Bridge incremental launching construction method
The invention discloses a bridge incremental launching construction method. The bridge incremental launching construction method comprises the steps that S1, unit structures of a beam are assembled and spliced into a segmental beam; s2, splicing the segmental beam spliced in the step S1 and an existing beam section structure into a new beam section structure on a splicing platform in a butt joint manner; s3, the whole new beam section structure assembled in the step S2 is pushed by a certain distance in the longitudinal direction of the bridge, so that the new beam section structure can be in butt joint on the assembling platform to assemble a next section beam; the step S1 to the step S3 are cycled until all the segmental beams of the bridge are assembled and pushed to the target position; a first jack, a first dragging device, a first sliding block, a second jack, a second dragging device, a second sliding block, a third jack, a third dragging device and a third sliding block are arranged on a track beam of the assembling platform. The structure stress of the pushing support below the assembling platform can be optimized, load concentration is reduced, and the requirement for a pile foundation of the pushing support is lowered.
本发明公开了一种桥梁顶推施工方法，包括步骤：S1.将梁的单元结构组装拼接成一个节段梁；S2.在拼装平台将所述步骤S1拼装成的节段梁与已有梁段结构对接拼装成一个新的梁段结构；S3.将所述步骤S2拼装的新的梁段结构整体沿桥梁纵向顶推一段距离，使该新的梁段结构能够在所述拼装平台对接拼装下一个节段梁；循环步骤S1至步骤S3，至桥梁的各节段梁全部拼装完成并顶推至目标位置；所述拼装平台的轨道梁上设置有第一千斤顶、第一拖拉装置、第一滑块、第二千斤顶、第二拖拉装置、第二滑块、第三千斤顶、第三拖拉装置和第三滑块。本发明可优化拼装平台下方顶推支架的结构受力，减少荷载集中，降低对顶推支架的桩基要求。
