SLOPE REINFORCING METHOD USING HIGH-PERFORMANCE SHOTCRETE

摘要

The present invention relates to an assembly-type slope reinforcing method using a high-performance shotcrete and a reinforcing member, the method, after producing, at a batch plant, and transporting normal concrete having a compressive strength of 21-30 MPa to a construction site: forms normal-strength shotcrete by mixing either fly ash or slag fine powder or low-grade mixed material in which fly ash or slag fine powder is mixed, in an increased fluidity state by mixing 20-40% of bubbles of the total volume; forms high-performance shotcrete by mixing either silica fumes or metakaolin or high-grade mixed material in which either silica fumes or metakaolin are mixed; and forms color shotcrete by mixing a coloring material such as an iron oxide or carbon black, so as to sequentially construct an inner layer section, an outer layer section, and a surface layer section on the slope, thereby reducing construction costs and obtaining high strength and high durability so as to facilitate maintenance.
