Large-span main beam bidirectional rapid incremental launching equipment system and construction method
The invention belongs to the technical field of main beam incremental launching construction in bridge construction, and particularly relates to a large-span main beam bidirectional rapid incremental launching equipment system and a construction method. The system comprises a supporting system, a power system and an accurate positioning system. The supporting system comprises stand columns, an unloading device, cross beams, longitudinal beams and distribution beams, each stand column is arranged on a pier or on a foundation between two piers, one cross beam is connected between the tops of each row of stand columns, the longitudinal beams are installed on the cross beams, the distribution beams are installed on the longitudinal beams, and a main beam is placed on the distribution beams. The power system comprises a pushing counter-force base, a jack, a deviation rectifying device, a flexible pushing device, an anchor pulling structure and a traction bundle. The accurate positioning system comprises a stand column, a stay cable and beam anchor beams, the stand column is fixed to the middle of the main beam, the beam anchor beams are installed at the two ends of the main beam respectively, and the stay cable is connected between the beam anchor beams and the top of the stand column. Construction of guide beams and the combination section of the guide beam and the main beam is omitted, and the construction quality of the main beam is ensured.
本发明属于桥梁建设中主梁顶推施工的技术领域，具体是一种大跨度主梁双向快速顶推装备系统及施工方法。包括支撑系统、动力系统和精确定位系统。支撑系统包括立柱、卸落装置、横梁、纵梁以及分配梁，立柱设置在桥墩上或两个桥墩之间的基础上，每排立柱顶部之间连接有横梁，横梁上安装有纵梁，纵梁上安装有分配梁，分配梁上放置有主梁。动力系统包括顶推反力座、千斤顶、纠偏装置、柔性顶推装置、拉锚结构以及牵引束。精确定位系统包括立柱、斜拉索以及梁部锚梁，立柱固定在主梁中部，主梁两端分别安装梁部锚梁，梁部锚梁与立柱顶部之间连接有斜拉索。本发明省去了导梁、导梁与主梁结合段施工，确保了主梁的施工质量。
