∶上游引航道渥庙河排水渠通过排水渠潜孔结构和水力学设计方法，将渥庙河来流量排入上游引航道底部的同时，很好地满足了引航道内船舶、船队航行和停泊的安全要求。排水渠施工时采用预留土堤作为围堰挡水，施工简便，施工进度快。此外，相对于其它远引排泄方案，此排水渠设计方案大大减少了征地与结构工程费用。

Wumiaohe drainage canal of upstream approach channel diverts the inflows to the bottom of approach channel through the down-hole drainage canal structure and the hydraulics design methods, which well satisfies the safety requirements on ship or fleet sailing and berthing in the approach channel. Taking the reserved earth dike as the cofferdam, during the construction of the drainage cannel, greatly speeds up the construction progress and simpli-fies the construction procedures. In addition, this drainage canal, compared to other diversion schemes, greatly re-duces the cost on land acquisition and structure projects.
