立体交叉道路排水问题分析及治理——以宿迁市深圳路立交桥排水为例

Analysis and Treatment of Drainage Problem of Interchange Roads--Taking the Drainage of Shenzhen Road Overpass in Suqian City as an Example

立交下穿道路极大地缓解了城市交通压力,然而城市下穿道路易于积水的问题也日益突出,因此立交道路排水系统至关重要。文章以宿迁市深圳路的立交下穿道路排水系统改造设计为例,详细介绍了立交下的深圳路积水原因,立足于改善立交下穿道路排水设计,主要分析了泵站设计、收水系统设计、出水系统设计的要点及难点。经过立体思维通盘考虑整个立交系统的排水问题,有效截流高处雨水,及时排出低处雨水,对类似工程具有一定借鉴意义。

Interchange underpass roads greatly alleviate the urban traffic pressure.However,the problem of water accumulation on urban underpass roads is becoming more and more prominent.Therefore,the drainage system of interchange roads is very important.Taking the reconstruction design of the interchange underpass road drainage system of Shenzhen Road in Suqian City as an example,the causes of water accumulation on Shenzhen Road under the interchange are introduced in detail.Based on the improvement of the drainage design of the interchange underpass roads,the key points and difficulties in the design of pump station,water collection system and water outlet system are mainly analyzed.Through the three-dimensional thinking,the drainage problem of the whole interchange system is considered comprehensively,and the rainwater at the high altitude is effectively intercepted and the rainwater at the low altitude is discharged in time,which has certain reference significance for similar engineering.
