Abstract

[목적] 지중에 타입 또는 천공갱에 삽입한 강관제 또는 콘크리트제 말뚝의 시공품질을 확인할 수 있는 장치로 유압잭을 가진 말뚝 이 말뚝으로 시공품질을 확인하는 방법을 제공하기 위한 것이다.[Purpose] It is a device that can confirm the construction quality of steel pipe or concrete pile inserted into underground or drill pit. It is to provide a method of confirming construction quality with pile with hydraulic jack.

[구성] 지름이 20~30mm인 램(3)을 가진 유압잭(2)을 콘크리트 말뚝(1)의 선단 또는 강관 말뚝(6)의 선단에 내부에 매설 또는 부착하고, 유압잭(2)의 실린더에 지상까지 당도할 수 있는 길이의 유압관(4)을 말뚝(1,6)에 매설 또는 부착한 것을 특징으로 하는 시공품질확인용 유압잭을 가진 말뚝과, 상기한 말뚝을 항타 또는 천공갱에 삽입하고 지상에서 유압관을 통해 유압을 가하여 유압토출량을 일정한 값으로 유지하여 램의 변위량을 관측하고, 그 때의 하중과 변위량을 근거로 하중-변위량 관계를 작성하여 말뚝의 시공품질을 확인하는 방법이다.[Configuration] A hydraulic jack 2 having a ram 3 having a diameter of 20 to 30 mm is embedded or attached to the front end of the concrete pile 1 or the end of the steel pipe pile 6 and attached to the cylinder of the hydraulic jack 2. The pile having a hydraulic jack for construction quality checking, characterized in that it is embedded or attached to the pile (1,6) and the hydraulic pipe (4) of the length that can reach the ground, and insert the pile into the driving or drilling pit It is a method to check the construction quality of the pile by applying the hydraulic pressure through the hydraulic pipe on the ground to maintain the displacement of the ram to maintain a constant value, and create a load-displacement relationship based on the load and the displacement at that time.
