Transverse block main cable saddle suitable for space cable suspension bridge and construction method of transverse block main cable saddle
The invention discloses a transverse block main cable saddle suitable for a space cable suspension bridge and a construction method thereof, and the transverse block main cable saddle comprises a supporting platform which is fixedly installed on the top of a main tower; the upper bearing plate comprises two movable plates, the two movable plates are oppositely arranged on the two sides of the top of the supporting platform with the center line of the bridge as the axis and are in sliding connection with the supporting platform, and detachably-connected connecting plates are arranged on the adjacent sides of the two movable plates; any saddle head is fixed to the top of the corresponding movable plate and is provided with an independent saddle groove structure; the two transverse pushing devices are arranged to be used for pushing the corresponding movable plates in the transverse bridge direction; the longitudinal pushing device is used for pushing the upper bearing plate in the bridge direction. According to the method, the main cable saddle structure with the transverse blocks is matched with the transverse pushing device and the longitudinal pushing device, the shape of the main cable can be adjusted along with the erection progress of the main beam, the equipment investment cost is effectively reduced, the adjusting process is not limited by the conventional suspension bridge construction sequence, and the overall bridging construction flexibility and construction efficiency are greatly improved.
本发明公开了适用于空间缆悬索桥的横向分块主索鞍及其施工方法，包括：支撑平台，其固定安装在主塔塔顶上；上承板，其包括两个活动板，其以桥梁中心线为轴相对设置在支撑平台的顶部两侧并与其滑动连接，两个活动板相邻的一侧设有可拆卸连接的连接板；两个鞍头，任一鞍头固定在对应的活动板顶部且具有独立的鞍槽结构；两个横向顶推装置，其分别设置为用于沿横桥向顶推对应的活动板；纵向顶推装置，其设置为用于沿顺桥向顶推上承板。本发明通过横向分块的主索鞍结构与横、纵向顶推装置配合，能够随主梁架设进度对主缆线形进行调整，有效减少了设备投入成本，且调节过程不受常规的悬索桥施工顺序限制，大幅度提高了整体架桥施工灵活性和施工效率。
