Cable-clip-like auxiliary cable saddle mounting method based on fabricated temporary cable saddle
The invention belongs to the technical field of suspension bridge upper structure construction, and particularly relates to a cable clamp type auxiliary cable saddle installation method based on an assembly type temporary cable saddle. The invention discloses a cable-clip-like auxiliary cable saddle mounting method based on an assembled temporary cable saddle. The cable-clip-like auxiliary cable saddle mounting method comprises the following steps that mounting construction of a main tower and an auxiliary tower is completed; a main cable saddle and an assembly type temporary cable saddle are installed, then cable strand erection is conducted on the basis of the assembly type temporary cable saddle, and cable strand sag alignment, cable tightening and cable clamp installation are completed; hoisting a stiffening beam in the midspan, pushing the main cable saddle towards the midspan to lift the main cable to a set height, dismounting the fabricated temporary cable saddle, mounting the lower half saddle body of the cable-clip-like auxiliary cable saddle, and then mounting the upper half saddle body to complete the mounting of the cable-clip-like auxiliary cable saddle. By means of the structural characteristics of the suspension bridge, additional internal force generated on the main tower and the auxiliary tower and bidirectional pushing of the main cable saddle are avoided, sag adjustment of the cable strands is facilitated, safety and reliability are achieved, and the safety risk in the whole construction process is reduced.
本发明属于悬索桥上部结构施工技术领域，特别涉及一种基于装配式临时索鞍的类索夹式副索鞍安装方法。一种基于装配式临时索鞍的类索夹式副索鞍安装方法，包括以下步骤：完成主塔及副塔的安装施工；安装主索鞍及装配式临时索鞍，然后基于装配式临时索鞍进行索股架设并完成索股垂度调正、紧缆及索夹安装；再在中跨进行加劲梁的吊装，配合主索鞍向跨中方向顶推使主缆抬升至设定高度，拆除装配式临时索鞍并安装类索夹式副索鞍下半鞍体，然后安装上半鞍体，完成类索夹式副索鞍安装。本发明利用了悬索桥自身的结构特性，避免了对主塔、副塔产生附加内力及主索鞍的双向顶推，且方便索股垂度调整，更加安全可靠，降低了整个施工过程中的安全风险。
