摘要：在全国耕地减少、建设用地日趋紧张的背景下,滩涂是非常可贵的战略资源.处于淤涨中的淤泥海岸滩涂,在一定条件下是可再生资源.现在盘锦市大洼县有一块沿海的滩涂,对其进行改造,将长久以来遭受海水侵蚀的此块滩涂改成水田,进行水稻种植.
首先修筑拦潮坝将海水拦截,但由于滩涂西面有海水养殖场,因此还要修建纳潮沟.其次在滩涂北部修建提水泵站,从混江沟西排总取水,用于对滩涂地块淡水洗盐和灌溉供水.进行泵站设计需要选泵、并对泵房的形式和结构进行设计.最后规划灌溉排水渠系,使该滩涂改成水田后,旱可灌水,涝可排水,尽量是水稻在良好的环境下生长.规划灌排渠系需要设计渠系总体布置,然后根据选定的灌水模数计算各级渠道的设计流量,再设计各级渠道的横、纵断面；设计排水沟系,设计够系的总体布置,计算各级沟道的排涝流量、排渍流量,设计沟道的横、纵断面.

Accretion of silt in coastal mudflats, under certain conditions, is a renewable resource. Dawa County of Panjin City, now has a coastal beach, its transformation, will suffer from water erosion of long beach this block into paddy fields for rice cultivation. The first wave of dam construction stopped seawater interception, but because the west beach marine farms, so also the construction of tidal ditch. Second, in the construction of the northern beaches to mention pumping station ditch west row from the total mixed river water, used to wash the salt and freshwater tidal land irrigation water. Selecting a pump for pumping station design needs, and the form and structure of the pumping station design. Final planning irrigation and drainage canal, so that the shoals into paddy fields, the drought can be irrigation, waterlogging can be draining, so far as is rice grown in a good environment. Canal irrigation canal planning to design general layout, and then according to the selected irrigation channels Modulus design flow at all levels, and then cross-channel design levels, longitudinal; gutter system design, design of the overall layout of the Department enough calculated levels of drainage channel flow, Underground Drainage flow channel design horizontal, vertical section. Keywords: beach transformation; pumping station design; design of irrigation and drainage canal
