TUNNEL STRUCTURE USING JOINT STRUCTURE FOR CORRUGATED STEEL PLATE AND CONSTRUCTION METHOD THEREOF

摘要

The present invention is to obtain an efficient reinforcing structure with excellent resistance to earth pressure, by suggesting a corrugated steel plate joint structure (A) including: an external corrugated steel plate (110) installed to form a corrugated cross section; an internal corrugated steel plate (120) which is combined to the inside of the external corrugated steel plate (110) to form a corrugated cross section, and is formed longer than the external corrugated steel plate (110); a protruding part (130) which is formed on an area between a lower part of the external corrugated steel plate (110) and a lower part of the internal corrugated steel plate (120); a protruding wall (210) which is formed with a concrete material buried with a reinforcing bar assembly (201) inside, and also is formed on a lower area of the external corrugated steel plate (110) and an outside area of the protruding part (130); a wall (200) comprising a main wall (220) formed on a lower part of the protruding wall (210) and a lower part of the internal corrugated steel plate (120); and an anchor (300) which has one end buried in the wall (200) by being combined to the reinforcing bar (201), and has another end combined to the internal corrugated steel plate (120) by being exposed from the wall (200).
