[0030] The abutment 1 is used to bear the entire bridge structure of the utility model and transfer loads, the top of the bridge deck 2 is used as a vehicle passage, and a pedestrian passage and a non-motor vehicle passage are opened inside the box.
[0031] Specifically, the abutment 1 is arranged at the junction of the urban dividing area. In this embodiment, the cross section of the envelope of the chamber 3 is an inverted isosceles trapezoid, which has a high structural strength. The chamber 3 is located between two adjacent abutments 1 and is arranged on the top of the abutment 1. The chamber 3 includes a web 31 and a bottom plate 32. The bottom ends of the two webs 31 are respectively fixedly connected to the two ends of the bottom plate 32, and the top ends of the two webs 31 are respectively fixedly connected to the bottom side of the bridge deck 2. Anti-collision walls 21 are arranged on both sides of the bridge deck 2 to reduce the possibility of vehicles running out of the bridge deck.
[0032] Compared with the existing technology, the utility model realizes the vertical separation of the motor vehicle lane and the non-motor vehicle pedestrian passage, improves traffic safety and the efficiency of motor vehicle passage, reduces conflicts between people and vehicles, ensures the safety of pedestrians and non-motor vehicles, and is more humane.
[0033] It should be noted that the utility model bridge structure adopts a superstructure box structure, and the box 3 cross section has high torsional rigidity and bending resistance, which can provide a large clearance in the box. By adjusting the outer contour beam height at the fulcrum and the width of the web 31, the clearance continuity, smoothness and force requirements in the box 3 can be guaranteed, thereby meeting the requirements for the passage of people and non-motor vehicles. The utility model structure not only provides a passage space for vehicles, but also has a special pedestrian passage and non-motor vehicle passage to meet the passage needs of pedestrians and non-motor vehicles.
[0034] Specifically, the clearance of chamber 3 passage is at least 2.5m, and the minimum clear width of chamber 3 passage is at least 3.75m.
[0035] like Figure 1 As shown, a plurality of columns 5 are evenly distributed and vertically fixedly connected to the top of the bottom plate 32 , and the anti-skid support plate 4 is fixedly connected to the top ends of the plurality of columns 5 .
[0036] Through the above technical solution, the anti-skid support plate 4 can effectively reduce the possibility of pedestrians slipping, and multiple evenly spaced columns 5 support the anti-skid support plate 4, which can make the anti-skid support plate 4 evenly stressed and increase the service life of the anti-skid support plate 4.
[0037] Preferably, the elevation of the anti-slip support plate 4 in the chamber 3 is kept consistent, and is effectively connected with both sides outside the abutment 1.
[0038] Preferably, in order to separate the pedestrian passage and the non-motor vehicle passage inside the box, the stopper 6 is arranged in the middle of the anti-slip support plate 4 .
[0039] Preferably, in order to keep the air inside the box fresh and improve the comfort of people when passing through the box, a plurality of ventilation holes 311 are opened in the middle of the web 31 .
[0040] Preferably, a plurality of light tubes 7 are arranged inside the chamber 3. In the present embodiment, the light tubes 7 are arranged at the top of the inner wall of the chamber 3. There are three rows of light tubes 7 in total. The three rows of light tubes 7 are evenly spaced and arranged along the length direction of the chamber 3 to provide lighting for pedestrians in the chamber 3 and reduce potential safety hazards in the chamber 3.
[0041] like Figure 3 and Figure 4 As shown, in this embodiment, the access ramp 8 is used to provide pedestrians or non-motor vehicles with access to the box chamber 3. The access ramps 8 are arranged in pairs, and the access ramps 8 take the width direction center axis of the bridge deck 2 as the mirror symmetry axis. The access ramps 8 are arranged on the outside of the abutment 1, and the angle between the access ramp 8 and the plane where the bridge deck 2 is located is an acute angle, so that non-motor vehicles or pedestrians can quickly enter the box body with the help of gravity; the platform 81 is fixedly connected to the bottom end of the access ramp 8, and the box chamber 3 is provided with an entrance and exit near the platform 81, so that the box body is connected in the width direction to form a passage;
[0042] The retaining wall 9 is vertically arranged at the outer edge of the access ramp 8 and the platform 81 to protect pedestrians.
[0043] It should be noted that, in other embodiments, the building structure for pedestrians or non-motor vehicles to enter and exit the box chamber 3 may be an overpass or an underground tunnel.
[0044] The utility model provides a channel transition section between the bridge section and the roadbed. In the channel transition section, pedestrians and non-motor vehicles enter the box chamber 3 after passing through the corresponding access ramp 8 outside the abutment 1 in turn according to traffic driving rules.
[0045] Preferably, a drainage outlet is provided at the bottom of the retaining wall 9 close to the outer side of the abutment 1 .
[0046] The bridge structure of this embodiment has the following advantages:
[0047] First, the vertical separation arrangement between the channels is realized. The utility model bridge structure vertically separates the vehicle channel and the pedestrian channel, thereby improving traffic safety and the efficiency of motor vehicle traffic, reducing conflicts between people and vehicles, ensuring the traffic safety of pedestrians, motor vehicles and non-motor vehicles, and being more humane.
[0048] Second, efficient space utilization is achieved. The utility model bridge structure utilizes the clearance and width advantages of the large box chamber 3 to provide a dedicated passage space for pedestrians and non-motorized vehicles, while optimizing the width of the bridge deck and improving the overall space utilization efficiency. Compared with the actual overall investment cost, it effectively reduces the cost by 20%, greatly reducing the investment cost.
[0049] Thirdly, the bridge structure of the utility model has better continuity and comfort. The construction personnel can ensure the continuity and smoothness of the clearance and the force requirements in the box 3 by adjusting the outer contour beam height at the fulcrum and the width of the web 31, thereby meeting the comfort requirements of pedestrians and non-motor vehicles.
[0050] Fourth, meet relevant technical specifications. According to the technical specifications for urban pedestrian overpasses and pedestrian tunnels, the minimum clearance and clear width of the passage in the control box room 3 can ensure the spaciousness and comfort of pedestrians and non-motorized vehicles.
[0051] Fifthly, the abutment 1 of the utility model not only bears the function of supporting and transferring loads, but also enhances the practicality and stability of the bridge structure of the utility model through external access ramps 8, retaining walls 9, platforms 81 and drainage outlets and other ancillary facilities.
[0052] Sixth, the utility model bridge structure realizes the optimization of the internal environment of the pedestrian passage and the non-motor vehicle passage. The design of the chamber 3 takes into account the vents 311, the light tube 7, the anti-slip support plate 4 and other facilities, which improves the traffic environment and improves the traffic safety and comfort under different weather conditions.
[0053] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
