前言 随着海水养殖业的发展,潮汐作为一种天然能源已越来越广泛地应用于养殖池的水体交换,尤其在沿海滩涂的对虾养殖生产中。换水量是养殖生产管理中一个重要因素,而进水闸直接控制着换水量。由于在换水过程中外潮位和地内水位都在不断变化,无法直接使用目前水利工程中的闸门流量计算方法,各地养殖地的进水闸门宽度和流量都无法计算,只能借鉴和估计。如1979年某地在一个虾场的建设中,进水闸估计了15孔,每孔宽2米,单孔造价数
INTRODUCTION With the development of mariculture, tides have been increasingly used as a natural source of energy for the exchange of water in ponds, especially in coastal shrimp farming. Water exchange is an important factor in the management of aquaculture production, while the floodgates directly control the water exchange. As the water level during the water changing process is constantly changing, it is impossible to directly use the current gate flow calculation method in water conservancy projects. The width and flow of the inlet gate in the breeding areas can not be calculated and can only be used for reference and estimation. For example, in 1979, in a shrimp farm construction, the intake was estimated 15 holes, each hole width of 2 meters, single-hole cost
