Abstract (en)

[origin: US2012076594A1] In a reinforced self-standing earth retaining structure using an arching effect, a soldier pile integrally formed with a soldier pile insertion portion in a vertical direction in a flange at one end of the soldier pile in which a lagging is inserted is installed at a width B to be perpendicular to the ground. A sheet panel protruding portion is inserted in and connected to the soldier pile insertion portion. A sheet panel protruding portion is serially inserted in a sheet panel insertion portion. A compression support plate protruding portion is inserted in and coupled to the sheet panel insertion portion. A relationship between a length L of a group of serial sheet panels and the width B between two groups of serial sheet panels is 0.5≰L/B≰3.0 in a range of an internal friction angle of earth φ=10˜34° and a range of an adhesive power C=0.0˜5.0 ton/m2 so that a back earth pressure is not applied to the front lagging due to the arching effect.
