武汉鹦鹉洲长江大桥桥面板结合及湿接缝施工质量控制

A Study of Decks Connection & Wet Joint Construction Quality Control of Yingwuzhou Yangtze River Bridge in Wuhan

武汉鹦鹉洲长江大桥主桥为225 m+2×850 m+225 m三塔四跨钢板结合梁悬索桥。主桥桥面板安装采取在钢梁上焊接剪力钉,通过相邻板间绑扎连接钢筋网和二次浇筑湿接缝混凝土使之形成整体,对湿接缝进行精心养护与管理,保证钢板结合梁悬索桥改性沥青路面的施工质量,使用效果较好。

The main bridge of Wu han Yingwuzhou Yangtze River Bridge is three-tower & four-span steel composite beam suspension bridge with 225 m + 2 × 850 m + 225 m. The deck installation of main bridge is adopting welding shear studs on steel beams. Through the connection between adjacent decks lashing steel mesh and pouring wet joints second time, the concrete will be formed a whole. Make meticulous maintenance & management on the wet joints to ensure the construction quality of the modified asphalt pavement of steel decks composite beam suspension bridge, and the results show that it can arrive at great practical effects.
