列宁格勒水工设计院与特种结构设计局列宁格勒水工钢结构设计院协作,进行过一系列位于高坝下游面的钢—钢筋混凝土混合结构的输水管道设计。这种管道已在克拉斯诺雅尔斯克和契尔克依斯克水电站运用。萨扬—舒申斯克水电站也作了这种管道的设计。管道布置在坝的计算剖面外。与坝内式管道相比,其优点是:不会削减下游最大应力部位的坝体,并可按机组投入运行的顺序进行施工,即可与坝体分开施工。这就使得投资不致积压,且能减轻安装工作的强度。
In collaboration with Leningrad Hydro-Steel Design Institute, Leningrad Hydro-Design Institute conducted a series of design of pipelines for steel-reinforced concrete hybrid structures located on the downstream side of high dam. The pipeline has been used in Krasnoyarsk and the Kırıkshke hydroelectric power station. Sayan - Shushenskaya hydropower station also made such a pipeline design. The pipe is arranged outside the dam’s calculated section. Compared with the dam-type pipeline, the advantages are: do not reduce the dam downstream of the maximum stress parts, and can be put into operation in accordance with the order of construction units, you can separate construction with the dam. This keeps investment backlog and reduces the intensity of installation.
