地下水库在海绵城市建设中的应用

Application of underground reservoirs in construction of sponge cities

为探讨地下水库系统工程在海绵城市建设中的应用模式,在介绍地下水库的概念、分类和国内外工程实践的基础上,通过阐述海绵城市的内涵和要求,地下水库应用于海绵城市建设中的优势及地下水库调蓄、净化、水循环路径等基本原理,论证了地下水库系统应用于海绵城市建设的可行性。基于海绵城市的"渗、滞、蓄、净、用、排",设计了囊括地表拦蓄、陆域雨水收集、补源、地下蓄水、取水、泄水、污水排放及处理、中央监控等八大系统为主体的地下水库系统工程整体架构。

To explore the practical application modes of underground reservoir system engineering in sponge city construction,the concepts, classifications and engineering practice on underground reservoirs at home and abroad were reviewed. The connotation and request of a sponge city, the advantages of underground reservoirs in sponge city construction and the basic principles of regulation, purification and water cycle path were presented. The feasibility of underground reservoir system in the application of sponge city construction w,as also demonstrated. Based on the key principles in sponge city construction, such as infiltration, detention, storage, purifying, and drainage, an overall structure of an underground reservoir system engineering was designed. The overall structure consists of eight systems, including surface water impoundment, land rainwater collection, recharge, groundwater storage, water intaking, water discharge, wastewater discharge and treatment, and central monitoring projects.
