圆形沉箱防波堤港湾的防波堤,通常多采用在抛石基床上安置矩形混凝土沉箱,但此例为在圆形混凝土沉箱的下部设置钢刃,按沉设井筒的要领,使其嵌入海底地基1.5米左右,然后在周围抛石,建成了经济而稳定的防波堤,设置位置的水深,在防波堤堤头段为基准面下13.5米,沉箱的直径为24米,填料为砂土,堤顶高程为+3米。
Circular caissons Breakwater Bay breakwater, usually used in the rubble bed to install rectangular concrete caissons, but in this case the lower part of the circular concrete caissons set steel blade, according to the essentials of sinking the wellbore, making it embedded in the submarine foundations 1.5 meters , And then in the surrounding riprap, built an economic and stable breakwater, set the location of the water depth, in the breakwater embankment section of 13.5 meters below the base level, caisson diameter of 24 meters, the filler for the sand, embankment elevation of + 3 meters.
