[0002] The massive investment in national infrastructure has brought many construction projects to the construction industry, but the land resources (water area, land area) in some areas are restricted by the poor original topography, unreasonable development, and low effective utilization rate, which has restricted the effective implementation of construction projects. For a long time, the blowing and filling cofferdams such as reclamation and land reclamation have been used. The blowing and filling cofferdam is a common construction method in water conservancy projects.
