PROBLEM TO BE SOLVED: To provide a method for constructing a structure reducing a generated industrial-waste junk, preventing the deformation of a reinforcement, the generation of noises and dust and workmen's accident, shortening the term of works and being capable of bonding a diaphragm wall and a member installed to the diaphragm wall by using the reinforcement under a sound state in the case of a wall-head chipping and a structure. SOLUTION: An excavating ditch 3 is excavated to a ground, a cage 5 in which a wall-head cap 7 is installed at an upper end, is inserted, and concrete is placed, thus forming the diaphragm wall. The wall-head cap 7c protecting a main reinforcement 11c excepting a lap joint section 39 is mounted on the cage 5c with the lap joint section 39, and the wall-head cap 7d protecting the main reinforcement 11d excepting the lap joint section 39 is fitted in the cage 5d. The diaphragm wall is formed, and the wall-head cap 7 is removed and a section in the vicinity of the upper end of the main reinforcement 11 is exposed. Concrete positioned in the cavity 30 or the like of the wall-head cap 7 is removed, and the diaphragm wall, a footing in an upper section and the structure such as a top slab or the like are connected through the exposed main reinforcement 11.
