[0002] As key hubs in the transportation network, roads and bridges play a vital role in flood prevention and control. Ensuring the unimpeded flow of roads and bridges during floods is crucial for the timely transport of relief supplies, the evacuation of affected people, and the rapid commencement of post-disaster reconstruction. Furthermore, to enhance the safety of roads and bridges, it is necessary to utilize flood-resistant road and bridge structures that improve their flood control efficiency.

[0003] A flood control road bridge structure is disclosed in the existing authorized publication number CN213173309U. This utility model includes a road surface and four bridge piers, which are located on both sides of the road surface. A V-shaped beam is provided on the top of the bridge pier, and the top of the V-shaped beam is fixed to the top surface of the bridge pier. A crossbeam is fixed between the bridge piers on both sides of the road surface. A steel structure road frame is erected on the crossbeam. The road surface is laid on the upper surface of the steel structure road frame. The road surface is paved with permeable asphalt. Rainwater collection pipes are pre-embedded in the road surface. The rainwater collection pipes have collection holes. The length direction of the rainwater collection pipes is perpendicular to the length direction of the road surface. There are multiple rainwater collection pipes and they are evenly distributed along the length direction of the road surface.

[0004] However, due to the poor reinforcement and support capabilities of the existing patent technology with authorization announcement number CN213173309U, it is not convenient to effectively reinforce and support roads and bridges in actual use. The bridge piers are directly installed on the ground, and after long-term use, it is not convenient to effectively resist the impact of floods on the bridge body during the flood season, thus affecting the safety of the bridge.

[0006] The purpose of this utility model is to provide a flood control road and bridge structure to solve the problem mentioned in the background art that the existing technology is not convenient for effectively reinforcing, installing and supporting road and bridge operations.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a flood control road bridge structure, including a bridge body pavement, with several connecting plates evenly and movably installed on both sides of the bridge body pavement, connecting seats fixedly installed on the opposite sides of the connecting plates, and adjusting and reinforcing rods fixedly installed on the opposite sides of the connecting seats. Two support blocks are movably installed on the side of the adjusting and reinforcing rod away from the connecting seats, and support base blocks are fixedly installed at the bottom ends of the two support blocks. A support connecting shaft is rotatably connected to the middle of the support blocks, and the support connecting shaft is rotatably connected through the middle of the adjusting and reinforcing rod.

[0009] Preferably, a mounting base plate is fixedly installed at the bottom end of the support block, and a fixing bolt is threadedly connected to the top end of the mounting base plate, the fixing bolt extending to the bottom end of the mounting base plate.

[0010] Preferably, a connecting through hole is provided on one side of the connecting plate, and a connecting bolt is movably connected to one side of the connecting through hole.

[0014] Preferably, mounting plates are fixedly installed on both sides of the cast-in-place bridge pier, and two mounting through holes are opened at the top of the mounting plates, with the two mounting through holes penetrating the mounting plates.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This flood control road bridge structure, through the installation of connecting plates, connecting seats, and adjusting reinforcement rods on both sides of the bridge surface, combined with a support system consisting of support blocks, support base blocks, and support connecting shafts, effectively enhances the bridge's reinforcement and support capacity. The support blocks and support base blocks disperse impact forces over a larger ground area, while the mounting base plate and fixing bolts under the support base blocks ensure the support structure is firmly fixed to the ground, preventing displacement. Compared to existing technologies that directly install bridge piers on the ground, this structure significantly improves the bridge's ability to withstand flood impacts, ensuring the bridge's operational safety.

[0017] 2. The flood control road and bridge structure features several drainage holes at the top of the bridge surface, with filter screens installed inside. This allows for the rapid drainage of water accumulated on the bridge, preventing erosion of the bridge structure. Simultaneously, flood control drainage holes evenly spaced along one side of the bridge assist in draining water accumulated on the bridge when flood levels rise, further improving drainage efficiency. This dual drainage design significantly enhances the bridge's drainage capacity during heavy rain or floods, effectively reducing the impact of water accumulation on vehicle and pedestrian traffic and ensuring the normal use of the road and bridge during the flood season.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4This utility model provides a technical solution: a flood control road bridge structure, including a bridge surface 1, with several connecting plates 2 evenly and movably installed on both sides of the bridge surface 1, connecting seats 3 fixedly installed on the two sides of the connecting plates 2 away from each other, and adjusting and reinforcing rods 4 fixedly installed on the two sides of the connecting seats 3 away from each other. Two support blocks 5 are movably installed on the side of the adjusting and reinforcing rods 4 away from the connecting seats 3, and a support base block 6 is fixedly installed at the bottom end of the two support blocks 5. A support connecting shaft 7 is rotatably connected to the middle of the support blocks 5, and the support connecting shaft 7 is rotatably connected through the middle of the adjusting and reinforcing rods 4. An installation base plate 8 is fixedly installed at the bottom end of the installation base plate 6, and a fixing bolt 9 is threadedly connected to the top end of the installation base plate 8. The fixing bolt 9 extends to the bottom end of the installation base plate 8. The impact force of floods is transmitted through the bridge surface 1 to the adjusting and reinforcing rods 4, and the adjusting and reinforcing rods 4 distribute the force to the support blocks 5, and then to the ground through the support base blocks 6. The large ground contact area is used to distribute the impact force, reduce the direct impact of floods on the bridge body, and improve the safety of flood control.

[0025] A connecting through hole 10 is provided through one side of the connecting plate 2, and a connecting bolt 11 is movably connected to one side of the connecting through hole 10. Protective bridges 12 are fixedly installed on both sides of the top of the bridge surface 1. Several flood control drainage holes 13 are evenly provided on one side of the protective bridge 12. Several drainage through holes 14 are evenly provided at the top of the bridge surface 1. Filter screens 15 are fixedly installed inside the drainage through holes 14. Support frames 16 are fixedly installed on both sides of the bottom of the bridge surface 1. Cast-in-place bridge piers 17 are fixedly installed at the bottom of the support frames 16. The middle of the support frames 16 is fixed... A reinforcing crossbeam 18 is fixedly installed. Mounting plates 19 are fixedly installed on both sides of the cast-in-place pier 17. Two mounting through holes 20 are opened at the top of the mounting plates 19. The two mounting through holes 20 pass through the mounting plates 19. Accumulated water flows down through the drainage through holes 14. The filter screen 15 inside the drainage through holes 14 can intercept leaves, debris and other objects to prevent them from clogging the drainage pipes. When the flood level rises and overflows to the protective bridge 12, the flood control drainage hole 13 on one side of the protective bridge 12 begins to play an auxiliary drainage role, and the accumulated water is discharged through the flood control drainage hole 13.

[0026] Working Principle: During daily use and before the flood season, construction personnel, based on the bridge's terrain and actual needs, securely install the connecting plate 2 on both sides of the bridge surface 1 by passing the connecting bolts 11 through the connecting through holes 10. Then, they adjust the angle of the adjusting reinforcement rod 4 to adapt to the ground conditions. Utilizing the rotating connection of the support connecting shaft 7 in the middle of the support block 5, the angle between the adjusting reinforcement rod 4 and the support block 5 can be flexibly changed. After determining the angle, the mounting base plate 8 at the bottom of the support base block 6 is placed in the appropriate position, and the fixing bolts 9 are tightened to firmly fix the entire support structure to the ground, completing the installation of the bridge reinforcement support structure. When floods occur during the flood season, the rapid water flow impacts the bridge. At this time, the support system consisting of the connecting plate 2, connecting seat 3, adjusting reinforcement rod 4, support block 5, and support base block 6 on both sides of the bridge surface 1 comes into play. The impact force of the flood is transmitted through the bridge surface 1 to the adjusting reinforcement rod 4, which then... The force is distributed to the support block 5, and then transferred to the ground through the support base block 6. The large ground contact area is used to distribute the impact force and reduce the direct impact of flood on the bridge. At the same time, the mounting base plate 8 and fixing bolts 9 under the support base block 6 ensure that the support structure will not be displaced due to flood impact, ensuring the stability of the bridge under flood impact. In terms of drainage, when it rains, the drainage hole 14 at the top of the bridge surface 1 starts to work. Under the action of gravity, the water on the bridge flows down through the drainage hole 14. The filter screen 15 inside the drainage hole 14 can intercept leaves, debris, etc., to prevent them from clogging the drainage pipe. When the flood level rises and overflows to the protective bridge 12, the flood control drainage hole 13 on one side of the protective bridge 12 begins to play an auxiliary drainage role. The water is discharged through the flood control drainage hole 13, further accelerating the drainage speed of the water on the bridge, reducing the water depth, ensuring that vehicles and pedestrians can still pass safely during the flood season, and improving the bridge's flood control capacity.

[0027] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
