Technical Field
[0001] The utility model relates to the technical field of culvert structures, in particular to a novel culvert structure. Background Art
[0002] As important transportation and water conservancy facilities, culvert structures play a crucial role in providing passages across rivers, valleys, and under roads. Traditional culvert designs usually include basic structural elements such as the longitudinal section, single-hole culvert plane, and wing walls, which together form the basic framework of the culvert. The longitudinal section serves as the main load-bearing structure of the culvert, and the wing walls play the role of guiding water flow and supporting the slopes.
[0003] Over time and with the development of technology, some limitations of existing culvert structures have gradually emerged in practical applications. The wing wall foundations of traditional culverts are usually not reinforced, resulting in easy damage under heavy traffic or extreme climate conditions. In addition, the waterproof and anti-corrosion measures of existing culverts are often insufficient, prone to leakage and structural degradation problems during long-term operation. The cut-off walls and entrance paving of the culverts also lack effective water flow control and anti-slip measures, which may affect the flood discharge capacity and service safety of the culverts under high flow or adverse weather conditions. Summary of the Utility Model

[0014] As a further description of the above technical solution:
[0015] The top of the curb is designed with a drainage groove to guide rainwater to both sides of the culvert and prevent water accumulation.
[0016] As a further description of the above technical solution:
[0017] The wing walls are designed with different inclination angles according to the terrain and water flow conditions to optimize the hydrodynamic characteristics.
[0018] As a further description of the above technical solution:

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0029] Refer to Figures 1-3 , an embodiment provided by the present utility model: a new culvert structure, including a longitudinal section 1, a plan of single-hole culvert 6 and a wing wall 8. A first wing wall foundation 2 is provided under the longitudinal section 1. There is a side wall body 3 on the upper right of the first wing wall foundation 2. A layer of hot asphalt 4 is provided on the first wing wall foundation 2. A water cut-off wall 5 is provided on the right side of the side wall body 3. An abutment paving 7 is provided under the plan of single-hole culvert 6. A kerbstone 9 is provided on the right side of the wing wall 8. A second wing wall foundation is provided under the wing wall 8. By using reinforced reinforced concrete to construct the first wing wall foundation and the second wing wall foundation, the overall bearing capacity and durability of the structure are significantly enhanced. This reinforcement design effectively improves the adaptability of the culvert to extreme climates and heavy traffic, extends its service life, and at the same time reduces the long-term maintenance and repair costs. By coating the outer surface of the first wing wall foundation with hot asphalt, an additional waterproof and anti-corrosion layer is provided, further ensuring the stability and durability of the structure.
[0030] Both the first wing wall 8 foundation - 2 and the second wing wall 8 foundation adopt reinforced reinforced concrete structures to enhance the bearing capacity and durability of the culvert. The application of a single coat of hot asphalt 4 covers the outer surface of the first wing wall 8 foundation - 2 to provide additional waterproof and anti - corrosion protection. The cut - off wall 5 is designed with a number of drainage holes to achieve effective water flow control. The paving 7 at the entrance of the single - hole culvert plane 6 uses anti - slip and wear - resistant materials to improve the passing safety of pedestrians and vehicles. The top of the curb 9 is designed with a drainage groove to guide rainwater to both sides of the culvert, preventing waterlogging. The wing wall 8 is designed with different inclination angles according to the terrain and water flow conditions to optimize the hydrodynamic characteristics. The connection between the wing wall 8 and the longitudinal section 1 adopts a special sealing structure to prevent leakage. The design of the cut - off wall introduces a number of drainage holes, through which effective control and guidance of water flow are achieved, optimizing the flood discharge capacity of the culvert under high - flow conditions. The anti - slip and wear - resistant materials used for the paving at the entrance of the single - hole culvert plane enhance the passing safety of pedestrians and vehicles under wet or adverse weather conditions. The drainage groove design at the top of the curb helps to quickly guide rainwater to both sides of the culvert, preventing waterlogging and potential water damage problems, and improving the efficiency and reliability of the culvert in the urban drainage system.
[0031] Working principle: The culvert structure mainly consists of a longitudinal section, a single - hole culvert plane, and wing walls. Among them, the first wing wall foundation and the second wing wall foundation adopt reinforced reinforced concrete structures, providing the bearing capacity and durability required for the culvert. The hot asphalt layer coated on the outer surface of the first wing wall foundation provides additional waterproof and anti - corrosion protection for the structure, ensuring the performance of the culvert under harsh climate conditions. The cut - off wall of the culvert is designed with a number of drainage holes, which can achieve precise control and guidance of water flow according to the actual water flow situation, preventing floods and optimizing the flood discharge capacity under high - flow conditions. The paving at the entrance under the single - hole culvert plane uses anti - slip and wear - resistant materials, which not only improves the passing safety of the culvert but also provides a stable passing environment for pedestrians and vehicles. The drainage groove design at the top of the curb helps to guide rainwater to both sides of the culvert, effectively preventing waterlogging and water damage problems. The wing wall is designed with different inclination angles according to different terrain and water flow conditions. This design optimizes the hydrodynamic characteristics, reduces the impact of water flow on the culvert structure, and extends the service life of the structure. The connection between the wing wall and the longitudinal section adopts a special sealing structure, preventing leakage problems and ensuring the sealing and waterproof performance of the culvert.
