Cable-stayed bridge tower column cable guide pipe mounting method
The invention discloses a cable-stayed bridge tower column cable guide pipe mounting method, which comprises the following steps: S1, a preformed hole template is manufactured according to the structural size of a cable guide pipe, and a chiseling-free grout stop belt coats the template; s2, after steel bars of the to-be-constructed tower column section are installed, a preformed hole formwork is installed, and the preformed hole formwork is fixed through a stiff framework; s3, concrete of the to-be-constructed tower column section is constructed, the preformed hole formwork is dismantled, and a preformed hole is obtained; s4, the cable guide pipe is hoisted and installed in the reserved hole, the cable guide pipe is positioned, and the cable guide pipe is fixed through a stiff framework after being positioned; s5, a sealing formwork is installed, and a cavity between the cable guide pipe and the preformed hole is filled with filling concrete. According to the cable guide pipe installation method, the problems that the position is difficult to adjust and position is difficult when the cable guide pipe is directly installed are solved; the cable guide pipe installation space position precision is high, positioning is accurate, the installation time is saved in the whole process, benefits are obvious, the construction progress of the whole bridge tower can be accelerated, and the construction efficiency is improved; and meanwhile, the safety risk of installation operation is reduced.
本发明公开了一种斜拉桥塔柱索导管的安装方法，包括以下步骤：S1、根据索导管结构尺寸制作预留孔模板，包裹免凿毛止浆带；S2、完成待施工塔柱节段钢筋安装后安装预留孔模板，预留孔模板利用劲性骨架进行固定；S3、施工待施工塔柱节段的混凝土，拆除预留孔模板，得到预留孔；S4、将索导管吊装并安装在预留孔内，对索导管进行定位，定位后用劲性骨架固定；S5、安装封口模板，用填充混凝土灌注索导管与预留孔之间的空腔。本发明采用的索导管安装方法避免了直接安装索导管位置调整难，定位难的问题，安装索导管空间位置精度高，定位准确，整个过程节约安装时间，效益明显，能加快整体桥塔的施工进度，提高施工效率，同时降低安装作业安全风险。
