Zusammenfassung:The present invention relates to a height adjusting device of a cover for an underground-buried inspection hole. More specifically, a height adjusting shaft is formed inside a height adjusting device of a cover for an underground-buried inspection hole to be vertically movable by rotation. Accordingly, an operation of adjusting the height of the height adjusting device of a cover for an underground-buried inspection hole from the ground can be quickly and easily conducted, and the time and labor force required for installation and construction thereof can be reduced. In addition, the height adjusting shaft inside the height adjusting device of a cover for an underground-buried inspection hole is used to precisely adjust the height of the height adjusting device of a cover for an underground-buried inspection hole from the ground. Moreover, since the height adjusting shafts provided on upper, lower, left, and right sides are used to adjust the height of the height adjusting device of a cover for an underground-buried inspection hole from the ground, the horizontality of the height adjusting device of a cover for an underground-buried inspection hole with respect to the ground can be adjusted. Since the height adjusting device of a cover for an underground-buried inspection hole has a rigid height adjusting structure, subsidence, separation, and the like can be prevented in advance even after the height adjusting device of a cover for an underground-buried inspection hole is constructed. 본 발명은 지하 매설 점검구 뚜껑의 높이조절장치에 관한 것으로, 보다 상세하게는 지하 매설 점검구 뚜껑의 높이조절장치의 내부에 회전에 의해 상하 이동되도록 한 높이 조절축을 형성함으로써, 지하 매설 점검구 뚜껑의 높이조절장치의 지면과의 높이 조절작업이 신속하고 용이하게 진행되어, 시공 설치기간 및 소요 인력을 절감할 수 있을 뿐만 아니라, 지하 매설 점검구 뚜껑의 높이조절장치 내의 높이 조절축을 이용하여 지하 매설 점검구 뚜껑의 높이조절장치와 지면과의 세밀한 높이 조절이 가능할 뿐만 아니라, 상하좌우 등에 구비된 높이조절축으로 지면과의 높이를 조정하기 때문에, 지하 매설 점검구 뚜껑의 높이조절장치와 지면과의 수평조절도 가능하며, 지하 매설 점검구 뚜껑의 높이조절장치의 높이조절 구조가 견고하여, 지하 매설 점검구 뚜껑의 높이조절장치의 시공 작업 후에도 침하 및 이격 현상 등을 미연에 방지하도록 한 것이다.
