METHOD OF FORMING CONCRETE WALL OF UNDERGROUND STRUCTURE EMPLOYING COMPOSITE SHEET PILE AND COMPOSITE SHEET PILE AS WEIR PANEL

摘要

PURPOSE:To decrease a cost, by a method wherein the one flange of a reinforcing steel material, formed about in an H-shape, is releasably coupled to the one side of a sheet pile body. CONSTITUTION:Soil, produced from excavation of a ground 31, and a hardening agent are agitated for mixing to form a landslide protecting wall front body 21. The one flange 15 of a reinforcing steel material 13 is inserted into a support groove 17, formed by a pair of angles 16 located to the one side of a sheet pile body 11, to form a sheet pile 10. The pile 10 is driven into the landslide protecting front body 21, and the piles 10 are interconnected as the bodies 11 are jointed with each other through a coupling joint 15 of the sheet pile body 11 to form a sheathing wall 22. A weir panel 32 is erected along the sheet pile bodies 11 away from the body 11, and after concrete is placed between the weir plate 32 and the bodies 11 to form a concrete wall, and thereafter the reinforcing steel materials 13 are lifted up for reuse.
