围堰围堰cofferdam围护水工建筑物施工场地，使免受河水影响的临时挡水建筑物。围堰要求施工简单，维护容易，拆除方便，并能满足稳定、防渗、抗冲及一定强度的要求。按与水流方向的相对关系，分为垂直河流方向的横向围堰和平行河流方向的纵向围堰。按是否允许过水，分为过水围堰和不过水围堰。按修建所用材料划分，常用的有土石围堰与混凝土围堰，还有草土围堰、板桩围堰，以及木笼、竹笼或铅丝笼装石围堰等。土石围堰就地取材、结构简单、施工方便，对地基要求较低，故被广泛采用，又分土围堰、土石混合围堰和堆石围堰。混凝土围堰需在岩基上采用，其断面小，占地少，抗冲防渗性能好，堰顶可以过水。板桩围堰有钢板桩、木板桩和钢筋混凝土板桩等形式，可布置成单排、双排或格形体，各有其使用条件。木笼装石围堰可抗4～6米/秒流速，堰顶浇筑混凝土板后可以溢流，可在岸上预制、水上沉放，施工较快，但木材耗用多，拆除不便，现已很少使用。竹笼装石围堰和铅丝笼装石围堰多在中小型工程或局部地段使用。草土围堰是中国黄河流域传统的围堰结构、层土层草，可在流速2～3.5米/秒流水中修筑，挡水高度一般不超过6米。它构造简单，施工方便，拆除容易，但草料用量大，沉陷量较大，草料易腐烂，使用期一般不超过两年。
