CONSTRUCTION METHOD OF GROUND-MAKING USING ASSEMBLING UNIT OF BASE PILE

摘要

A construction method of a cast-in-place top pile using a top panel assembly is provided to shorten a period of construction and to cut down on the cost of construction by using a top panel assembly composed of plural top piles and reinforcing bars. A construction method of a cast-in-place top pile using a top panel assembly comprises the steps of: assembling plural top piles composed of a support portion(111) having an incline and a pile portion(112) continuously in horizontal and vertical directions and penetrating connecting reinforcing bars(120) to the incline of the support unit of each top pile horizontally and vertically in the cross shape, and then fixing the connecting bar with each top pile(S10); leveling the surface of the soft ground or the ground of cutting and banking sections; installing a PP(polypropylene) mat for civil engineering works on the ground; installing the manufactured top piles continuously on the mat; placing ready mixed concrete in each top pile; hardening the concrete; placing rubble between the top piles and tamping; and placing concrete on the top of the top pile assembly to the appointed thickness, thereby forming a foundation concrete layer.
