Luoyang shovel is a symbol of archaeological drilling tools in China. In the early 1970s, when an archaeological delegation from China visited Albania, it presented an exquisite Luoyang shovel. When in use, stand up straight, spread your legs apart, hold the lever with both hands, put it on your chest, shovel your head on the ground, and lie between your toes, vertical to the probe downward. Open the hole to the bottom, turn the shovel head continuously, and hit it alternately on all sides to keep the hole cylindrical. Dig down from the blade, and break it longitudinally to see the section. When you look at the soil, you can't shovel it back After hitting the ground two or three times in a row, the shovel back is lifted. There are many kinds of underground soil in Luoyang, and explorers can be roughly divided into dead soil and living soil. Generally speaking, the dead soil of 10 thousand years ago can't be found. Otherwise, you can't get down, you can't pull it out, and the shovel is stuck in the hole. While drilling, shovel the hole semicircle; Double-sided shovel, elliptical hole; Only with a shovel on all sides can the detection hole be round. The hole to be punched should be straight. Just don't bend, straight and not crooked. It is not easy to drill vertical holes. When using tools, the shovel head should be straight and the pole should be straight. Otherwise, it is easy to bend the hole, or even make a hole with a small mouth and a big belly, and it will not be famous. In order to test the vertical bending of the probe hole, you can take a mirror and shine down from the hole with the help of sunlight. When the light hits the bottom of the hole, the hole is straight. If the light does not reach the hole wall, the hole is curved, and the tool must be trimmed before drilling. It is difficult to bend the hole. When pulling the pole with both hands, you can also pull it up with your shoulders against the wooden pole.

Beginners drill holes several meters deep, and drill one or several holes, so it is easy for them to grind blisters on their palms and soon grind cocoons. This is the initial experience of learners. Beginners can play 50 cm south and 50 cm north, turn down in turn, correct the deviation of arm holding shovel, and practice drilling vertical holes. When you first come out of the hole, Luoyang shovel will go down hard, and then go down with a little force. A little deeper, people don't have to work hard. When they put down the shovel, they will hit the soil. If the novice does not receive strict training, or the shovel posture is not standard enough, as well as personal habits, there will be some deviations and crooked holes. The distance between the two detection holes is less than 1 m, and two people detect at the same time, one vertical hole and one inclined hole. Then at the depth of 8 meters, the inclined hole even intersects with the straight hole, and the two shovels touch together. Although this situation is rare, it is not uncommon.
