2.5 BREAKWATER - SETTING OUT AND CONSTRUCTION

INVESTIGATION HOW CAN INSTALLATION BE SIMPLIFIED?

How can the construction of the breakwater be streamlined?

CHOOSING AN INSTALLATION METHOD

PREVIOUS LAYOUT

VIBRATION METHOD A vibratory hammer uses vibration to transfer up and down vibratory forces to the pile. The head is not damaged and a high level of efficiency is achieved. This method is also useful for removing piles.

R4 =

450m

R3 = 400m

CREATING SIMPLIFIED RADIUS BREAKWATER In order to simplify the construction of the breakwater they are made up of only four different radius circles and straight arms. By modifying this radius the floating breakwater modules can be prefabricated with only five different sections.

PERCUSSION METHOD A hydraulic or diesel hammer is used to ram the pile down into the ground. In order to avoid weakening or buckling the pile a pile cap is added. This method achieves a high force useful in areas of joint resistance or ground resistance.

R2 = 600m

R1 =

800m

PRESS IN METHOD A hydraulic mechanism grasps the sheet pile driving it downward. The machine is small and does not require a crane. This method is useful in sensitive areas as it is low noise and low vibration. WHY PRESS IN? By utilizing a driving mechanism that is mounted to existing sheetpiles work can continue even when wave action would make cranes and barges dangerous and inoperable. This will also minimize the number of floating vehicles required for the construction of the breakwater keeping the channel clear and reducing pollution.

SIMPLIFIED FLOATING MODULES By maintaining a single radius at each bend of the breakwater each of the 16 floating dock elements at the curve can be fabricated to the same specifications.
