PURPOSE:To firmly join together an underground wall and a structure, by a method wherein a shape steel material is previously installed in a reinforcement cage, and after an underground wall is built, the shape steel material is exposed from the underground wall surface, and coupling reinforcement is secured to the other surface of the shape steel material to bury it in concrete of an underground structure. CONSTITUTION:A shape steel material 2, formed in chevron in cross section, is previously secured to reinforcement cage 1 fro a continuous underground wall, truss reinforcements 3 are alternately located along the inner side surface of the chevron shape of the shape steel material 2 for welding. After a recessed part forming material 5, such as foamed styrol, is engaged with the outer surface of the shape steel material 1, the reinforcement cage 1 is inserted into a groove 4 to form an underground continuous wall. Thereafter, soil in the underground continuous wall is excavated to remove the forming material 5 from an exposed wall surface, and coupling reinforcement 8 is located along the outer surface of the chevron of the shape steel material 2 for welding. An underground structure 9, such as columns, beams, are built so as to wrap the coupling reinforcement 8 therein. |
