Construction method of spatial main cable suspension bridge handrail rope
The invention provides a construction method of a spatial main cable suspension bridge handrail rope, and relates to the technical field of bridge engineering. The method aims at installation and construction of the corresponding handrail rope in the arrangement mode that the larger the distance between the two main cables close to the center position of the suspension bridge is, the smaller the distance between the two main cables close to the bridge tower positions at the two ends of the suspension bridge is, and the multiple branch points are arranged on the handrail rope; the handrail rope and the inhaul cable are installed in three batches, and corresponding points are selected for construction operation in the installation process of each batch, so that the conditions that construction procedures interfere with one another, the construction steps are complicated, the operation process is tedious and the like under the condition that only one-time installation is adopted are avoided; according to the invention, equipment and constructors required by construction are simplified, gradual stretching installation can be realized by a multi-batch installation mode, the stress is more uniform, and the damage of the handrail rope and a corresponding stretching device caused by overlarge tensile force due to one-time stretching is avoided.
本发明提供一种空间主缆悬索桥扶手绳的施工方法，涉及桥梁工程技术领域。本发明所针对的是两根主缆间距为靠近悬索桥的中心位置相隔的距离越大，越靠近悬索桥两端的桥塔位置相隔的距离越小的排布方式的对应扶手绳的安装施工，其中扶手绳上设置了多个分点，并且扶手绳和拉索之间分成三个批次的安装，每批安装的过程中选择相应的分点进行施工操作，避免了仅通过一次安装方式的条件下造成施工工序相互干扰、施工步骤繁杂，操作过程繁琐等情况，本发明不仅精简了施工所需的设备及施工人员，并且多批次的安装方式能够实现循序渐进地逐次拉伸安装，受力更加均匀，不会因为一次拉伸造成拉力过大造成扶手绳及相应的拉伸装置的损坏。
