山区小型水电站一般是靠修建小型渠道来集中河流落差的,因此,渠道工程量的大小,以及渗漏程度和安全与否等,都直接影响小水电站的效益。就投资而言,它占电站总投资的40～50%。因此,如何做好渠道的设计工作很重要。我们根据山区的具体条件,在实践中摸索出一些较简便的做法,兹介绍如下。 Small mountain hydropower stations generally rely on the construction of small-scale channels to concentrate river drops. Therefore, the amount of channel works, the degree of leakage and the safety or not have a direct impact on the profitability of small hydropower stations. In terms of investment, it accounts for 40-50% of the total investment in power plants. Therefore, how to do a good job of channel design is very important. Based on the specific conditions in the mountainous areas, we have found some simpler practices in practice. Here is a brief introduction.
