PURPOSE: A self-supporting retaining wall of steel truss is provided to minimize the external affect including the field condition and prevent an interference with the underground framework. CONSTITUTION: A self-supporting retaining wall of steel truss is as follows. An outside H-pile and an inside H-pile are constructed. A bracket and an inclined reinforcing material are set up after removing soil from an upper inverted-triangle part in the cross section. A bracket and a horizontal strut are set up after removing soil from a lower triangle part in the cross section. A wale connecting the outside H-piles in the section is installed. A horizontal inclined reinforcing material for preventing the buckling of the inside H-Piles is connected. The above steps are repeated till the final excavation height. |
