Static sounding type deep soil samplers
The invention provides two static sounding type deep soil samplers. According to each static sounding type deep soil sampler, a main force bearing shaft is arranged inside a cylinder structure composed of a shell, a sampling tube and a tube shoe, the lower end of the main force bearing shaft is connected with a soil expanding cone head, a steel sheet and an electric ring are arranged between the main force bearing shaft and the shell, and the steel sheet and the elastic ring are clamped in an annular groove. According to the first static sounding type deep soil sampler, the annular groove is formed in the inner surface of the shell, an annular limiting groove is formed in the main force bearing shaft, and the main force bearing shaft is sleeved with an unlocking component composed of a thin-walled pipe and a control bar. According to the second static sounding type deep soil sampler, the annular groove is formed in the main force bearing shaft, an annular limiting groove is formed in the inner surface of the shell, and the main force bearing shaft is sleeved with a thin-walled pipe serving as an unlocking component. The two static sounding type deep soil samplers are used in combination with static sounding penetration equipment, a soil sample buried deep underground can be taken out rapidly under the condition that drilling is not needed; the static sounding type deep soil samplers have the advantages of being simple in structure, convenient and fast to use, capable of saving labor and low in cost; the disturbance of the water pressure on the soil sample can be reduced.
