Discrete doll-shaped periodic vibration reduction and isolation row pile and arrangement method thereof
The invention discloses a discrete doll-shaped periodic vibration reduction and isolation row pile and an arrangement method thereof. The discrete doll-shaped periodic vibration reduction and isolation row pile comprises a plurality of discrete doll-shaped vibration reduction and isolation single piles arranged according to square lattices; each single pile structure comprises a local resonance concrete layer, a rubber soft body layer and a steel pipe wrapping layer which are sequentially nested in a multi-layer mode. The single piles are of a sleeve doll-shaped structure on the whole, the cross section of each single pile is round, and the rubber soft body layer is arranged to be in a discrete type in the circumferential direction. According to the row pile, the band gap characteristic of a periodic structure is utilized, environment vibration with the frequency within the attenuation domain range is restrained, and therefore adverse effects caused by rail transit operation, earthquakes and other environment vibration are reduced; the limitation that a traditional periodic vibration reduction and isolation row pile is not beneficial to isolation of low-frequency vibration waves in a limited site can be broken through; the defect that a traditional periodic vibration reduction and isolation row pile can only isolate single-frequency-band vibration can be overcome, and multi-frequency-band vibration reduction and isolation application is achieved; high geometric variability is achieved, and environment vibration of different frequency bands can be attenuated in a targeted mode; durability is good, and operability is high.
本发明公开了一种离散套娃型周期减隔振排桩及其布设方法，包括：多根按照正方形晶格布设的离散套娃型减隔振单桩；每根单桩结构包括依次多层嵌套的局域共振混凝土层、橡胶软体层和钢管包裹层；所述单桩整体上呈现套娃型构造，且每根单桩的横截面形式为圆形，橡胶软体层沿环向设置成离散型。该排桩利用周期结构的带隙特性，抑制频率处于衰减域范围内的环境振动，以减小轨道交通运行、地震等环境振动带来的不利影响；能够打破传统周期减隔振排桩不利于在有限场地隔离低频振动波的限制；能够弥补传统周期减隔振排桩只能隔离单一频段振动的缺陷，实现多频段减隔振应用；具有较强几何多变性，可针对性衰减不同频段的环境振动；耐久性好、可操作性高。
