Space special-shaped steel arch bridge inhaul cable positioning method and positioning device thereof
The invention relates to the technical field of bridge inhaul cable construction, in particular to a spatial special-shaped steel arch bridge inhaul cable positioning method and a positioning device.The positioning method comprises the following steps that S1, a traction rope is fixed to the circle center of a sling mounting hole in a steel anchor box; s2, a pulling rope extends into the arch rib guide rope pipe along the upper end of the arch rib guide rope pipe and extends into the anchor pulling plate guide rope pipe to be connected with a hanging ring on an anchor pulling plate, and the pulling rope is adjusted to be in a straightened state; s3, the distance between the traction rope and the inner wall of the anchor pulling plate guide rope pipe is measured at the position of an opening of the anchor pulling plate guide rope pipe, the position of the anchor pulling plate is correspondingly adjusted, and the traction rope is made to be located on the center line of the anchor pulling plate guide rope pipe; and S4, the anchor pulling plate and the beam surface are welded and fixed, and the traction rope is removed. Before the sling is installed, the anchor pulling plate located on the beam face is accurately positioned through the traction rope, so that the axis of the anchor pulling plate guide rope pipe is aligned with the axis of the arch rib guide rope pipe, and the installation precision of the sling in the arch rib guide rope pipe and the anchor pulling plate guide rope pipe is improved.
本发明涉及桥梁拉索施工技术领域，具体涉及一种空间异形钢拱桥拉索定位方法及其定位装置，其中发放包括如下步骤：S1、在钢锚箱上吊索安装孔的圆心处固定牵引绳；S2、将牵引绳沿拱肋导索管上端伸入，并伸入到锚拉板导索管内与锚拉板上的挂环连接，调整牵引绳使牵引绳处于绷直状态；S3、在锚拉板导索管管口位置测量牵引绳到锚拉板导索管内壁之间的间距，相应调整锚拉板的位置，使牵引绳位于锚拉板导索管的中心线上；S4、将锚拉板与梁面焊接固定，并拆除牵引绳。在吊索安装前首先通过牵引绳对位于梁面上的锚拉板进行精确定位，使锚拉板导索管与拱肋导索管的轴线对齐，提升吊索在拱肋导索管和锚拉板导索管中的安装精度。
