<p>The present invention relates to a construction structure for a semi-reclamation type offshore airfield using a cast-in-place pile of a prefabricated caisson. More specifically, the present invention relates to an independent footing structure for a seafloor using a cast-in-place pile of a prefabricated caisson to provide stability for a lower footing by anchoring a cast-in-place pile to a footing on the seafloor; and to carry out reclamation by unit volume by loading a prefabricated panel on the lower footing as a base in order to integrate the cast-in-place piles fastened to each other, and secure stability of the overall structure. To achieve this, a cast-in-place pile of a prefabricated caisson is applied to an independent footing as a spread footing; concrete is primarily placed on the lower footing on the seafloor; and the concrete is secondarily placed in a plurality of cast-in-place piles on the lower footing by connecting a support pile to a bed rock using RCD equipment through excavation. The prefabricated panel is loaded on a pile reinforcing support in each separated reclamation zone to be filled with crushed stone, earth, and sand in order to increase the loads.</p> |
