The invention provides a rail transit floor, a preparation method and a rail vehicle. The rail transit floor comprises sound insulation layers and at least two layers of base plates, every two adjacent layers of base plates are arranged in an up-down overlapping mode, and at least one sound insulation layer is arranged between every two adjacent layers of base plates. A plurality of first sound absorption holes are formed in the side, close to the sound insulation layer, of the base plate, a plurality of first groove holes are formed in the sound insulation layer, and the first groove holes correspond to the first sound absorption holes one to one. The base plate is adopted as the main body of the floor, so that the flame-retardant and fireproof effects of the floor are ensured. A sound insulation layer is arranged between every two adjacent layers of base plates, and the sound insulation effect of the floor can be improved. A plurality of first sound absorption holes are formed in the side, close to the sound insulation layer, of the base plate, sound attenuation treatment can be conducted through the first sound absorption holes, and the sound insulation effect of the floor is better; the first groove holes and the first sound absorption holes are in one-to-one correspondence and are matched with each other to improve the sound attenuation effect of the rail transit floor.

    本发明提供了一种轨道交通地板及制备方法、轨道车辆。轨道交通地板包括隔音层和至少两层基板,相邻两层所述基板上下叠合设置,且相邻两层所述基板之间设有至少一层所述隔音层;所述基板靠近所述隔音层的一侧开设有多个第一吸音孔,所述隔音层上开设有多个第一槽孔,所述第一槽孔与所述第一吸音孔一一对应。采用基板作为地板的主体,保证地板的阻燃、防火效果。在相邻两层基板之间设有隔音层,可提高地板的隔音效果。基板在靠近隔音层的一侧开设有多个第一吸音孔,利用第一吸音孔可进行消音处理,使地板的隔音效果更佳;第一槽孔和第一吸音孔一一对应,相互配合以提高轨道交通地板的消音效果。
