Description

Spliced stainless steel carbon steel composite steel plate corrugated pipe culvert structure Technical Field The utility model relates to the technical field of corrugated pipe culverts, in particular to a spliced stainless steel carbon steel composite steel plate corrugated pipe culvert structure. Background The corrugated culvert is also called a metal corrugated culvert or a steel corrugated culvert, is a threaded corrugated pipe for a culvert which is buried under a highway or a railway, is connected in a sleeve or flange mode, can be customized in length according to requirements, can be operated even by unskilled workers, can be constructed by a small amount of manual operation, can be completed in a short time, can be spliced and connected, can be connected in a whole pipe, can be made into an arch shape, an ellipse shape, a horseshoe shape, a dustpan shape and the like to adapt to various requirements, and has the engineering cost which is lower than that of a bridge or a culvert with the same span by more than 15 times due to the unique corrugated structure. Through mass search, it is found that the corrugated culvert in the prior art usually adopts Q235 or SS400 hot rolled steel plates, the surface is hot dip galvanized, part of products can be coated with asphalt on a construction site to enhance the corrosion resistance, but a galvanized layer can still be corroded in a long-term saline alkali water, industrial wastewater or high humidity environment, asphalt needs to be additionally coated or thickened pipe walls are adopted, and the traditional corrugated culvert is usually connected only by virtue of flanges and bolts when being spliced, so that the sealing performance is limited.
