METHOD FOR CONSTRUCTING UNDERGROUND RETAINING WALL USING TEMPORARY WALL AS PERMANENT STRUCTURE

摘要

PURPOSE: A constructing method of an underground retaining wall is provided to effectively use limited resources and to reduce construction cost by using a temporary wall as a permanent structure. CONSTITUTION: In finishing an excavation inside a temporary wall, an installation shear connecting device(11) is installed in an H-beam(21) to reinforce the internal force through the integration with a concrete retaining wall before arranging reinforcing bars(3a,4a). Thereby, the temporary wall to be installed temporarily is used as the part of a permanent structure. Therefore, limited resources are used effectively and construction cost is reduced.
