Provided is an assembled steel pipe concrete bi-block railway sleeper, comprising a first concrete railway sleeper block (1), a second concrete railway sleeper block (2) and a plurality of matched steel pipe concrete columns (3), wherein the above are all processed independently. These components stay separate in a transportation link and a warehousing link, and after being conveyed to a construction site together, the steel pipe concrete columns (3) and two concrete railway sleeper blocks are assembled into a whole by means of threads or bonding slurry. Not only can the processes of fixing and assembling be realized rapidly with high precision at the construction site, but it can also be ensured that the railway sleeper is provided with a good form and position maintaining ability, while significantly reducing the use of the connecting members. In particular, the railway sleeper has the outstanding advantages of reducing the processing difficulty of the plurality of links, such as in manufacturing, warehousing, transportation and construction, improving the process efficiency and lowering costs.
