FIELD: measurement equipment.
SUBSTANCE: device for soil deformation measurement comprises a deformation-sensitive sensor optical cable, a measurement block connected with a cable, anchors connected to a cable and soil and is equipped with a system of cable protection against damage, including a safety fuse within each anchor, which actuates in case, when the force acting at the side of the anchor at the sensor cable exceeds the specified value.
EFFECT: provision of the possibility to limit a force transferred with an anchor to a sensor cable, in process of anchors displacement relative to each other, caused by soil movements, regardless of soil properties, which may be known unaccurately or change with time.
