REINFORCED SOIL PIER AND THE BRIDGE CONSTRUCTION METHOD THEREWITH

摘要

A reinforced soil pier and a bridge construction method using the same are provided to secure constructability and economical efficiency by manufacturing and constructing a pier quickly using a soil body with reinforced tensile resistance against applied load. A reinforced soil pier includes a column body(100) filled with soils(120) prestressed axially to increase tensile resistance by load in a circular pipe(110), and a foundation(200) formed on the lower part of the column body to support the column body. A bridge construction method using a reinforced soil pier comprises the steps of: leveling the ground where a reinforced soil pier is to be constructed and performing pit excavation; forming a foundation by placing concrete in a form for a foundation; installing a circular pipe on the foundation to make the bottom of a circular pipe set to the upper part of the foundation to the appointed height to set a tension member upward; filling up the inside of the circular pipe with soils including sand; installing an upper support plate(140), and forming anchor holes and installing anchorages(141,142) on the upper support plate to make the other end of the upward extended tension member tensed and anchored; installing girders between a pier and an abutment; and installing a bridge slab on the upper side of the girders.
