摘要
文章针对郑徐铁路客运专线萧县特大桥桥上CRTS Ⅲ型先张预应力无砟轨道板铺设施工中,轨道板粗铺精度不易控制、"门"型连接钢筋无法精确定位等一系列难题,通过对CRTS Ⅲ型先张预应力无砟轨道板粗铺施工技术研究,自主设计应用了轨道板粗铺精确定位标尺及配套的施工方法。该方法优化了"门"型钢筋连接筋的绑扎方式,有效控制了轨道板粗铺作业的精确,提高了施工效率。
CRTS Ⅲ slab ballastless track is adopted for the Xiaoxian super major bridge of Zhengzhou-Xuzhou railway passenger dedicated line. In the construction of CRTS Ⅲ slab ballastless track, the accuracy of track slab is not easy to be controlled and the door-type reinforcing bars connection can not be accurately located. Through the study of construction technology for CRTS Ⅲ ballastless track plate, accurate positioning ruler and the supporting method of track plate is designed and applied. The binding way of door-type connecting reinforcement is optimized by this method, which effectively controls the accuracy of track plate laying and enhances the construction efficiency.
