Description

TECHNICAL FIELD

[0001] The application relates to a culvert structure. BACKGROUND

[0002] A culvert refers to a kind of cylinder-shaped structure made of reinforced concrete and buried underground, commonly known as a cement pipe. During construction, multiple culverts are connected and assembled to form a pipeline.

[0003] The culvert plays an important role in current farmland irrigation. In rural areas, the culvert is often buried under the roadbed between fields, serving as a water system to irrigate multiple fields. The culvert has high strength, and the soil on the field road surface is easily compacted, making it convenient for pedestrians to pass through.

[0004] When a culvert is needed for a field road, technicians usually need to dig an irrigation trench and then transport the culvert into the trench. When the field road is wide, technicians need to splice at least two culverts. After splicing, the technicians fill the trench with soil and compact it to form an irrigation pipeline in the field.

[0005] Due to the loose soil in rural areas, the culvert bottom is prone to settlement. When the settlement of adjacent culverts is inconsistent, a gap or crack may occur at the splicing site of the adjacent culverts. Water flowing out of the gap may cause erosion of the field road, making it difficult for pedestrians to walk. CONTENT OF THE INVENTION

[0006] To reduce the occurrence of gaps or cracks at the splicing site of adjacent culverts, the application provides a field culvert structure.

[0007] The field culvert structure provided by the application adopts the following technical solutions:

[0008] A field culvert structure includes multiple culvert bodies and multiple connecting components for fixing adjacent culvert bodies. One end of the culvert body is integrally formed with an extension pipe, and the extension pipe has an installation slot at the end away from the culvert body. The adjacent culvert bodies are inserted into the installation slot.

[0009] By adopting the above technical solutions, the extension pipe integrally formed at one end of the culvert body and the installation slot enable the adjacent culvert bodies to be tightly inserted. This insertion method not only enhances the stability of the structure but also reduces the occurrence of gaps when the culvert settles slightly. Even if the settlement is inconsistent, the insertion structure can maintain the tight connection between the culverts to some extent, preventing water from flowing out of the gap.

[0010] In addition, the fixing effect of the connecting assembly further enhances the stability between the culverts, which not only tightly fixes the adjacent culverts together, but also provides a certain supporting force when the culverts settle, thereby reducing the expansion of the gap.

[0011] Optionally, the connecting assembly comprises a U-shaped plate and two threaded rods, the extension pipe and the outer wall of the adjacent culvert body are both provided with positioning rings, the U-shaped groove of the U-shaped plate is sleeved on the outer wall of the two positioning rings, the two threaded rods are both threadedly installed on the U-shaped plate, and the side of the two positioning rings away from each other is both provided with a positioning groove for inserting the threaded rod.

[0012] By adopting the above technical scheme, the two threaded rods of the U-shaped plate are respectively inserted into the two positioning grooves, which can clamp the two positioning plates between the two threaded rods, so that the adjacent culvert body can be stably inserted into the installation groove, thereby avoiding the situation that the two adjacent culvert bodies move away from each other when the culvert settles.

[0013] Optionally, the positioning groove is annularly arranged.

[0014] By adopting the above technical scheme, by arranging the positioning groove in an annular manner, the threaded rod can be inserted into different positions of the positioning plate, thereby avoiding the need to rotate the two adjacent culvert bodies to align the positioning grooves of the two positioning plates, and improving the connection efficiency of the two culvert bodies.

[0015] Optionally, the inner wall of the positioning groove is provided with a first rubber layer.

[0016] By adopting the above technical scheme, by arranging the first rubber layer, the friction between the end of the screw rod and the inner wall of the positioning groove can be increased, thereby avoiding the situation that the threaded rod freely rotates in the positioning groove after the two positioning plates are clamped between the two threaded rods, and improving the stability of the connecting assembly installed on the outer wall of the culvert body.

[0017] Optionally, the U-shaped plate is provided with a threaded groove in communication with the U-shaped groove, the threaded rod is threadedly installed in the threaded groove, the inner wall of the threaded groove is provided with an elastic groove, and the elastic groove is inclinedly provided with an elastic sheet for abutting against the outer wall of the threaded rod.

[0018] By adopting the above technical scheme, by arranging the inclined elastic sheet, the loosening of the threaded rod can be reduced after long-term use, that is, the possibility of rotation and disengagement of the threaded rod from the threaded groove is reduced, thereby improving the stability of the connection between the two adjacent culvert bodies.

[0019] Optionally, the inner wall of the installation groove is provided with a second rubber layer.

[0020] By adopting the technical scheme, the second rubber layer is arranged, the sealing performance of the adjacent culvert bodies inserted into the installation grooves is improved, and the water flow from the gap between the two culvert bodies to the outside is reduced.

[0021] Optionally, the culvert body is arranged obliquely.

[0022] By adopting the technical scheme, the culvert body is arranged obliquely, so as to guide the water in the water channel into the farmland for irrigation.

[0023] Optionally, the outer wall of the culvert body is wrapped with oil felt.

[0024] By adopting the technical scheme, the oil felt is arranged, the outer wall of the culvert body is protected, the friction between the soil and the culvert is increased, the sliding or displacement of the culvert in the soil is reduced, and the stability of the overall structure is improved.

[0025] In summary, the present application has at least one of the following beneficial technical effects:

[0026] 1. The installation groove is inserted into the adjacent culvert body, which not only enhances the stability of the structure, but also reduces the gap through the interaction of the insertion parts when the culvert is slightly settled. Even if the settlement is inconsistent, the insertion structure can maintain the close connection between the culverts to some extent, preventing water flow from the gap.

[0027] 2. The elastic sheet arranged obliquely can reduce the disengagement of the threaded rod from the threaded groove after long-term use, and improve the stability of the connection between the two adjacent culvert bodies.

[0028] 3. The first rubber layer is arranged, which can increase the friction between the end of the screw rod and the inner wall of the positioning groove, avoid the free rotation of the threaded rod in the positioning groove after the two positioning plates are clamped between the two threaded rods, and improve the stability of the connection assembly installed on the outer wall of the culvert body.

[0036] The outer wall of the culvert body 1 is wrapped with an oil felt 11, so as to protect the outer wall of the culvert body 1 and increase the friction between the soil and the culvert, thereby improving the stability of the overall structure.

[0037] An extension pipe 12 is integrally formed at one end of the culvert body 1, the extension pipe 12 is provided with a mounting groove 13 at an end away from the culvert body 1; adjacent culvert bodies 1 are inserted into the mounting groove 13, and a second rubber layer 14 is arranged on the inner wall of the mounting groove 13, so as to increase the sealing property between the adjacent culvert bodies 1 and the inner wall of the mounting groove 13 and prevent water flow from flowing out of the gap.

[0038] Referring to Figure 2 The connecting assembly 2 comprises a U-shaped plate 3, two threaded rods 4 and two positioning rings 5, the two positioning rings 5 are respectively arranged on the outer walls of the extension pipe 12 and the adjacent culvert body 1; positioning grooves 51 are arranged on the sides of the two positioning rings 5 away from each other, the positioning grooves 51 are arranged in a ring shape, and a first rubber layer 52 is arranged on the inner wall of the positioning groove 51.
