Strand pulling construction method for ultra-long steel strand of continuous beam
The invention discloses a strand pulling construction method for an ultra-long steel strand of a continuous beam. The strand pulling construction method comprises the following steps: pulling glass fibers in the continuous beam through a glass fiber strand pulling machine; after the glass fibers pass through, connecting the glass fibers with a first steel wire rope, manually pulling after connection, and taking the first steel wire rope as a lead; connecting the first steel wire rope and the second steel wire rope through a buckle, checking a connector, a winch is arranged on the small mileageside, and dragging the second steel wire rope through the first steel wire rope through winch construction; and the second steel wire rope is connected with the multiple steel strands in a buckled mode, the multiple steel strands are dragged from the corrugated pipe through the winch, and the multiple steel strands are fixed through the anchorage device. The problem that in the prior art, in thelarge-span bridge construction process, the steel strand bundle penetrating construction difficulty is large is solved. The method has the advantages that construction equipment is simple, and materials are conventional and easy to obtain; the construction method is simple and easy to implement, and tasks which cannot be completed by the maximum strand pulling machine are completed; and the construction speed is high, and steel strand overall strand pulling can be completed at a time.
本发明公开了一种连续梁超长束钢绞线穿束施工方法，包括步骤：将玻璃纤维通过玻璃纤维穿束机在连续梁中穿束；在玻璃纤维通过之后，将玻璃纤维与第一钢丝绳连接，连接后人工拽拉，将第一钢丝绳作为引线；将第一钢丝绳与第二钢丝绳采用卡扣连接，检查接口，在小里程侧布置卷扬机，采用卷扬机施工，将第二钢丝绳通过第一钢丝绳拽过来；将第二钢丝绳与多根钢绞线卡扣连接，通过卷扬机将多根钢绞线从波纹管内拖拽，将多根钢绞线用锚具固定。目的为解决现有技术大跨度桥梁施工过程中钢绞线穿束施工难度大的问题。效果为：施工设备简单且材料常规，易获取；施工方法简单易实现，完成最大穿束机无法完成的任务；施工速度快，可一次完成钢绞线整体穿束。
