Combined support for arch-to-ring arch reinforcement construction of river-crossing bridge and erecting method of combined support
The embodiment of the invention relates to a combined support for reinforcing construction of an arch ring and an arch of a river-crossing bridge and an erecting method. The combined support comprises a plurality of sets of longitudinal stress distribution beams, a middle supporting structure and a plurality of transverse stress distribution beams, wherein the two ends of the longitudinal stress distribution beams are erected on the two abutment foundations below the arch ring respectively, the middle supporting structure is used for supporting the middles of the sets of longitudinal stress distribution beams, and the transverse stress distribution beams are laid on the sets of longitudinal stress distribution beams at the same time. The all-round scaffolds are erected on the transverse stress distribution beams; the ends, located on the same side, of all the transverse stress distribution beams extend out of the same closest set of longitudinal stress distribution beams by a distance not smaller than a preset distance, bearing plates are laid on the portions, extending out of the same closest set of longitudinal stress distribution beams, of all the transverse stress distribution beams, and protective fences are arranged to form the construction temporary bridge. The combined support is suitable for arch ring and arch sleeving reinforcing construction of a river-crossing bridge with the deep water level, the riverbed surface being a rock surface and the requirement for guaranteeing normal water flow of a river.
本发明实施例涉及用于跨河道桥梁拱圈套拱加固施工的组合支架及搭设方法。所述组合支架包括多组两端分别搭设于拱圈下方的两墩台基础上的纵向受力分配梁，对各组纵向受力分配梁中部进行支撑的中部支撑结构，同时铺设于各组纵向受力分配梁上的若干横向受力分配梁，搭设于横向受力分配梁上的满堂脚手架；各所述横向受力分配梁位于同一侧的一端均伸出同一最近的一组纵向受力分配梁不小于预设距离，各所述横向受力分配梁的该伸出同一最近的一组纵向受力分配梁的部分铺设承载板件，以及设置防护栏以形成施工便桥。所述组合支架，适用于对水位深，河床表面为岩面，且需保证河道正常水流的跨河道桥梁拱圈套拱加固施工。
