Relate to.

An underground roadway is an underground structure installed across a road or a railway so that a person or a vehicle can safely cross the road without interfering with the operation of a vehicle running on the road or railway.

As shown in FIG. 1, the underground driveway is composed of walls 20a on both sides spaced apart from each other, a lower slab 40a connecting the lower end of the wall 20a, and an upper end of the wall 20a Shaped upper slab 30a and serves as a lane dividing line for the safety of a passing vehicle.

A central separating wall or a plurality of central separating pillars 50 are installed to connect the upper slab 30a and the lower slab 40a along the direction of travel to reinforce the insufficient load bearing capacity of the long span upper slab.

These underground roads can be installed in the following order.

First, the ground is excavated in the direction of the underground roadway installation where the underground roadway should be constructed.

At this time, it is necessary to secure the stability of the excavated ground by providing a hysteresis such as a H pile and a soil plate or a sheet file on the ground. After the excavation is performed, the lower slab 40a is installed on the excavation bottom surface.

The reason for constructing the lower slab 40a first is to provide a horizontal slab capable of supporting the upper slab formwork. After the construction of the sewage slab is completed, So that the wall 20a is installed.
