Precise incremental launching construction method for curved steel box girder crossing existing high speed
The invention discloses an accurate incremental launching construction method for a curved steel box girder crossing an existing high speed, which comprises the following steps of: firstly, constructing a temporary buttress along a designed incremental launching line, and installing an incremental launching device on the temporary buttress; hoisting the curved steel box girder to the temporary buttress; hoisting a front guide beam to the front of the pushing direction of the curved steel box beam, and connecting the front guide beam with the curved steel box beam; the tail beam is hoisted to the rear portion of the pushing direction of the curved steel box beam, and the tail beam is connected with the curved steel box beam; the curved steel box girder is pushed forward through a pushing device until the front end of the curved steel box girder crosses the existing high speed to a preset position; a slideway is installed on the temporary buttress, a traction device is installed on the offset side of the curved steel box girder, and the traction device is connected with the curved steel box girder; starting a traction device to pull the curved steel box girder to slide to a designed position along the slide way; and dismantling the temporary buttress, the slideway, the traction device and the pushing device. The method has the effect of improving the construction efficiency and the positioning precision of the curved steel box girder crossing the existing high speed.
本申请公开了一种跨既有高速的曲型钢箱梁精确顶推施工方法，先沿设计的顶推线路施工临时支墩，并在临时支墩上安装顶推装置；吊装曲型钢箱梁至临时支墩上；吊装前导梁至曲型钢箱梁的顶推方向的前方，并将前导梁连接曲型钢箱梁；吊装尾梁至曲型钢箱梁的顶推方向的后方，并将尾梁连接曲型钢箱梁；通过顶推装置将曲型钢箱梁顶推前进，直至曲型钢箱梁的前端跨过既有高速至预设位置；在临时支墩上安装滑道，在曲型钢箱梁的偏移侧安装牵引装置，将牵引装置连接曲型钢箱梁；启动牵引装置，牵引曲型钢箱梁沿滑道滑移至设计位置；拆除临时支墩、滑道、牵引装置和顶推装置。本申请具有提高曲型钢箱梁跨过既有高速的施工效率以及落位精度的效果。
