《水力发电》1983年第11期刊登了曹其忠同志的“修建山区小水电站渠道的简易方法”一文,文中介绍的方法确有很多优点,多年来我们也在采用,并称之为“先抄平台后挖沟法”。在采用这种方法的同时,我们还通过简易查表法设计小水电站引水渠道的横断面尺寸。实践表明,这种简易查表法对缺少技术人员的地区很适用,现介绍如后,作为对曹文的补充。 “Hydropower” No. 11 of 1983 published Comrade Cao Qizhong, “a simple way to build channels for small hydropower stations in mountain areas,” the article describes the method does have many advantages, over the years we are also using, and called “the first copy of the platform After trenching method. ” In parallel with this approach, we also designed the cross-sectional dimensions of diversion channels for small hydropower stations through a simple look-up table. Practice shows that this simple look-up method is suitable for areas lacking in technical personnel and is now introduced as a supplement to Cao Wen.
