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.
