Composite cylinder structures are widely used in various engineering fields. Monitoring the health state is an essential method for ensuring the safe operation of the structures. Embedded distributed fiber opti.
Optical fibers require special care during installation to ensure reliable operation. Installation guidelines regarding minimum bend radius, tensile loads, twisting, squeezing, or pinching of cable must be followed.
Due to harsh environments on site, robust sensing cables are required to ensure the integrity of the sensing fiber during the driving process. For that reason, IGMS normally uses prefabricated sensing cable.
For steel pipe piles, strain sensing FO cables with steel strands are generally installed on the steel pipe surface using welding and cementation. Then the pile is slowly driven into the soil layer. The installatio.
After fiber optic cables are installed, spliced and terminated, they must be tested. This testing will ensure that the data necessary to properly evaluate any future system malfunctions will be av nctioning. He's right – it is n t working.
