Embodiment Construction
[0021] The present invention will be described in detail below in combination with specific embodiments.
[0022] The arc-arch steel corrugated plate bridge and culvert structure according to the present invention has a foundation 2 at the lower part, and adopts C30 reinforced cement concrete. The upper part of the foundation 2 is provided with a single-span or multi-span bridge arch, and the bridge arch is a steel corrugated plate arc arch 1, which is composed of steel corrugated plates assembled and fixed by bolts. Such as figure 1 For the three-span steel corrugated arch bridge culvert shown, the steel corrugated arch 1 has a radius of 2.1648m, a central angle of 135°, a radius of curvature of 4.33m, a single span of 4m, and a height of 1.3365m . The corrugation of the corrugated steel plate is axial corrugation, the wave shape is 150mm×50mm×28mm, and the thickness of the covering soil on the top of the plate is 1.08m. The arch spacing of the steel corrugated plate arc a...
