CRUSHED STONE PILE COMBINE METHOD
To provide a grout injection method and a building foundation construction method which have an antifreezing function utilizing, at a maximum, such a crushed stone pile that an upper part of a crushed stone pile collapses and foundation is inclined upon an earthquake because the upper part of the crushed stone pile is repeatedly frozen and expanded in a cold district.SOLUTION: Quick-drying cement milk is injected to a predetermined depth of a crushed stone pile 1 using natural stone, is mixed in a mixed chamber pipe and is started to be solidified, and then is jetted from a horizontal jet pipe, so that a solidified layer 2 is formed. The cement milk is injected up to a ground upper end from the solidified layer 2, solidified, and is formed into a concrete pipe 3. The solidified layer 2 is formed in a place deeper than a freezing depth part in a cold district and the ground upper end above the solidified layer 2 is formed into the concrete pile 3. Thus, the inclination of the foundation is prevented, and collapse of the upper end of the crushed stone pile 1 is prevented upon an earthquake. A reinforcement 12 for foundation is inserted before the injected cement milk is solidified, and is connected to a reinforcement for general foundation after solidification, so that a building foundation is constructed.SELECTED DRAWING: Figure 21
【課題】寒冷地域では砕石杭の上部が凍結膨張を繰り返す為、地震時等に砕石杭の上部が崩れ基礎が傾く、砕石杭を最大限に活用した、凍結防止機能を有する、グラウト注入工法、建屋基礎工法を提供する。【解決手段】自然石を使用した砕石杭１の所定の深度に速乾性のセメントミルクを注入して、混合室管で混じり合で固化始まり、続いて水平方向噴出管で噴出し固化層２を形成する。固化層２より地上上端部までセメントミルクを注入し固化させてコンクリート杭３に造り変える。寒い冷地域での凍結深度部分より深い所に固化層２を造りその上地上上端部迄コンクリ－ト杭３に造り変える。このようにして基礎の傾きが無くす、地震時に砕石杭１上端部の崩を無くする。注入したセメントミルクが固化する前に基礎用の鉄筋１２を差し込み、固化した後に一般基礎用鉄筋と接続して建屋基礎を造る。【選択図】図２１
