Continuous steel truss girder construction method for bidirectional longitudinal slope bridge deck
The invention discloses a construction method for a continuous steel truss girder of a bidirectional longitudinal slope bridge floor, and relates to the technical field of bridge engineering construction.The method comprises the steps that sliding seats arranged below bridge sections are used for sequentially and longitudinally moving all the bridge sections to design positions; and the height of the sliding seat below each bridge section is matched with the gradient of the bridge section when the bridge section longitudinally moves to a design position. A plurality of sliding seats with different heights are respectively mounted at the bottoms of different sections of the steel truss girder, so that the corners of the slope crest are buffered through the sliding seats with different heights, meanwhile, the line type of the spliced steel truss girder can be kept, and the sections are pushed to set positions through the pushing device, so that continuous construction can be realized, and the construction efficiency is improved.
本发明公开了一种双向纵坡桥面的连续钢桁梁施工方法，涉及桥梁工程施工技术领域，该方法包括：利用设置在上述桥梁节段下方的滑座，依次纵移各个桥梁节段至设计位置，每一上述桥梁节段下方滑座的高度与该桥梁节段纵移至设计位置时的坡度匹配。通过在钢桁梁的不同节段的底部分别安装多个高度不同的滑座，从而通过不同高度的滑座来缓冲坡顶的拐角，同时还可以保持拼接后钢桁梁的线型，且多个节段通过顶推装置顶推至设定位置，从而可以连续施工，提高了施工效率。
