A pre-buried casing tube uses glass fiber reinforced resin as the raw material to enhance the operation strength of the pre-buried casing tube, extend the service life of the pre-buried casing tube, and reduce maintenance cost of the railway transport system. The pre-buried casing tube includes at least one casing tube body, each casing tube body including at least one retaining element, the retaining elements provided in intervals along one side of the casing tube, each casing tube body disposed adjacently so as to form a passage for a screw, each retaining element provided in the passage for the screw.
