Inhaul cable anchoring device for cable-stayed bridge and tensioning construction method
The invention discloses an inhaul cable anchoring device for a cable-stayed bridge and a tensioning construction method. The anchoring device comprises a first anchoring seat and a second anchoring seat which are formed in a split structure, and inhaul cable penetrating holes are formed in the first anchoring seat and the second anchoring seat respectively. The first anchoring base and the second anchoring base are fixedly connected to the opposite tower walls in the hollow cable bent tower. At least one pull rod assembly is connected between the first anchoring base and the second anchoring base, and the pull rod assembly exerts horizontal pull force on the first anchoring base and the second anchoring base which are fixed to the opposite tower walls of the hollow cable bent tower. The size of the forming structure is greatly reduced, the weight is greatly reduced, and due to the fact that the problem of steel corbel bearing does not exist, the technical requirement for assembly precision is low, the technical difficulty of installation is small, and the technical requirement for the internal size of the cable bent tower is small.
本发明公开了一种斜拉桥用拉索锚固装置及张拉施工方法。所述锚固装置包括以分体结构成型的锚固座一和锚固座二，所述锚固座一和所述锚固座二上分别成型有拉索穿孔；所述锚固座一和所述锚固座二固定连接在空心索塔内的相对塔壁上；所述锚固座一和所述锚固座二之间连接有至少一根拉杆组件，所述拉杆组件对空心索塔相对塔壁上固定好的所述锚固座一和所述锚固座二施加水平拉力。本发明的成型结构尺寸大幅缩小，重量大幅减轻，亦由于不存在钢牛腿承坐的问题而使得组装精度技术要求低、安装技术难度小，对索塔内部尺寸的技术要求小。
