摘要:
针对国内外悬索桥主缆防腐蚀传统技术的缺点,提出一种悬索桥主缆除湿系统设计方法,该方法通过送气管和送气罩将干空气送入主缆空隙,干空气吸收主缆内的水分后从排气罩排出,降低主缆内空气相对湿度,从而有效避免主缆钢丝腐蚀.通过实例验证所提出的方法,并为某悬索桥设计了主缆除湿系统,确定了合理的送气长度、除湿时间、送气流量及送气压力;分析了送气长度和泄漏率对送气流量和除湿时间的影响,主缆内气流量和除湿时间与送气流量成正比,与送气长度和泄漏率成反比;评述了主缆除湿系统设备选型和能耗分析.
Abstract:
In consideration of the shortcomings of traditional technology of corrosion prevention of suspension bridge cables at home and abroad, a new dehumidification method for suspension bridge cables is put forward. Dry air is put into main cables by air duct and cover of air supply, the dry air which absorbs moisture content is discharged from cover of air exhaust, the relative air humidity of main cables is reduced, thus the steel wires of main cables can avoid corrosion. The range of related design parameters and calculation equation is discussed, and a design method of dehumidification system for suspension bridge cables is put forth. A Dehumidification system for suspension bridge cables is designed for a certain suspension bridge, and the reasonable length of air supply, drying time, volume of air supply and the pressure of air supply are determined. The effect of air supply length and leakage ratio on air supply flow and dehumidification time is analyzed. Air flow in main cables and dehumidification time are proportional to air supply flow and inversely proportional to air supply length and leakage ratio. Equipment selection of dehumidification system for main cables and energy consumption analysis are discussed.
