Partitioned flood storage system with city flood and flood coexistence
The invention discloses a city and flood coexistence subarea flood storage system which comprises a city flood storage area, a natural water system and a plurality of communicated river channels. The urban flood storage area is divided into a plurality of flood storage subareas by watersheds, each flood storage subarea is divided into a non-submerged area and a submerged fortification area from the periphery to the center, and the terrains of the watersheds, the non-submerged areas and the submerged fortification areas are arranged from high to low. The natural water system is located on the outer side of the urban flood storage area, and the natural water system is a river channel communicated with an urban flood drainage system. And each communicating river channel is perpendicular to the natural water system and penetrates through the adjacent flood storage subarea, and the communicating river channels are connected with the natural water system and the submerged fortification area penetrating through the flood storage subarea. By arranging the flood storage subareas, extra-heavy rainfall is guided to be dispersed and gathered in the flood storage subareas, the whole flood is broken up into parts, coexistence of local or all areas of a city and the flood is achieved, and personnel safety and property losses caused by flood disasters are reduced.
本发明公开了一种“城洪共存”的分区蓄洪系统，其包括：城市蓄洪区、自然水系和多个连通河道。所述城市蓄洪区被分水岭分隔为多个蓄洪分区，所述蓄洪分区由四周至中央分为非淹没区与淹没设防区，所述分水岭、所述非淹没区和所述淹没设防区的地势由高到低排列。所述自然水系位于所述城市蓄洪区的外侧，所述自然水系为连通城市排涝系统的河道。每一所述连通河道垂直于所述自然水系并穿过相邻所述蓄洪分区，所述连通河道与自然水系以及贯穿的所述蓄洪分区的所述淹没设防区相连接。通过设置蓄洪分区的方式，从而引导特大降雨分散汇聚于各蓄洪分区，将洪水化整为零，实现城市的局部或全部区域与洪水共存，减小洪水灾害造成的人员安全与财产损失。
