GROUND SUBSIDENCE SENSOR AND SYSTEM AND METHOD FOR MONITERING HYBRID TYPE GROUND SUBSIDENCE USING THEREOF

摘要

The present invention provides: a ground subsidence sensor capable of efficiently monitoring ground subsidence by properly corresponding to deformation of ground and improving stability and durability of a measuring unit by having composition in which the measuring unit using light is installed in a case unit with an elastic coefficient same as the elastic coefficient of soil; a hybrid type ground subsidence monitoring system using the same, and a method for the same. To achieve the purpose of the present invention, the ground subsidence sensor detecting deformation due to subsidence of the ground includes: the at least one or more measuring units measuring displacement due to the ground subsidence by an interaction of receiving and transmitting an optical signal; and the case unit covering the outer surface of the measuring unit and supporting the measuring unit in order for the measuring unit to be fixed. The case unit is formed of a plastic material with the elastic coefficient same as that of the soil in the ground in which the ground subsidence sensor is installed. Therefore, the ground subsidence sensor can improve stability and durability of the measuring unit by having the composition in which the measuring unit is installed in the case unit. Also, the ground subsidence sensor can properly correspond to the deformation due to the subsidence of the ground using the case unit with the elastic coefficient same as that of the soil.
