Batter pile vibration isolation barrier for reducing subway operation induced vibration and preparation method thereof
The invention discloses a batter pile vibration isolation barrier for reducing subway operation induced vibration and a preparation method thereof. The batter pile vibration isolation barrier is arranged between a vibration source and a vibration receptor and comprises at least one row of vibration isolation layers, each row of vibration isolation layers is composed of a plurality of vibration isolation piles which are arranged at intervals, and each vibration isolation pile comprises a prestressed concrete hollow pipe pile and a filling material packed in the prestressed concrete hollow pipe pile. The phase difference formed by reflection, refraction and diffraction of vibration waves after the vibration waves encounter the vibration isolation barrier is utilized, so that the propagation energy of the vibration waves is effectively reduced, and the purpose of vibration reduction and isolation is achieved; and according to the barrier structure, the prestressed pipe piles are adopted as the sleeves, the construction difficulty can be effectively reduced, the construction efficiency is improved, meanwhile, the self-recovery characteristic of the prestressed pipe piles after the prestressed pipe piles are subjected to the vibration effect can be brought into full play, the strength of the vibration isolation barrier is improved, and the service life of the vibration isolation barrier is prolonged.
本发明公开了一种减轻地铁运行诱发振动的斜桩隔振屏障及其制备方法，斜桩隔振屏障设置在振源与振动受体之间，包括至少一排隔振层，每排隔振层由多个间隔布置的隔振桩组成，每个隔振桩包括预应力混凝土空心管桩和填充在预应力混凝土空心管桩内的填充材料。本发明利用振动波在遇到隔振屏障后发生反射、折射及衍射形成的相位差，有效减小振动波传播能量，进而达到减隔振目的；该屏障结构采用预应力管桩作为套筒，可有效减小施工难度，提高施工效率，同时还可充分发挥预应力管桩自身在受到振动作用后的自恢复特点，提高隔振屏障的强度，增加隔振屏障的使用年限。
