- 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.
