Stay cable construction method of extradosed cable-stayed bridge
The invention discloses a stay cable construction method of an extradosed cable-stayed bridge. The stay cable construction method of the extradosed cable-stayed bridge comprises the following steps: 1, doing construction preparation work: checking and accepting a stay cable rope, allowing the stay cable rope to enter a construction site after the inspection is qualified; 2, fabricating: performingfabrication in a laid fabrication field, fabricating a stranded wire coil along the required fabrication length, then welding an HOPE sheath and installing a lower-end anchorage device; 3, cleaning apre-buried pipeline: putting an anchorage device inner core into the pre-buried pipeline from the surface, fixing the anchorage device inner core on an anchor bearing plate by using an anchor ring when the anchorage device inner core reaches the anchor bearing plate, and allowing the direction of an anchor hole to correspond to the direction of a wire distributing pipe; and 3, finally preparing abeam surface and a tower-end working platform. The construction preparation work, sleeve hoisting work, steel strand penetrating and locking, steel strand tensioning, anti-loosening device installation, accessory installation, antiseptic treatment and the like are adopted, so the installation precision and the installation quality of the stay cable are effectively guaranteed, installation is easy, and maintenance is convenient.
本发明公开了矮塔斜拉桥的斜拉索施工方法，该矮塔斜拉桥的斜拉索施工方法包括以下步骤：施工准备工作，首先对斜拉索绳进行检查验收，检查合格后方可进入工地，其次下料，在铺垫好的下料场地进行下料，沿线量好所需的下料长度，将绞线盘下料，而后焊接HOPE护套和安装下端锚具，再清理预埋管道，将锚具内芯从面预埋管放入，到达锚垫板处用锚圈固定在锚垫板上，注意锚孔方向与分丝管方向对应，最后梁面、塔端工作平台进行准备；本发明所述的矮塔斜拉桥的斜拉索施工方法，通过施工准备工作、套管吊装工作、钢绞线的穿锁、钢绞线的拉张、安装防松装置、附件安装、以及防腐处理等，有效的保证了斜拉索的安装精度和安装质量，安装简单，维修方便。
