SUBMERGED STRUCTURE LEAKAGE OPTICAL FIBER POSITIONING AND ORIENTING SYSTEM AND MONITORING METHOD WITHOUT HEAT SOURCE

摘要

The present invention discloses a heat source-free fiber positioning and orienting system for seepage of submerged or partially submerged structures and monitoring method thereof, which includes a plurality of seepage monitoring devices connected through rotary supports, wherein the seepage monitoring devices include first seepage monitoring units symmetrically distributed on the front and back and second seepage monitoring units symmetrically distributed on left and right, seepage monitoring fibers are distributed in the first seepage monitoring units and the second seepage monitoring units, and the seepage conditions of the submerged or partially submerged structures are monitored through the seepage monitoring fibers. The heat source-free fiber positioning and orienting system for the seepage of submerged or partially submerged structures according to the present invention has the characteristics of no heating, distribution manner, multiple orientations and synchronicity or the like, and has prominent advantages on such aspects like reducing the monitoring cost, improving the monitoring precision and engineering practicability or the like; and through flexibly disposing the seepage monitoring device in the submerged or partially-submerged structures, the seepage position and direction are obtained through comparison of calibrated fibers and the seepage monitoring fibers; therefore, the monitoring method of the present invention is simple to operate and has accurate results.
