In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Embodiment one

As shown in Figure 1, the present embodiment provides an urban underground passage, including a bottom plate 1, a vertical plate 2 and a cantilever structure 3, a vertical plate 2 is fixedly arranged at both ends of the top surface of the bottom plate 1, and the cantilever structure 3 includes a horizontally arranged The top of each vertical plate 2 is fixed inwardly with a cantilevered plate 4, an opening is left between the two cantilevered plates 4, an underground driveway 5 is arranged above the bottom plate 1, and a cantilevered plate 4 is arranged above the cantilevered plate 4. There are 6 overground lanes.

In the urban underground passage in this embodiment, when the tunnel is buried shallowly, through the setting of the bottom plate 1, the vertical plate 2 and the cantilever structure 3, the underground traffic lane 5 and the ground traffic lane 6 are three-dimensionally arranged, saving the city. For land use, an opening communicating with the outside is provided between the two cantilevered plates 4, which can introduce natural light and ventilation to the underground driveway 5, and improve the driving comfort of the underground driveway 5. The above-ground roadway 6, while providing support for the above-ground roadway 6, is also a barrier for the noise of underground traffic and traffic, greatly reducing the interference to residents along the two sides.

As shown in Figure 1, the end of the underground driveway 5 laterally close to the vertical plate 2 is provided with drainage side ditches 7, and a water collection tank is provided at intervals below the bottom plate 1, and the drainage side ditch 7 is used to drain the underground driveway 5 The water (such as rainwater, etc.) on the ground is discharged and collected into the sump, and the water collected in the sump is discharged to the drainage pipe on the ground through the pumping device.

As shown in FIG. 1 , a safety protection facility 8 is provided at the inner end of the cantilever structure 3 . In this embodiment, the safety protection facility 8 is fixedly arranged at one end of the cantilever plate 4 to ensure the safety of ground vehicles.

As shown in Figure 1, the bottom surface of the base plate 1 is fixedly provided with an anti-floating device 10, and the anti-floating device 10 is an anti-floating pile. The urban underpass in the center provides anti-floating effect.
