UNDERGROUND CONSTRUCTURE FORM SYSTEM FOR PREVENTING CONCRETES OF UNDERGROUND SLAB AND GIRDER FROM CRACK

摘要

PURPOSE: An underground structure implementation method for preventing the cracks on an underground slab concrete and a girder concrete are provided to prevent the generation of the cracking by making the repetition of expansion and contraction generated by temperature difference free. CONSTITUTION: A basement outer wall(2) for sheathing is constructed on the circumference of a field. A pile(4) including a post and a basis is constructed and the underground excavation construction is performed. A placing part(6) is integrated in the outer surface of a basement outer wall. Slab concrete and girder concrete(8) is set on the settle part of the basement outer wall. An open-cut construction is performed to the bottom of a first floor from a bottom layer.
