Abstract

The utility model provides a corrugated steel concrete arched bridge, includes bridge floor, a plurality of support column and bridge arch, the bridge arch sets up under the bridge floor, a plurality of support columns are established between bridge arch and the bridge floor, the bridge arch includes corrugated steel layer and concrete layer, concrete layer pours on corrugated steel layer. The utility model discloses a corrugated steel concrete arch bridge through hoisting corrugated steel layer earlier as the partly that the bridge encircles, has avoided occuping below highway when buildding, and this kind of method of buildding is more efficient than traditional method, and the bridge encircles intensity stronger, and spreading value is high.

Description

Corrugated steel concrete arch bridge

Technical Field

The utility model relates to a corrugated steel concrete arch bridge belongs to the bridge construction field.

Background

The overpass bridge is a common highway road bridge type, generally, the bottom of the bridge is a highway, and vehicles can pass through the bridge.

However, when the existing overpass bridge is built, the existing overpass bridge needs to occupy roads on an expressway below the overpass bridge to build a bridge foundation part, the expressway is bound to be closed for a period of time, and if the construction efficiency caused by an unexpected situation is low, the use influence on the expressway is particularly large, and intercity traffic is hindered.

Disclosure of Invention

The utility model provides a corrugated steel concrete arched bridge, its purpose is in order to solve current overline bridge and build the problem that can influence below highway and use, through hoisting out a corrugated steel layer earlier, has both avoided occuping highway, has strengthened bridge arch intensity again greatly.

The utility model provides a corrugated steel concrete arched bridge, includes bridge floor, a plurality of support column and bridge arch, the bridge arch sets up under the bridge floor, a plurality of support columns are established between bridge arch and the bridge floor, the bridge arch includes corrugated steel layer and concrete layer, concrete layer pours on corrugated steel layer.

Further, the radian of the concrete layer is consistent with that of the corrugated steel layer.

Further, the bridge arch is arranged between the bridge guiding walls.

The utility model has the main advantages that: the utility model discloses a corrugated steel concrete arch bridge through hanging corrugated steel layer earlier as the partly that the bridge encircles, has avoided occuping below highway when buildding, and this kind of method of buildding is more efficient than traditional method, and the bridge encircles intensity stronger, and spreading value is high.
