CONSTRUCTING METHOD FOR RETAINING WALL USING ARTIFICIAL LIGHTWEIGHT SOIL

PURPOSE:To prevent differential settlement and landslide from being generated and enable work to be executed with machines and shorten the term of construction by placing lightweight soil mixture between the face of slope and a mold, and by repeating the placing on the upper section gradually in the same manner after solidifying, to construct a retaining wall. CONSTITUTION:On the lower ground surface E of ready-set filling 1, a concrete-tile- shaped form 2 with an anchor section 2b fitted on the rear side surface is constructed steeper than the face W1 of slope. After that, the lightweight soil mixture A of earth B, aqueous solution C with foaming agent dissolved in water, bubble D for foaming the foaming agent with compressed air, and concreting agent E which are mixed with each other, is placed between the form 2 and the face W2 of slope, up to the level of the form 2. Besides, after the mixture A is concreted, the following step form 2 is set on the lower step form 2, and the form is repeatedly placed gradually, and a retaining wall 3 is constructed. As a result, the load of ground pressure or the like is not applied to the form 2, and ground settlement is prevented from being generated, and the weight of the mixture A is light, and so a grade can be set to be steep, and upper and lower land areas to be used can be widened.
