Abstract: An earth retention system constructed with a top-down process that can be used for permanent below-grade structures, similar to a “soldier beam and lagging wall,” consists of vertical soldier piles, drainage and waterproofing, and a finished, reinforced concrete facing. The concrete facing is placed pneumatically (i.e., using so-called shotcrete). The system is well-suited to constructing below-grade portions of buildings where excavation lay back is not practical or cost effective and can incorporate permanent lateral support from tieback anchors. The below-grade structure is constructed by excavating down part way, constructing a waterproof “lift” portion of the ultimate structure, excavating down another part way, constructing another waterproof lift portion in a manner to be tied in with the lift portion immediately above, and repeating these steps until the below-grade structure is constructed to the desired depth.

Abstract: An improved mounting structure for the posts of hand rail systems including a mounting arm member positioned within a sleeve monolithically formed within the inner chamber of the post. The sleeve includes a slit that allows for the outflow of water, thereby limiting corrosion and degrading of the post and mounting structure. A series of nubbed projections create grooves within the surface of the sleeve, to secure the mounting arm into the sleeve in a strong manner. A secure fit limits the amount of liquid trapped within the sleeve reducing corrosion. The mounting arm has smaller dimensions, reducing the chances that the arm comes into contact with support rods embedded within the concrete during installation. By avoiding contact with the support rods, concrete spalling is dramatically reduced, adding to the lifetime of the rail system.
