Construction method of carbon fiber inhaul cables
The invention relates to a construction method of carbon fiber inhaul cables. The construction method comprises the steps: (1) preparing the carbon fiber inhaul cables; (2) traction of the inhaul cables: (2.1) calculating the traction force of the inhaul cables: according to the length of the inhaul cables and the distance L0 between the upper end and the lower end of the inhaul cables, namely the center of an anchor bearing plate of the tower end and the center of an anchor bearing plate of the beam end, when the traction force is estimated to be T, enabling the distance [delta]L between the lower end of the inhaul cables and the anchor bearing plate of the beam end to be equal to L0-L+([omega]2LX2L0)/(24T2)-TL/AE, and before construction, according to cable force provided by bridge design and related technical parameters of the inhaul cables: L0, omega, L, LX, A and E, determining the number of soft traction carbon fiber bundles and the reserved length according to the relation between traction force T and [delta]L when anchor cup nuts are just rotated to be flat on the end faces of anchor cups when each pair of inhaul cables are tensioned; (2.2) releasing the inhaul cables; (2.3) hanging cables on a bridge tower; (2.4) hanging a cable at the beam end; and (2.5) carrying out temporary anchoring in the tower; (3) tensioning; and (4) adjusting the cable. The invention provides the construction method of the carbon fiber inhaul cables. Technical guidance is provided for application of a carbon fiber composite material in bridge engineering.
本发明涉及一种碳纤维拉索的施工方法，它包括：(1)碳纤维拉索的制备；(2)拉索的牵引：(2.1)拉索牵引力的计算：根据拉索的长度，上下两端即塔端和梁端锚垫板中心距离L0，估算出牵引力为T时，拉索下端离梁端锚垫板的距离ΔL：ΔL＝L0‑L+(ω2LX2L0)/(24T2)‑TL/AE，施工前根据桥梁设计所提供的索力及拉索的相关技术参数：L0、ω、L、LX、A、E，对每对拉索张拉时锚杯螺母刚旋平锚杯端面时的牵引力T和ΔL的关系确定软牵引碳纤维束根数和预留长度；(2.2)拉索放索；(2.3)桥塔挂索；(2.4)梁端挂索；(2.5)塔内临时锚固；(3)张拉；(4)调索。本发明提供了一种碳纤维拉索的施工方法，为碳纤维复合材料在桥梁工程的应用提供了技术指导。
