Suspension bridge main cable wire-wrapping-layer-free protection method
The invention relates to a suspension bridge main cable winding-layer-free protection method which comprises the following steps: after the procedures of cable tightening, cable clamp mounting and steel beam mounting of a suspension bridge main cable are completed, spraying protection is carried out on the main cable in a full-length range by adopting fireproof and anti-aging normal-temperature spraying high-elasticity liquid rubber; the spraying coverage range comprises a main cable non-cable-clamp area, a cable clamp, a tower top saddle cover area, a splay cable saddle and front anchor chamber splay cable area and a main cable strand anchoring area, the spraying thickness is 3-5 mm, and a full-length flexible protective sleeve is formed after the liquid rubber is solidified, so that main cables in the main cable non-cable-clamp area, the cable clamp, the cable saddle and the splay cable area are located in a complete closed protective sleeve. According to the cable clamp, no gap is formed at the cable clamp, the connector of the cable clamp is sealed, rainwater and water vapor can be effectively prevented from entering the main cable, the protection effect that the main cable is not rusted is achieved, and the wire winding cost and the dehumidification operation cost can be saved.
本发明涉及一种悬索桥主缆无缠丝层防护方法，悬索桥主缆完成紧缆、索夹安装、钢梁安装工序后，采用具有耐火、抗老化的常温喷涂高弹力液体橡胶对主缆全长度范围进行喷涂防护，喷涂覆盖范围包括主缆非索夹区、索夹、塔顶鞍罩区、散索鞍及前锚室散索区、主缆索股锚固区，喷涂厚度3～5mm,液体橡胶凝固后形成一个通长的柔性保护套，使主缆非索夹区、索夹处、索鞍处、散索区的主缆处于一个完整的密闭保护套内。本发明不会在索夹处形成缝隙，索夹本身的接口处也得以密封，能有效防止有雨水、水蒸气进入主缆，从而达到主缆不锈蚀的防护效果，并可节约缠丝费、抽湿运营费用。
