摘　　要：整体式钢套箱围堰效率低、成本高。针对湘江长沙综合枢纽船闸工程水中100多个墩台的施工任务,设计了一种新型预应力组合式钢套箱——用施加了预应力的钢丝绳将分片式钢套箱组合成有机整体,因此将钢套箱的全部操作由水下转为水上。现已完成120个水中多种形状墩台的施工。实践证明使用效果良好,具有广阔的应用前景。The integral steel sleeve box is characterized by low efficiency and high cost.Considering construction of one hundred more abutments in Xiangjiang river Changsha comprehensive hub lock project,we design a new-type combined prestressed steel sleeve box,which applies the prestressed steel wire to combine the pieces of steel sleeve boxes into integrity.By this way,all operation of steel sleeve boxes are transferred from underwater to overwater.At present,120 abutments of various shapes have finished construction,which evidence the good effect and indicate extensive application perspective.
