(2) technical solution
In order to solve the above technical problem, the present invention provides a kind of parallel steel wire intelligence rope HiAm anchorage, comprising: more are parallel
Steel wire；Positioned at parallel steel wire side and inner couplings have the intelligent steel wire of fiber grating；Anchor cup, inside are equipped with several fixing sleeves
And tapered sleeve；Fixation hole is equipped in the fixing sleeve, the fixation hole and parallel steel wire one end are interference fitted；It is equipped in the tapered sleeve
Mounting hole, the mounting hole and intelligent steel wire are interference fitted.
In a first aspect, the intelligent steel wire of coupling fiber grating is handled after passing through wire sub-panel without pier nose, replace
Be to be slightly less than the tapered sleeve of intelligent steel wire diameter using internal diameter to be interference fitted, when making HiAm anchorage, tapered sleeve need to only be penetrated
Steel wire end will not damage fiber grating, improve laying survival rate and service life of the fiber grating in steel wire, expand
The big range of fiber grating.Wherein, tapered sleeve and intelligent steel wire are interference fit, assemble the circumference stress of generation as intelligent steel wire
Anchor force is provided, while tapered sleeve provides protection for the fiber grating of end.More preferably, magnitude of interference is less than on fiber grating
The spacing on surface and intelligent steel wire surface, to guarantee that fiber grating will not be contacted in tapered sleeve installation process, so as to cause optical fiber
The fracture of grating.
Currently, largely with parallel wire stay system as its main bearing member, Yi Taoping in Bridges in Our Country engineering
Row wire digging line system mainly bears the load of structure with cable body and both ends anchorage.Parallel wire stay system is as bridge
