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. The second channel is filled with drainage material.
