Construction method for main cable at auxiliary cable saddle in similar cable clamp form based on auxiliary tower later construction
The invention relates to the technical field of bridge construction, in particular to a construction method for a main cable at an auxiliary cable saddle in a cable-clip-like form based on auxiliary tower later construction. Comprising the following steps that S1, after a main tower is constructed, an auxiliary tower is constructed, and construction is stopped when the distance between the auxiliary tower and the tower top is set; s2, main cables are erected on the main tower and the anchorage, and the cable tightening process is completed; s3, the midspan part of the main cable between the two main towers is ballasted, and the side span part of the main cable between the main towers and the auxiliary towers is forced to be lifted upwards to the set height; and S4, auxiliary tower construction is completed, an auxiliary cable saddle is installed on the auxiliary tower, and main cable construction operation at the auxiliary cable saddle is conducted. The construction method is very simple, the construction difficulty of the complex suspension bridge is reduced, enough space can be provided for erection of the main cable side span part through step-by-step construction of the auxiliary tower, the main cable side span part is lifted by ballasting the main cable midspan part, installation of the main cable side span part and the auxiliary tower and subsequent construction of the auxiliary tower can be facilitated, and the construction efficiency is improved. And the construction efficiency is greatly improved.
本发明涉及桥梁施工技术领域，具体地指一种基于副塔后做的类索夹形式副索鞍处主缆施工方法。包括以下步骤：S1、主塔施工完成后，施工副塔，施工至距离塔顶设定距离停止；S2、在主塔和锚碇上架设主缆，并完成紧缆工序；S3、对两组主塔之间的主缆跨中部分进行压载，迫使主塔和副塔之间的主缆边跨部分向上抬升至设定高度；S4、完成副塔施工，在副塔上安装副索鞍，进行副索鞍处的主缆施工作业。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，通过分步施工副塔可以为主缆边跨部分的架设提供足够的空间，对主缆跨中部分进行压载使主缆边跨部分抬升，可以方便主缆边跨部分与副塔安装以及副塔后续施工，施工效率得到了极大的提升。
