“海绵城市”理念在集装箱堆场的应用探讨

Application of Sponge City Concept in Design of Container Yard

集装箱码头堆场地表雨水都是通过径流,经排水沟、集水井收集后,流经排水管从码头前方直排进海里,造成水资源的浪费。将“海绵城市”设计理念和方法具体应用到集装箱码头堆场设计中,一方面通过雨水渗透、净化和涵养,减少雨水外排量,避免水资源浪费,另一方面减少雨水溢流量,进而可以把雨水管道管径减小,从而降低工程造价。

Surface rainwater in container yard is generally runoff,which is collected through drainage ditches and catchment wells,and discharged directly into sea through the drainage pipes at wharf apron,the above process results in the waste of water resources.The concept and method of Sponge City should be applied in the design of container yard.On the one hand,it reduces the discharging volume of rainwater and avoids the waste of water resources by filtering,purifying and conserving rainwater;on the other hand,it reduces the overflow of rainwater.In addition,the diameter of rainwater pipes may be reduced to lower the construction cost.
