(57) A method of constructing an underwater concrete block structure (200) includes assembling a plurality of concrete blocks (10) into a concrete block assembly (100), forming a drilled borehole (102) in the underwater ground (20) under a concrete hole (101) of the concrete block assembly (100), and forming a concrete column (110) in the concrete hole (101) and the drilled borehole (102), thereby greatly increasing the stability of the underwater concrete block structure (200). An underwater concrete block structure is obtained using the method.
