The invention discloses a pre-embedded sleeve, and a glass fiber reinforced resin matrix is used as a raw material to improve use intensity of the pre-embedded sleeve, so as to achieve effects of prolonging service life of the pre-embedded sleeve and reducing maintenance cost of a rail transit system. The pre-embedded sleeve comprises at least a sleeve body, wherein each sleeve body comprises at least a retaining element, and the retaining elements are arranged at interval along a side surface of the sleeve body. Each sleeve body is arranged in an adjoined manner, so as to form a screw channel. Each retaining element is in the screw channel.
