Vertical curve steel truss bridge incremental launching construction curve platform and construction device thereof
The invention relates to the technical field of bridge construction, in particular to a vertical curve steel truss bridge incremental launching construction curve platform and a construction device.The platform comprises a supporting mechanism, a sliding way beam is arranged on the supporting mechanism, the upper surface of the sliding way beam is arranged to be a curved surface, and the curved surface is matched with a bridge main truss bottom vertical curve; and a pushing system is arranged on the curved surface and is used for driving the steel truss girder to move along the curved surface. The steel truss girder slides along the curved surface of the slide way girder and is installed section by section, the steel truss girder can slide along the vertical curve of the main truss bottom of the bridge due to the fact that the line type of the curved surface is consistent with the vertical curve of the main truss bottom of the bridge, and the bottom of the steel truss girder and the curved surface of the slide way girder are always kept parallel and the vertical height difference is always kept consistent when the steel truss girder reaches an installation position or enters a next pushing workshop section. Therefore, no large height difference exists between the actual position and the pre-installation position, an ultrahigh cushion block does not need to be additionally arranged between the steel truss girder and the slide way girder to adjust the height difference, and the pushing construction difficulty and the construction risk of the steel truss girder are reduced.
本发明涉及桥梁施工技术领域，具体涉及一种竖曲线钢桁架桥顶推施工曲线平台及其施工装置，其中平台包括支撑机构，所述支撑机构上设有滑道梁，所述滑道梁上表面设置为曲面，所述曲面与桥梁主桁底竖曲线相适配，所述曲面上设有顶推系统，所述顶推系统用于带动钢桁梁沿所述曲面移动。钢桁梁沿滑道梁曲面滑动逐段安装，由于曲面的线型与桥梁主桁底竖曲线一致，使得钢桁梁能够沿桥梁主桁底竖曲线滑移，在到达安装位置或进入下一顶推工段时，钢桁梁底与滑道梁曲面始终保持平行，竖向高差始终保持一致，因此实际位置与预安装位置不会存在较大的高度差，从而不需要在钢桁梁和滑道梁之间增加超高垫块调整高差，从而降低了钢桁梁顶推施工难度和施工风险。
