How to retrieve the cultural relic
There were many rigorous steps to take out the cultural relics. The following were the methods to take out the cultural relics in different scenarios: ** 1. Take out the archaeological relics on land ** 1. ** Archeological Investigation ** - Under the condition of not destroying the current situation of the site, they should carry out field inspection or exploration on the surface of the site, focusing on investigating the ditches, ridges, terrace sections, river terraces, riverbank highlands and other areas of farmland, as well as places with possible stories such as "Wangfen Gully" and "Chengzi Village" to discover ancient remains. - Collect distinctive and representative specimens that can reflect the patterns, texture, shape, age, and key parts of the artifacts in order to determine the location of the remains. 2. ** Archeological Exploration ** - With the help of a shovel and various technological means. They often used drilling and geological exploration methods. Geophysical exploration used geological exploration techniques to detect underground relics and often cooperated with drilling. They first explored a large area and then drilled in abnormal areas. - The method of arranging holes when digging the shovel included plum blossom point method, cross method, well method, one word method, etc. According to the soil brought out by the shovel (such as lime soil, five-flower soil, rammed soil), the nature of the relic was judged, and it was found that there might be a tomb underground. 3. ** Archeological excavation (approved by the Cultural Relics Administration Department)** - Make preparations, such as applying for an excavation permit, formulating an excavation plan, preparing a budget, organizing a team, preparing tools, and so on. - Use the method of exploration or trench excavation. Taking the site excavation as an example, the excavation area was divided into exploration areas according to the quadrants method.(Generally, it is 5m × 5m or 10m × 10m, composed of the main body, partition beams and key pillars). A 1m partition beam is left in the east and north of each exploration party to control the stratum and progress, as well as the transportation and walking passage. During excavation, the cultural layer and the range of relics are divided according to the soil quality, soil color and the contents. The principle of exposing layer by layer is followed. The flat and profile are combined to control the change of stratum. The exploration party unifies the progress. The relics are collected strictly according to the stratum and the unearthed unit, and the unearthed location is recorded. Collect artificial relics, human remains, animal bones and other natural relics (plant remains, mollusc remains and small animal remains in the shell hill site), and collect or extract important relics or traces. - When collecting relics and samples, fill in two copies of labels according to the number of the relics and stacking units, and seal them in plastic bags. The collection tools should be clean, and the staff should wear gloves. ** 2. Take out the deep-sea archaeological relics ** 1. ** Deep-sea archaeological relics from the shipwreck site on the northwest slope of the South China Sea (such as the No. 1 and No. 2 shipwreck site on the northwest slope of the South China Sea)** - A variety of deep-sea techniques and equipment were used to extract cultural relics through the flexible robotic arm of the submarine. Because it was impossible to extract cultural relics directly by hand through divers in the deep sea, the flexible material robotic hand would not damage the surface of the cultural relics, and it had enough grip to collect the cultural relics and bring them back to the surface, which would then be sorted out by archaeologists. - The number of cultural relics extracted was carried out according to the requirements of archaeologists. Each dive took about 8 hours, and the diving speed of the submarine was 35 meters per minute. The South China Sea shipwreck site was 1500 meters deep, and it took about 40 minutes to dive once. The round trip took about one and a half hours, and the underwater operation time was about 6 hours. 2. ** Other fragile cultural relics from the seabed (such as bamboo strips from the shipwreck site of the Yuan Dynasty in Shenglingyu, Zhangzhou, Fujian Province)** - Zhejiang University's cultural protection team used 3,4 -dimethylethylbenz [veratrolic], a temporary reinforcement material used underwater. The material needed to adapt to different temperatures, salinities, and hydraulic pressures, and explored a set of underwater environment construction methods. - Before the official seabed extraction, the experiment was carried out in a similar environment (such as the underwater archaeological training pool in Yangjiang, Guangdong Province). After success, the fragile cultural relics were extracted from the shipwreck site. Read more exciting novels for free
