Abstract

PURPOSE:To obtain blocks suitable for the construction of the foundational ground of reclaimed site by a method in which cubic blocks having a hole at its center and notches at its four corners and molded of a light weight concrete using as coarse aggregate exregate expanded styrol granules and having a specific gravity value. CONSTITUTION:A light weight floating concrete block 1 is manufactured by a method in which expanded styrol granules as coarse aggregate and a light weight fresh concrete of Portland cement, etc., are cast in a form work, and pressed and tamped by a pushing cover mold while applying vibration to it so as to form a concrete block having a specific gravity of 0.7-0.9. The blocks thus obtained are arranged in plane as the first stage on the surface of water, a stopper 7 is driven into a hole by half, a stopper 7 is driven by half into a hole 5 formed by notches 3, and a stopper 7 is driven by half into a hole 6. As the second stage, the light weight concrete blocks 1 are orderly stacked up by piercing the stopper 5 driven into the hole 5 through the hole 2 of the block 1.
