Description

Technical Field

[0001] This utility model relates to the field of farmland bridge and culvert technology, and in particular to a water diversion wing wall for a farmland bridge. Background Technology

[0002] Traditional rural irrigation ditches are mostly earthen ditches or simple brick and stone ditches. Due to long-term rainwater erosion and silt deposition, they generally suffer from serious water leakage and poor drainage. The supporting facilities at the intersection of field roads and irrigation ditches were mostly simple culverts, temporary stone slab bridges or earthen dams in the early days. These facilities not only had extremely poor structural stability, but also had narrow cross sections and limited load-bearing capacity. With the popularization of agricultural mechanization, large tractors, seeders and other agricultural machinery have become increasingly common. These traditional intersection facilities often have insufficient width and load-bearing capacity, which obstructs the movement of agricultural machinery in the fields. They can only detour or transport agricultural materials manually, which greatly increases labor costs and seriously affects agricultural production efficiency. Many existing agricultural bridges built decades ago are limited by the technology and funding available at the time, resulting in low design loads and weak foundations. They face problems such as water erosion and foundation settlement. Moreover, most of them lack necessary supporting facilities such as weight limit warnings and seepage prevention and protection. After exceeding their service life, they are prone to damage and collapse, which seriously threatens the safety of farmers and agricultural production.

[0003] Therefore, we propose a water diversion wing wall for agricultural bridges. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a water diversion wing wall for agricultural bridges.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A water diversion wing wall for an agricultural bridge includes a culvert and a bridge deck. The culvert includes a thick coarse sand cushion layer, a concrete wing wall, and a concrete cap. The bottom of the culvert is covered with a thick coarse sand cushion layer, which is 200mm thick. The concrete wing walls are arranged symmetrically on top of the thick coarse sand cushion layer. A concrete cap is installed on the inner side of the top of the concrete wing wall. A three-felt, four-coat waterproof layer is provided at the connection between the concrete wing wall and the concrete cap.

[0006] As a further improvement of this utility model: a gabion bottom is provided in the middle section of the inner side of the concrete wing wall, and the gabion bottom is 300mm thick.

[0007] As a further embodiment of this utility model: the bridge deck includes a bridge slab and reinforcing bars, the bridge slab is installed on the top of the concrete cap, the bridge slab is provided with several sets of reinforcing bars inside, and the bridge slab is formed by pouring concrete.

[0008] As a further improvement of this utility model: field roads are provided on both sides of the bridge deck, and the bridge deck and the field roads are smoothly connected, with the longitudinal slope of the connecting section of the road not exceeding 5%.

[0009] As a further embodiment of this utility model: a weight-limiting plate is installed on one side of the top of the bridge culvert, a red-background, white-letter reflective film is pasted on the front of the weight-limiting plate, a galvanized steel pipe is welded to the bottom of the weight-limiting plate, and a concrete pier is provided at the bottom of the galvanized steel pipe.

[0010] As a further improvement of this utility model: a pavement layer is provided above the bridge deck, and several sets of steel bars are provided inside the pavement layer.

[0011] Compared with the prior art, this utility model provides a water diversion wing wall for agricultural bridges, which has the following beneficial effects: This utility model, through symmetrically arranged concrete wing walls paired with a 200mm thick coarse sand cushion layer, provides a stable foundation for the overall structure and accommodates minor settlement. The three-felt, four-oil waterproof layer at the connection between the inner concrete cap at the top and the wing walls, with the combination of multiple layers of felt and asphalt, achieves strong seepage and moisture prevention, ensuring long-term stability of the structural connection. The 300mm thick gabion bottom protection in the middle section of the inner side has excellent permeability and flexibility, effectively resisting water erosion. The bridge deck and pavement layer are reinforced with multiple sets of steel bars and poured with concrete, significantly improving structural strength and load-bearing capacity, and enhancing durability. The bridge deck smoothly connects to the field road with a longitudinal slope of no more than 5%, ensuring smooth and convenient passage and meeting the traffic needs of agricultural machinery in the field.

[0017] Example: A water diversion wing wall for an agricultural bridge, such as Figures 1-4 As shown, the bridge includes a culvert 1 and a bridge deck 2. The culvert 1 includes a thick coarse sand cushion layer 101, concrete wing walls 102, and a concrete cap 103. The bottom of the culvert 1 is covered with a thick coarse sand cushion layer 101, which is 200mm thick. The concrete wing walls 102 are symmetrically arranged on top of the thick coarse sand cushion layer 101. The concrete cap 103 is installed on the inner side of the top of the concrete wing walls 102. A three-felt four-oil waterproof layer 104 is installed at the connection between the concrete wing walls 102 and the concrete cap 103. The 200mm thick coarse sand cushion layer 101 ensures the stability of the structural foundation. The symmetrical concrete wing walls achieve soil retention and smooth flow. The three-felt four-oil waterproof layer 104 blocks water penetration and protects the structure. The concrete cap strengthens the load-bearing connection and adapts to the needs of agricultural machinery passage and field operations, ensuring smooth road access, safe travel for farmers, and improving the damage resistance and service life of the facilities.

[0018] like Figures 1-4 As shown, a gabion bottom protection 3 is provided on the inner middle section of the concrete wing wall 102. The gabion bottom protection 3 is 300mm thick. Through its flexible structure and excellent permeability, it disperses the impact force of water flow to resist the scouring of the riverbed, adapts to slight deformation of the foundation to avoid structural damage, reduces construction and later maintenance costs, and ensures the long-term stable operation of the water diversion wing wall.

[0019] like Figures 1-4As shown, the bridge deck 2 includes a bridge slab 201 and reinforcing bars 202. The bridge slab 201 is installed on top of the concrete cap 103. Several sets of reinforcing bars 202 are installed inside the bridge slab 201. The bridge slab 201 is formed by pouring concrete. The bridge slab 201, which is formed by pouring concrete and has multiple sets of reinforcing bars 202 installed on top of the concrete cap, greatly improves the load-bearing strength and deformation resistance of the bridge deck 2 by leveraging the synergistic force-bearing characteristics of the reinforcing bars 202 and concrete. It can effectively withstand the impact of loads from agricultural machinery, while ensuring the structural integrity and stability of the bridge deck 2, avoiding damage and cracking during use, providing solid and reliable support for vehicle and personnel passage, adapting to the high-frequency use needs of field operations, and extending the service life of the bridge deck 2.

[0020] like Figures 1-4 As shown, field roads 4 are provided on both sides of the bridge deck 2. The bridge deck 2 and the field roads 4 are smoothly connected. The longitudinal slope of the connecting section is no more than 5%. The smooth connection between the bridge deck 2 and the field roads 4 and the longitudinal slope of the connecting section are no more than 5% ensure smooth and convenient passage and meet the traffic needs of agricultural machinery in the field.

[0021] like Figures 1-4 As shown, a weight limit plate 5 is installed on one side of the top of the bridge culvert 1. A red-background, white-letter reflective film 6 is affixed to the front of the weight limit plate 5. A galvanized steel pipe 7 is welded to the bottom of the weight limit plate 5. A concrete pier 8 is installed at the bottom of the galvanized steel pipe 7. By attaching the red-background, white-letter reflective film 6 to the weight limit plate 5 on one side of the top of the bridge culvert 1, clear warnings can be provided both day and night, reducing safety hazards.

[0022] like Figures 1-4 As shown, a pavement layer 9 is provided above the bridge deck 201. Several sets of steel bars 202 are provided inside the pavement layer 9. Through the pavement layer 9 with multiple sets of steel bars 202 built into the bridge deck 201, the pavement layer 9 is enhanced to resist deformation and shear, prevents rainwater from penetrating and corroding the internal structure of the bridge deck 201, and further improves the overall stability and durability of the bridge deck 2.

[0023] Working principle: The bridge culvert 1, with its symmetrically arranged concrete wing walls and a 200mm thick coarse sand cushion layer 101, provides a stable foundation for the overall structure and accommodates minor settlement. The three-layer felt and four-layer asphalt waterproof layer 104 at the connection between the inner concrete cap and the wing wall, through the combination of multiple layers of felt and asphalt, achieves strong seepage and moisture prevention, ensuring long-term stability at the structural connection. The inner middle section has a 300mm... The thick gabion base 3 has excellent permeability and flexibility, which can effectively resist water erosion. The bridge deck 2's bridge plate 201 and pavement layer 9 are both built with multiple sets of steel bars 202 and are poured with concrete, which greatly improves the structural strength and load-bearing capacity, and has strong durability. The bridge deck 2 and the field road 4 are smoothly connected and the longitudinal slope of the connection section is no more than 5%, ensuring smooth and convenient passage and meeting the traffic needs of agricultural machinery in the field. The weight limit plate 5 on one side of the top of the bridge culvert 1 is covered with a red background and white letter reflective film 6, which can be clearly warned during the day and at night. Combined with the stable support of galvanized steel pipe 7 and concrete piers, it can effectively regulate the traffic load, avoid structural overload damage, and extend its overall service life.
