Description
Technical Field
The invention relates to a test soil sample collecting device, in particular to a self-closing luminescence test soil sample collecting device and a self-closing luminescence test soil sample collecting method.
Background
The geologic age is a unit of time that is used geologically to describe the earth's historical events, and generally includes two implications: the first is the sequence of occurrence of each geological event, and the second is the age of each geological event. The accurate determination of geologic age is the basis for complete knowledge of geologic events and the evolution history of the earth and crust.
In the research of geological environment and geological disasters, the evolution history of deep cutting valleys in the three rivers parallel flow region in the south of the west of China is closely related to the development characteristics of geological disasters (landslide for blocking the river bodies and debris flow for blocking the river bodies). Therefore, it is necessary to study the mechanism of landform evolution and river valley development by determining the development history of geological disasters.
When a landslide or a debris flow blocks a river, the sliding belt material or the accumulated material is subjected to high-temperature heat baking or sun exposure, and the age of the occurrence of the sliding belt material or the accumulated material can be determined by measuring the time after the sample is subjected to the high-temperature heat baking or the sun exposure. Therefore, the two geological dating methods of thermoluminescence and photoluminescent photoluminescence are gradually combined to be applied to the age determination of the river-plugging body.
The thermoluminescence geological dating method requires that the soil sample cannot be heated when collected, and the thermoluminescence geological dating method requires that the soil sample cannot be exposed when collected. If the requirements cannot be strictly followed when collecting the luminescence test soil sample, the wrong geological age can be measured, so that higher standards are provided for methods and tools for collecting soil samples. However, the existing soil sample collecting tool cannot meet the requirements of no heating and no exposure of the soil sample. Therefore, it is necessary to invent a collecting device and a testing method suitable for thermoluminescent and photoluminescent soil samples.
