UNDERGROUND CAVITY FILLING METHOD
To provide an underground cavity filling method that reduces the amount of water glass used, in particular, determines a filling area and provides filling within a limited range at a low cost by following different construction steps from the conventional cavity filling method.SOLUTION: The present invention relates to a filling method in which the underground cavities are filled within a predetermined region. In an underground cavity filling method, a plurality of injection holes are drilled along a boundary line between a filled region and a non-filled region, a gelatinous end filler having a lower fluidity than that of a filling filler is injected from the injection hole to form a partition wall surrounding the filled region, and the filled region surrounded by the partition wall is filled with the filling filler having a higher fluidity than that of the end filler. The underground cavity filling method is characterized by preparing a gelatinous second end filler that is less expensive and have a higher fluidity than those of the end filler, and filling the end filler after injecting the second end filler from the plurality of injection holes.SELECTED DRAWING: Figure 1
【課題】本発明は、従来の空洞充填工法と異なる施工ステップを踏むことで、特に水ガラスの使用量を減じ、充填領域が決められ、限定された範囲での充填を低コストで提供できる地下空洞充填工法を提供することを目的とする。【解決手段】本発明は、地中空洞を、決められた領域内に限定して充填する充填工法であり、充填領域と非充填領域との境界線に沿って複数の注入孔を穿設し、該注入孔から中詰充填材より流動性の低いゲル状の端部充填材を注入して、充填領域を囲む隔壁を形成し、前記隔壁で囲まれた充填領域内に前記端部充填材よりも流動性の高い中詰充填材で充填する地下空洞充填工法であって、前記端部充填材よりコストが安価で流動性の高いゲル状の第２端部充填材を用意し、前記第２端部充填材を複数の注入孔から充填した後に端部充填材を充填したことを特徴とする。【選択図】 図1
