沿江出海口平坦城镇雨水管道设计方法探讨

Approach about design procedures of rain-water drainage pipe for smooth terrain of the coast outlet along river

结合沿江出海口平坦地区的水文地理特点 ,提出雨水管道水力计算须按压力流考虑 ,管道水力计算的设计坡度采用水力坡降 。

Combined with the hydrographic and geographic characteristics for smooth terrain of the coast outlet along river ,here pose the hydraulic calculation of rain water pipes is according to the pressure flow,its design of gradient is according to the hydraulic gradient.and advocate that pipe coupling can adopt the design thinking and calculating method of pipe bottom's end to end joint.
