Soil layered sampling fixing device and method

[0018] Specific implementation mode one: combine Figure 1 to Figure 4 Describe this embodiment mode, a kind of soil stratified sampling fixing device described in this embodiment mode comprises inserting piece 1 and fixing plate 2, fixing plate 1 is a strip-shaped plate body, and one end of inserting piece 1 is connected with one end of fixing plate 2 to form One body, and the insert 1 and the fixed plate 2 form an L-shaped plate body, and the front of the fixed plate 2 is provided with multiple ring knife fixing grooves 2-1 along the length direction, and the ring knife fixing grooves 2-1 and the insert 1 are located on the same side . The insert 1 is used to fix the soil surface.

[0019] Specific implementation mode two: combination Figure 1 to Figure 4 To illustrate this embodiment, a scale 3 is marked on the back of the fixing plate 2 of the fixed device for stratified soil sampling described in this embodiment along the length direction. The function of the scale 3 is to mark the position of the ring cutter, so as not to aim at the force point when beating hard on the soil layer, and destroy the sampling device. Other components and connection relations are the same as in the first embodiment.

[0020] Specific implementation mode three: combination Figure 1 to Figure 4 To illustrate this embodiment, each ring knife fixing groove 2-1 of a soil stratified sampling and fixing device described in this embodiment is a circular groove with a diameter of 5.046 cm. Other components and connections are the same as those in the first embodiment.
