Concrete-filled steel tube arch bridge arch rib concrete pressure injection device and construction process method
The invention belongs to the technical field of bridge construction and provides a concrete-filled steel tube arch bridge arch rib concrete pressure injection device and a construction process method. The concrete pressure injection device is mainly composed of two square steel plates and a flashboard, and the flashboard is temporarily fixed through one-way bolts on the square steel plates in the concrete jacking pressure injection process; after the pressure injection of the concrete pumping equipment is completed, the one-way bolts are loosened, the flashboard is released, the flashboard is hammered into the required depth through a hammering tool, then the buckle connection between a first short pump pipe and a pump pipe is removed, the cutting-off work of a concrete conveying system at the lower end is completed, and the device is easy to manufacture, low in cost, practical and effective.
本发明属于桥梁施工技术领域，提供了一种钢管混凝土拱桥拱肋砼压注装置及施工工艺方法，该砼压注装置主要由两块方形钢板和一块闸板组成，闸板在混凝土顶升压注过程中通过方形钢板上的单向螺栓临时固定，混凝土泵送设备压注完成后，松开单向螺栓，释放闸板，再用锤击工具将闸板锤打入到要求深度后，拆除第一短泵管与泵管之间的卡扣连接，即完成了下端的混凝土输送系统的切断工作，该装置制作简单、成本低且实用有效。
