Vibro-replacement stone column and construction method thereof
The invention relates to the technical field of stone columns, in particular to a vibro-replacement stone column. The vibro-replacement stone column comprises a structure foundation, and the structurefoundation is formed by arranging a plurality of stone columns in a rectangular array mode. According to the vibro-replacement stone column, during hole forming and column forming, a vibrohammer violently vibrates, filling materials and foundation soil are compacted and violently pre-vibrated at the same time, the anti-liquefaction capability of the foundation is favorably enhanced, a composite soil layer plays a role of a cushion layer, and the cushion layer diffuses loads to enable stress distribution to tend to be uniform, so that the overall bearing capacity of the foundation is improved,and the settlement amount is reduced.
本发明涉及碎石桩技术领域，具体是一种振冲碎石桩，包括构筑物地基；所述构筑物地基由若干碎石桩按矩形阵列布设而成。本发明在碎石桩在成孔及成桩时，振动锤的强烈振动，使填入料和地基土在挤密的同时获得强烈的预震，对地基增强抗液化能力是极为有利的。复合土层起垫层作用，垫层将荷载扩散使应力分布趋于均匀，从而提高地基整体的承载力，减少沉降量。
