浅谈茶坑水库分层取水方案设计

Discussion on the design of stratified water intake scheme for Chakeng Reservoir

对茶坑水库建成后的水温结构和垂向水温分布进行计算预测,通过对照同类水库分层水质变化规律,从满足优质原水供应和解决灌溉水温方面对稳定分层型水库分层取水方案进行了简要分析。从设计角度介绍了茶坑水库的竖井式分层取水方案,该取水方案对现有分层取水结构进行了优化改进,可较好地满足供水、灌溉和生态环境对水库水温水质的要求。

This paper calculates and predicts the water temperature structure and vertical water temperature distribution after the completion of Chakeng Reservoir by comparing the changing law of stratified water quality of similar reservoirs.The stratified water intake scheme of stable stratified reservoir is briefly analyzed from the aspects of satisfying high quality raw water supply and solving irrigation water temperature.From the point of view of design,the vertical stratified water intake scheme of Chakeng Reservoir is introduced,which optimizes and improves the existing layered water intake structure,and can better meet the requirements of water supply,irrigation and ecological environment for reservoir water temperature and water quality.
