Ultralow-frequency vibration isolation multi-layer filling pile foundation
The invention relates to an ultralow-frequency vibration isolation multi-layer filling pile foundation. The ultralow-frequency vibration isolation multi-layer filling pile foundation comprises a pile core, a soft body layer, a pipe pile, a grouting layer and a bottom sealing block, wherein the pipe pile is formed by sequentially connecting a plurality of prefabricated cylinders with through holes formed along the axis; the pile core is formed by stacking a plurality of reinforced concrete prefabricated cylinders; the soft body layer is clamped between the pipe pile and the pile core; the grouting layer is distributed on the periphery of the pipe pile; and the bottom sealing block is arranged in the pipe pile and located at the bottom of the pipe pile. The multi-layer filling pile foundation is periodically arranged, and ultralow-frequency vibration waves with the specific frequency can be isolated.
本发明涉及一种超低频隔振多层填充桩基，包括桩芯、软体层、管桩、注浆层以及封底块；管桩由多个沿轴线开设通孔的预制圆柱体依次连接而成；桩芯由钢筋混凝土预制多个圆柱体叠加形成；软体层夹设于管桩和桩芯之间；注浆层分布于管桩外围；封底块设置于管桩中，且位于管桩的底部。将该多层填充桩基周期布置，可隔断特定频率的超低频振动波。
