The invention relates to the technical field of bridge engineering, in particular to a cable-stayed bridge steel tower top cable hanging structure and a stay cable construction method. A tower top longitudinal beam is fixedly arranged at the top of a steel tower, and a tower top guide pulley is arranged at the end of the tower top longitudinal beam. A hoisting steel wire rope connected with the winch bypasses the tower top guide pulley and is connected with the end part of the stay cable, so that the stay cable can be slowly hoisted near the height of the cable hole by utilizing the hoisting steel wire rope, then the stay cable is pulled into the cable hole through the guide steel wire rope, and the punching operation of the stay cable at the steel tower end is completed. The cable hanging structure and the stay cable construction method are safe, applicable, high in efficiency and low in construction cost in the hoisting high-altitude stay cable perforation operation, and can meet the operation requirements of stay cable high-altitude cable hanging.
本发明涉及桥梁工程技术领域，具体为一种斜拉桥钢塔顶挂索结构及斜拉索施工方法，通过在钢塔顶部固定设置一个塔顶纵梁，且于塔顶纵梁的端部设置有塔顶导向滑车，并将与卷扬机相连的吊装钢丝绳绕过塔顶导向滑车与斜拉索端部相连，从而可以利用吊装钢丝绳缓慢将斜拉索吊至索孔高度附近，之后通过导向钢丝绳将斜拉索拉入索孔内，完成斜拉索在钢塔端的穿孔作业；该挂索结构及斜拉索施工方法，在吊装高空斜拉索穿孔作业中安全适用，效率高，施工成本低，能够满足斜拉索高空挂索的作业需求。
