Description

Technical Field

[0001] The utility model relates to the technical field of bridge engineering, and specifically relates to a composite bridge structure that can allow micro-rail and pedestrians to pass simultaneously. Background Art

[0002] The micro-rail transit system is a new type of driverless transit system that runs along a preset overhead track. It can play a great role in tourist attractions, integrating transportation, sightseeing and landscapes together to create the tourist characteristics of the scenic area and improve the tourist experience of visitors. This system requires a bridge structure to bear the weight of the vehicle and guide the walking direction of the vehicle, and provide an installation platform for power supply and dispatching equipment.

[0003] Deficiencies of the prior art:

[0004] Currently, both the micro-rail transit system and the cloud walkway set up bridge structures as the bearing support system. However, the investment cost of the bridge structure is relatively high. If two transportation systems are introduced simultaneously, it will cause excessive investment costs. Moreover, since bridge construction is a large-scale civil engineering behavior, it requires a certain floor area during the construction and operation processes. Independently adopting the above two transportation systems will affect the ecological environment. In addition, the cloud walkway and the micro-rail transit system set up independently can only play their own functions and cannot achieve the landscape superposition effect. Content of the Utility Model

[0033] Please refer to Figures 1-5As shown in the figure, the present utility model provides a technical solution for a composite bridge structure that allows simultaneous passage of micro rails and pedestrians: It includes a bearing platform 110 and pile foundations 120. Both the bearing platform 110 and the pile foundations 120 adopt reinforced concrete structures. A bridge pier 130 is connected above the bearing platform 110. The bearing platform 110 is supported by the pile foundations 120. The top of the bearing platform 110 needs to be buried at a certain depth below the ground. The pile foundations 120 adopt circular piles, and the sizes of the bearing platform 110 and the pile foundations 120 are determined according to the geological conditions. The bearing platform 110 and the pile foundations 120 can be prefabricated in a factory first; the bridge pier 130 is connected with a micro rail track beam assembly 140, and a pedestrian passage assembly 150 is arranged below the micro rail track beam assembly 140 on the bridge pier 130. The bridge pier 130 includes an upper bridge pier column 131, a lower bridge pier column 133, and a pier column partition 136. Bridge pier cantilevers 132 are connected to both sides of the upper bridge pier column 131. A cantilever partition 137 is installed inside the bridge pier cantilevers 132. One side of the bridge pier cantilever 132 is fixedly connected to the upper bridge pier column 131, and the other side of the bridge pier cantilever 132 projects outward and is connected to the micro rail track beam assembly 140 through a cantilever lifting lug 1321 and a pin shaft. The bridge pier cantilever 132 is used to support the micro rail track beam assembly 140. The lower bridge pier column 133 is connected to the upper bridge pier column 131 through an upper connecting plate 134 of the lower bridge pier column and a lower connecting plate 135 of the upper bridge pier column. The lower bridge pier column 133 is connected to the bearing platform 110 through a lower connecting plate 138 of the lower bridge pier column. All can be fixed by high-strength bolts or welding. The bridge pier 130 is divided into an upper bridge pier column 131 and a lower bridge pier column 133, which is convenient for manufacturing and transportation. And the cross-section of the lower bridge pier column 133 is larger than that of the upper bridge pier column 131. A number of pier column partitions 136 are longitudinally and spacedly installed on both the upper bridge pier column 131 and the lower bridge pier column 133; the pedestrian passage assembly 150 is arranged below the micro rail track beam assembly 140, which meets the requirements of pedestrian passage and can be used as an evacuation passage for the micro rail at the same time, and can reduce the occupation of land resources and the damage to the ecological environment during construction.

[0034] Furthermore, the micro rail track beam assembly 140 includes a track beam top plate 141, a track beam web 142, a track beam bottom plate 143, and a track beam bottom plate stiffener 144.

A number of track beam circular stiffeners 145 are longitudinally and spacedly arranged on the outside of the track beam web 142. The track beam circular stiffeners 145 can resist local deformation of the micro rail track beam assembly 140, and the whole can be prefabricated in a factory and then transported to the site for assembly, improving the construction efficiency.

[0035] Further, the pedestrian passage component 150 includes a pedestrian passage main beam 151, a pedestrian passage support cantilever 152, a pedestrian passage cantilever stiffening plate 154, and a stainless steel grille 155. The pedestrian passage main beam 151 is disposed on the lower pier column 133 of the pier. The pedestrian passage main beam 151 is a closed box structure, welded by a top plate, a bottom plate, and a web plate. And several pedestrian passage main beam stiffening plates 156 are welded inside the pedestrian passage main beam 151. One end with a lower cross-sectional height of the pedestrian passage support cantilever 152 is connected to the pedestrian passage main beam 151. The pedestrian passage support cantilever 152 is formed by welding two T-shaped beams. The pedestrian passage support cantilevers 152 are arranged at intervals longitudinally along the pedestrian passage main beam 151. The pedestrian passage cantilever stiffening plate 154 is connected to the pedestrian passage support cantilever 152 and disposed on the pedestrian passage main beam 151. The stainless steel grille 155 is installed inside the guardrail 153 and disposed on the pedestrian passage main beam 151. One end with a higher cross-sectional height of the pedestrian passage support cantilever 152 is connected with a guardrail 153.
