工程概况金水河渠道倒虹吸工程位于郑州市二七区齐礼阎乡黄岗寺村西约300 m处,属沙河南—黄河南郑州2段设计单元中的河渠交叉工程。金水河渠道倒虹吸由进口渐变段、进口检修闸、倒虹吸管身段、出口节制闸和出口渐变段组成。倒虹吸进口渐变段起点桩号为总干渠SH(3)195+721.2,出口渐变段终点桩号为总干渠SH(3)196+085.2,建筑物总长364 m,其中管身水平投影总长1 95 m。倒虹吸设计流量295 m~3/s,加大流量355 m~3/s。倒虹吸管身横向为4孔箱形钢筋混凝土结构,单孔孔径7 m×6.75m(宽×高)。
Project overview Jinshui River channel siphon project is located in Zhengzhou City Erqi Qi Yan Huang Huang Temple Village about 300 m west of Shahe Nan - Yellow River Henan section of the second unit of the river channel cross engineering. Jinshui channel inverted siphon imports from the gradient section, the import gate repair, inverted siphon figure section, export control gate and exit gradient section. Inverted siphon inlet gradient section starting station for the main canal SH (3) 195 +721.2, the end of the exit gradient section station for the main canal SH (3) 196 +085.2, the total length of 364 m buildings, including the total length of the tube projection level 1 95 m. Inverted siphon design flow of 295 m ~ 3 / s, increase the flow of 355 m ~ 3 / s. Inverted siphon body transverse 4-hole box-shaped reinforced concrete structure, single hole diameter 7 m × 6.75m (W × H).
