摘要
PURPOSE: A construction method of an underground structure for preventing concrete of an underground slab and a girder from being cracked is provided to prevent concrete from being cracked by forming a mechanism capable of freely dealing with expansion and shrink. CONSTITUTION: A construction method of an underground structure for preventing concrete of an underground slab and a girder from being cracked is as follows. A retaining wall is built by hammering an H-pile(2). A shear connector is welded in the top end of the H-pile. A first floor slab(6), which comprises a cap beam(6a), is built. A part of the shear connector is buried in the cap beam. A wall girder and a slab are hung on the bottom end of the shear connector. Spacers(12) are installed in contact parts of the retaining wall and the wall girder. The construction is repeated up to a desired underground slab.
