Vibration reduction floating structure of subway upper cover building and construction method
The invention provides a vibration reduction floating structure of a subway upper cover building and a construction method.The vibration reduction floating structure comprises a vibration reduction technical bottom plate formed by splicing a plurality of vibration reduction bottom plates through modified asphalt waterproof coiled materials, and first filling plates are horizontally arranged on all the side walls of the vibration reduction technical bottom plate; second filling plates are vertically arranged over the first filling plates, the vibration reduction bottom plate comprises an upper force bearing plate and a lower force bearing plate which are arranged in parallel from top to bottom, and a plurality of triangular structure units parallel to one another are sequentially arranged between the upper force bearing plate and the lower force bearing plate from one end to the other end. Each triangular structure unit comprises two arc-shaped plates which are concave downwards and are arranged back to back, a through hole is formed between the two arc-shaped plates, the through hole is filled with multiple pieces of elastic rubber at intervals, and springs are embedded in the elastic rubber. The vibration reduction floating structure can effectively reduce low-frequency vibration caused by Rayleigh waves transmitted through a soil body when a train runs, and is long in service life, low in replacement frequency and low in use cost.
本发明提供了一种地铁上盖建筑的减振浮筑结构及施工方法，所述减振浮筑结构包括由多个减振底板通过改性沥青防水卷材拼接而成的减振技术底板，减振技术底板各侧壁处均水平设置有第一填充板，第一填充板的正上方均竖直设置有第二填充板，所述减振底板包括自上而下平行设置的上承力板和下承力板，上承力板和下承力板之间自一端向另一端依次设置有多个相互平行的三角结构单元，三角结构单元包括两个下凹且背对设置的弧形板，两个弧形板之间形成有通孔，所述通孔内间隔填充有多个弹力橡胶，所述弹力橡胶内嵌有弹簧。本发明减振浮筑结构能够有效降低列车运行时通过土体传播的Rayleigh波引起的低频振动，且使用寿命长，更换频率低，使用成本低。
