Integrally-formed trapezoidal sleeper damping and buffering composite part and preparation method and application thereof
The invention relates to an integrally-formed trapezoidal sleeper damping and buffering composite part and a preparation method and application thereof, and belongs to the technical field of urban rail transit damping. According to the invention, the nylon wire net is pre-embedded in the high-performance polyurethane anti-vibration pad and the buffer pad in advance, so that the polyurethane anti-vibration pad and the buffer pad compounded with the nylon wire net and the concrete can be cast and molded at one time in the production process of the concrete trapezoidal sleeper prefabricated member to form the integrally molded trapezoidal sleeper vibration-damping and buffering composite prefabricated member; the secondary processing that the anti-vibration pad and the buffering pad are connected with the concrete trapezoidal sleeper prefabricated part through rivets, anchoring or pasting and the like in the construction process is avoided; the concrete trapezoidal sleeper prefabricated part with the polyurethane anti-vibration pad and the buffer pad can be prepared in batches in a factory, and the preparation process is convenient and fast; the polyurethane anti-vibration pad with the silk screen and the buffer pad layer can be continuously produced in a large scale, and the production process is simple and convenient.
本发明涉及一种一体成型梯形轨枕减振缓冲复合件及其制备方法和应用，属于城市轨道交通减振技术领域。本发明中，尼龙丝网提前预埋至高性能聚氨酯减振垫和缓冲垫中，可实现在混凝土梯形轨枕预制件生产过程中，复合有尼龙丝网的聚氨酯减振垫和缓冲垫与混凝土一次性浇注成型制成一体成型梯形轨枕减振缓冲复合件预制件，避免了施工过程减振垫、缓冲垫通过铆钉、锚固或者粘贴等方式的与混凝土梯形轨枕预制件连接的二次加工；带有聚氨酯减振垫和缓冲垫的混凝土梯形轨枕预制件，可在工厂实现批量制备，制备工艺方便快捷；带丝网的聚氨酯减振垫、缓冲垫层可实现连续大批量生产，生产工艺简便。
