[0002] In the fields of architecture and civil engineering, especially in foundation and foundation pit support projects, underwater cast-in-place concrete structures such as bored piles and diaphragm walls are common construction methods. To ensure the stability and bearing capacity of these structures, it is usually necessary to over-pour a certain height of concrete above the design elevation. Traditionally, the over-poured concrete is broken and removed manually or mechanically after final setting.
