Cable-stayed bridge concrete beam cable guide pipe construction method
The invention discloses a cable-stayed bridge concrete beam cable guide pipe construction method which comprises the following steps: calculating three-dimensional coordinates of an anchoring point of an inhaul cable anchor block and a pipe top center on a local coordinate system on the basis of relative coordinates and angle data of the inhaul cable anchor block in an overall arrangement table to obtain a calculated coordinate value; based on a building information model technology, carrying out three-dimensional modeling on a cable bent tower and a box girder end cable guide pipe of the target cable-stayed bridge, and determining simulation coordinate values of an anchoring point of a cable anchor block and a pipe top center in a building information model; based on the calculated coordinate values and the simulated coordinate values, target coordinate values of the anchoring point of the inhaul cable anchor block and the center of the pipe top are determined; based on the target coordinate value, lofting and fixing construction are conducted on the inhaul cable anchor block; before concrete is poured, the beam end of the stay cable anchor block and the axis of the tower end cable guide pipe are rechecked through the laser irradiation target, and the stay cable guide pipe is fixed. The cable guide pipe can be accurately installed, and the installation quality of the cable-stayed bridge is ensured.
本发明公开了一种斜拉桥混凝土梁索导管施工方法，包括：基于拉索锚块在总体布置表中的相对坐标和角度数据，计算拉索锚块的锚固点和管顶中心在局部坐标系上的三维坐标，得到推算坐标值；基于建筑信息模型技术，对目标斜拉桥的索塔和箱梁端索导管进行三维建模，并确定拉索锚块的锚固点和管顶中心在建筑信息模型中的模拟坐标值；基于推算坐标值和模拟坐标值，确定拉索锚块的锚固点和管顶中心的目标坐标值；基于目标坐标值，将对拉索锚块进行放样及固定施工；在混凝土浇筑前，利用激光照射靶复核拉索锚块的梁端与塔端索导管轴线，固定斜拉索导管。本发明能精准安装索导管，确保斜拉桥的安装质量。
