"Anchor rod element for linewise installation of BOTDA for monitoring ground surficial deformation"@en . . . . "Line-wise or areal deployment of optical cables for monitoring of distributed strain based on BOTDA (Brillouin Time Domain Analysis) method is a suitable tool for observation of slope movements at the ground level. The values of deformation are calculated from sequence of measurement episodes and compared within them. The scheme of measurement cable deployment can be chosen as line-wise or areal. The optical cable is fastened between anchoring rods. The change of distance between the anchoring rods is measured. The anchoring rod has thread on its top, which enables precise fitting of geodetic GPS (Global Positioning System) for determination of global position of the anchoring rod. The end points of installed line are located out of the active movements in the area. This assumption can be verified by GPS measurements as well. The optical cable is installed into a trench in the existing terrain or below the future embankment body. The anchoring rods are installed by dynamic penetration test equipment. After function check is the measurement optical cable in a protective sleeve poured with loose material and the trench is backfilled by the local soil, which was excavated previously. The basic part of the functional specimen is machined from steel rod. At one end, there is a cone for penetration and a standard inner thread at the opposite end. The anchoring rod can be re-used after lifting from the ground with extractor. The optical cables are fastened by couples of plates fitted by pair of M6 bolts directly into the anchoring rod or on an insert plate, which enables rotation of the couple of plates parallel with the slope inclination. Acknowledgement: The development of this functional specimen was carried out within the project MPO TIP FR-TI3/609 Research and development of detection and monitoring of critical areas of geotechnical constructions mainly in underground structures, mining industry and other engineering constructions."@en . .
