Periodic vibration isolation pile for low-frequency vibration waves and construction method
The invention discloses a periodic vibration isolation pile aiming at low-frequency vibration waves and a construction method, a plurality of rows of vibration isolation piles which are periodically arranged are blocked between a vibration source and a building, and each vibration isolation pile comprises a concrete column body, a rubber soft body layer, a steel pile core, a bottom protection layer and a top protection layer. The construction method comprises the following construction steps: S1, determining design parameters according to field vibration frequency, amplitude and field soil layer physical and mechanical parameters; s2, on-site lofting is conducted, and the pile foundation construction position is determined; s3, pile foundation concrete pile body construction is completed according to the cast-in-place pile construction technology; s4, a rubber soft body layer and a steel pile core are constructed; s5, a top concrete protection layer is constructed; and S6, soil around the pile is improved through on-site vibration isolation testing and numerical simulation. The device is simple in structure and convenient to operate, and has an excellent attenuation effect on vibration waves with the frequency lower than 10 Hz. The method is easy to implement, manufacturing is easy, and the problem that the low-frequency vibration wave vibration isolation requirement cannot be met in the prior art is solved.
本发明公开了一种针对低频振动波的周期性隔振桩及施工方法，多排周期性排列的隔振桩阻隔在振源、建筑物之间，隔振桩包括混凝土柱体、橡胶软体层、钢桩芯、底部保护层以及顶部保护层。施工步骤是：S1.根据现场振动频率、幅值及场地土层物理力学参数确定设计参数；S2.现场放样，确定桩基施工位置；S3.根据灌注桩施工工艺完成桩基混凝土桩体施工；S4.进行橡胶软体层及钢桩芯施工；S5.进行顶部混凝土保护层施工；S6.通过现场隔振测试及数值模拟，对桩周土进行改良。结构简单，操作方便，对频率低于10Hz的振动波也有着极好的衰减效果。方法易行，易于制作，解决了现有技术无法满足低频振动波隔振要求的问题。
