Supporting rod is equipped with the arch clad steel corrugated plating of multigroup splicing；The spandrel arch is made of arch clad steel corrugated plating.
Further technical solution is：Road surface is laid on the arch fill layer.
Further technical solution is：The arch fill layer is bankets or concrete.
Further technical solution is：The support is prestressed steel bar, steel strand wires or supporting steel plate.
Further technical solution is：Connecting method between every two groups of clad steel corrugated platings is grafting, after grafting
It is fixed with bolt, the nut-welding of the bolt is on the outside of clad steel corrugated plating.
Further technical solution is：Seam crossing perfusion high-strength structure between every two groups of clad steel corrugated platings
Glue.
Further technical solution is：The clad steel corrugated plating includes steel corrugated plating, the interior outside table of the steel corrugated plating
Face is all provided with multifunctional anticorrosive environment-friendly coating.
Further technical solution is：The tubular arch and supporting rod surface spraying have high molecular polymer anticorrosive paint.
It is using advantageous effect caused by above-mentioned technical proposal：
(1) bearing structure of bridge main arch is assembled by multigroup clad steel corrugated plating, add supporting structure by
Power area, bearing capacity is strong, and use is banketed or concrete is as the upper fill stratum of arch, not only saves cost and can prevent
Only it is uneven so as to causing the harm such as bumping at bridge-head to there is sedimentation for the basis of bridge and both sides roadbeds；
(2) spandrel arch is made of the clad steel corrugated plating of arch, alleviate bridge weight and filler to side wall pressure, increase
Big bridge water amount；
(3) clad steel ripple plate surface is equipped with multifunctional anticorrosive environment-friendly coating, adds corrosion resistance, and multi-functional anti-
Rotten environment-friendly coating can be repaired in the later stage, is solved clad steel corrugated plating surface anticorrosion layer during transport, installation and is damaged
Problem；
(4) tubular arch and supporting rod surface spraying have high molecular polymer anticorrosive paint, prevent from effectively preventing corrosion, extend
The service life of arch bridge reduces or eliminates maintenance cost.
