Construction method for main cable at auxiliary cable saddle in similar cable clamp form based on main cable saddle pre-bias
The invention relates to the technical field of bridge construction, in particular to a construction method for a main cable at a cable-clip-like auxiliary cable saddle based on main cable saddle pre-bias. Comprising the following steps that S1, a main tower, an auxiliary tower and an anchorage are constructed, a main cable is erected based on the main tower, and the main cable is installed on a main cable saddle on the main tower; s2, the main cable saddle is driven to move towards the midspan, the midspan part of the main cable is made to face downwards, and the side span part of the main cable is made to move upwards to the set height; and S3, an auxiliary cable saddle is installed on the top of the auxiliary tower, the main cable saddle is driven to reset towards the side span until the side span part of the main cable falls into the auxiliary cable saddle, and the side span part of the main cable is connected with the auxiliary cable saddle. The construction method is very simple, the construction difficulty of the complex suspension bridge is reduced, the main cable side span part is lifted by pushing the main cable saddle in the bridge direction, rapid installation of the lower saddle body of the auxiliary cable saddle is facilitated, the main cable saddle is pushed reversely in the bridge direction subsequently to enable the main cable side span part to be adjusted back, connection of the auxiliary cable saddle and the main cable side span part is facilitated, and the construction efficiency of the suspension bridge is improved. And the whole construction is very convenient.
本发明涉及桥梁施工技术领域，具体地指一种基于主索鞍预偏的类索夹形式副索鞍处主缆施工方法。包括以下步骤：S1、施工主塔、副塔和锚碇，基于主塔架设主缆，将主缆安装于主塔上的主索鞍；S2、驱动主索鞍向中跨移动，使主缆跨中部分向下，主缆边跨部分向上移动至设定高度；S3、在副塔塔顶安装副索鞍，驱动主索鞍向边跨复位，直至主缆边跨部分落入副索鞍，将主缆边跨部分与副索鞍进行连接。本申请的施工方法非常的简单，降低了复杂悬索桥的施工难度，通过顺桥向顶推主索鞍完成主缆边跨部分的抬升，方便副索鞍下鞍体的快速安装，后续顺桥向反向顶推主索鞍使主缆边跨部分回调，方便副索鞍和主缆边跨部分的连接，整体施工极为方便。
