PURPOSE: An underground structure driving apparatus and a construction method are provided to reduce costs and a construction period because an installation of horizontal structures for each floor and a balance control are easy and to easily maintain a vertical condition between the horizontal structure for each floor and temporary installation member. CONSTITUTION: An underground structure driving apparatus comprises a retaining wall(10), a plurality of center piles(20), a horizontal structure of a first floor(30), a temporary connection member, a horizontal structure of each floor, and a bracket(21). The retaining wall is formed by being pressured along the circumference of an excavated area. The center pile is penetrated into the excavated area to be removable. The horizontal structure of the first floor is installed in the upper part of the center pile and supports to stand earth pressure of the retaining wall. The temporary connection member is fixed to the horizontal structure of the first floor and extended to the downward direction and composed to be possible to adjust a length. The horizontal structure for each floor is supported to the end part of the temporary connection member. The bracket is mounted in the center pile to support the horizontal structure for each floor connected to the other side of the temporary connection member. |
