Pier revolution apparatus and T-type pier construction method using the same

摘要

PURPOSE: A pier revolving device is provided to gain flexibility and ductility and construct a structurally stabilized T-type pier by installing temporary timbering in line with traffic flow and rotating upper column to the direction. CONSTITUTION: The pier revolving device comprises the following devices as an upper revolving device(10) that is circular closure shape on the whole, which upper plate hole(13) of constant diameter continues to lower center part of the upper plate(11), and extruded at constant thickness, a lower revolving device(20) that is circular plate shape on the whole, digged a rotating disk hole(21) with insertable diameter of the rotating disk in the middle of upper center part to lower plate at constant diameter, sealing materials(30) inserted along contact parts of revolving disk(12) of the upper revolving device(10) and revolving disk holes(21) of the lower revolving devices(20), and plural oil pipes(40) vertically penetrated from lower part of the lower revolving device(20) to revolving disk holes(21).
