重庆永川长江公路大桥钢箱梁锚箱作为主要的受力构件,保证制作精度致关重要。而钢箱梁锚箱结构复杂、焊接量大、焊接要求高且焊接操作空间狭小的特点,使得锚箱制作精度控制又成为困难。通过对钢箱梁锚箱结构的认真分析,结合制作工艺,在制作过程中采取分步骤组焊、严格控制组焊顺序及预留配切量等措施,使钢箱梁锚箱结构的制作精度满足设计及相关标准规范的要求。
Chongqing Yongchuan Yangtze River Bridge Steel Box girder anchor box as the main force components, to ensure the accuracy of production is crucial. The steel box girder anchorage box structure is complex, large amount of welding, high welding requirements and welding operation of small space characteristics, making the manufacture of anchor box accuracy control has become difficult. Through the careful analysis of steel box girder anchor box structure, combined with the production process, in the production process to take step by step group welding, rigorous control of the welding sequence and the amount of reserve with the amount of such measures to make steel box girder anchor box production accuracy Meet the design and related standards and requirements.
