摘要:
通过对广西南宁市18条内河现状调查分析,大部分内河河道上游天然来水不能满足河道生态及景观要求,因此考虑进行生态景观补水,利用邕江上游老口水库,建设大型重力输水干渠实现上游自流补水功能。工程建成后城市的水质全面提高,总体水质达到《地表水环境质量标准》(GB 3838—2002)的Ⅲ～Ⅳ类水质标准。干渠工程建设总长为25.57 km。通过研究大型内河补水干渠的系统布局和工艺参数,创新性地提出在原有输水系统基础上进行多功能系统性利用的可行性。经过系统比较和针对性的结构安全、系统安全、水力工况计算后,大型输水干渠输水能力按照228×104 m3/d运行,兼顾了近期城市原水输水和内河补水需求,有望同时解决城市水源地建设以及城市河道黑臭问题。干渠段水力坡降约2 m,节约工程投资6亿多元,具有明显的经济效益和社会效益。
Abstract:
By analyzing the existing 18 river conditions of Nanning City, the natural water coming from the upper reaches of most inland rivers could not meet the river ecology environment and landscape rudiments. It was feasible to construct large water tunnel to transport Laokou upper zone reservoir water to supplement fresh water into city rivers. The water quality of inland rivers would be improved to Ⅲ-Ⅳ standard of Environmental Quality Standards for Surface Water(GB 3838-2002)after 25.57 km tunnel project complement. By research on the design parameters and system layout of large river supplement tunnel, it was possible and reasonable to have raw water transfer system on existing large water tunnel. The running scale of the multifunctional tunnel was 228×104 m3/d, which could meet both raw water needs for drinking water plant and river supplement requirements after proposal comparison and calculation of structure security, system safety and hydraulic conditions. As a result, the hydraulic slope in the main canal section was about 2 m, and the project investment was saved by more than 600 million yuan, which had obvious economic and social benefits.
