Provided is an intelligent extruding stay
rope based on a filled type
epoxy coating steel strand. One of side wires of the
epoxy steel strand is a side wire with a groove, and
optical fiber and an
optical fiber grating sensor are implanted in the groove; the Bragg
grating wavelength change of the intelligent side wire of the implanted
epoxy steel strand is demodulated and analyzed by using an
optical fiber grating demodulation device, and thus the stay
rope force is measured; due to the fact that transmission of optical signals is not influenced by the environment, the optical
fiber and the optical
fiber grating sensor can stably and correctly monitor the stay
rope force for a long time. An anchoring sleeve is of a single-inner-hole multi-inner-cone structure, the anchoring force is strengthened, on one hand, the epoxy layer of the filled type epoxy
coating steel strand is not needed to be peeled, and on the other hand, the outer
diameter of a whole anchor head is reduced. Inclinationis formed on the outer side surface of a sealing ring in a sealing cylinder, and the inclination is 10 degrees larger than the inner inclination of the sealing cylinder. The defects of multiple innerholes (the number of the holes is identical to that of the anchoring steel strands) and large
machining difficulty of the anchoring sleeve of an existing extruding type stay rope are overcome, and thesingle-hole multi-inner-cone anchoring sleeve for the extruding stay rope based on the filled type epoxy
coating steel strand is provided and is convenient to
machine.
