High-tensile-strength composite sleeper, material preparation scheme and forming method of high-tensile-strength composite sleeper
The invention relates to the technical field of railway engineering construction, in particular to a high-tensile-strength composite sleeper, a material preparation scheme and a forming method of the high-tensile-strength composite sleeper. The high-tensile-strength composite sleeper comprises a sleeper body, a sleeper core and spike mounting seats. A foaming cavity is formed in the pillow body. The pillow inner is a foaming body and is formed in the foaming cavity. And after the foaming process is finished, the spike mounting seat is surrounded by the cured pillow core. The spike mounting seat is formed by combining a top plate, a bottom plate and a connecting transition piece. And a threaded mounting hole for screwing in a threaded spike is formed in the spike mounting seat. Therefore, on one hand, when the steel rail is loaded, drawing force is transmitted to the spike mounting seats through the threaded spikes, and due to the fact that the spike mounting seats are always subjected to the effect of stable wrapping force from the pillow inner, the drawing force can be effectively balanced; and on the other hand, the foamed and cold-cured sleeper inner can be reserved in the foaming cavity, and the sleeper inner does not need to be taken out and cleaned subsequently, so that the manufacturing period of the composite sleeper is obviously shortened.
本发明涉及铁路工程施工技术领域，尤其是一种高抗拉强度复合轨枕、材料制配方案及其成型方法。其中，高抗拉强度复合轨枕包括枕体、枕芯以及道钉安装座。枕体内设有发泡腔。枕芯为发泡体，其成型于发泡腔中。待发泡工序完毕，道钉安装座被固化态的枕芯所包围。道钉安装座由顶板、底板以及连接过渡件组合而成。在道钉安装座上成型出有供螺纹道钉旋入的螺纹安装孔。如此，一方面，当钢轨负载时，拉拔力经由螺纹道钉而传递至道钉安装座，因道钉安装座始终受到来自于枕芯的稳性裹持力的作用，可有效对拉拔力进行平衡；另一方面，发泡、冷固后枕芯可留存于发泡腔中，后续无须对其执行掏出、清理操作，从而使得复合轨枕的制造周期得以明显缩短。
