Slipping a Slope On The Inside Of A Breakwater In Japan


Maeda Road Construction Company in Tokyo, Japan, recently completed a slope project with their four-track Commander III. The project required them to slipform a 9.8 foot (3 m) wide slab at a 1:2.4 slope. Concrete slump was two inches (50 mm).

The project was part of building a slope on the inside of a breakwater. At the top of the slope is a barrier and on the ocean-side are specially made concrete structures designed to dissipate water wave energy coming off the ocean and keep the water from flowing over the barrier.

A structure was built over the Commander III to pivot the mold at the bottom of the slope and to support the mold at the top of the slope.
