Title:
METHOD FOR MANUFACTURING HIGH-PRECISION AND ULTRA-LONG STANDARD WIRE OF MAIN CABLE STRAND OF SUSPENSION BRIDGE
Document Type and Number:
WIPO Patent Application WO/2023/029216
Kind Code:
A1
Abstract:
A method for manufacturing a high-precision and ultra-long standard wire (8) of a main cable strand of a suspension bridge, the method comprising the manufacturing of a reference wire (7): converting mark requirements of a main cable strand into length marks on multiple reference wires (7); numbering a mark point corresponding to each segment mark length; and marking, in a projection manner, one reference wire (7) with all the mark points on the multiple reference wires (7). The method further comprises the manufacturing of a standard wire (8): on a pedestal, making the reference wire (7) and the standard wire (8) achieve the same stress state by means of weight loading; during marking, the position of the reference wire (7) remaining unchanged, the standard wire (8) and a main cable strand having an equal length, dividing the standard wire (8) into several segments, each of which have a length equal to that of the reference wire (7), sequentially marking the several segments of the standard wire (8) with reference to the serial numbers of the mark points on the reference wire (7), and moving to the next segment after a segment has been marked; and sequentially completing the manufacturing of the whole standard wire (8). The method eliminates a length error caused by the elastic modulus and diameter deviations of a reference wire (7) and a standard wire (8), thereby improving the length precision of the standard wire (8).
