Ⅰ.水工建筑物的作用水工建筑物是实现国家水利事业,如河川的水能利用,兴建航道、灌溉田地,保证居民和工业及运输的用水,防洪和防止水的破坏作用等的一种工具。为实现这些措施就必须调节河川的径流,在河流上设法抬高水位以利航运、灌溉和发电;必要时还需要降低河水流速,减少含砂量,并利用渠道、管道等引水和排水。
Ⅰ. The Role of Hydraulic Structures Hydraulic structures are one of the most important water conservancy projects in the country, such as water energy utilization in rivers, waterway construction, irrigated fields, water for residents, industrial and transportation, flood control and water damage prevention Kind of tools. In order to realize these measures, it is necessary to regulate the runoff of rivers and try to raise the water level on the rivers to facilitate shipping, irrigation and power generation.
