Problems solved by technology

However, the double helix arch has an enveloping effect on the bridge deck, which affects the driving vision
In addition, the construction of the two intersecting double helix space arches and the space cable network system arranged on the arches is also difficult, which is not conducive to the practical application of this type of bridge

Abstract

The invention discloses a single spiral arch and a suspension cable combined bridge structure system, comprising a bridge deck system, a spiral arch, a sling and a suspension cable; the single spiralarch and the suspension cable combined bridge structure system comprises a bridge deck system, a spiral arch, a sling and a suspension cable. A single spiral arch is longitudinally wound around the bridge deck system, and the bottom of the spiral arch is supported on the pile caps under the bridge deck system. A support is arranged at the bottom of the lateral surface of the bridge deck system, and the support is supported on the support located on the inner side of the spiral arch. The upper end of the sling is fixedly connected with the spiral arch dome above the bridge deck system, and thelower end is fixedly connected with the longitudinal central axis of the bridge deck system. The suspension cables arranged on both sides of the bridge deck system are anchored on the spiral arch andthe ends of the bridge deck system correspondingly. The utility model has the advantages of beautiful shape, good driving field of vision, convenient construction, and safe and stable overall structure.

Description

technical field [0001] The invention belongs to the technical field of bridge structures, and in particular relates to a bridge structure system combined with a single spiral arch and suspension cables. Background technique [0002] Spiral arch bridge is a novel space arch bridge. The foreign spiral arch bridge has Singapore Double Helix Bridge. This bridge is a pedestrian bridge with a total length of 280m. Two spiral curves are intertwined to form the main stress system of the bridge span structure. [0003] The domestic spiral arch bridge is Sanshan Bridge in Beijing. The bridge has two-way 4 lanes, sidewalks on both sides, and a total length of 452m. The Sanshan Bridge also adopts a double spiral arch structure. The bridge structure is suspended by high-strength steel cables, and the corrugated surface formed by the steel cables encloses the interior space of the bridge. [0004] The double-helix arch structure of the spiral arch bridge is not only novel and beautiful i...
