The invention discloses a subway track ballast layer drainage structure which comprises a track, spikes, a sleeper, a ballast layer, a transmission frame, a drainage structure and a drainage pipe, the spikes are distributed at the left end and the right end of the track, the sleeper vertically fixes the track through the spikes, the ballast layer is arranged on the lower portion of the sleeper, and the transmission frame is installed in the middle of the sleeper. The drainage structure is buried in the middle of the railway ballast layer and corresponds to the middles of the two sleepers, the drainage pipe is installed on the drainage structure, and the left portion of the drainage structure penetrates through the left end of the railway ballast layer. The problems that accumulated water of a railway ballast layer is forced to flow towards the two sides by rail pressure transmitted by a sleeper, flowing emptying of railway ballast is caused in the flowing process, supporting of the sleeper is insufficient due to long-time scouring, and potential safety hazards are generated are solved.
本发明公开了一种地铁轨道道砟层排水结构,包括轨道、道钉、轨枕、道砟层、传动架、排水结构、排水管，所述轨道左右两端分布道钉，所述轨枕通过道钉垂直固定轨道，所述道砟层设置于轨枕下部，所述传动架安装于轨枕中部，所述排水结构埋藏于道砟层中部，且排水结构对应两个轨枕中部，所述排水管安装于排水结构，且排水结构左部穿过过道砟层左端。本发明解决了轨枕传递的轨道压力迫使道砟层的积水向两边流动，流动过程中造成道砟的流动掏空，长时间的冲刷会导致对轨枕的支撑不足，产生安全隐患的问题。
