Abstract
A method of constructing an underwater concrete block structure includes assembling a plurality of concrete blocks into a concrete block assembly, forming a drilled borehole in the underwater ground under a concrete hole of the concrete block assembly, and forming a concrete column in the concrete hole and the drilled borehole, thereby greatly increasing the stability of the underwater concrete block structure.
Claims10
A method of constructing an underwater concrete block structure, the method comprising:
- fabricating a plurality of concrete blocks each having a vertical hole extending in a vertical direction;
- continuously arranging the plurality of concrete blocks on the underwater ground in a horizontal direction to form a concrete block assembly, whereby the vertical hole of the concrete block is formed into a concrete hole in which an upper end thereof is opened while a lower end thereof is blocked by the underwater ground;
- after the concrete block assembly is formed, drilling the underwater ground under the concrete hole to form a drilled borehole in line with the concrete hole;
- and
- after the drilled borehole is formed, forming a concrete column through the concrete hole and the drilled borehole,
- wherein an upper surface of the concrete block assembly is located above the water surface, so that the drilled borehole is formed in a dry operation by a drilling equipment placed on the upper surface of the concrete block assembly.
