Static sounding type deep soil sampler
The invention provides a soil sampler which can take out a soil sample buried in the deep underground rapidly and is combined with a static sounding injection device under the condition that hole drilling is not carried out. A static sounding type deep soil sampler comprises a shell (6), a sampling barrel (8), a soil expanding cone head (10), a main bearing shaft (4), an elastic ring (9), a steel piece (5), an unlocking component and other structures. The main bearing shaft (4) is provided with an annular limiting groove (12). A self-locking mechanism is formed by the annular limiting groove (12), the steel piece (5) and the elastic ring (9). The soil sampler is suitable for soft soil, generalized clay, floury soil and non-density sandy soil. Compared with traditional hole drilling and sampling, the static sounding type deep soil sampler has the advantages of being simple in structure, convenient to use, rapid, labor-saved and low in cost. The disturbance on the soil sample by the water pressure is greatly lowered when working is carried out below the underground water level, and the soil sampling success rate and the quality of the soil sample can be increased.
