RETAINING WALL SYSTEM USING STRUT ASSEMBLY AND EXCAVATING METHOD USING THE SAME

A retaining wall system using a prefabricated strut assembly and an excavation method using the system are provided to carry out excavation continuously and rapidly as the struts bear the soil pressure while supporting the load of concrete slab. A retaining wall system using a prefabricated strut assembly is as follows. A retaining wall is constructed on the ground boundary face. H-posts(30) are driven into the excavation site bordered by the retaining wall. Excavation for building of ground slab is carried out. A wale is applied to the exposed retaining wall and a bracket(40) is installed on each flange of the H-posts. Double vertical struts(210a,210b) are set up to be supported by the bracket, with each post interposed. Double horizontal outside struts(220a,220b) are set up between the double vertical struts. Double horizontal inside struts(230a,230b) are set up between the double vertical struts. A ground slab is constructed. Excavation for building of underground slab is carried out. Construction of underground slab is repeated until the designed basement.
