Description
Technical Field
The invention relates to an arch bridge structure, in particular to a hollow steel pipe concrete arch bridge structure.
Background
The steel pipe concrete combined arch bridge is a common arch bridge structure form, and is usually formed by combining a steel pipe and concrete.
At present, the common large-span concrete filled steel tube arch bridge is formed by filling concrete in a steel tube, and has the advantages of simple structure and strong bearing capacity. But the self weight is heavier, the concrete pouring amount is large, and the construction is not convenient. Therefore, it is necessary to design a concrete filled steel tube arch bridge structure which has the advantages of simple structure, strong bearing capacity, low cost and convenient construction.
Disclosure of Invention
The invention aims to provide a hollow steel pipe concrete arch bridge structure. The invention has the characteristics of simple structure, strong bearing capacity, low cost and convenient construction.
The technical scheme of the invention is as follows: a hollow steel tube concrete arch bridge structure comprises a plurality of steel tube concrete main chord tubes arranged in parallel and web members connected with the steel tube concrete main chord tubes; the steel pipe concrete main chord pipe comprises an outer layer steel pipe, an inner layer steel pipe is arranged at the axis of the outer layer steel pipe, and concrete is filled between the outer layer steel pipe and the inner layer steel pipe.
In the hollow steel pipe concrete arch bridge structure, the upper side of the outer layer steel pipe is provided with the pouring gate.
According to the hollow steel pipe concrete arch bridge structure, the pouring blanking pipe is arranged above the pouring gate.
In the hollow steel pipe concrete arch bridge structure, the sectional area of the inner layer steel pipe is 50% of that of the outer layer steel pipe.
The invention has the advantages of
1. According to the invention, the steel pipe is designed into an inner-outer double-layer structure, and concrete is filled between the outer-layer steel pipe and the inner-layer steel pipe, so that the whole structure has the advantages of simple structure and low manufacturing cost.
2. Aiming at calculating the span 482m, the arch axis adopts a catenary, the arch axis coefficient m is 1.6, the rise h is 96.4m, and the rise-span ratio f is 1/5, and the theoretical comparative analysis is carried out on the hollow rate of 50% and the solid steel pipe concrete. Under the same condition, the structure of the invention is analyzed by theoretical calculation, compared with solid steel tube concrete, the bearing capacity is reduced to some extent, but with the reduction of self-weight, the internal force of the hollow steel tube concrete under the load action is reduced, and the bearing capacity calculation requirement of the specification requirement can be met after the hollow steel tube concrete replaces the solid steel tube concrete in the steel tube concrete arch bridge obtained by the bearing capacity checking result. In the deflection comparative analysis, the difference of the deflection of the hollow steel tube concrete and the deflection of the solid steel tube concrete at the same position is not obvious.
3. The hollow steel tube concrete arch bridge structure has the advantage of convenience in construction on the basis of reducing the self weight.
4. The self-weight of the main arch ring structure is reduced, and simultaneously, the load borne by the arch base is also reduced, so that the volume of the arch base can be reduced, the excavation amount is reduced, and the protection of the ecological environment nearby a bridge area is facilitated.

Detailed Description
The present invention is further illustrated by the following examples, which are not to be construed as limiting the invention.
Examples of the invention
A hollow concrete-filled steel tube arch bridge structure is shown in attached figures 1-3 and comprises a plurality of concrete-filled steel tube main chord tubes 7 which are arranged in parallel and web members 6 which are connected with the concrete-filled steel tube main chord tubes 7; the steel pipe concrete main chord pipe 7 comprises an outer layer steel pipe 1, an inner layer steel pipe 2 is arranged at the axis of the outer layer steel pipe 1, and concrete 3 is filled between the outer layer steel pipe 1 and the inner layer steel pipe 2.
During construction, the inner steel pipe 2 is firstly placed into the outer steel pipe 1, the inner steel pipe 2 and the outer steel pipe 1 are coaxial, then the positions of the inner steel pipe 2 and the outer steel pipe 1 are fixed by using a cushion block or welding a support rod at a gap, and then concrete 3 is poured into the gap between the inner steel pipe 2 and the outer steel pipe 1.
The upper side of the outer layer steel pipe 1 is provided with a pouring gate 4, and the pouring gate 4 is used for pouring concrete, so that the steel pipe concrete main chord pipe 7 can normally complete pouring construction no matter in prefabrication or site construction.
And a pouring blanking pipe 5 is arranged above the pouring gate 4, the pouring blanking pipe 5 is used for facilitating the pouring process, the falling fall of concrete is improved, and the compactness of the concrete 3 between the inner-layer steel pipe 2 and the outer-layer steel pipe 1 is improved.
The sectional area of the inner steel pipe 2 is 50% of that of the outer steel pipe 1.
The above description is only for the purpose of illustrating the present invention and the appended claims, and the scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
