ABSTRACT:
A soil or rock nail retaining wall with an outer face is provided. A method of constructing such a wall is also set forth. A cut is excavated in successive sections to form exposed cut faces. The exposed cut face of each successively excavated section is temporarily supported with a temporary support means comprised of a nail installed through the exposed cut face into the ground. Shotcrete or a layer of barrier material may also be used in forming the temporary support means. Next, an outer face is formed. Facing elements are attached to the nail-supported cut via an isolated reinforced concrete closure. Formwork is used in placing the reinforced concrete closure. The reinforced concrete closure ties together the facing elements and the nail. Finally, free-draining granular backfill material, such as porous concrete, gravel or crushed rock, is placed along the remainder of the retaining wall between the exposed cut face and the facing elements.
