Abstract Combined with the construction case of stay cable landscape lighting of Zhongba Bridge in Jinsha River,Cuiping District,Yibin,Sichuan,and by comparing and analyzing the traditional method of fixing luminaires with stainless steel hoop on stay cables by SpiderMan and the traction jackup method

it is concluded that the traction jackup method is safer and faster,with less labor time,controllable construction safety risks,convenient operation and maintenance,simple construction technology and high reliability. At the same time,it can greatly reduce the labor intensity of operators and avoid many uncontrollable risk factors.

Key wordslandscape lighting;traction jackup method;aluminum alloy welding;triangle traction wheel;guide wheel bracket;trapezoidal operating platform;DC switching power supply;fixed bearing pulley embedded parts

 

摘 要:结合四川省宜宾市翠屏区金沙江中坝大桥斜拉索景观照明施工案例,对比分析采用蜘蛛人在斜拉索上用不锈钢抱箍固定灯具的传统方法和牵引顶升法施工,得出结论:在大型高耸的斜拉索桥梁顶端勾勒天际线采用牵引顶升法施工,更安全快捷、用工时间少、施工安全风险可控、日后运营维修方便,且施工工艺简单、可靠性高;同时,可大大减轻作业人员劳动强度,规避诸多不可控风险因素。
