Assembly type underground pedestrian path unit and assembly and underground pedestrian path

The utility model discloses a fabricated underground pedestrian path unit, a fabricated underground pedestrian path assembly and an underground pedestrian path. The underground pedestrian path unit comprises a U-shaped component which is mainly formed by integrating two side plates and a connecting plate, the top end faces of the two side plates are each provided with a first mounting hole for thecorresponding prestressed component to extend in, and first hand holes communicating with the corresponding first mounting holes are formed in the inner side faces of the side plates. Second mountingholes for the prestressed components to extend in are formed in the lower parts of the two side end surfaces of the side plates; second hand holes communicated with the corresponding second mountingholes are formed in the inner side surfaces of the side plates; the first mounting holes are vertically formed, and the second mounting holes are consistent with the underground pedestrian path in thelength direction.
