Variable filler for supporting column-type wall

TL;DR: In this paper, a variable filler is used to support a column-type soil retaining wall, which is installed between a soil wall and a deck plate constructed on a ground excavation surface of various kinds of civil and architectural construction sites.

Abstract: The present invention relates to a variable filler to support a column-type soil retaining wall, which is installed between a soil retaining wall and a deck plate constructed on a ground excavation surface of various kinds of civil and architectural construction sites. In particular, the variable filler requires a space required for arranging a rebar and deposit concrete during bottom-up construction for an underground soil retaining wall space, placed between a structure slab and a retaining wall (temporary wall) before a vertical member, which is the weakest portion in a method to construct an underground structure in a top-down type, by the bottom-up construction is completed and, at the same time, plays a role of transferring soil pressure of the soil retaining wall to the slab structure. Accordingly, the variable filler is easily installed, thereby providing construction convenience, improving supporting force, and being easily installed regardless of an interval between the soil retaining wall and the deck plate, which is uneven in a site or among sites.
