The first double arch structure 1 and the second double arch structure 2 are spaced on the base 100 above the bridge 300 for hanging the slings 200.
The double arch rib structure is adopted, the first double arch rib structure 1 and the second double arch rib structure 2 are arranged in parallel, the transverse strut assembly 3 is adopted to support the first double arch rib structure 1 and the second double arch rib structure 2, the bearing capacity of the arch bridge can be effectively improved, the top of each arch rib is the area with the largest deformation, the second transverse strut support 32 is a Chinese character 'mi' shaped support, the tops of the first double arch rib structure 1 and the second double arch rib structure 2 are supported through the second transverse strut support 32, the area required to be supported is large due to the fact that the waist stress of each arch rib is not large, the first transverse strut support 31 and the third transverse strut support 33 are K-shaped supports, the waist of each first double arch rib structure 1 and each second double arch rib structure 2 are supported through the first transverse strut support 31 and the third transverse strut support 33, the bearing members 4 of each first transverse strut support 31, each second transverse strut support 32 and each third transverse strut support 33 serve as main bearing parts, the bearing capacity of each bearing member 4 is reinforced through the reinforcing members 5, and the structural strength of the arch bridge arch rib structure is guaranteed, and the safety of the arch bridge arch structure is improved.
Alternatively, the force-bearing member 4 includes a steel pipe 41 and a first concrete layer 42 provided inside the steel pipe 41. The first concrete layer 42 may be self-compacting shrinkage-compensating high-strength concrete, and the self-compacting shrinkage-compensating high-strength concrete is filled into the steel pipe 41, and since the steel pipe 41 is not provided with concrete vibrating construction, the self-compacting is adopted, and the conventional concrete has shrinkage, which causes the arch rib cross brace steel pipe 41 to have a gap locally, thereby forming a weak part, the self-compacting shrinkage-compensating high-strength concrete is required, and finally, the high-strength concrete is required to be used in order to ensure a certain strength. Alternatively, the steel pipe 41 is a seamless steel pipe. The seamless steel pipe is formed by perforating a whole round steel, and the surface of the seamless steel pipe is free of welding seams.
Since the reinforcing members 5 mainly play a role of reinforcing the wale assembly 3, and the number of the reinforcing members 5 is large, if the inside of the reinforcing members 5 is filled with concrete, the filling difficulty is large, and the implementation is not provided. Alternatively, the reinforcing member 5 includes an outer tube 51, an inner tube 52, and a first stiffening plate 53, the outer tube 51 and the inner tube 52 being coaxially disposed, the first stiffening plate 53 being disposed between the outer tube 51 and the inner tube 52. The use of the first stiffening plate 53 to support the outer tube 51 and the inner tube 52 enhances the load carrying capacity of the reinforcing member 5. To further support the outer tube 51 and the inner tube 52, the reinforcing member 5 may optionally further comprise a second stiffening plate 54, the second stiffening plate 54 being arranged between the outer tube 51 and the inner tube 52, the second stiffening plate 54 and the first stiffening plate 53 being perpendicular to each other.

The corrugated steel pipe is a metal corrugated pipe prepared from steel, is provided with a plurality of cylindrical thin-wall corrugated shells with transverse corrugations, has elasticity, can generate displacement under the action of pressure, axial force, transverse force or bending moment, and mainly plays roles in compensating thermal deformation of a pipeline, damping, absorbing sedimentation deformation of the pipeline and the like.
In order to enhance the strength of the connection between the first double arch rib structure 1 and the second double arch rib structure 2, optionally, a diagonal tie 6 is provided between the first double arch rib structure 1 and the second double arch rib structure 2. The cable-stayed connecting rods 6 can be crossed to form a stable triangle structure. Optionally, a second concrete layer 7 is provided within both the first double arch rib structure 1 and the second double arch rib structure 2. The second concrete layer 7 may be self-compacting shrinkage-compensating high-strength concrete, and the self-compacting shrinkage-compensating high-strength concrete is filled into the first double arch rib structure 1 and the second double arch rib structure 2 to increase the self weight of the arch ribs, thereby obtaining higher stability.
To prevent the arch bridge rib structure from being damaged by corrosion, an anti-corrosion layer is optionally provided on each of the first double rib structure 1, the second double rib structure 2 and the cross brace assembly 3. Optionally, the anticorrosive layer comprises a lower layer, a lower middle layer, a middle layer, an upper middle layer and an upper layer, wherein the lower layer is inorganic zinc-rich paint, the lower middle layer is zinc-aluminum alloy, the middle layer is vinyl epoxy anticorrosive paint, the upper middle layer is epoxy Yun Tieqi, and the upper layer is polyurethane paint. The inorganic zinc-rich paint takes inorganic polymer (such as silicate, phosphate, dichromate, etc.) as film forming substance, zinc powder reacts with the film forming substance to form zinc-iron complex on the surface of metal, thus forming solid protective coating. Because the inorganic zinc-rich paint adopts a large amount of high-purity and fine-particle zinc powder filler, the electrochemical protection effect can be achieved. Zinc is more negative than iron and the zinc atoms are liable to lose electrons in the electrolyte solution. The coating is destroyed locally, and the steel surface is not corroded, because zinc plays a role of a sacrificial anode, electrons are lost in the anode region, and electrons are obtained in the cathode region, so that the steel is protected. The epoxy Yun Tieqi can be a two-component self-drying paint, one component paint consists of medium molecular epoxy resin, special resin, zinc powder, auxiliary agent, diluent and the like, and the other component is an amine curing agent. Polyurethane paint is polyurethane paint, and has the following advantages: the paint film is tough, glossy, strong in adhesive force, waterproof, wear-resistant and corrosion-resistant. For the inner surface of a member which cannot be coated after welding, the anti-corrosion coating is finished before welding, and the welding part is coated and reinforced after welding.
