一、前言水下抛石基床的整平,是重力式水工建筑物施工的一道基本工序。解放三十年来,我国一直沿用人工水下作业的施工方法,不但潜水员劳动强度大,而且效率也低。随着港口事业的发展,船舶日趋大型化,深水建筑物与日俱增,人工整平已远远不能适应形势发展的需要。

With the development of port business, ships are increasingly large-scale, deep-water buildings are increasing day by day, and artificial leveling can not meet the needs of the development of the situation.
