Description

Technical Field

[0001] The utility model relates to the technical field related to soil sampling, in particular to a sampling device for construction engineering detection. Background Art

[0002] A soil sampler is a tool used to obtain soil samples. Commonly used tools include soil augers, spades, and shovels. A soil augers consists of a hard material drill bit and a handle. The drill bit is usually spiral or cylindrical. The top of the spiral drill bit has a pair of sharp blades that rotate and cut into the soil. Immediately below the blades is an expanded cavity for collecting soil. As the handle rotates, it drills down into the soil surface, guiding the soil sample to the desired layer into the cavity.

[0003] The utility model patent with announcement number CN217765549U discloses a soil sampling device for construction engineering inspection, which belongs to the technical field related to soil sampling. It solves the problem in the existing technology that the collector is directly inserted into the soil. When collecting the soil at the bottom, the soil on the surface will be brought into the interior, causing the bottom soil to be contaminated by the outside world. It includes a soil collector body, a soil collecting mechanism, an outer pressure shell and a collection drill bit. The soil collector body includes a soil collecting mechanism, a sealing cover is movably connected to the outer surface of the soil collecting mechanism, and an outer pressure shell is movably connected to the outer surface of the soil collecting mechanism. The utility model uses the outer pressure shell to crush some relatively hard soil and rocks inside the soil through the rolling teeth when drilling, and uses the arc plate on the outer surface of the arc groove piece to repeatedly roll the surface of the soil. It has the characteristics of repeatedly rolling the surface of the soil to reduce collapse, and solves the problem that when instruments collect soil, the soil inside is relatively soft, which will cause the surrounding soil to collapse and cause damage to the original point soil, so as to achieve the effect of rolling the mud surface to prevent collapse.
