一种地铁盾构隧道降坡轨枕
摘要：
本实用新型涉及一种地铁盾构隧道降坡轨枕，其包括枕木(1)、增高装置(2)和压轨器(3)；所述枕木(1)底部与管片相接；所述增高装置(2)的下部与所述枕木(1)相接，上部设置用于固定道轨的压轨器(3)；所述增高装置(2)的高度根据其所在隧道位置处的隧道坡度来选择。本实用新型结构简单，设计合理，使用方便，且使用过程稳定可靠，能够通过灵活可变的增高装置来改变轨道的坡度，使轨道坡度由陡变缓，增加隧道运输车辆行驶的安全性。
摘要（英）：

The utility model relates to a downhill sleeper for a subway shield tunnel. The downhill sleeper comprises a sleeper (1), a heightening device (2) and a rail pressing device (3), the bottom of the sleeper (1) is connected with a segment; the lower part of the heightening device (2) is connected with the sleeper (1), and the upper part of the heightening device (2) is provided with a rail pressingdevice (3) for fixing a rail; the height of the heightening device (2) is selected according to the gradient of the tunnel where the heightening device is located. The tunnel transport vehicle heightening device is simple in structure, reasonable in design, convenient to use, stable and reliable in use process, and capable of changing the gradient of a track through the flexibly-variable heightening device, enabling the gradient of the track to be changed from steep to slow and improving the running safety of the tunnel transport vehicle.
