Description

Technical Field

[0001] This utility model belongs to the technical field of water conservancy engineering, specifically relating to a bridge or culvert for easy passage in river channels. Background Technology

[0002] With the continuous advancement of urbanization and the increasing demand for comprehensive utilization of water resources, bridges and culverts on rivers play a vital role in transportation and water conservancy. In traditional river bridge and culvert designs, multiple circular culvert openings are usually set inside the bridge or culvert body. Water flows through these circular culvert openings to flow downstream, thereby realizing the drainage and water passage functions of the river.

[0003] However, in actual use, culverts face many problems. On the one hand, because river water often contains a large amount of garbage and aquatic plants, these impurities easily accumulate inside the circular culvert when water flows through it, eventually causing localized blockages. Once a circular culvert becomes blocked, it not only affects the normal drainage function of the river, leading to rising water levels, but may even cause flooding during the flood season, posing a serious threat to the lives and property of people in the surrounding areas.

[0004] On the other hand, the large amount of garbage and aquatic plants floating on the water surface also increases the difficulty of river cleaning. Traditional river cleaning methods usually require a lot of manpower, resources, and time, and the cleaning results are often unsatisfactory. Especially in some rivers with relatively fast currents, garbage and aquatic plants are easily washed away by the current, making effective cleaning difficult. This not only affects the aesthetics of the river, but may also damage the aquatic ecosystem.

[0005] To address these issues, there is an urgent need for a new type of bridge and culvert design for waterways that facilitates passage, effectively intercepts garbage and aquatic plants in the water flow, prevents blockage of circular culverts, reduces the difficulty of waterway cleaning, and improves the drainage efficiency and ecological environment quality of waterways. Utility Model Content

[0006] The purpose of this utility model is to provide a bridge or culvert for easy passage in waterways, in order to solve the problems mentioned in the background art, where when water flows through a circular culvert, garbage and aquatic plants in the water can easily accumulate inside the circular culvert, causing local blockages over time. At the same time, a large amount of garbage and aquatic plants floating on the water surface also increases the difficulty of cleaning the waterway.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a bridge or culvert for easy passage in a river, comprising a bridge or culvert body and a plurality of circular culvert holes disposed inside the bridge or culvert body. The plurality of circular culvert holes are longitudinally arranged inside the bridge or culvert body and are equidistant from left to right inside the bridge or culvert body. A concrete circular culvert is fixed inside each of the plurality of circular culvert holes. The concrete circular culvert is flush with the front and rear ends of the bridge or culvert body, respectively. An interception and protection device is provided at the front end of the bridge or culvert body.

[0008] Preferably, the interception and protection device includes an anti-detachment frame, metal fixing rods, a bottom metal support plate, and anti-displacement blocks. Metal fixing rods are provided at the four corners of the front outer wall of the bridge culvert body. Multiple metal fixing rods are longitudinally fixed at the front end of the bridge culvert body. The front ends of the multiple metal fixing rods are connected to the anti-detachment frame. Multiple anti-displacement blocks are also equidistantly arranged on the front outer wall of the bridge culvert body. The multiple anti-displacement blocks are all located between the upper sides of the center of the circular culvert hole. The multiple anti-displacement blocks are arranged equidistantly from left to right. A bottom metal support plate is connected between the two metal fixing rods at the two bottom corners of the front end of the bridge culvert body.

[0009] Preferably, the anti-detachment frame and the multiple metal fixing rods, as well as the bottom metal support plate and the metal fixing rods, are all fixedly connected by welding. The outer walls of the anti-detachment frame, the metal fixing rods, the bottom metal support plate, and the anti-displacement block are all coated with paint for corrosion and rust prevention.

[0010] Preferably, the interception and protection device further includes a U-shaped handle, a rectangular interception cover, an interception plate, and water passage holes. Rectangular interception covers are provided between the multiple anti-displacement blocks and between the anti-displacement blocks and the metal fixing rod. Both the front and rear ends of the rectangular interception cover are open. An interception plate is provided inside the rear end of the rectangular interception cover, and water passage holes are densely distributed inside the interception plate.

[0011] Preferably, the number of rectangular intercepting covers is the same as the number of circular culvert holes, and there is a one-to-one correspondence between the multiple rectangular intercepting covers and the multiple circular culvert holes. The rectangular intercepting covers are located outside the front end of the circular culvert holes, and each of the multiple rectangular intercepting covers is provided with a U-shaped handle at its top.

[0012] Preferably, the anti-detachment frame blocks the front end of multiple rectangular interception covers, and the multiple rectangular interception covers are placed on the bottom metal support plate. The U-shaped handle can drive the rectangular interception covers to move up and down.

[0013] Preferably, a plurality of concrete piles are equidistantly arranged at the bottom of the bridge culvert body, and a bridge culvert road surface is provided at the top of the bridge culvert body.

[0014] Preferably, the bridge and culvert road surface is provided with shoulders at both ends, and traffic guardrails are provided at the top of both shoulders.

[0015] Compared with the prior art, this utility model provides a bridge and culvert for easy passage in waterways, which has the following beneficial effects:

[0016] This invention adds a novel interception and protection device to the front end of a culvert or bridge in the river channel for easy passage. The device consists of multiple rectangular interception covers fixed to the front ends of multiple circular culvert openings that allow water flow. The interception plates inside the rectangular covers are densely packed with water-passing holes. These holes ensure normal water flow while intercepting debris such as garbage and weeds. Simultaneously, the device effectively prevents debris from entering the circular culvert openings, avoiding blockages and ensuring smooth water flow in the river. This reduces cleaning and maintenance work due to blockages, lowering maintenance costs. When it is necessary to clean the intercepted debris, the rectangular interception covers can be easily lifted from the bottom metal support plate using a U-shaped handle, making operation convenient and quick. Due to the blocking effect of the anti-detachment frame, the rectangular interception covers will not accidentally detach during use, ensuring the stability of the interception.

[0022] 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.

[0023] This utility model provides, for example Figure 1-4 The diagram illustrates a bridge / culvert for easy passage in a river channel, comprising a bridge / culvert body 3 and multiple circular culvert openings 7 disposed within the bridge / culvert body 3. The bridge / culvert body 3 serves as the main frame of the entire bridge / culvert, stably supporting the weight of the bridge / culvert road surface 6, passing vehicles, and pedestrians. It also provides installation and protection space for the internal circular culvert openings 7 and concrete circular culverts 8. The multiple circular culvert openings 7 are longitudinally arranged throughout the bridge / culvert body 3, and are equidistant from left to right within the bridge / culvert body 3. This equidistant arrangement of the multiple circular culvert openings 7 allows for easy passage of river water. The water flow is evenly distributed through each culvert, avoiding excessively large or small local flows, ensuring the stability of the water flow and the drainage efficiency of the river. The circular culvert openings 7 provide precise installation positions for the concrete circular culverts 8, ensuring that each culvert is fixed and neatly arranged within the bridge / culvert body 3, facilitating smooth water flow. Concrete circular culverts 8 are fixed inside each of the multiple circular culvert openings 7, and are flush with the front and rear ends of the bridge / culvert body 3. The concrete circular culverts 8, made of concrete, have good sealing and durability, ensuring that river water flows smoothly through the culverts into the downstream area, reducing... With reduced water flow resistance and improved drainage efficiency, the concrete circular culvert 8 can withstand the long-term scouring and pressure of river water flow, making it less prone to damage and reducing the frequency of repairs and replacements, thus lowering maintenance costs. Multiple concrete piles 1 are evenly spaced at the bottom of the culvert body 3, extending deep into the riverbed to provide stable support for the culvert. This prevents displacement or tilting under the influence of water flow, vehicle traffic, and other external forces. Furthermore, in the event of natural disasters such as floods, the concrete piles 1 ensure the stability of the culvert, reducing the risk of it being washed away and protecting both banks of the river. To ensure smooth traffic flow and the safety of people's lives and property, the top of the bridge and culvert body 3 is equipped with a bridge and culvert road surface 6. The bridge and culvert road surface 6 provides a flat and solid passage surface for vehicles and pedestrians, ensuring traffic connection between the two sides of the river and facilitating people's travel and the transportation of goods. Both ends of the bridge and culvert road surface 6 are equipped with shoulders 5. The shoulders 5 are located on both sides of the bridge and culvert road surface 6, which can prevent vehicles from driving off the road surface, protect the bridge and culvert road surface 6 from damage, and extend the service life of the road surface. Both shoulders 5 are equipped with guardrails 4 at their tops. The guardrails 4 can prevent pedestrians from accidentally falling off the bridge and provide a safe walking environment for pedestrians.

[0024] like Figure 1 , Figure 3 and Figure 4 As shown, an interception and protection device 2 is installed at the front end of the bridge culvert body 3. The interception and protection device 2 includes an anti-detachment frame 9, metal fixing rods 14, a bottom metal support plate 15, and anti-displacement blocks 16. Metal fixing rods 14 are installed at the four corners of the front outer wall of the bridge culvert body 3. Multiple metal fixing rods 14 are longitudinally fixed at the front end of the bridge culvert body 3. The front ends of multiple metal fixing rods 14 are connected to the anti-detachment frame 9. Multiple anti-displacement blocks 16 are also equidistantly installed on the front outer wall of the bridge culvert body 3. Located between the center of the circular culvert opening 7, multiple anti-displacement blocks 16 are arranged equidistantly from left to right. A bottom metal support plate 15 is connected between two metal fixing rods 14 at the two bottom corners of the front end of the bridge culvert body 3. The anti-detachment frame 9 and the multiple metal fixing rods 14, as well as the bottom metal support plate 15 and the metal fixing rods 14, are all fixedly connected by welding. The outer walls of the anti-detachment frame 9, the metal fixing rods 14, the bottom metal support plate 15, and the anti-displacement blocks 16 are all painted for corrosion and rust prevention.

[0025] like Figure 1 , Figure 3 and Figure 4As shown, the interception and protection device 2 also includes a U-shaped handle 10, a rectangular interception cover 11, an interception plate 12, and water passage holes 13. Rectangular interception covers 11 are installed between multiple anti-displacement blocks 16 and between the anti-displacement blocks 16 and the metal fixing rod 14. Both the front and rear ends of the rectangular interception cover 11 are open. An interception plate 12 is installed inside the rear end of the rectangular interception cover 11, and the interception plate 12 is densely covered with water passage holes 13. The number of rectangular interception covers 11 is the same as the number of circular culvert holes 7, and there is a one-to-one correspondence between the multiple rectangular interception covers 11 and the multiple circular culvert holes 7. The rectangular interception covers 11 are located outside the front end of the circular culvert holes 7. The interception plate 12 at the rear end of the rectangular interception cover 11 is densely covered with water passage holes 13. When river water flows through, the water can flow smoothly through the water passage holes 13, while debris such as garbage and weeds, due to their large size, cannot pass through the water passage holes 13 and are thus intercepted inside the rectangular interception cover 11. The multiple rectangular interception covers 11... Each of the rectangular interceptor covers is equipped with a U-shaped handle 10 at the top. An anti-detachment frame 9 blocks the front end of multiple rectangular interceptor covers 11. The multiple rectangular interceptor covers 11 are placed on the bottom metal support plate 15. The U-shaped handle 10 can move the rectangular interceptor covers 11 up and down. The metal fixing rod 14, the anti-detachment frame 9, the bottom metal support plate 15, and the anti-displacement block 16 together form a stable frame structure. The anti-detachment frame 9 blocks the front end of the rectangular interceptor covers 11 to prevent the rectangular interceptor covers 11 from detaching forward under the impact of water flow. The bottom metal support plate 15 provides support for the rectangular interceptor covers 11 to keep them in a stable position. The anti-displacement block 16 prevents the rectangular interceptor covers 11 from shifting in the horizontal direction. When it is necessary to clean the intercepted impurities, the rectangular interceptor covers 11 can be easily lifted from the bottom metal support plate 15 through the U-shaped handle 10 for impurity cleaning. After cleaning, the rectangular interceptor covers 11 can be put back in their original position to continue to play their interception role.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
