be kept circular, otherwise, it cannot be deepened and pulled out. If the probe hole is not bent or crooked, it will be the most labor-saving and direct visual inspection of the hole. Tomb robbers often use a mirror to reflect sunlight and look down from the hole opening if they can see the bottom of the hole. If they can't, they need to drill again.
