Cable guide pipe installation method
The invention provides a cable guide pipe mounting method, and relates to the technical field of bridge construction. The cable guide pipe mounting method comprises the steps that positioning steel pipes corresponding to cable guide pipes are machined according to a preset cable bent tower structure; aiming at the cable bent tower sections to be provided with the cable guide pipe, a first section of positioning steel pipe is installed at the cable bent tower section at the lowest end to serve as a reference section; a corresponding cable guide pipe is assembled on the reference section; when each cable bent tower section is poured, concrete in the positioning steel pipe is firstly poured, and then concrete of other parts of the current cable bent tower section is poured; other positioning steel pipes serving as standard knots and corresponding cable guide pipes are additionally arranged in sequence along with construction of the cable bent tower sections. According to the embodiment of the invention, the positioning steel pipe is mounted in the cable bent tower section, the positioning steel pipe is used for assisting the positioning of the cable guide pipe, the positioning speed and precision of the cable guide pipe are improved, the possibility of generating positioning deviation after the cable guide pipe is positioned can be reduced, and the structural safety of the cable-stayed bridge is effectively protected.
本申请提供了一种索导管安装方法，涉及桥梁施工技术领域。该索导管安装方法包括：按照预设的索塔结构加工与每根索导管对应的定位钢管；针对待安装索导管的索塔节段，在最下端的索塔节段处安装首节定位钢管作为基准节；在基准节装配对应的索导管；每个索塔节段进行浇筑时，先浇筑定位钢管内的混凝土，后浇筑当前索塔节段其他部分的混凝土；随索塔节段的施工按序加设其他的作为标准节的定位钢管及对应的索导管。本申请实施例在索塔节段内安装定位钢管，利用定位钢管辅助索导管的定位，提升索导管的定位速度和精度，并且可以降低索导管在定位后，产生定位偏差的可能，有效保护索拉桥的结构安全。
