International Classification:

E02D 520

Abstract:

A tieback retaining wall structure and a method for constructing the same having improved corrosion protection for tieback connecting devices connecting tiebacks to soldier beams, and panel connecting devices connecting precast concrete panels to soldier beams is disclosed. The structure also provides an improved and simpler method of drainage behind a wall. After soldier beams are placed in the earthen mass to be retained, excavation is completed, tiebacks are installed and fastened, and any necessary temporary earth retaining devices are in place, elongated inflatable bags are positioned between the excavation and the precast concrete panels. Then the concrete panels are attached to the soldier beams. The bags preferably are inflated with a cementitious material which forms a sealed first channel surrounding the tieback connecting devices and the panel connecting devices, and a second channel between adjacent beams. The first channel is filled with a cementitious material.

Abstract:

A retaining wall system is comprised of a retaining wall with an outer face. A cut is excavated in successive sections to form exposed cut faces. The exposed cut face of each successively excavated section may be temporarily supported with pneumatically applied concrete. A concrete wale is then formed horizontally along a portion of the exposed cut face of each successively excavated section. Next, tiebacks are installed through the concrete wale. The tiebacks are tested, tensioned and secured against the concrete wale. After the excavation has been completed and the retaining wall formed, an outer face is provided which extends to the full height of the retaining wall. A concrete footing is first provided at the base of the retaining wall. Next, a first tier of facing elements is erected above the concrete footing. These facing elements are then secured to a first adjacent concrete wale at a first connection point.
