Problems solved by technology

There are some shortcomings in this bridge deck structure: the non-motor vehicle system and the pedestrian system are all slow systems, and it is not easy to manage on the same plane as the motor vehicle lanes of the fast system; it cannot ensure the safety of pedestrians and non-motor vehicles Safety issues; the climbing height of sidewalks and non-motor vehicle lanes is the same as that of the driving lane. When the climbing height of the driving lane is high, it is relatively difficult for pedestrians and non-motor vehicles to move; in urban traffic, the bridge width of urban bridges is relatively wide. On non-motor vehicle lanes, sidewalks and green belts and other structures, the width can reach 50m or even wider

Embodiment 1

[0017] Such as figure 1 As shown, the "similar double-layer" bridge structure disclosed in this embodiment is a "similar double-layer" prestressed concrete equal-height section box girder bridge structure, and its composition includes: on the basis of a conventional box girder, at the bottom of the box girder Add outer cantilever beam 2 and inner cantilever beam 3. The bridge deck 1 on the top plate of the box girder is used for arranging traffic lanes, the outer cantilever beam 2 can be used for arranging sidewalks and non-motor vehicle lanes, and the inner cantilever beam 3 can be used for arranging telecommunications, electric power, tap water pipelines, etc., to bring into play its comprehensive benefits; The outer cantilever beam 2 is provided with a railing 4 on the outer edge to ensure the safety of pedestrians and bicycles;

[0018] In this example:

[0019] The "like double-layer" prestressed concrete box girder with equal height section is a single box with double ...

Embodiment 2

[0021] Such as figure 2 As shown, the "similar double-layer" bridge structure disclosed in this embodiment is a "similar double-layer" hingeless arch bridge, and the main bridge is set as a "similar double-layer" structure, including the main arch ring 7 and the cross brace 10 , the main arch ring 7 is a steel box section, a flexible suspender 8 is set to hang the steel beam 9, and bears the dead load and live load of the bridge deck 5, and the steel beam 9 is connected with the sidewalk cantilever beam 6 to form a whole. The bottom bridge deck is exclusively for pedestrians and non-motor vehicles to realize the separation of pedestrians and vehicles.

[0022] In this example:

[0023] The sidewalks and non-motorized lanes are designed to be lower than the traffic lanes, because the load is small and no high building height is required, thus forming a pedestrian-vehicle branch bridge structure, that is, the traffic lanes are independent in the middle, and the sidewalks and n...

Abstract

The invention discloses a bridge structure similar to a double-layer structure. The bridge structure comprises a bridge main body, wherein two layers of an upper bridge floor and a lower bridge floor are arranged on the bridge main body, the upper bridge floor is a motor way, the lower bridge floor is a non-motor way and a pedestrian way, and the lower bridge floor is moved downwards to the outer side of the bottom of a bridge after lowering treatments, so that pedestrians and motor vehicles are completely separated; balustrades are arranged on the outer edge of the lower bridge floor, so that safety of the pedestrians and non-motor vehicles is ensured. The bridge floors are staggered, elevations of the non-motor way and the pedestrian way are lowered, and the non-motor way and the pedestrian way are moved downwards to the outer side of the bottom of the bridge, so that the bridge structure similar to the double-layer structure is formed, layered passing of the pedestrians and the motor vehicles are realized, and climbing heights of the non-motor vehicles and the pedestrians are shortened; a longitudinal slope of the motor way is suitably prolonged, so that the length of the bridge is greatly shortened; the safety of the pedestrians and the non-motor vehicles is ensured, besides, interference to the motor vehicles is also avoided during driving, and the driving is smoother; a space is effectively and reasonably utilized.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a "similar double-layer" bridge structure. Background technique [0002] At present, under normal circumstances, the road width composition of the bridge structure is: motor vehicle lane + non-motor vehicle lane + sidewalk, and the motor vehicle lane, non-motor vehicle lane and sidewalk are on the same plane. There are some shortcomings in this bridge deck structure: the non-motor vehicle system and the pedestrian system are all slow systems, and it is not easy to manage on the same plane as the motor vehicle lanes of the fast system; it cannot ensure the safety of pedestrians and non-motor vehicles Safety issues; the climbing height of sidewalks and non-motor vehicle lanes is the same as that of the driving lane. When the climbing height of the driving lane is high, it is relatively difficult for pedestrians and non-motor vehicles to move; in urban traffic, the b...
