Example Embodiment

[0018] Embodiment: This embodiment is applied to the pedestrian landscape bridge project in Xiangfen County. The whole bridge is divided into four spans with a total length of 203.47m. The bridge deck is a curved steel box girder. Stay cables are hung between the main tower and the steel box girder.

[0019] 2.1. Project introduction

[0020] Xiangfen County Pedestrian Landscape Bridge is located in the center of Xiangfen County. It is the key and highlight project in Xiangfen County's Fen River governance project. After completion, the landscape bridge will become a landmark of Xiangfen County. The bridge is divided into four spans with a total length of 203.47m. The structure of the pedestrian landscape bridge in Xiangfen County is a cable-stayed bridge and a beam bridge combined bridge. The abutment adopts reinforced concrete pile-column abutment, the bridge pier adopts reinforced concrete thin-walled pier, and the main tower foundation is a group pile foundation under the cap...

Abstract

The invention relates to a spatial stay-cable positioning method of a multispan continuous S-shaped landscape bridge, which belongs to the building field, and the method is characterized in that a central calibrator is used for positioning a central point of an anchor bearing plate on an anchoring end of a stay cable and a central point of an outlet of the stay cable, i.e. the central line of the anchor bearing plate is overlapped with the central line of the central calibrator, the central position of the anchor bearing plate is determined, and the central calibrator is a circular steel plate with the diameter which is identical to the inner diameter of a stay cable conduit; the a semicircular central calibrator is vertical to a bushing of the stay cable conduit which is previously calibrated and plugged into an outer opening of the bushing by utilizing the calibration of the semicircular central calibrator for the center of the outlet of the stay cable conduit on the outer side of an S-shaped landscape bridge main tower wall, the arc edge and the center of the semicircular central calibrator is are matched with the inner wall of the bushing, and the central position of the outlet of the stay cable conduit on the outer side of the S-shaped landscape bridge main tower wall can be obtained; and the semicircular central calibrator is a semicircular steel plate with the diameter being identical to the inner diameter of the stay cable conduit. The positioning method is high in precision and fast in speed.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a space stay cable positioning method for a multi-span continuous "S"-shaped landscape bridge. Background technique [0002] The cable-stayed bridge is a stable spatial load-bearing structural system formed by the joint stress of the main tower, cable-stayed cables, cable towers and steel box girder vertical and horizontal connections. In this spatial structure system, the cable-stayed cable is the link connecting the steel box girder and the cable tower, which makes the steel box girder a multi-point elastic support, makes the cable-stayed bridge similar to a multi-span continuous beam, and greatly reduces the size of the steel box girder. At the same time, the self-weight and live load of the steel box girder transmit the cable force to the main tower through the stay cables. Due to the symmetrical distribution of the stay cables, the cable tower and the steel box girder...
