Non-disturbance soil sampler and sampling method thereof
Technical Field
The invention relates to the technical field of soil sampling, in particular to a non-disturbance soil sampler and a sampling method thereof.
Background
The soil is a complex system composed of three-phase substances of gas, liquid and solid, and a framework composed of solid particles of the soil is filled with air, water and different salts. The soil has the characteristics of an electrolyte solution due to the presence of water and salts capable of conducting ionic conduction, and solid particles of the soil contain sand, ash, sludge and humus soil formed after the plants are rotten.
Most soils are a collection of mixed inorganic and organic colloidal particles, which also have many tortuous capillary pores through which water and air in the soil can pass to reach the depth of the soil. Some of the water in the soil is associated with soil constituents, some of which adhere tightly to the periphery of the solid particles and some of which may flow in the micropores. The salts dissolve in this water and the soil becomes the electrolyte. The conductivity of soil is related to the moisture and salt content of soil. Some oxygen in soil is dissolved in water and some oxygen is stored in capillary micropores and gaps of soil, the content of oxygen in soil is closely related to the humidity and the structure of soil, various microorganisms exist in soil, and bacteria which have corrosive effect on metals can exist in soil, so that the property of soil is complex. Because of the relative immobility of the solid components constituting the soil, unlike the fluidity of the atmosphere and seawater, the physical and chemical properties of the soil are not the same even in the same type of soil.
The soil physicochemical property plays an important role in the fields of agriculture, electric power, petrochemical industry, buildings and the like, and the accurate detection and monitoring of the soil physicochemical property have a key significance on plant growth, material design, maintenance and the like in the fields. Regarding the soil corrosivity parameter, the corrosivity of the soil is closely related to the original state of the soil.
At present, a cutting ring and the like are generally adopted to cut into soil for non-disturbance sampling of soil, so that the soil is difficult to be not disturbed during sampling, and the cutting ring can also cause damage to the soil structure when a soil sample is removed; in addition, when a soil sample is taken out of the cutting ring and put into a soil physical and chemical parameter detector, the integrity of the original structure of the soil cannot be ensured, so that the non-disturbance soil sampler and the sampling method thereof are provided to solve the problems.
