Temporary inhaul cable construction method suitable for cable-first and beam-second construction of suspension bridge
The invention discloses a temporary inhaul cable installing, tensioning and releasingconstruction method suitable for cable-first and beam-second construction of a self-anchored suspension bridge. The temporary inhaul cable is made of a steel strand, a steel wire rope or a parallel steel wire, one end of the temporary inhaul cable is made into a fork lug structure to form a fixed connecting end, and the other end of the temporary inhaul cable is made into a tensioning structure with an adjustable nut. A traction system is formed by a winch, a traction cable, a tackle and a hanging ring, erection of the temporary inhaul cable is achieved through a load-bearing rope arranged between the anchorage and the anchoring beam, the problems of a limited beam bottom space and overwater high-altitude installation are solved, the cost is saved, and the construction efficiency is improved. A tensioning and releasing system is composed of a tensioning strut angle, a center hole jack, the tensioning nut, the tensioning screw rod and the extension rod, multiple times of graded tensioning and releasing of the temporary inhaul cable are achieved, construction is safe and convenient, and the construction precision is guaranteed.
本发明公开了一种适用于自锚式悬索桥先缆后梁施工的临时拉索安装、张拉及释放的施工方法，该临时拉索采用钢绞线，钢丝绳或平行钢丝进行制作，一端制作成叉耳结构，形成固定连接端，另一端制作成螺母可调节的张拉结构，通过卷扬机、牵引索、滑车及吊环组成牵引系统，利用锚碇及锚固梁间布置的承重绳实现了临时拉锁的架设，解决了梁底空间受限及水上高空安装难题，节省了成本，提高了施工工效。通过张拉撑角、穿心千斤顶、张拉螺母、张拉螺杆及接长杆组成张拉与释放系统，实现了临时拉锁的多次分级张拉与释放，施工安全便捷且保证了施工精度。
