A tieback alignment and access device has a hollow core and vertically aligned angled anchor subassemblies that provide attachment points for tieback anchors that pass laterally through the hollow core. The hollow core is configured to allow a cutting tool (e.g., a drill bit) to be inserted therein longitudinally and used to cut the tieback anchors at any time. When cast into a contiguous temporary support-of-excavation wall, the angled anchor subassemblies are set back from an outwardly facing surface of the wall resulting in a smooth surface.

Description of the Related Art
FIG. 1 is a perspective view of an embodiment of a tieback anchor alignment and access device.
FIG. 2 is an exploded perspective view of the tieback anchor alignment and access device of FIG. 1.
FIG. 3A is a top (plan) view of the tieback anchor alignment and access device of FIG. 1 installed in a contiguous temporary SOE wall omitting rebar for clarity.
FIG. 4A illustrates a tieback anchor alignment and access device 10 embedded in a contiguous temporary SOE wall 12 that is supporting soil 14. The device 10 is anchored to the soil by at least one tieback anchor 20. Rebar (not shown), which would typically be included in the SOE wall 12, has been omitted from FIGS. 3A-4B.
As is apparent to those of ordinary skill in the art, any number of laterally spaced apart devices each like the device 10 may be embedded in the SOE wall 12. For example, referring to FIGS. 3B and 5B, a plurality of devices 10A-10C each substantially identical to the device 10 (see FIG. 1) may be embedded within the SOE wall 12. Further, each of the devices 10A-10C is attached to one or more tieback anchors 20 that anchor the devices 10A-10C (and the SOE wall 12 in which the devices 10A-10C are embedded) to the soil 14 (see FIG. 3B). As is apparent to those of ordinary skill in the art, any number of tieback anchors may be attached to each of the device 10A-10C and used to anchor the SOE wall 12 to the soil 14 (see FIG. 3B).
Referring to FIG. 4A, the device 10 includes a different anchor subassembly 30 attached to an upright support assembly 32 for each tieback anchor 20 attached the device 10. Referring to FIGS. 1-3A and 4A-5A, for ease of illustration, the device 10 has been illustrated as including only the single anchor subassembly 30 for attachment to the single tieback anchor 20 (see FIGS. 3A and 4A-5A). However, any number of subassemblies each like the subassembly 30 may be attached to the upright support assembly 32 and coupled to a different tieback anchor 20. For example, referring to FIG. 5B, the device 10A, which is attached to three different tieback anchors 20, includes three subassemblies 30A-30C. Similarly, the device 10B, which is attached to three different tieback anchors 20, includes three subassemblies 30D-30F, and the device 10C, which is also attached to three different tieback anchors 20, includes three subassemblies 30G-30I. The subassemblies 30A-30I are substantially identical to one another and, as shown in FIG. 5B, are each coupled to a different tieback anchor 20.
