The invention discloses a steel pipe concrete sleeper suitable for ballastless tracks, which comprises two or more sleeper concrete blocks and a sleeper connecting piece for connecting the sleeper concrete blocks, the sleeper concrete block is in a block structure, and is made of concrete It is made by pouring, and there are embedded parts for fixing the rails and steel mesh or stirrups connecting the sleeper connectors; the sleeper connectors are composed of a plurality of hollow steel pipes arranged horizontally between the concrete blocks of the sleeper. During the block pouring process, the hollow steel pipe is filled with concrete at the same time to form the concrete filled steel pipe, and then the sleeper connector and the concrete block of the sleeper are poured into one body. In the invention, the concrete-filled steel tube is applied in the concrete sleeper of ballastless track, the concrete-filled steel tube is used as the connector of the sleeper block, and the concrete-filled steel tube and the concrete block of the sleeper are integrally formed, so as to effectively increase the geometric shape and position retention capacity of the sleeper, reduce the amount of steel, and have the advantages of simple preparation , Strong constructability and so on.
