BANK BODY DISTORTION MEASURING SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a bank body distortion measuring sensor easy to follow the movement of earth of the inside of a bank body, capable of grasping the initial phenomenon of bank body collapse which is thought to be produced due to leakage water by large distortion as a preecho, and easily constructing a long bank. SOLUTION: In a bank body measuring sensor comprising an optical cable for a sensor 10 laid along the longitudinal direction on the bank body 30 and a plurality of sensor weight 20 fixed at proper intervals in the longitudinal direction of the optical cable for the sensor 10, the sensor weight 20 is fixed on the optical cable for the sensor 10 away from a vertical straight line passing the centroid of each sensor weight 20.
