FILLING MATERIAL
To provide a filling material capable of completely filling a duct line with sand or the like without pump force feed with using flowability to move coarse particle material and coarse aggregate long distance.SOLUTION: A constituting material consists of a separation resistant material, a coarse particle material, water and a fine air bubble, in which the added water is 1.9 to 19.0 wt.% based on weight of the separation resistant material, specific gravity containing air after milling and mixing is 0.7 to 2.1, material is not separated in water, having self leveling property for enlarging a filling area by flowing in a cavity by self weight without relaying on pressure, and exhibiting water permeability with water permeability coefficient of 1.0×10cm/sec after filling. Further a separation promoter is preferably added after supplying to a cavity to be filled (for example a subsurface drain pipe).SELECTED DRAWING: Figure 1
【課題】粗粒材・粗骨材を長距離移動させる流動性を利用してポンプ圧送なしでも管路内を砂等で完全に充填することが出来る充填材の提供。【解決手段】構成する材料が、不分離性材料と粗粒材と水と微細な空気泡からなり、前記の添加する水は前記不分離性材料の重量に対し１．９〜１９．０重量％であり、練り混ぜ後の空気を含む比重は０．７〜２．１であり、水中で材料分離せず、圧力によらず自重で空洞内を流動して充填領域を拡大するセルフレベリング性を有し、充填後は透水係数１．０×１０−４ｃｍ／ｓｅｃ以上の透水性を示すことを特徴とする充填材。さらに、充填するべき空洞（例えば、地下排水管）に供給した後、分離促進剤が添加されるのが好ましい。【選択図】図１
