PURPOSE:To raise the working efficiency of retaining wall construction by a method in which support frames are set in parallel on the bottom slab of concrete, iron bars are set between the slope and the support frames, and concrete is placed into the space covered with a net laid on the outside of the support frames. CONSTITUTION:A support frame 1 is made up of two pillars 11 with claws 13 and plural supporters 12 in such a way as to form it into a ladder shape. Plural support frames 1 are set on leveling concrete 6, iron bars 2 are set between the slope 5 and the support frames 1, and then concrete 4 is placed to form a bottom slab A. On the hardened bottom slab A, the support frames 1 are set in parallel with a spacing from the slope 5 by turning the claws 13 outwardly, and iron bars 2 and a spacer 8 are set between the support frames 1 and the slope 5 and a net 3 is laid on the claws 13. Concrete 4 is then placed into the space between the net 3 and the slope 5 to form a retaining wall B. Air bubbles and water can escape through the net mesh and good-quality concrete retaining wall can thus be constructed. |
