EARTH RETAINING METHOD USING A SELF-SUPPORTED TRUSS STRUCTURE, CAPABLE OF EFFICIENTLY EXCAVATING AND TRANSFERRING SANDS BY FORMING AN EMPTY OPERATING SPACE WITHOUT A STRUT

摘要

PURPOSE: An earth retaining method using a self-supported truss structure is provided to widely use a working space for transferring sands and excavating the ground by omitting a strut used as a horizontal member.;CONSTITUTION: An earth retaining method using a self-supported truss structure is composed like next. An H-pile which is a first vertical member and a raking pile which is a second vertical member are inserted into the underground. A first excavation is performed. A lagging is inserted into the H-pile. A horizontal truss member and diagonal member are installed between the H-pile and raking pile, thereby forming a truss structure. A second excavation is performed. The lagging is inserted into the H-pile. The horizontal truss member and diagonal member are installed between the H-pile and raking pile, thereby forming the truss structure. A third, fourth, fifth excavations are performed. The lagging is inserted into the H-pile. The horizontal truss member and diagonal member are installed between the H-pile and raking pile, thereby finishing the underground excavation.;COPYRIGHT KIPO 2012
