Inhaul cable circulating traction installation construction method for single-tower single-cable-plane cable-stayed bridge
The invention relates to an inhaul cable circulating traction installation construction method for a single-tower single-cable-plane cable-stayed bridge. The spatial position of a lower cable guide pipe is controlled through combination of an internal positioning bolt and a lower correcting body. A beam top hanging plate is arranged on the supporting anchor beam, and the position of the platform supporting beam is controlled through the combination of a connecting shoe groove and an inclined supporting bolt; a transverse positioning bolt and a vertical positioning bolt are combined to control the position of the lower portion of the upper cable guide pipe, and an upper correcting body is adopted to control the position of the upper portion of the upper cable guide pipe; an alignment label is arranged at the top end of the lower cable guide pipe, and a built-in positioning pipe, an annular positioning bolt and a centering tester are arranged in the upper cable guide pipe; the anchor beam back plate is adopted to control the positions of the inhaul cable position control ring and the annular inhaul cable, and compensation tensioning is conducted on the first anchor plate and the annular inhaul cable through the second anchor plate and the post-tensioning screw rod; the pipeline position control hoop and the locking bag are adopted to control the spatial position of the inhaul cable protection pipe. According to the method, the mounting and positioning precision of the cable guide pipe is improved, and the tension stress of the circumferential inhaul cable is accurately controlled.
本发明涉及独塔单索面斜拉桥拉索循环牵引安装施工方法，采用内部定位栓和下部校位体组合控制下部索导管的空间位置；在支撑锚梁上设置了梁顶挂板，通过连接靴槽和斜向撑栓组合控制平台撑梁的位置；采用横向调位栓和竖向调位栓组合控制上部索导管下部的位置，采用上部校位体控制上部索导管上部的位置；在下部索导管的顶端设置对准贴标，在上部索导管内设置内置定位管、环向定位栓和对中测试仪；采用锚梁背板控制拉索控位环及环向拉索的位置，通过第二锚板及后张拉螺杆对第一锚板及环向拉索进行补偿张拉；采用管道控位箍及锁固囊袋控制拉索防护管的空间位置。本发明提高了索导管安装定位的精度，实现了环向拉索张拉应力准确控制。
