Long-span steel-concrete composite beam long-distance incremental launching construction system
The invention discloses a long-span steel-concrete composite beam long-distance incremental launching construction system which is characterized in that a steel-concrete composite beam is erected on apier with a U-shaped pier top, and bridge supports are arranged at two U-shaped ends of the pier top; the incremental launching construction system comprises incremental launching equipment arrangedin a pier top concave area and a bearing beam arranged between the incremental launching equipment and the steel-concrete composite beam. The bearing beam is of a big-end-up structure, the upper portion of the bearing beam is connected with the beam bottom plate, and the lower portion of the bearing beam is supported by the incremental launching equipment. According to the invention, the permanentpier is used as a supporting point of the incremental launching equipment, the concave area of the pier top U-shaped structure is used as a working platform of a walking type jack, so that temporarypiers are not needed, and the problem that large-scale equipment cannot enter the shallow water sea area with large steel demand can be solved.
本发明公开了一种大跨度钢混组合梁长距离顶推施工系统，所述钢混组合梁架设于墩顶呈U型的桥墩上，墩顶U型两端上设有桥梁支座；所述顶推施工系统包括设于墩顶凹陷区域内的顶推设备，以及设于所述顶推设备与所述钢混组合梁之间的承载梁；所述承载梁呈上大下小结构，上部与梁底板相接，下部支撑于所述顶推设备。本发明中，以永久桥墩作为顶推设备支撑点，即以墩顶U型结构的凹陷区域为步履式千斤顶工作平台，无需设置临时墩，能够解决浅水海域钢材需求量大但大型设备又无法进入的问题。
