小半径曲线地段喂梁作业的难点及解决方法
THE DIFFICULTY AND SOLUTION OF BRIDGE ERECTION IN SMALL RADIUS CURVE ZONE
【摘要】 从分析最小喂梁长度与曲线半径及双梁式架桥机后机臂长度等参数之间的关系出发 ,通过采取拨道和预偏装等措施局部扩大曲线半径 ,满足喂梁作业的要求。
【Abstract】 On the basis of relationship among the minimal extending length、small radius and the length of back beam, the difficulty of bridge erection is solved by turning track and offset in advance.
