The unearthed cultural relics, particularly the unearthed cultural relics in the marine stratum are usually wrapped by the viscous cultural relic soil, and the extraction of the unearthed cultural relics, particularly the fragile cultural relics wrapped by the viscous soil is a very difficult problem.
Extraction of fragile cultural relics in the cohesive site soil requires effective dispersion of the cohesive soil. Different methods are available for soil dispersion, but the dispersion of the cohesive soil containing fragile cultural relics must be carried out in a mild mode, and the dispersion cannot be carried out in a strong acid, strong alkali, strong oxidizing property and boiling mode, so that the irreversible damage to the fragile cultural relics is avoided.
The cohesive soil has the characteristics of high content of silt and clay, high water content, poor permeability, large porosity ratio and the like. Under the same condition of soil water content, salt content is higher, and soil is stickier, and it is poor that sticky soil ventilates, the water permeability, and water retention can be strong, and this type of soil texture is stickier, has sticky when wet, the characteristics hard when dry. These soils exist in the form of aggregates of soils, 22750, which are formed by the cementation of soil particles by inorganic or organic substances.
For cohesive soils with relatively poor organic matter, the carbonates are leached and the agglomerates contain a large amount of iron aluminum oxide (R) 2 O 3 ) Belonging to the iron oxide alumina cement type.
For cohesive soil rich in the iron oxide aluminum type cementing agent, a scheme for effectively desalting and dispersing and extracting and protecting fragile cultural relics is urgently needed.

Example 1: desalination dispersion of site cohesive soil
The Jingtoushan ruins are located in Jingtoucun of pseudo-ginseng city, yuyao, nippon city, ningbo, zhejiang province, discovered in 2013, archaeological excavation is carried out from 9 to 6 months in 2019, the excavation area is 750 square meters, and ten archaeological discoveries in China are selected in 2020. The results of fourteen years of carbon and culture type comparison research show that the period of well heady mountain historical layer is about 7800-8300 years from the present, about 1000 years earlier than river-me-du culture, which is the earliest cultural relic of the era found in Ningbo areas at present and is also one of significant archaeological discoveries of Ningbo, zhejiang and even China. The wellhead mountain ruins have great value for researching marine cultural origin and marine environment transition in China, and have important reference and revelation significance for prehistoric ruins archaeological work in marine facies deposition environments in coastal areas in China.
The cultural accumulation of the wellhead site is entirely at the depth of 3-9 m below the sea level, and various scattered remains are mixed in the sticky and soft marine-phase sludge. The relics are unearthed and contain more than four hundred of various relics, and the relics mainly comprise shells of huge marine shellfish which are eaten by people and discarded, reef stones cemented with oyster shells, bones and plant seeds of various fishing and hunting animals and a large amount of artificial products. These artifacts include crockery, stoneware, bone, shellfish, woodware, braids, and the like. The braided fabric comprises mats, baskets, pack baskets and the like, is made of reed (Chinese silvergrass) and is buried in a marine silt environment. Because the degradable knitted fabric is degraded in a buried environment, the knitted fabric is seriously damaged and abnormally rotten, the site soil is heavy and is tightly attached to the knitted fabric, the knitted fabric cannot be separated, and the extraction becomes very difficult.
A small amount of viscous soil of the site is taken, dried in the shade, sieved by a 20-mesh sieve, and analyzed by an X-ray diffractometer for mineral components in a soil sample, wherein the analysis result is shown in Table 1.
From the aspect of mineral composition, the site cohesive soil sample contains a large amount of hydrous aluminum (iron) silicate structures such as montmorillonite, hydromica, kaolinite, chlorite and the like, and belongs to iron oxide alumina-cemented cohesive soil.
TABLE 1
| Cohesive soil sample | Montmorillonite% | Vermiculite% | Hydromica% | Kaolinite% | Chlorite percent | Quartz% | Feldspar% |
| 1 | 1 | 3 | 11 | 12 | 12 | 43 | 18 |
| 2 | 6 | 2 | 11 | 15 | 15 | 32 | 19 |
| 3 | 5 | 4 | 13 | 12 | 13 | 38 | 15 |
| 4 | 4 | 3 | 18 | 14 | 14 | 33 | 14 |
| 5 | 4 | 4 | 16 | 14 | 16 | 36 | 9 |
Two sets of the cohesive site soil samples were placed in 20 mesh stainless steel screens, one set was subjected to maceration, desalination and dispersion with deionized water, and one set was subjected to maceration, desalination and dispersion with 0.5% wt of a desalination and dispersion solution, and the results are shown in FIGS. 1a-1c and 2a-2c, maceration for 72h.
After the impregnation is finished, the stainless steel mesh screen is taken out, and as can be seen from fig. 1a-1c and fig. 2a-2c, the deionized water treated soil sample is only collapsed and dispersed, most of the soil sample is still in the stainless steel mesh screen, while the desalting dispersant solution treated soil sample is dispersed into finer soil particles, and only a small amount of solid remains in the stainless steel mesh screen, which indicates that the desalting dispersant can effectively disperse the cohesive soil.
After the dipping treatment is finished, the soil sample after dipping, desalting and dispersing is collected by deionized water and a desalting dispersant solution in a 20-mesh screen, dried in the shade, and sieved by taking the untreated soil sample as a reference, and deionized water is added for dipping for 24 hours, so that the content of each ion in the dipping solution of the soil sample is analyzed, and the result is shown in figure 3.
The analysis result shows that the cohesive site soil contains a large amount of salt besides the iron oxide aluminum cementing agent, wherein Na is used + 、 Ca 2+ 、SO 4 2- The content of three ions is high, especially SO 4 2- The content of the extract is most remarkable, and the highest content exceeds 2400mg/kg. The content of each ion in the soil sample treated by the deionized water is reduced, but the reduction is not obvious, which indicates that the ions are still wrapped in the soil aggregate and can not be dissolved into the solution, and the content of each ion in the soil sample impregnation liquid treated by the desalted dispersant is obviously reduced, especially the SO with the maximum content 4 2- The content of (A) is also greatly reduced, which indicates that the desalting dispersant can be sticky to the siteThe soil samples were subjected to good desalting dispersion.

Referring to fig. 4a-4f, fig. 4a-4f are pictorial representations of a consolidation extraction process of fragile cultural relics.
Select a adhesion parcel to have the well head mountain ruins stickness culture layer soil test block of fragile historical relic, consolidate the test block with the reinforcing agent, then overturn the soil test block, on will 0.5 wt desalination dispersing agent dropwise add the soil test block with the burette at room temperature, treat stickness soil test block soft back, brush gently with dipping in water pappus brush, then continue dropwise add the desalination dispersing agent, repeated operation so, the stickness culture layer soil of the fragile historical relic of adhesion parcel is clear away, overturn the fragile historical relic after will handling again, in order to clear away through reinforced surface, repeated dropwise add simultaneously or brush the desalination dispersing agent to stickness soil test block in order to get rid of the stickness soil that adheres to near reinforcing surface, wash the historical relic with deionized water, in order to be equipped with subsequent dehydration protection.
The above detailed description is provided to illustrate the present invention, but not to limit the present invention, and any modifications, equivalents, improvements, etc. made within the spirit of the present invention and the scope of the claims fall within the scope of the present invention.
