PURPOSE:To simplify construction and to build a retaining wall being excellent indraining ability, by a method wherein a retaining wall is formed,a nd afer a water permeable sheet is horizontally laid on the back of the retaining wall, soil is rolling-compacted on the sheet to orderly build banking layers between which the water permeable sheet is located. CONSTITUTION:Strut 2 are pressed in a ground, and a retaining wall panel 3 is engaged between the struts 2 to build a retaining wall A. The one end of the water permeable sheet 1 is folded back arond a locking rod 4 to secure the one end by heat fusion and bolt locking, and the one end of the sheet 1 is secured to the retaining wall A. Soil is conveyed to the back of the retaining wall A and is spread on the water permeably sheet 1 for rolling compaction to build a banking layer G1, and following banking layers are built in a similar manner as described above. This reduces an earth pressure exerted on the retaining wall, markedly improves safety of the retaining wall through prevention of fall-down of the same, enables rapid drainage of water, and enables prevention of production of an exessive gap water pressure in a banking. |
