Bridge structure accumulated dragging and pushing construction mechanism and construction method thereof
The invention discloses a bridge structure accumulated dragging and pushing construction mechanism and a construction method thereof. The mechanism comprises a temporary pier supporting system which is installed in the longitudinal direction of a bridge and spans two sides of a main pier of the bridge; a slideway beam which is arranged on the main pier and the temporary pier supporting system in the longitudinal direction of the bridge; a continuous traction assembly which comprises a dragging jack, a jack reaction frame, an inhaul cable and a sliding block, wherein the dragging jack is fixedly installed at the front end of the slideway beam in the longitudinal direction of the bridge through the jack reaction frame, and the sliding block is arranged on the slideway beam in a sliding modeand connected to the moving end of the dragging jack through the inhaul cable; a vertical pushing assembly which is used for vertically pushing the bridge and is mounted on the slideway beam and the temporary pier supporting system; and a plurality of base plates which are arranged between the main pier and the bridge in a cushioning manner after the bridge is dragged and pushed in place. The problems of long cushion block transferring time, high labor cost, high risk and the like in the incremental launching construction of the bridge with the continuously changed bottom surface gradient aresolved.
本发明公开了一种桥梁结构累积拖拉顶推施工机构及其施工方法，机构包括：临时墩支撑体系，安装于桥梁纵向方向，跨于桥梁主墩两侧；滑道梁，沿桥梁纵向方向设置于所述主墩与所述临时墩支撑体系上；连续牵引组件，包括拖拉千斤顶、千斤顶反力架、拉索、滑块，所述拖拉千斤顶通过所述千斤顶反力架沿桥梁纵向方向安装固定在所述滑道梁的前端，所述滑块滑设于所述滑道梁上并通过所述拉索连接于所述拖拉千斤顶的移动端；用于竖向推顶桥梁的竖向推顶组件，安装在所述滑道梁及所述临时墩支撑体系上；用于在桥梁拖拉顶推到位后垫设于所述主墩与桥梁之间的多块垫板。解决了底面坡度不断变化的桥梁的顶推施工中垫块倒运时间长，劳动成本高，危险性大等问题。
