Slope landslide prevention method

摘要

PPROBLEM TO BE SOLVED: To provide a slope landslide preventing method according to which an excellent landslide preventive effect is exerted, the degree of improvement of earth can be flexibly set, civil engineering works are hardly limited by execution conditions, only small-scale temporary works are required, and the works are carried out in a short construction period and at a low cost. PSOLUTION: The slope landscape preventing method is implemented on the basis of infilled grout works. Specifically a plurality of boreholes are perpendicularly drilled from a surface of landslide soil lump down to stable ground along a sliding direction of the landslide soil lump at predetermined intervals, and a grouting material is injected into the soil lump via the boreholes, to thereby form a landslide resisting body made up of a consolidation body group having an entire height substantially equal to the length of the borehole. By implementing a similar method, a landslide surface strengthening body is arranged astride the stable ground and the landslide soil lump in a direction crossing the landslide resisting bodies, and therefore more efficient landslide preventive effect is achieved. The grouting material is made of aqueous slurry containing therein cement and water as essential ingredients. PCOPYRIGHT: (C)2006,JPO&NCIPI
