Multi-layer composite type vibration reduction track structure for urban rail transit engineering and construction method of multi-layer composite type vibration reduction track structure
The invention provides a multi-layer composite vibration reduction track structure for urban rail transit engineering and a construction method, the track structure is composed of a steel rail, a buckling part, a track plate, an elastic vibration reduction cushion layer, a self-leveling mortar pouring bag layer, a base layer, a limiting structure and the like, and the buckling part adopts a tuning type vibration reduction fastener; the track plate is an assembly type prestressed concrete frame plate, the elastic damping cushion layer is pasted below the track plate in a strip mode, the self-leveling high-elasticity mortar is poured through a mortar bag, and the base layer is filled with reinforced concrete. The rail structure is formed by compositing the vibration reduction fasteners and the multiple layers of vibration reduction materials, compared with an original single vibration reduction measure and a vibration reduction adjusting layer, the vibration reduction and noise reduction effect is better, the structural safety is high, the manufacturing cost is economical and reasonable, the line precision is high, construction is rapid, operation and maintenance are convenient, and good application and popularization value is achieved in the field of vibration reduction and noise reduction of urban rail transit engineering.
本发明提供了一种城市轨道交通工程多层复合式减振轨道结构及施工方法，该轨道结构由钢轨、扣配件、轨道板、弹性减振垫层、自流平砂浆灌注袋层、基底层、限位结构等组成，扣配件采用调谐式减振扣件，轨道板采用装配式预应力混凝土框架板，弹性减振垫层带状粘贴于轨道板下，自流平高弹性砂浆采用砂浆袋进行灌注，基底层由钢筋混凝土填充而成。该轨道结构采用减振扣件和多层减振材料复合而成，相较原单一减振措施和减振调整层，减振降噪效果更优，结构安全性高，造价经济合理，线路精度高，且施工快捷，运营维修方便，在城市轨道交通工程减振降噪领域具有较好的推广应用价值。
