水下混凝土浇筑在水下指?ú课恢苯咏街炷恋氖┕し椒āＵ庵址椒ㄖ皇视糜诰菜蛄魉傩〉乃魈跫隆ＫＳ糜诮街?围堰、混凝土防渗墙、墩台基础以及水下建筑物的局部修补等工程。水下混凝土浇筑的方法很多，常用的有导管法、压浆法和袋装法，以导管法应用最广。①导管法浇筑时,将导管装置在浇筑部位。顶部有贮料漏斗,并用起重设备吊住，使可升降。开始浇筑时导管底部要接近地基面，下口有以铅丝吊住的球塞，使导管和贮料斗内可灌满混凝土拌和物，然后剪断铅丝使混凝土在自重作用下迅速排出球塞进入水中。浇筑过程中，导管内应经常充满混凝土，并保持导管底口始终埋在已浇的混凝土内。一面均衡地浇筑混凝土,一面缓缓提升导管,直至结束(如图)。采用导管法时，骨料的最大粒径要受到限制，混凝土拌和物需具有良好的和易性及较高的坍落度。如水下浇筑的混凝土量较大，将导管法与混凝土泵结合使用可以取得较好的效果。②压浆法是在水下清基、安放模板并封密接缝后，填放粗骨料，埋置压浆管，然后用砂浆泵压送砂浆，施工方法同预填骨料压浆混凝土（见混凝土施工）。③袋装法是将混凝土拌和物装入麻袋到半满程度，缝扎袋口，依次沉放，堆筑在水中预定地点。堆筑时要交错堆放，互相压紧，以增加稳定性。有的国家使用一种水溶性薄膜材料的袋子，柔性较好，并有助于提高堆筑体的整体性。在浇筑水下混凝土时，水下清基、立模、堆砌等工作均需有潜水员配合作业。
