OVERPASS BRIDGE CONSTRUCTION METHOD USING BOX TYPE UNDERPASS STRUCTURE

摘要

In the construction of the overpass which transversely crosses the upper part of the tunnel part of the box-shaped underground roadway divided into the tunnel part and the connection part, it is possible to construct using the box-shaped underground roadway as the lower part of the overpass road, A method of constructing an overhead road using a box-shaped underground roadway, comprising the steps of: constructing a tunnel portion and a connecting portion by connecting the tunnel portion and the connecting portion in a vertical direction using a U-shaped segment box below the ground GL; And a pair of upper and lower shift sections integrally formed on the upper surface of both side walls of the U-shaped segment box installed in the tunnel section above the ground (GL), and a slab is installed between the two alternating sections, And a step of constructing.
