Soil sampling device for engineering investigation

The utility model discloses a soil sampling device for engineering investigation, which comprises soil sampling equipment, two sides of the bottom of the soil sampling equipment are connected with guide devices, and the bottoms of the guide devices are connected with moving devices. According to the soil taking device, the soil taking cylinder can be more conveniently screwed into soil through rotation, soil taking of the soil taking cylinder is facilitated, after soil taking is completed, soil in the soil taking cavity is downwards pushed out by pushing the push plate, soil attached to the interior of the soil taking cylinder can be conveniently taken out, and the soil taking device is more convenient to use and higher in practicability. The soil sampling barrel can be ensured to be vertical when moving up and down through the guide device, so that the soil sampling barrel can be screwed out of soil after being screwed into the soil, and the soil sampling is smoother; and by arranging the moving device, the
