Assembling construction method of bridge girder erection machine in different span areas and bridge girder erection machine
The invention relates to the technical field of bridge engineering construction, in particular to an assembling construction method of a bridge girder erection machine in different span areas and the bridge girder erection machine. The method comprises the following steps that temporary supports are installed on Pn + 1 piers and Pn + 2 piers in a small-span area through lifting equipment located in the small-span area; large-section longitudinal beams are spliced on the temporary supports of the Pn + 1 piers and the Pn + 2 piers section by section; a crown block assembly is installed on the large-section longitudinal beam, and temporary supports are installed on the piers located in the large-span area through the crown block assembly; and the large-section longitudinal beams are driven to move in the small mileage direction, and the small-section longitudinal beams are assembled at the ends, located in the small-span area, of the large-section longitudinal beams section by section to form longitudinal beam assemblies, so that the longitudinal beam assemblies are supported on the piers in the small-span area and the large-span area at the same time. The method solves the problem of installation of the bridge girder erection machine under the construction working conditions that bridges are connected and spans are different, and the needed assembly difficulty is small.
本申请涉及桥梁工程施工技术领域，具体涉及一种不同跨度区域架桥机的拼装施工方法及架桥机。方法包括以下步骤：利用位于小跨度区域的起吊设备在小跨度区域的Pn+1桥墩和Pn+2桥墩上安装临时支撑；在Pn+1桥墩和Pn+2桥墩的临时支撑上逐段拼装大段纵梁；在大段纵梁上安装天车总成，并利用天车总成在位于大跨度区域的桥墩上安装临时支撑；驱使大段纵梁向小里程方向移动，并在大段纵梁位于小跨度区域的一端逐段拼装小段纵梁以形成纵梁总成，以使纵梁总成同时支撑于小跨度区域和大跨度区域桥墩上。该方法解决了桥桥相连且跨度不同的施工工况条件下架桥机安装的难题，其所需拼装难度较小。
