北溪引水主干渠改造平面方案比选及水力计算

摘要:

本文基于北溪引水主干渠改造中灌新路节点形式提出三种平面布置方案,通过渠线选择、水力计算、造价等方面的比选可知利用现状箱涵过灌新路隧道使得水头损失较小、不占用地块、对4号线影响较小,结合其他因素确定改造工程选线平面方案,进行新旧箱涵水力复核计算,为类似工程提供参考。

Abstract:

Based on the node form of Guanxin road in the reconstruction of Beixi diversion main canal, this paper puts forward three plane layout schemes. Through the comparison of canal line selection, hydraulic calculation and cost, it can be known that the current box culvert is used to pass through the tunnel of Guanxin road so that the water head loss is small, the land is not occupied and the influence on Line 4 is small. Combined with other factors, the line selection plan of the reconstruction project is determined. Carry out hydraulic recheck calculation of new and old box culverts to provide reference for similar projects.
