Chord pipe pumping mechanism, pumping process and arch bridge main arch concrete inner pouring device
The invention relates to the technical field of steel arch bridge construction, and discloses a string pipe pumping mechanism, a pumping process and an arch bridge main arch concrete inner pouring device.The string pipe pumping mechanism comprises a first main pipeline, a first reversing valve, a first branch pipe and a second branch pipe; the first main pipeline is communicated with a conveying pump, the first reversing valve is provided with a group of input ports and two groups of output ports, and the input ports of the first reversing valve are communicated with the first main pipeline; the output end of the first branch pipe is communicated with the part of the chord pipe on the arch foot side of the arch bridge, and the input end is communicated with one group of output ports of the first reversing valve; the output end of the second branch pipe is communicated with the part, located between the arch foot side and the arch crown side of the arch bridge, of the chord pipe, the input end of the second branch pipe is communicated with the other set of output ports of the first reversing valve, and the output end of the first branch pipe and the output end of the second branch pipe are each provided with a stop valve. The arch bridge main arch concrete inner pouring device comprises the chord pipe pumping mechanism and the stand column pumping mechanism which are similar in structure, the complexity of arrangement of main arch concrete inner pouring pipelines is reduced, and the construction efficiency is improved.
本发明涉及钢拱桥施工技术领域，公开了一种弦管泵送机构、泵送工艺及拱桥主拱混凝土内灌装置，其中，弦管泵送机构包括第一主管道、第一换向阀、第一支管及第二支管；第一主管道连通有输送泵，第一换向阀具有一组输入口及两组输出口，第一换向阀的输入口与第一主管道连通；第一支管输出端与弦管位于拱桥拱脚侧的部分连通，输入端与第一换向阀的一组输出口连通；第二支管输出端与弦管位于拱桥的拱脚侧与拱顶侧之间的部分连通，输入端与第一换向阀的另一组输出口连通，第一支管的输出端及第二支管的输出端均设有截止阀；拱桥主拱混凝土内灌装置包括结构相似的弦管泵送机构及立柱泵送机构，减少了主拱混凝土内灌的管路的布置的复杂性，提升施工效率。
