CAST-IN-PLACE DIAMETER ENLARGED PILE AND CONSTRUCTION METHOD FOR THE SAME
To provide a cast-in-place diameter enlarged pile and construction method for the same that have large support force using the diameter enlarged section and that can resist large sectional stress caused on the shaft section.SOLUTION: The cast-in-place diameter enlarged pile has a diameter enlarged section 7. The diameter enlarged section 7 is provided with a switching complete height H that is a concrete strength boundary. The upper concrete above the switching complete height H has higher strength than that of the lower concrete.SELECTED DRAWING: Figure 6
【課題】拡径部で大きな支持力を担いつつ、軸部に発生する大きな断面応力に対抗できる場所打ち拡径杭とその構築方法を提供する。【解決手段】拡径部７を有する場所打ち拡径杭であって、拡径部７にコンクリートの強度境界である切替完了高さＨが設けられており、切替完了高さＨより上方側の上部コンクリートを下方側の下部コンクリートより高強度としたことを特徴とする。【選択図】図６
