Asymmetric construction method for large-span suspension bridge catwalk
The invention relates to the technical field of bridge construction, and discloses a large-span suspension bridge catwalk asymmetric construction method which comprises the following steps of slide-resistant pile construction, anchoring steel frame embedding and tower top anchoring beam installation. Catwalk pilot cables pass through the river, and catwalk main bearing cables are installed; catwalk bearing cables are used as rail cables to install steel strands, the two ends of each steel strand are anchored, and the tensioning ends are arranged on the tops of the slide-resistant piles; a tower top catwalk main bearing cable anchoring device is installed, and the sag of catwalk bearing cables is adjusted in a span-by-span mode from the shore A to the shore B; b, anchoring a bearing cable at the top of a shore tower, and adjusting tension according to the tower deviation condition in the process to ensure that a main tower is vertical; a catwalk surface layer is laid, B-bank anchorage and splay cable saddle construction is completed, and B-bank side catwalk bearing cables are changed from anti-slide piles to saddles one by one; and B, cable adjustment and surface layer pavement are conducted on the shoreside cross catwalk, the prestressed steel strands are dismantled, and catwalk construction is completed. The asymmetric construction method for the large-span suspension bridge catwalk is high in safety, good in economical efficiency, high in applicability, good in universality and suitable for suspension bridge construction.
本发明涉及桥梁施工技术领域，公开了一种大跨度悬索桥猫道不对称施工方法，方法步骤包括如下：抗滑桩施工、锚固钢架预埋，塔顶锚固梁安装；猫道先导索过江，猫道主承重索安装；利用猫道承重索作为轨索安装钢绞线，钢绞线两端锚固、张拉端设在抗滑桩顶；安装塔顶猫道主承重索锚固装置，由A岸向B岸逐跨调节猫道承重索垂度；B岸塔顶锚固承重索，过程中根据塔偏情况调节拉力确保主塔竖直；猫道面层铺设，B岸锚碇及散索鞍施工完成，B岸边跨猫道承重索逐根由抗滑桩改换至鞍部；B岸边跨猫道调索及面层铺装，预应力钢绞线拆除，完成猫道施工。该大跨度悬索桥猫道不对称施工方法，安全性高，经济性好，适用性强，通用性好，适用于悬索桥施工。
