Abstract
1. Устройство для измерения деформаций грунта, содержащее чувствительный к деформации сенсорный оптический кабель, измерительный блок, связанный с кабелем, якоря, связанные с кабелем и с грунтом, отличающееся тем, что снабжено системой защиты кабеля от разрушения, включающей встроенный в каждый якорь предохранитель. ! 2. Устройство для измерения деформаций грунта по п.1, отличающееся тем, что каждый якорь связан с кабелем посредством разъемного зажима, а с грунтом - упорной пластиной. ! 3. Устройство по п.2, отличающееся тем, что предохранитель включает крепеж, выполненный с возможностью крепления упорной пластины к разъемному зажиму, причем при приложении к крепежу заданной нагрузки последний разрушается, обеспечивая тем самым свободу перемещения кабеля относительно упорной пластины. ! 4. Устройство по п.3, отличающееся тем, что крепеж выполнен в виде защелок, расположенных на упорной пластине якоря и находящихся в зацеплении с разъемным зажимом. ! 5. Устройство по п.2, отличающееся тем, что предохранитель включает крепеж, выполненный с возможностью крепления кабеля к разъемному зажиму, причем при приложении к крепежу заданной нагрузки последний деформируется, обеспечивая тем самым свободу перемещения кабеля относительно упорной пластины. ! 6. Устройство по п.5, отличающееся тем, что крепеж выполнен в виде размещенного в пазу эластичного вкладыша с внутренним продольным каналом для размещения кабеля и жесткой калибровочной пластины, установленной в разъеме зажима, причем эластичный вкладыш имеет наружную поверхность, ответную поверхности паза, и поверхность продольного канала, ответную поверхности сенсорног� 1. A device for measuring soil deformations, containing a strain-sensitive sensor optical cable, a measuring unit connected to the cable, anchors connected to the cable and soil, characterized in that it is equipped with a cable protection system from destruction, including a fuse integrated in each armature. ! 2. A device for measuring soil deformations according to claim 1, characterized in that each anchor is connected to the cable by means of a detachable clamp, and to the soil by a thrust plate. ! 3. The device according to claim 2, characterized in that the fuse includes fasteners configured to fasten the thrust plate to the detachable clip, and when a predetermined load is applied to the fastener, the latter is destroyed, thereby ensuring freedom of movement of the cable relative to the thrust plate. ! 4. The device according to claim 3, characterized in that the fasteners are made in the form of latches located on the thrust plate of the armature and meshed with a detachable clip. ! 5. The device according to claim 2, characterized in that the fuse includes fasteners configured to fasten the cable to the detachable clip, and when a specified load is applied to the fastener, the latter is deformed, thereby ensuring freedom of movement of the cable relative to the thrust plate. ! 6. The device according to claim 5, characterized in that the fastener is made in the form of an elastic insert placed in a groove with an internal longitudinal channel for accommodating a cable and a rigid calibration plate installed in the clamp connector, the elastic insert having an outer surface corresponding to the groove surface, and surface of the longitudinal channel corresponding to the surface of the sensor
