Abstract
In order to meet the requirements of irrigation water temperature,water supply quality and the downstream water ecologic development of reservoir,the adoption of multi-level intake measure is gradually required for some medium-large scaled water resources projects at present.Through the comparison made among the merits and defects of conventional multi-level intake structures,a new type of the multi-level intake structure is designed,which has the characteristics of concise hydraulic structure,simple control equipment,convenient operation mode,lower construction cost,etc.The shape of the new type of multilevel intake structure is optimized in accordance with the hydraulic structure of the multi-level intake with stoplog gate,and then a new type gate is innovatedly designed in combination with the characteristics of the water intake on pontoon and the control equipment of the inclined horizontal gate-taking semi-circular conjoined gate and series connection plane gate as the control equipment.Through the relevant model experiment,the feasibility of the application of the new type water intake is verified,while it is actually applied to the reconstruction project of Yutan Reservoir in Chongqing,from which better economic and social benefits are obtained as well.At present,the new type multi-level intake structure can take the surface warm water under the conditions of any water levels in medium scaled water resources projects,thus it is necessary to take how to reasonably apply this water intake structure to the large scale water resources project as the direction of the emphasized study in the next step.关键词
