Abstract

The invention discloses a piston type fixed-depth soil core sampling device and a use method thereof, relates to a soil core sampling device and a use method thereof, and aims to solve the problems that a conventional soil sampling device difficultly excavates and takes out fixed-length undisturbed soil from a drill body and the sampling error is outstanding. The piston type fixed-depth soil core sampling device comprises a drilling shank, a push rod clamping slot, a piston push rod, a piston, a drilling bit and drilling bit saw teeth. The use method comprises the following steps: 1, clamping a clamping shank of the piston push rod to the push rod clamping slot correspondingly according to a sampling depth; 2, vertically placing the piston type fixed-depth soil core sampling device at a point position to be sampled; 3, starting the drilling bit saw teeth, and plugging the piston type fixed-depth soil core sampling device into the soil at the point to be sampled to reach the sampling depth; and 4, taking out the piston type fixed-depth soil core sampling device, putting on the ground flatly, and cutting off layer by layer with a tool, thus completing fixed-depth soil core sampling. The piston type fixed-depth soil core sampling device is mainly used for collecting soil.

Description

technical field [0001] The invention relates to a soil core sampling device and a using method thereof. Background technique [0002] Soil sampling is one of the important basic tasks for scientific and technological workers engaged in environmental and ecological research. Accurate and quantitative collection of soil or sediment at different depths is directly related to the accuracy of related research and the reliability of data. The length of the sampling drill body of a general soil sampling device is fixed, so only soil cores of the same length can be accurately collected, and it is difficult to collect soil cores of different depths with one soil sampling device as required. In addition, after the soil core enters the sampling drill body, due to the negative pressure in the drill body and the friction between the soil core and the inner wall of the drill body, it is difficult to remove the soil core from the drill body smoothly. Pulling out forcibly will often lead t...
