Beschreibung
Zusammenfassung:	The present invention relates to a sink hole full time and checking monitoring system to predict the sink hole by analyzing a shear strength of a ground measured by a vane tester, comprising: a vane blade inserted to an inner portion of the ground of a sink hole danger area at a predetermined depth; a torque generation portion applying torque to the vane blade; a vane tester including shear strength measuring portion to measure the shear strength of the corresponding ground through load of the vane blade; a monitoring apparatus to alert the sink hole when the shear strength is equal or less than a reference value after being inputted by the vane tester wherein the vane blade is located in the ground; and at least one bollard type signal apparatus protruded from the ground, and disposed to control pedestrians or vehicles. 본 발명은 베인시험장치로 측정한 지반의 전단강도를 분석하여 지반함몰을 예측하는 지반함몰 상시 및 확인감시시스템에 관한 것이다. 본 발명은 지반함몰 위험구역의 지반 내부에 소정의 깊이로 삽입되는 베인 블레이드, 베인 블레이드에 토크를 인가하는 토크생성부, 베인 블레이드의 부하를 통해 해당 지반의 전단강도를 계측하는 전단강도측정부를 포함하는 베인시험장치, 베인시험장치로부터 베인 블레이드가 위치한 지반의 전단강도를 입력받아 전단강도가 기준치 이하인 경우 지반함몰을 경고하는 모니터링장치, 및 지상으로 돌출되어 설치되며 보행자 또는 차량을 통제하기 위해 배치되는 적어도 하나 이상의 볼라드(bollard)형 신호장치를 포함한다.
