Installation method of inclined suspender of basket arch bridge
The invention relates to the technical field of bridge engineering, in particular to an installation method of an inclined suspender of a basket arch bridge, which comprises the following steps that S1, a protection device is arranged on a lifting path of a suspender; S2, a suspender is bound through a first working cable, and the suspender is lifted till the top end of the suspender reaches the lower chord of the arch rib; S3, the suspender is bound through the second working cable, the first working cable is removed, and the suspender is lifted to penetrate through the protection space till the top end of the suspender reaches the anchor head position of the upper chord of the arch rib; and S4, an anchor head nut is installed on the suspender, and the suspender is fixed. According to the installation method for the inclined suspender of the basket arch bridge, scraping and collision between the suspender and the arch rib component are converted into roller rotation, direct scraping and collision between the suspender and the arch rib component are avoided, the time needed by later repair is shortened, meanwhile, a lifting point conversion mode in the lifting process of the suspender is adopted, the lifting rod can always move along the lifting path, a protection device can be better arranged in a matched mode, and optimal lifting with protection is achieved for the lifting rod.
本发明涉及桥梁工程技术领域，特别涉及一种提篮拱桥倾斜式吊杆安装方法，包括如下步骤：S1：在吊杆的起吊路径上设置防护装置；S2：通过第一工作索绑扎吊杆，起吊吊杆，至吊杆顶端部达到拱肋下弦；S3：通过第二工作索绑扎吊杆，解除第一工作索，起吊吊杆穿过所述防护空间，至吊杆顶端部达到拱肋上弦锚头位置；S4：在吊杆上安装锚头螺母，固定吊杆。本发明的一种提篮拱桥倾斜式吊杆安装方法，将吊杆与拱肋构件之间的刮碰转变为滚筒转动，避免吊杆直接与拱肋构件发生刮碰，减少后期修补所需的时间，同时，采用在吊杆起吊过程中的吊点转换方式，使吊杆能够始终保持沿起吊路径移动，能够更好的进行防护装置的配套设置，对吊杆实现最优的带防护起吊。
