Beam bottom slope adjusting device, bridge and bridge construction method
The invention discloses a beam bottom slope adjusting device, a bridge and a bridge construction method, and relates to the technical field of bridge engineering. The beam bottom gradient adjusting device is used between a box beam and a cover beam of a bridge and comprises a support and a prefabricated padstone, the prefabricated padstone is arranged above the support, the lower surface of the prefabricated padstone has a prefabricated gradient, and the prefabricated gradient is determined according to elevation data and position data fed back by an actual bridge structure on a construction site. Compared with cast-in-place cushion stone, the slope adjusting precision of the bridge is higher, the bridge stress is more stable, meanwhile, the problems that construction risks are caused by welding of a wedge-shaped steel plate at the bottom of a box girder and deviation and adjustment are inconvenient in the construction process of welding of a steel plate embedded in the bottom of the girder are solved, and therefore the slope adjusting construction of the bridge is safer and more convenient, and the cost is lower.
本发明公开了一种梁底调坡装置及桥梁和桥梁施工方法，涉及桥梁工程技术领域。梁底调坡装置用于桥梁的箱梁和盖梁之间，梁底调坡装置包括支座和预制垫石，预制垫石设置于支座的上方，预制垫石的下表面具有预制坡度，预制坡度根据施工现场实际桥梁结构反馈的高程数据和位置数据确定，比起现场浇筑垫石精度更高，从而使桥梁的调坡精度更高，桥梁受力更稳定，同时避免箱梁底焊接楔形钢板带来的施工风险以及梁底预埋钢板焊接螺栓在施工过程中出现偏差调整不便的问题，从而使桥梁调坡施工更安全便捷，成本更低。
