Referring to Figure 2, the inner tube 200 is provided with a cylindrical steel tube, inserted into the through-hole (100s) is seated on the step 110, the soil sample (M1) is collected in the inner tube (200). do.

따라서, 토양시료(M1)가 채취되는 내관(200)이 철제관으로 마련되므로, 내관(200)이 반영구적으로 사용될 수 있다. Therefore, since the inner tube 200 from which the soil sample M1 is collected is provided as an iron tube, the inner tube 200 may be used semi-permanently.

그리고, 내관(200)의 상단에는 전후방향으로 각각 돌출되는 한 쌍의 제2손잡이(210)가 마련되어, 외관(100)으로부터 내관(200)을 분리할 때, 작업자가 한 쌍의 제2손잡이(210)를 통해 외관(100)으로부터 내관(200)을 분리할 수 있다. In addition, a pair of second handles 210 protruding in the front and rear directions are provided at the upper end of the inner tube 200, and when the inner tube 200 is separated from the outer tube 100, the operator has a pair of second handles ( The inner tube 200 may be separated from the exterior 100 through 210.

밀폐부(300)는 복수개의 원형봉으로 마련되고, 외관(100)이 타격에 의해 지층(M2) 내부로 관입되어 내관(200) 내에 토양시료(M1)가 채취된 이 후, 삽입홀(100u)에 삽입되어 관통홀(100s)의 하부를 밀폐한다. The sealing part 300 is provided with a plurality of circular rods, and after the exterior 100 is penetrated into the ground layer M2 by the impact and the soil sample M1 is collected in the inner tube 200, the insertion hole 100u. ) To seal the lower portion of the through-hole (100s).

그리고, 고정부(400)는 한 쌍의 사각바로 마련되고, 밀폐부(300)가 삽입홀(100u)에 삽입된 후, 삽입홀(100u)에 삽입되어 밀폐부(300)를 가압하여 밀폐부(300)의 유동을 방지한다. In addition, the fixing part 400 is provided with a pair of square bars, and the sealing part 300 is inserted into the insertion hole 100u, and then inserted into the insertion hole 100u to press the sealing part 300 to seal the sealing part. Prevent the flow of 300.

도3을 참조하여 설명하면, 외관(100)이 타격에 의해 지층(M2) 내부로 관입되어 내관(200) 내에 토양시료(M1)가 채취된 후, 삽입홀(100u)에 복수개의 원형봉으로 마련되는 밀폐부(300)가 삽입되고, 한 쌍의 사각바로 마련된 고정부(400)가 삽입홀(100u)에 삽입되어 밀폐부(300)를 가압함으로써, 관통홀(100s)의 하부가 밀폐부(300)를 통해 밀폐되도록 하며 밀폐부(300)의 유동을 방지한다. Referring to FIG. 3, after the exterior 100 is penetrated into the strata M2 by the impact and the soil sample M1 is collected in the inner tube 200, a plurality of circular rods are inserted into the insertion hole 100u. The sealing part 300 to be provided is inserted, and the fixing part 400 provided as a pair of square bars is inserted into the insertion hole 100u to press the sealing part 300 so that the lower part of the through hole 100s is closed. It is to be sealed through the 300 and prevent the flow of the sealing unit 300.

따라서, 외관(100)의 인양시, 관통홀(100s)의 하부가 밀폐부(300) 및 고정부(400)에 의해 밀폐되므로, 내관(200) 내의 토양시료(M1)가 하측으로 흘러내리는 것이 방지되므로, 정확한 퇴적물의 지층(M2)을 확인할 수 있게 된다. Therefore, when the exterior 100 is lifted, since the lower portion of the through hole 100s is sealed by the sealing part 300 and the fixing part 400, it is possible that the soil sample M1 in the inner tube 200 flows downward. Since it is prevented, it is possible to confirm the exact layer M2 of the deposit.

결과적으로, 본 발명에 따른 철제관으로 마련되는 내관을 이용한 반영구적 토양시료 채취기(10)는 토양시료(M1) 채취 후 토양시료(M1)를 지상으로 인양할 때, 밀폐부(300) 및 고정부(400)를 통해 토양시료(M1)가 하측으로 흘러내리는 것을 방지하여 정확한 퇴적물의 지층(M2)을 확인할 수 있는 효과가 있다. As a result, the semi-permanent soil sample collector 10 using the inner pipe provided with the steel pipe according to the present invention, when the soil sample (M1) to lift the soil sample (M1) to the ground, the sealing portion 300 and the fixed portion Through 400, the soil sample (M1) is prevented from flowing down to have the effect of confirming the exact layer of sediment (M2).

그리고, 토양시료(M1)가 채취되는 내관(200)이 철제관으로 마련되어 반영구적으로 사용될 수 있다. In addition, the inner tube 200 from which the soil sample M1 is collected may be used as a steel pipe semi-permanently.
