Replaceable suspension bridge anchorage carbon fiber anchoring inhaul cable structure and replacement method
The invention relates to a replaceable suspension bridge anchorage carbon fiber anchoring inhaul cable structure and a replacement method. A replaceable suspension bridge anchorage carbon fiber anchoring inhaul cable structure comprises an anchoring inhaul cable, a main cable strand anchor head and an anchorage embedded pipe. The anchoring inhaul cable is the carbon fiber composite material inhaul cable, and the carbon fiber composite material is extremely high in corrosion resistance, so that the problem of corrosion prevention of the suspension bridge anchoring system can be effectively solved, the service life is longer, the material strength is high, the material utilization rate is high, and the anchoring inhaul cable can be used as the anchoring inhaul cable of the suspension bridge. According to the scheme, the anchoring inhaul cable is in pin joint with the main cable strand anchor head, the knuckle bearing is arranged, and the spherical washer is arranged between the locking nut at the rear end and the anchor bearing plate, so that relative rotation can be formed between the locking nut and the anchor bearing plate, and the bending degree of the carbon fiber composite inhaul cable can be reduced through the two modes; the service life of the carbon fiber composite inhaul cable is prolonged; and an anchoring pull rod connected with the main cable at the front end in the prior art is omitted, so that the stress path is simpler and clearer.
本发明涉及一种可更换悬索桥锚碇碳纤维锚固拉索构造及更换方法。一种可更换悬索桥锚碇碳纤维锚固拉索构造，包括锚固拉索、主缆索股锚头和锚碇预埋管；锚固拉索为碳纤维复合材料拉索，碳纤维复合材料耐腐蚀性极强，因此可以有效解决悬索桥锚固系统防腐问题，使用寿命更长，而且材料强度高，材料利用率高，能够用于作为悬索桥的锚固拉索。本方案锚固拉索与主缆索股锚头间采用销接，并且设置关节轴承，在后端锁紧螺母和锚垫板之间设置球面垫圈，使锁紧螺母与锚垫板之间能够形成相对转动，两种方式均能够减小碳纤维复合材料拉索的自身弯折程度，提高碳纤维复合材料拉索使用寿命；且取消了现有技术前端与主缆连接的锚固拉杆，受力路径更加简单和清晰。
