53951859, Mar 7, 1995

Filed:

Nov 22, 1993

Appl. No.:

8/155231

Inventors:

Harry Schnabel - Bethesda MD

Assignee:

Schnabel Foundation Company - Sterling VA

International Classification:

E02D 2900

US Classification:

405287

Abstract:

A method of temporarily shoring and permanently facing an excavated slope or embankment is provided. First, a slope is excavated in successive sections from the top down to form exposed slope faces. A temporary shoring wall is then formed by shoring up the exposed slope face of each successively excavated section with soil nails and at least one layer of pneumatically applied concrete. As the desired final depth of the excavation is reached, the tiebacks are installed. The pneumatically applied concrete is thickened in the area of the tiebacks so as to form reinforcement elements along the exposed slope faces. The reinforcement elements include reinforced steel bars which extend outwardly away from the exposed slope faces. The tie backs are tested, prestressed and secured against the reinforcement elements. Finally, a final retaining wall is formed by pouring and curing a layer of reinforced concrete over the temporary shoring wall and the secured tiebacks.

Abstract:

A method of reinforcing or strengthening an existing earth supporting wall located between a body of water and land is disclosed, wherein the level of the earthen floor adjacent the wall is to be deepened or a portion of the wall has deteriorated. The wall has a first side facing a body of water, an opposite second side in contact with ground and a lower toe portion embedded in the earthen floor beneath the body of water. The method comprises the steps of: installing at least one tieback through the wall in an area adjacent the original level of the earthen floor or adjacent the deteriorated area to provide a stabilizing force to the wall.
