PROBLEM TO BE SOLVED: To provide a composite foundation pile which is suitable for a foundation pile of a small-scale building such as a house, which has particularly great bearing capacity and a drainage function during liquefaction, and which can be inexpensively constructed.SOLUTION: A composite foundation pile 1 is constructed within ground that comprises an upper layer 2 where consolidation settlement is a concern, and a lower layer 5 where there is little possibility of great settlement over a long period of time. The composite foundation pile comprises a crushed stone pile 3 that is constructed within the upper layer 2 in such a manner as to continue into the lower layer 5, a prefabricated pile 4 that is constructed within the crushed stone pile 3 in such a manner as to continue into the lower layer 5, and a foot protection part 6 that is constructed within the lower layer 5 immediately below the prefabricated pile 4 and the crushed stone pile 3. The foot protection part 6 is constructed from crushed stone or gravel.SELECTED DRAWING: Figure 1
【課題】住宅等の小規模建物の基礎杭に適し、特に高い支持力と液状化時の排水機能を備有し、かつ低コスト施工の可能な合成基礎杭を提供する。【解決手段】圧密沈下が懸念される上部層２と長期にわたって大きな沈下のおそれの少ない下部層５とからなる地盤内に施工される合成基礎杭１において、上部層２内に下部層５まで連続して施工された砕石杭３と、砕石杭３内に下部層５まで連続して施工された既製杭４と、既製杭４および砕石杭３直下の下部層５内に施工された根固め部６とから構成する。根固め部６は砕石または砂利から施工する。【選択図】図１
