Positioning and mounting method for super-long cable guide pipe steel anchor box of cable-stayed bridge
The invention discloses a positioning and mounting method for a super-long cable guide pipe steel anchor box of a cable-stayed bridge, which comprises the following steps that cable guide pipe groups are prefabricated, and each cable guide pipe group consists of two cable guide pipes; two pieces of vertical angle steel are arranged in the vertical direction at the cable bent tower position where the cable guide pipe set is to be installed; after the lower pipe sections of the two cable guide pipes are hoisted to the designed installation positions and the positions are preliminarily aligned, the lower pipe sections of the two cable guide pipes are fixed to the angle steel; the lower pipe sections of the two cable guide pipes are connected and fixed through a connecting pipe; the pre-buried section of the lower pipe section of the cable guide pipe and the corresponding section of cable bent tower are poured together, and the pouring elevation meets the requirement that the bottom elevation of the first section of steel anchor box is located at the installation height; and the first section of steel anchor box is hoisted to the tower top, and the upper pipe section of the cable guide pipe and the lower pipe section of the cable guide pipe are connected into a whole through a top flange plate. Separated installation of the cable-stayed bridge cable tower steel anchor box and the cable guide pipe can be achieved, investment is low, and progress and quality safety are guaranteed.
本发明公开了一种用于斜拉桥超长索导管钢锚箱定位安装方法，包括以下步骤：预制索导管组，每一个索导管组由两个索导管组成；在待安装索导管组的索塔位置处分别沿竖直方向设置两根竖向角钢；将两根索导管的下部管段分别吊装至设计安装位置并初步调正位置后，将两根索导管的下部管段分别固定在角钢上；将两个索导管的下部管段通过连接管连接固定；将索导管的下部管段的预埋段与对应节段索塔浇筑在一起，浇筑高程满足使首段钢锚箱底高程坐落在安装的高度；将首段钢锚箱吊装至塔顶，将索导管的上部管段和索导管的下部管段通过顶部法兰盘连成整体。可实现斜拉桥索塔钢锚箱与索导管分离安装，投入低、进度、质量安全有保障。
