Construction method for erecting bridge girder erection machine through tunnel box girder
The invention provides a construction method for erecting a tunnel-passing box girder of a bridge girder erection machine, and belongs to the technical field of bridge girder erection machine construction. The construction method comprises the following steps that before the bridge girder erection machine passes through a tunnel, all supporting legs of the bridge girder erection machine are contracted and turned over, so that the width and height of the bridge girder erection machine meet the tunnel passing requirements, and a girder transporting machine is used for carrying the bridge girder erection machine to pass through the tunnel; the bridge girder erection machine is adjusted to a girder erection state after going out of the tunnel; a beam transporting machine is used for feeding beams; a bridge erecting machine is used for erecting beams; the bridge girder erection machine falls a girder, and a support on the box girder is installed in place; adjusting fulcrum counterforce; the bridge girder erection machine moves longitudinally to cross a span, and then the girder transporting machine is repeatedly used for feeding girders and the following steps are repeatedly used for continuous construction; the technical problems that an existing bridge girder erection machine is inconvenient to operate and low in construction efficiency during tunnel passing construction are solved.
本发明提供一种架桥机过隧箱梁架设施工工法，属于架桥机施工技术领域；该施工工法包括以下步骤，在架桥机过隧之前，将架桥机的所有支腿进行收缩翻转，以使架桥机宽度及高度符合过隧要求，使用运梁机驮运架桥机过隧；将架桥机在出隧道后调整至架梁状态；使用运梁机喂梁；架桥机架梁；架桥机落梁，并将箱梁上的支座安装就位；调整支点反力；架桥机纵移过跨，之后重复使用运梁机喂梁及以后的步骤进行连续施工；以解决现有的架桥机过隧道施工操作不便、施工效率低的技术问题。
